we[1] operate out of `us-east-1` but chose to not use any of the cloud based vendor lockin (sorry vercel, supabase, firebase, planetscale etc). Rather a few droplets in DigitalOcean(us-east-1) and Hetzner(eu). We serve 100 million requests/mo, few million user generated content(images)/mo at monthly cost of just about $1000/mo.

It's not difficult, it's just that we engineers chose convenience and delegated uptime to someone else.

Your product looks so good, congratulations on your launch.

Have you considered making a standalone devices with just sensors (think data only mode) and letting the users hook up their data on any eink dashboard of their choice.

Below are some of the example of community created Air Quality dashboards[1] installable on any e-ink hardware[2].

I have to deal with bouts with amnesia myself due to a dissociative disorder - this would be a really good appliance just to be able to see reminders to myself and also reminders from friends - relationships are really difficult to keep up with when its out of sight out of mind for anyone.

I'm working on a personal dashboard right now so I can have one space to leave notes for myself - I have the problem of not being able to consistently use the same tools since there are so many to reach out (social media, sms, chat apps, trello, physical notepads, .txt files). I frequently just fully forget that I've been taking notes every day, and where they're at. Building routines is, as one can imagine, really difficult. An app requires that I'm looking at my phone and can prioritize a notification. All the apps together are just too much to be able to prioritize, and I find myself hunting through all the apps for reminders or to try to ground myself.

That's the exact reason we built TRMNL, because your phone is consistently trying to seek your attention (hence distraction). TRMNL helps build personal dashboard without necessarily creating chaos. We built handful of native integrations[1], but you can completely hack it and create your own dashboard with simple HTML content[2].

This is so great, I love it. I don't have amnesia but I have lots of trouble remembering what I was going to work on next and used an e-paper display[1] to help with that. My code is a lot simpler (as the display only has an ESP32 and that isn't particularly powerful) but it can fetch a PNG image and it can display it, so my "protocol" (which I'm hesitant to call it that) is it opens a URL named 'inkstatus.html' and looks for a link of the form "http://example.com/image.png" (sadly I can't code quote that here but you get the idea, a URL pointing to image.png from the same server. It then reads that image and displays it, if the image is the same one it displayed the previous time it just does nothing and goes back to sleep for 10 seconds.

That way, all of the rendering is done on the web server (by a cron script in my case and LaTex) and display doesn't have any fiddly html/css issues it is just putting up a full size png image which was part of the library that the Soldered guys provided.

Based on the referenced article I'm going to see if I can replicate this for my Dad who is at the age where he doesn't remember things.

I think you should also checkout TRMNL. Being engineers ourself security/privacy is of atmost concern, and we follow a similar architecture mentioned above. You could create a private plugin and send in data in the form of REST APIs[1]. You could also use your own webserver by hacking the firmware[2]

Does any commercial version of this exist? Using an existing tablet makes the DIY aspect a little less but then you have to roll your own site as well.

ronakjain90 · a year ago

You should check out usetrmnl.com. It's commercially available and has 50+ native plugins and many community driven recipes[1].

Are there any plans to have a version without the battery? It looks exactly like what I've been looking for otherwise.

Also, what country are the orders shipped from? US?

ronakjain90 · a year ago

Internally we are debating on releasing a Hackable DIY kit. Feel feel to send a message to support@usetrmnl.com.

It's shipped from USA.

Super true. One of the best tests of this is setting up a new laptop. Some of the best experiences are when you get a new laptop, and just clone the codebase and everything works as it did before, no special magic. Golang with vendored dependencies seems to be wonderful for this but I've had relatively decent experiences with newer java projects.

My worst experiences universally have always been python projects. I don't think I've had a single time where I cloned a python project and had it just work.

Beyond just the code, I've had lots of mixed experiences with CI/CD being smooth. I unfortunately don't think I've been in a single shop where deployments or ci have been a good experience. They often feel very fragile and undocumented and hard for newcomers.

Every time I setup a JS project which is older than a few years, it's

1. Extremely difficult to setup the code base, because of dependency spaghetti 2. Lot of breaking changes across different libraries, making maintenance not so easy.

Easiest projects to maintain were written on Go, Java, Ruby,
