Today, I received my #RGBtoHDMI for my #Amiga500 and the first thing I did after initial test was installing the audio board.
I had two options, #soldering it to the RGBtoHDMI, floating in the air, or at the back of the #RaspberryPiZero. I decided to try the first. Luckily there was enough clearance underneath to not touch any components. I did bend the legs of the capacitors a bit first.

I designed another PCB... Small preview without revealing what it will be. It'll arrive mid January, though.
They will be manufactured by @aislerhq again, using the 20% December discount for using their #KiCad plugin.
It'll have the option to use an AVR DA compatible #microcontroller or a #tinyAVR one - I added options for both that I have in stock (AVR32DA32 and ATtiny814). Since it won't use man

I'm a bit worried about the temperatures in my #Amiga500.
The CPU is a ST TS68000CP8 and according to the datasheet, the operating temperature range is 0 to 70°C. After an hour of activity, it is almost 80°C...
The Denise (OCS) has same operating range and stays under 60°C, so inside the range.
The fat Agnus (ECS 1MB) almost reaches 60°C, but I couldn't find a datasheet, yet. I suppose it's fine,

A few impressions of the #repair of my #Apple #PowerBook100 with lots of leaky caps. I had to open the HDD, too, to free the heads that were stuck in parking position. But now it boots again. I have to take a closer look at the LCD, though, the contrast is way too low and the potentiometer has no effect. Maybe the LA5316 is broken, or the leakage spread further than I noticed. I had to clean the s

Finally found some time to bring my #NeoPixel Heart PCBs into a usable state and add some documentation. The #sourcecode is hosted on @Codeberg at https://codeberg.org/rommudoh/NoisyMcHeart and works for both variants (big and small).

Yes, it's a great video!
Inspired by my last #WS2812B #PCB, I decided to do a smaller version and try to add a USB C connector. I'm very pleased how it turned out. The LEDs are not as close to each other as last time, but I still used my hot plate to solder them. …
Here are the boards! I soldered a first one by hand, but the #WS2812B #LEDs are very close to each other. So some have burn marks. Hot air is no option, it would burn them up. So, I bought a hot plate and tried again. It's so much faster a…
Bad luck, the PCB shipment got lost. But @aislerhq was so kind to produce and ship them a second time. Thanks a lot!
Since it'll take some time for the PCBs to arrive, I decided to make a #prototype on #perfboard. It works fine, and I can test my programs using it. Turns out an #ATtiny814 is good enough for the task.
The #WS2812B #SMD #LEDs are very brig…
