I've got 241 stars on this! Haha. So here's another bit of 50/60hz weirdness. Regional microwaves. This is a sticker on the top of a microwave in Yonago city, Tottori Prefecture.

The white on black text says this is 60hz only. The map on the bottom shows the divide with a few cites being pointed out. There's also text saying that Okinawa is 60hz.

If you happen to be in the #Houston Texas area and you are into diy #electronics, #robotics, #radio, repair, etc, I highly recommend you check out Electronic Parts Outlet, aka, EPO. I’ve been shopping there for years and I’m always finding stuff. They’re locally owned, not a chain, so you’d be supporting local as well.

Their website is a bit fragile so here’s the address:

3753 Fondren Rd B, Houston, TX 77063

What's the simplest way to visually convey text, aside from morse code blinking?

I'm doing some experiments in #pygame to work out just how low-res I can go with scrolling text and still be legible.

These three animations show text scrolling across a simulated display with 1px, 2px and 3px width. I'm using a 5x3 pixel font from adafruit.

I think 2px is *barely* readable.

Imgur link because I can't upload the WEBMs to my masto instance for some reason.

Anyone have a source link describing what the CPU in an NTS LC82046D custom chip is? I've seen some sources saying it's a V20 and others that it's a Z80 - anyone know the right answer? It's the main chip in a Tandy DreamWriter 200 if that helps... #RetroComputing #Electronics @retrocomputing

My first 4 layer #PCB. It's an #USB #audio device with a #PCM2706 and a mono #amplifier for my #NeXT #SoundBox mini. It is not finished yet. There are more circuit testing to do.

Ich wollte schon immer einen 12-Ton-Musik-Automaten haben und heute habe ich ihn gebaut. Dann mit Midi Ausgabe an einen Modularsynthesizer angeschlossen und ein paar Effektgeräten dahinter.

I was reminded how slow the internet was as I stress tested a UART circuit by sending files over it. Kind of amazing that we used to browse the internet at <1 Mbps reasonably fine because it would be unbearable on the modern web

Hey, I'm Sarah but I also go by FaeMittens online, and this is my #introduction. ☺️

I'm a queer #transgender woman in my early 30's currently living in northern Lutruwita/Tasmania and hoping to make my way over to Naarm/Melbourne with my awesome (also #trans) girlfriend soon.

I write code to command #electronics to do things for a living, mostly on bare metal ARM in C but occasionally running Linux in C, C++, or Python; but I'm currently out of work and working on my mental health and transition (burnout sucks).

#Photography is how I express myself but I've also considered dabbling in #gamedev, if I could just stick to a single idea. 😅 I also love to play games, read, listen to music of many different genres, and learn; I'm nerdy as hell and enjoy diving into different technical, scientific, and math topics when my #adhd sparks a focus. Sometimes I also get into a bit of ancient and classical history.

Anarcho-communist and anti-capitalist.

I use arch btw.

Der Handy-Akku macht schlapp, das Gerät hält bei normaler Nutzung noch nicht mal bis zum Nachmittag. Ein Akku-Tausch ist mit etwas Feingefühl und dem richtigen Werkzeug eine machbare Sache. Hierzu gibt es super Schritt-für-Schritt Anleitungen online (@iFixit). Nach dem Tausch hält der Akku bedeutend länger und die Lebensdauer des Gerätes wurde damit signifikant erhöht!

The cell phone battery is dying, the device doesn't even last until the afternoon with normal use. Replacing the battery is doable with a little skill and the right tools. There are great step-by-step instructions online. After the replacement, the battery lasts much longer again and the lifespan of the device has been significantly increased!

So one thing led to another and I am back to being the maintainer of libopencm3. Thanks karlp for all the years of dedication. I will do my best to take care of locm3 well. I will work to address the PR backlog and do a bunch of janitorial tasks. Please be patient :) #opensource #embedded #electronics libopencm3.org
