ryanckulp··on HomeOS – A self-hosted family dashboard for a kitchen touchscreen
if TRMNL is too expensive, get a cheaper 3rd party option then:

1. flash our* OSS firmware (https://github.com/usetrmnl/trmnl-firmware) 2. spin up an OSS server client (https://docs.trmnl.com/go/diy/byos#implementations) 3. install the Home Assistant plugin (https://github.com/usetrmnl/trmnl-home-assistant)

no need to write any code or give TRMNL a penny, while still benefiting from a few years of deep dev in this area.

ryanckulp··on AI Agent – TRMNL
we can only estimate token <> cost in our cloud agent, but we also OSS'd the skills and in those cases the cost is ~$0 (part of one's LLM subscription): https://github.com/usetrmnl/trmnl-agent-skills

the agent also has a model switcher, and the estimate you quoted is based on Haiku when we launched.

ryanckulp··on AI Agent – TRMNL
i founded TRMNL and didn't try AI myself until ~2 months ago. i'd rather shut down down and open source everything (per our Unbrickable Pledge) than become "just another AI company."

the AI Agent exists to empower less technical folks to turn their vision into reality, and we're proud of what's possible with it. meanwhile our top community developers continue to hand craft beautiful, useful plugins for everyone to install, LLM free.

ShipHero doesn't even have an SLA, not too concerned.

thanks for reading, updating the post now to explain we use the Superpowers skill and spend 90% of our effort on specs / tests. measure thrice, cut once.

i’m a happy Together Letters user, in an Atlanta founder group. didn’t realize until this post that there are thousands of us, well played.
ryanckulp··on Hacking an old Kindle to display bus arrival times
awesome work! the original Kindle project definitely has quirks, so we now offer a KOReader option as well. https://github.com/usetrmnl/trmnl-koreader/
ryanckulp··on I built Timeframe, our family e-paper dashboard
we call it Developer Edition, i think this is functionality the same. https://trmnl.com/blog/developer-edition
ryanckulp··on I built Timeframe, our family e-paper dashboard
you can point a higher def Kindle to TMRNL, either our closed source web app or free to an open source server.

ryanckulp··on I built Timeframe, our family e-paper dashboard
what do you think it should be called? for ~$15 optional one time bucks people get 24/7 access to the entire engineering team, me, prioritized feature dev, and can earn monthly payouts from our Creator Fund. we don’t charge a subscription, obviously i’m partial but this model has serves us well. and most of the developer edition fee goes right back to the community via bounties, perks, etc.
ryanckulp··on I built Timeframe, our family e-paper dashboard
you can import ~700 plugins from core to Terminus (Hanami build) or the Laravel build in 1 click. maybe you came on board before that was a reality. we and the community have been rapidly developing multiple self hosted servers with all kinds of features and in different frameworks for comfort. in no marketing materials have we ever claimed that OSS clients were the same as the main web app. in fact that’s why we offer a BYOD license for the web app only. we’ve invested hundreds of thousands into open source so that people can get the TRMNL experience without paying us a penny.
ryanckulp··on I built Timeframe, our family e-paper dashboard
glad to hear this. we made a couple more power savings improvements this week, publishing something on the blog about it ~tmrw.
ryanckulp··on I built Timeframe, our family e-paper dashboard
thanks for the support and i hear you. a few folks pointed their Boox at TRMNL[1], and we’re finally in the smart home arena now with free 5 min refresh rate for Home Assistant. aiming for JIT refresh by summer.

OP's Timeframe looks rad, but yes on the pricy side. check out trmnl .com for smaller / less expensive options and self hosted options. (disclaimer: i'm on the team)
ryanckulp··on Using e-ink tablet as monitor for Linux
we (TRMNL) have a monitor demo, and we also bought a few of the new Modos project, rooting for that creator.

see our demo here: https://www.youtube.com/shorts/qs7JeK11Cxc

ryanckulp··on Using e-ink tablet as monitor for Linux
we (TRMNL) have a working demo, debating what to do with it.

ryanckulp··on Hacking on the ReMarkable 2
cheers, im on the TRMNL team.

looks like reMarkable runs linux so in theory our OSS lib would do the trick: https://github.com/usetrmnl/trmnl-display

which can then point to one of several OSS server clients we offer: https://docs.usetrmnl.com/go/diy/byos#implementations

ryanckulp··on Modos Paper Monitor – Open-hardware e-paper monitor and dev kit
we bought a couple of these at TRMNL for testing purposes ;)
ryanckulp··on Introducing TRMNL X
oh interesting. i suppose we (or you) could be a plugin that parses epub/* formats and thus, a button click on device would fetch the next screen. double-click can already be set to go in reverse. but the full feedback loop takes a few seconds, not instant like an e-reader.
ryanckulp··on Introducing TRMNL X
yes, https://github.com/usetrmnl/trmnl-kindle

ok back up - you claimed we used fake data. obviously you are referring to "John bought X, Y mins ago" notifications. the actual product.

for our homepage counter, this is not customers. this is notification count. with thousands of connected websites, each showing multiple notifications per page load, we quick racked up billions of notifications shown.

running `select count(*) from events` on every landing page load is untenable. instead, every N period we'd check on our avg daily notification count, then update the landing page JS to give users a sense of scale. this number was perpetually under-reporting our actual metrics.

for metrics that actually matter, like signups, customers etc, we created an Open API and read from those metrics on various landing pages: https://fomo.com/open https://docs.fomo.com/reference/fomo-open

and for the core product notifications, "John bought X, Y mins ago" we only allowed data from native integrations. if we saw someone pinging webhooks to us with fake data, we deleted their account. if someone asked for a CSV upload feature, we deleted their account. i cannot say the same for our competitors, who welcomed these use cases with open arms.

bottom line - you're a hater. you don't like Fomo (fine), so you're trying to sabotage the sale of another, completely unrelated product. think about where this bitterness comes from and do better next time.

ryanckulp··on Train and Weather Tracker with Raspberry Pi and E-Ink
thanks for the support! re DIY, we encourage this: https://docs.usetrmnl.com/go/diy/byod
ryanckulp··on Train and Weather Tracker with Raspberry Pi and E-Ink
jumping in to defend myself (thanks f5bot). you are not a serious person.

1. i'm very proud of Fomo. for 6 years we fought against fake data. i said "no" to many lucrative opportunities that were not ethical. our vision was "to given entrepreneurs the credit they deserve," and our mission was "to help consumers make better buying decisions online." your comment is libelous. [1, 2]

2. as of yesterday, all 11 of my courses are free. i've helped over 10,000 people learn to code and learn to sell. [3]

3. on the side i do a bit of pen-testing. i help stop* scammers, and i help non technical folks protect their brand. that's why Bubble added me to their home pages and dozens of cash bounties have been sent my way. [4, 5, 6]

ryanckulp··on Ask HN: What are you working on? (March 2025)
working on TRMNL[1], a hardware startup with a web app companion (Ruby / Rails 8).

this weekend specifically, setting up an in-house assembly area. decided to renovate my barn and be our own fulfillment center.

ryanckulp··on The Unbrickable Pledge
i hear you. only the black case is soft touch, other cases are not. white is currently most popular, ~60% of sales. black 35%, translucent 5%.
ryanckulp··on The Unbrickable Pledge
modding endpoint in FW is no longer required. now built into the wifi captive portal UI: https://github.com/usetrmnl/firmware/pull/66
ryanckulp··on The Unbrickable Pledge
open to it. perhaps granting an escrow service readonly permission to web server box (not DB) would suffice, as then it could all be pulled down, versus closed source on GH?

i'm new to this but we do want to demonstrate sincerity and put our $ where our mouth is.
