Something New Every Day

  • Coding
    I started writing my own firmware, from scratch, for the Malenki. I want to use them with a HK-T6A V2 transmitter, which uses the AFHDS protocol not the AFHDS 2A protocol the Malenki uses. Despite the similar name, they are entirely not compatible at the firmware level. (But, fortunately, use the same radio hardware.) It… Read more: Coding
  • Burgers
    For the first time in months I fired up the grill today. Yes, it’s still unseasonably cold and there is still a lot of snow. The burgers were good.
  • Wine
    I bottled a carboy of wine yesterday. I buy a few 5 gallon buckets of fresh juice each fall. Last fall’s juice is ready to bottle now. I washed my bottles well months ago, but still gave them a quick rinse. and spray some metabisulphite in to sanitize. I racked the wine to a clean… Read more: Wine
  • Malenki Nano-Plus
    I have a Malenki Nano-plus PCB. I have a Serial UPDI programmer. I have successfully flashed Arduino “Blink” onto my Nano-plus. The final step is flashing the actual Nano-plus firmware onto the Nano-plus. I used a docker container for the dev environment. Then I copied prog.py from my Arduino install. (actually the megaTinyCore files) The… Read more: Malenki Nano-Plus
  • Serial UPDI
    I built a Serial UPDI programmer. (For a certain definition of “built”) These are pretty simple. A diode goes between Tx and Rx on a CH340 module. Then a wire from Rx goes to the device being programmed. I’m also using a SOICbite (slightly modified SOP8 test clip) as a programming clip. So, I used… Read more: Serial UPDI
