In the modern home office, there is a specific, nagging desire that Herman Poppleberry and Corn describe as the "itch for the perfect information radiator." It is the dream of a dedicated screen that glows softly on a desk or wall, providing vital data—calendars, time zones, task lists, and weather—without the friction of unlocking a phone or switching browser tabs. However, as Herman and Corn discuss in their latest episode, achieving this "starship command center" feel is surprisingly difficult in the current market.

The Goldilocks Problem of Hardware

The discussion begins by identifying a massive gap in the market. On one end of the spectrum, users find boutique, ready-made hardware that often costs upwards of $400. While these devices are aesthetically pleasing, they frequently lock users into proprietary ecosystems. As Corn points out, this creates a "flexibility tax." If a user wants a custom widget that the manufacturer doesn't support, they are out of luck. Furthermore, if the company ceases operations, the expensive device becomes little more than a "pretty paperweight."

On the other end of the spectrum is the "scrappy" DIY route, typically involving a Raspberry Pi or an Orange Pi. While affordable and flexible, these projects often result in what Corn calls a "science fair experiment gone wrong"—a mess of green circuit boards and hanging cables that detracts from a professional office environment. The challenge for the modern "prosumer" is finding the middle ground: quality and polish without the corporate subscriptions or the cable-sprawled chaos.

The Case for Ambient Technology: E-Ink

Herman highlights E-ink as a primary contender for the ideal dashboard. Unlike traditional LCD or OLED monitors, E-ink is "ambient technology." It doesn’t flicker or glow, giving it a paper-like quality that reduces digital eye strain in an already screen-heavy environment.

A common criticism of E-ink is its slow refresh rate, but Herman explains that the technology has advanced significantly by 2026. Newer panels, such as those from the Inkplate series or Waveshare, utilize "partial refreshes" that allow for sub-one-second updates. This makes them perfectly viable for ticking clocks and updating schedules. When paired with a cheap, Wi-Fi-enabled ESP32 microcontroller, an E-ink display can operate for months on a small battery, providing a wireless, minimalist solution for under a hundred dollars.

Repurposing Tablets as Appliances

For those who find microcontrollers too technical, the hosts suggest repurposing budget-friendly tablets, like the Amazon Fire or older Android models. The key, Herman argues, is treating the tablet as an "appliance" rather than a computer.

By using specialized software like the Fully Kiosk Browser, a standard tablet can be stripped of its distractions—notifications, home buttons, and status bars—to become a dedicated display. This software can even turn the tablet's front-facing camera into a motion sensor, allowing the screen to wake up only when someone enters the room. This approach bridges the gap between DIY and professional installation, making a $100 tablet feel like a high-end custom integrated system.

Software Freedom and the "End of SaaS"

A significant portion of the conversation focuses on the "Everything as a Service" fatigue. Many commercial dashboard solutions require monthly subscriptions just to display the user's own data. Herman and Corn advocate for self-hosted, open-source alternatives like Home Assistant and MagicMirror².

Home Assistant has evolved from a clunky, technical tool into a sophisticated platform with drag-and-drop interfaces. It allows users to pull in data from Google Calendars, email servers, and even local hardware sensors without any recurring fees. For those who want even more customization, MagicMirror² offers thousands of community-made modules for everything from tracking the International Space Station to monitoring Todoist lists.

The AI Revolution in Tool Building

Perhaps the most forward-looking insight from the episode is the shift toward AI-driven dashboard creation. Daniel, a friend of the show, suggested that we are entering an era where users no longer buy software off the shelf but create it on the fly.

Corn expands on this by explaining how Large Language Models (LLMs) have simplified the coding process. Instead of spending hours writing Python scripts, a user can simply describe their ideal dashboard to an AI, which can then generate the necessary HTML and CSS code in seconds. This "end of SaaS" philosophy empowers individuals to host their own simple, custom web pages on their local networks, completely bypassing the need for third-party platforms.

Conclusion

The quest for the perfect information radiator is about more than just seeing the time; it is about reducing cognitive load and creating a workspace that feels intentional. Whether through the low-power elegance of E-ink, the repurposed utility of an Android tablet, or the infinite flexibility of AI-generated code, the middle ground for productivity dashboards is more accessible than ever. As Herman and Corn conclude, the best tools are the ones that disappear into our environment, providing exactly what we need, right when we need it.

Episode #649: The Ultimate Dashboard: DIY Information Radiators

Daniel Daniel's Prompt
Daniel
I’d love to pick your brains about the different ways one can go about creating a productivity display or dashboard, like a desktop or wall panel that shows things like time zones, emails, and calendars.

I’ve looked at several options: expensive ready-made hardware solutions that aren't very customizable; using a Raspberry Pi with digital signage tools, which are often meant for offices and require costly subscriptions; Android tablets, which can be overkill and expensive; and separating the display and compute using something like an Orange Pi, which can feel a bit scrappy.

I’m looking for a middle ground—something like an Android tablet with built-in Wi-Fi and compute that is customizable and affordable for a home office. What hardware and software would you recommend for someone looking for a nice, customizable display without the high cost of subscriptions or the complexity of certain self-hosted setups?
Corn
You know, Herman, I was looking at my desk the other day and I realized I have this persistent, nagging itch. It is the itch for the perfect information radiator. That one screen that just sits there, glowing softly, telling me exactly what I need to know without me having to alt-tab, unlock my phone, or dig through a dozen browser tabs. It is such a specific, modern desire, right? This quest for the ultimate, low-friction productivity dashboard.
Herman
Oh, I know that itch well, Corn. It is the dream of the command center. It is the desire to feel like the captain of a starship, where all the vital signs of your life and work are visible at a glance. I am Herman Poppleberry, by the way, for anyone joining us for the first time, and yeah, this is a rabbit hole I have fallen down more times than I care to admit. It is funny you bring it up, because our housemate Daniel actually sent us a prompt about this very thing. He is tired of the extremes. On one side, you have the super expensive enterprise stuff, and on the other, you have the messy, cable-sprawled hobbyist projects that look like a science fair experiment gone wrong.
Corn
It is a classic Goldilocks problem. Daniel was asking about how to find that elusive middle ground. He has looked at the ready-made hardware that costs four hundred dollars and locks you into a limited, proprietary ecosystem. Then he looked at the Raspberry Pi route with digital signage tools, which are usually meant for corporate lobbies and come with those annoying ten dollar a month subscriptions just to show your own data. It feels like there is a massive gap in the market for the "prosumer" who wants quality without the corporate overhead.
Herman
Exactly. And then you have the tablet route, which feels like it should be the easy answer, but often ends up being either too much or just slightly wrong for a dedicated display. Daniel mentioned this idea of moving toward an era where we do not just buy software off the shelf, but we kind of create the tools we need on the fly. He called it the end of software as a service, in a way. I think there is a lot of truth in that, especially here in early twenty twenty-six, with how easy it is becoming to stitch things together with simple code or even artificial intelligence helpers.
Corn
Right, and he is specifically looking for something customizable and affordable for a home office. Something that shows time zones, calendars, maybe even a snippet of your inbox or your task list, but without the friction of a full computer interface. So today, I think we should really dig into what that middle ground looks like right now. What is the actual state of the art for a person who wants a beautiful, functional dashboard without a degree in electrical engineering or a corporate expense account?
Herman
I love this topic because it sits right at the intersection of productivity psychology and hardware hacking. Let us start by looking at why the existing solutions feel so unsatisfying. Why do you think the expensive ready-made stuff fails for someone like Daniel?
Corn
I think it is the flexibility tax. When you buy a dedicated productivity screen from a boutique company, you are paying for the industrial design and the ease of setup. But as soon as you want to add a widget that they do not support, like maybe a specific countdown timer for your next sprint or a custom feed from a niche tool you use, you are stuck. You are a prisoner of their development roadmap. If they decide to go out of business or stop supporting that model, your expensive screen becomes a very pretty paperweight.
Herman
And the enterprise signage stuff is even worse for home use. Those companies like Yodeck or others, they are built for managing a thousand screens in a thousand office buildings. They want to sell you a subscription because that is their business model. For a home user, paying over a hundred dollars a year just to show your own calendar on a wall feels like an insult. It is your data, on your screen, in your house. Why am I paying rent for that? It is the "everything is a service" fatigue that Daniel is talking about.
Corn
Precisely. So that leads a lot of people to the Raspberry Pi or the Orange Pi, what Daniel called the scrappy route. And I get why he calls it that. Unless you are really good at three-D printing a custom enclosure, you usually end up with a green circuit board taped to the back of a monitor with a messy bundle of cables hanging down. It does not exactly scream professional home office. It screams "I spend more time fixing my dashboard than looking at it."
Herman
It is the cable management nightmare. But, let us talk about the compute side for a second. Daniel mentioned separating the display and the compute. This is actually a really smart architectural move, even if it feels scrappy. If you have a screen that is just a screen, you can upgrade the brains behind it whenever you want. But I think the real breakthrough for the middle ground in twenty twenty-six is actually in the world of smart home tablets and repurposed hardware.
Corn
Are you thinking about the cheap Android tablet route? Daniel seemed a bit wary of that being overkill. He mentioned that tablets can feel like too much computer for a simple task.
Herman
It can be overkill if you just leave it as a tablet. If you have notifications popping up, or if the battery starts to swell because it is plugged in twenty-four seven, it is a disaster. But if you treat a tablet as an appliance rather than a computer, the game changes. Specifically, I am looking at things like the newer e-ink tablets or even the budget-friendly Fire tablets that people are stripping down.
Corn
Okay, let us go deeper on the e-ink side first. I know you have a soft spot for e-ink. Why is that a strong contender for a productivity dashboard in a home office?
Herman
E-ink is the ultimate ambient technology. It does not glow at you, it does not flicker, and it has that high-contrast, paper-like quality that just feels less stressful. In a home office, where you are already staring at two or three backlit monitors for eight hours a day, having another glowing rectangle can actually be a negative. It adds to the digital noise. E-ink looks like a part of your wall or your desk. And from a technical perspective, once you set the image, it stays there with zero power consumption. You could have a power outage and your schedule for the day would still be visible.
Corn
But isn't the refresh rate a huge hurdle for something like a dashboard? If I get a new email, I do not want to wait thirty seconds for the screen to flash black and white and slowly update. That feels like the opposite of a high-tech dashboard.
Herman
That is the old school way of thinking about e-ink. The newer panels we are seeing now, especially the ones coming out of companies like Waveshare or the Inkplate series, can do partial refreshes very quickly. We are talking about sub-one-second updates for small areas of the screen. So, your clock can tick, your calendar can update, and it feels fluid enough for productivity. There are even color e-ink displays now, like the Spectra six series, that look incredible for showing color-coded calendars or weather maps.
Corn
Okay, so if we take Daniel's request for a middle ground, maybe an e-ink display paired with an ESP thirty-two controller? Daniel mentioned the ESP thirty-two specifically. For the listeners who might not know, that is a tiny, very cheap microcontroller with built-in Wi-Fi.
Herman
Exactly. And that is where the magic happens. You can get an ESP thirty-two and a seven-point-five-inch e-ink display for well under a hundred dollars. There is this amazing open-source project called Open EPaper Link that basically lets you run these things for months on a tiny battery. You can push images to them over Wi-Fi from a central server. It is very customizable, but I will admit, it requires a little bit of coding knowledge. It might still be a bit too "scrappy" for someone who wants a polished experience.
Corn
See, that is the tension. Daniel wants something that feels integrated. What about the software layer? If we assume the hardware is some kind of screen with a basic computer attached, how do we solve the subscription and customization problem without spending forty hours writing Python scripts?
Herman
This is where we have to talk about the heavy hitters in the self-hosted world. Have you looked at what people are doing with Home Assistant dashboards lately? It has completely moved beyond just turning on lights.
Corn
I have! It has evolved so much in the last year. It used to be this very clunky, technical interface where you had to edit YAML files for everything, but now with the sections view and the new drag-and-drop features, people are building truly beautiful interfaces. And the best part is that Home Assistant can pull in everything. It can talk to your Google Calendar, it can check your IMAP mail server, it can pull in weather, and it can even monitor your computer's CPU usage or your solar panel output.
Herman
And it is all local. No subscription. You run it on a small server in your house, like an old laptop or a cheap mini PC, and then any device with a web browser becomes your dashboard. This, I think, is the real answer for Daniel. You get a decent, slim Android tablet—maybe a refurbished one from a few years ago to keep the cost down. You mount it to the wall or put it on a nice stand. Then, you use an app called Fully Kiosk Browser.
Corn
Oh, Fully Kiosk is a game changer for this specific use case. Tell the people why it is better than just opening Chrome on a tablet.
Herman
Fully Kiosk Browser basically turns an Android tablet into a single-purpose appliance. It strips away the status bar, the home buttons, and all the distractions. It just displays one website, which would be your Home Assistant dashboard, or maybe a custom web app you built. But here is the cool part: it gives the website access to the tablet's hardware. It can even use the tablet's front camera as a motion sensor. So, when you walk into your office, the screen turns on instantly, and when you leave, it goes dark to save the screen and the power. It makes a hundred-dollar tablet feel like a two-thousand-dollar custom installation.
Corn
That sounds like exactly the middle ground. You get the polish of a tablet, the flexibility of a web-based dashboard, and no monthly fees. But what if Daniel doesn't want to manage a whole Home Assistant setup? That can be a bit of a project in itself. Are there simpler web-based tools that are still customizable?
Herman
There are. DAKboard is the most famous one, and while they do have a subscription model, their free tier is actually quite capable for a single screen. You can link your calendar, show the weather, and put some photos on there. But if Daniel really wants to embrace the "end of SaaS" philosophy he mentioned, he should look at MagicMirror squared. It is an open-source platform that has thousands of community-made modules. You want a module that shows the current position of the International Space Station? Someone has built it. You want your Todoist list? It is there.
Corn
I also want to touch on what Daniel said about creating tools on the fly. We are seeing these new AI-driven dashboard builders now. You can essentially tell an LLM, "Hey, I want a dashboard that shows my primary calendar, the time in Jerusalem, London, and New York, and a list of my top three most recent emails from my boss." The AI can actually generate the HTML and CSS for that dashboard for you in seconds. You don't even need a platform like DAKboard anymore. You can just host a simple text file on your local network.
Herman
That is a brilliant point, Corn. We are moving away from needing a company to build a widget for us. If you can describe it, you can probably get it rendered. And for someone like Daniel, who seems technically curious, that opens up a world of hyper-personalization. Like, imagine a dashboard that changes its layout based on what is on your calendar. If you have a day full of meetings, the calendar expands to take up the whole screen. If your day is clear, it switches to a deep-work timer and a list of your most important tasks. This is what I call "context-aware" productivity.
Corn
That is the dream. That is where it becomes a true productivity partner, not just a passive display. But let's get practical for a second. If you were Daniel, and you wanted to set this up this weekend, what is the specific hardware stack you are buying? Let's give him a shopping list.
Herman
Okay, here is my mid-range, high-value recommendation for twenty twenty-six. First, for the screen, I would actually move away from the tablet and look for a portable monitor. You can find fifteen-inch four-K portable monitors now for under a hundred and fifty dollars. They are incredibly thin, they look great, and they usually power over a single USB-C cable.
Corn
Okay, a portable monitor. It is bigger than a tablet, which is nice for a wall or a large desk. And what is the brain?
Herman
I would go with a mini PC, specifically something with an Intel N-one-hundred processor. These things have become the gold standard for low-power home computing. They are about the size of a sandwich, they use almost no power, and they are much more powerful and stable than a Raspberry Pi. You can VESA mount it right to the back of the monitor so it is completely hidden. You run a lightweight version of Linux on it, and you just have it open a browser in kiosk mode on startup.
Corn
Why the mini PC over the Raspberry Pi five? Is it just the performance, or is there more to it?
Herman
It is the stability and the "it just works" factor. Raspberry Pis are great, but microSD cards can fail over time if they are writing data constantly, and the ARM architecture sometimes makes installing certain software a bit finicky. An Intel-based mini PC is just a standard computer. Everything works. You have plenty of RAM, you have a real SSD, and you can use it for other things in the background, like a local file server or a media player, without it breaking a sweat. It is the ultimate "set it and forget it" brain for a dashboard.
Corn
That makes sense. So you have a fifteen-inch screen, a mini PC hidden behind it, and you are running a custom dashboard. Total cost is probably around two hundred and fifty to three hundred dollars. It is not cheap, but it is a one-time cost and it is incredibly powerful. It is less than the price of those locked-down boutique screens.
Herman
Exactly. And if you want to go even cheaper, the true middle ground is definitely the repurposed tablet. You can find an old iPad or a high-end Samsung tablet from three years ago on the used market for a hundred dollars. The screens on those are often better than any cheap monitor you can buy. You wall-mount it with a thirty-dollar magnetic mount, and you are in business. The key is the mounting.
Corn
I think we should talk about the aesthetics for a moment too. Daniel mentioned he wants it to look nice. The wall-mounting part is where most people fail. They have a white wire trailing down a blue wall, and it looks like an afterthought. If you are in a rental, you cannot always drill holes to hide cables.
Herman
This is where flat, paintable ribbon cables come in. You can get these USB power cables that are basically as thin as a piece of tape. You stick them to the wall, paint over them with a little bit of leftover wall paint, and they virtually disappear. It is a pro-level trick that makes a DIY setup look like a thousand-dollar integrated solution. Or, if you are using a tablet, look for "PoE to USB-C" adapters. If you have Ethernet in your walls, you can send power and data over a single thin cable.
Corn
That is a great tip. Now, let's talk about the data privacy aspect. Daniel mentioned that in an office, you wouldn't want your inbox on a public screen. Even in a home office, if you have guests over or if you use your office for other things, you might want some privacy. How do we handle that in a customizable way?
Herman
That is the beauty of the DIY approach. You can build in a privacy mode. If you are using Home Assistant or a custom web app, you can have a simple toggle on the screen. Or better yet, use the presence detection we talked about. There are these amazing new mmWave sensors, like the LD-twenty-four-ten, that can detect if a human is standing still in a room. If your phone isn't in the room or the sensor doesn't see you, the dashboard switches to a generic clock or a rotating art gallery. As soon as you walk in, the dashboard recognizes your presence and brings up your personal calendar and emails.
Corn
That is very slick. It feels very futuristic, but it is actually quite easy to do now with Bluetooth room-tracking or those presence sensors. It solves that psychological barrier of having your life on display.
Herman
It really does. And it addresses Daniel's concern about things being "overkill." It is only a computer when you are there to use it; the rest of the time, it is just art. I want to go back to Daniel's mention of the ESP thirty-two and MQTT. For the really nerdy listeners, this is where you can get very creative. You can have physical buttons on your desk that talk to the dashboard via MQTT. You press a physical button that says "Focus Mode," and your dashboard changes, your lights dim, and your status on Slack updates to "away."
Corn
I love that. It is about creating an environment, not just a screen. But, I wonder if we are making it sound too complicated again. If Daniel wants to start simple, what is the one software tool he should look at first?
Herman
Honestly, if he wants to start today without setting up a server, he should check out a service called Dakboard. Just use the free version on an old tablet. But if he wants the customization he's talking about—the "end of SaaS" feel—he should spend a Saturday afternoon learning the basics of Home Assistant. It has a bit of a learning curve, but once you get it, you will never want to go back to a closed system. There are thousands of YouTube tutorials specifically for "Home Assistant Dashboards for Beginners."
Corn
And there are so many templates now. You don't have to start from a blank canvas. You can find someone else's beautiful productivity dashboard layout on a forum, copy their code, and just swap in your own data sources. It is very much like the way people share Notion templates or Obsidian workflows. It is a community of people trying to solve the same problem.
Herman
Exactly. It is a community-driven ecosystem. And since Daniel mentioned the end of software as a service, I think this is the ultimate expression of that. You are the architect. You are using open-source blocks to build a tool that fits your brain perfectly. No company can build a dashboard that fits every person's workflow, because we all process information differently. Some people are visual and want a big weather map. Others are text-heavy and want a list of their next five tasks.
Corn
I think that is a really profound point, Herman. The perfect productivity display is as personal as a journal. It is a reflection of how you prioritize your time and energy. If you value your time, spending a few hours building a tool that saves you thirty seconds of "searching" fifty times a day is a massive win.
Herman
It really is. And I think we are seeing a shift where people are willing to put in a little bit of effort to get that personalization. The middle ground is no longer about settling for a mediocre product; it is about having the tools to build a superior one without needing to be a professional developer. We have moved past the "scrappy" phase into the "empowered" phase.
Corn
So, to summarize for Daniel, we have two main paths for the middle ground. Path one is the tablet appliance. Buy a good used tablet, wall-mount it with a magnetic mount and a hidden cable, and use Fully Kiosk Browser to display a Home Assistant dashboard. This gives you touch control and a high-resolution screen for about a hundred and fifty dollars total.
Herman
And path two is the modular display. A fifteen-inch portable monitor paired with a tiny Intel mini PC hidden behind it. This gives you a much larger canvas, more compute power, and more stability for twenty-four seven operation. This is the "Pro" setup for around three hundred dollars. Both of these avoid monthly subscriptions and give you total control over your data.
Corn
I think those are both fantastic options. And they both satisfy that desire to move away from the rigid boxes that traditional software puts us in. You are creating a tool that works for you, rather than you working around the tool. It is about reclaiming your digital space.
Herman
Precisely. And hey, if you are listening to this and you have built your own dashboard, we would love to see it. One of the best parts of this community is seeing the creative ways people display their information. You can reach out to us through the contact form at myweirdprompts dot com. Send us a photo or a description of your stack!
Corn
Yeah, I am always looking for new widget ideas. I have been trying to figure out a way to show my water intake versus my coffee intake on my dashboard in real-time, but it is a work in progress. I think I need some kind of smart coaster.
Herman
That sounds like a very Corn-specific widget. I love it. You probably need a smart scale under your mug for that level of precision. We can talk about the ESP thirty-two load cell integration in the next episode.
Corn
Don't give me ideas, Herman. I have enough projects on my plate. But seriously, this quest for the perfect display is really a quest for a more intentional relationship with our digital lives. By bringing the most important information out of the hidden tabs of our browsers and into the physical space of our offices, we are making it more tangible and less overwhelming.
Herman
It reduces the cognitive load of searching for information. When it is just there, in your peripheral vision, you don't have to break your flow to check the time in another zone or see when your next meeting is. It becomes a part of the environment, like a window looking out onto your digital world.
Corn
A window into your own productivity. I like that. Well, I think we have given Daniel a lot to chew on. It is a big topic, but the middle ground is definitely there if you are willing to look for it and tinker just a little bit.
Herman
Absolutely. It is an exciting time to be a tinkerer. The hardware is cheaper and better than ever, and the software is becoming more accessible every single day. You don't need to be a coder; you just need to be curious.
Corn
Before we wrap up, I just want to say a huge thank you to everyone who has been following along with us. We are over six hundred episodes in now, and the community around My Weird Prompts is just incredible.

We have the full archive there, and it is a great place to search for topics we have covered in the past. We have talked about everything from emergent AI behaviors to the physics of coffee, so there is plenty to explore.
Corn
Thanks again to Daniel for the great prompt. It is always fun to dig into these problems that sit right on the edge of what is possible for a dedicated home user. It keeps us on our toes.
Herman
Definitely. I am going to go look at some seven-color e-ink panels now. You have me inspired to upgrade my own desk setup.
Corn
Of course you are. I expect a full report by Monday. Alright, thanks for listening to My Weird Prompts. We will be back next time with another deep dive into whatever weird and wonderful ideas come our way.
Herman
See you then. Goodbye!
Corn
Goodbye everyone!
