For the past few weeks instead of reading the news i have been making a handheld game console. It has a 1.7" display and a 400Mhz CPU. The front is a trackpad. It does not go online. It does one thing (plays Go), and hopefully does that better than anything else that fits in a coin pocket.

This project got me so jazzed on laundry that I actually got the the bottom of my bin for the first time in probably 15 years

Started the process of open-sourcing all of this last night! Still got some TODOs in the repo but it's all going up here:

Weโ€™ll be bringing all of these to Maker Faire Bay Area next weekend! They can be finished as a necklace, fish hook earrings, or lobster claw earrings for hooking onto hoops, your choice. #glowies #alpenglowies #ledjewelry #makerfaire #mfba2025 #makerfairebayarea

Ah huge! Was wondering about something like this just yesterday. (Though Y'all's web editor is killer)

Graphy showing air quality in our nursery for the past 20 hours or so. It's relatively noisy until 7:53 PM and then goes very stable until 6:20ish AM, which is exactly how long my kid was alone and asleep!

Unexpected data leakage: I threw a BME680 in kid's room so we can keep better track of temps as it gets colder. This is derived from the gas sensor. Can you guess when we left our daughter in bed and when we went to go grab her in the morning?

ah yeah I see some too - I think the constraint I left out is that I want digital output but now that I think about it I can probably work around that

I've had very good experiences with the common I2S (INMP441) and now PDM (MP34DT01) MEMS microphone modules, but I am left wondering: are there no unidirectional (or at least, more directional out-of-the-box) small, embeddable mics?

Enttec + Max/MSP is such a classic combo. That's like... how I got into software

Did you know your MacBook has a sensor that knows the exact angle of the screen hinge?

Itโ€™s not exposed as a public API, but I figured out a way to read it and make it sound like an old wooden door.

Where was my invite to the meeting when we decided that it was OK to just put *mid-sentence* cuts in video. I know folks are using auto-editors and this is probably a byproduct of that but dear lord is it distracting. I would much rather hear you say "um" than fucking glitch out on screen

I have absolutely no idea what this is going to do to my server but if you would like your own command line virtual pet, simply run:

ssh -o StrictHostKeyChecking=no -p 2222 tamauser@guydupont.com

I'd be curious to try! But I think audio's gonna give me all the detail I need for now

I do wish you could add on some pay-as-you-go if you happen to hit the ceiling (even if it were $$$/Mb) but I agree - totally reasonable and a great option for makers

Ambient solar is a good idea, might look into that. Unfortunately the building just leaves the lights on 24/7

Yeah I was thinking about this! Do you know if web pushes work on iOS? (assuming that's what everyone in my building has)

I gather these only really work if you can clamp around one conductor, so I'd need to split the power cables!

tracked it down - for a particle account, you get 100MB free per month across all of your devices (max 100), but then it gets shut off. The next tier is $299/mo which is clearly not hobbyist territory so I'd say that's a pretty hard cap!

I bet with a stereo (or 3+ channel) mic setup I could do it. Was thinking about that but this ended up being so simple implementation-wise

Oh I picked that up but that's like half my motivation for doing this lol

If Twilio didn't become prohibitively expensive, it absolutely would. I do want to do notifications of some kind

and yeah I think the economical situation is LoRa with a Pi, but then you still need some kind of relay to push the classifications to the website!

Nice yeah! Part of the reason I chose the xiao is that it also has an IMU built in.

I tried those AC sensors like a year ago but they're more invasive than I thought, they only work well if you only wrap one of the conductors (vs. entire cable)
