All along I knew I wanted to figure out sound for Dodo because a game system just wouldn't be right without it. I have been going back and forth with lots of different approaches in my mind. Dedicated sound generation chips that mixed both digital and...
Wrote a very basic command interface with three commands:W - Write the EEPROMR - Read the EEPROMB - Bounce an LED across the RPP-UIO-16 cardThe result looks like this:Write to the EEPROM Read from the EEPROM 0000 00 01 02 03 04 05 06 07 08 09 0a 0b 0c...
1. Toolchain not found After stepping away few days far from my PC for family reason, I resumed my activities on the Tsykuyomi project.So I started by reading the https://github.com/WHhkwong/SIPI_Bear_playback code and looking for a SNC7001A Toolchain/SDK...
The STM32 board was just a hair bigger than the PIC, but the biggest pieces are still the power switch, channel button, & battery. The plan is just to print an L enclosure which scotch tapes around the hot shoe & sticks up. The antenna will...
After a fresh installation of Debian on my Beaglebone Black I was greeted with a console interface that had all the essential tools already installed. It's a development platform after all. They provide everything for I2C devices as well. I had a 24C02...
With the wiring complete I wrote a small program in Python to test the lights, buttons, and switches on the front panel. To be clear this is NOT the KENBAK-2/5 emulator running a program (yet). As it turns out I did have to replace one of the LEDs...
I've been hinted at this 43 years old project from Elektor:https://archive.org/stream/Computer74/computer-74It's exciting that this idea has been in the air for so long, and yet we don't see it widely spread...

Back to the workshop for the revenge of the return of the son of the Vintage Ring Oscillator ! This time with a new ally : the ceramic capacitor ! TL;DR : it's 60% faster ! But the V/F curve might look different from @Tim 's experiments... As usual,...

Well, I did it. I ordered my first custom circuit boards. I laid out a prototyping board with an ISA bus card edge, sent it to dirtypcbs, and after a month of impatiently checking the mailbox, they arrived. I ended up with eleven boards. After I've built...
Upkie communicates with a regular PS4 controller. While this is not a key robotic feature, it is both cool (especially with kids 😃) and convenient to control the robot via Bluetooth. Before trying it out I was concerned about potential lags,...
