Very impatiently waiting for PCBs. Small one and stencil already waiting for packaging. 4-layer is still stuck in production. Already started with programming for this board. Decided to try out FreeRTOS, huh, already facing first misunderstandings… Let’s see, if it’ll improve code overall.

VFD driver ready to be ordered
I hope, this thing is ready (after many iterations and small improvements and also multiple new uploads to JLCPCB)… Designed for FV651G display Used PT6315 driver SN6505 push-pull driver to generate 30Vdc anode voltage and 2.7Vac cathode voltage Some LEDs and buttons 3V3 LDO FRAM Oscillators USB with filter Header for 64 pins Place for …
Phono preamp inside!
Finally, I’ve finished the phono preamp and placed it inside this beautiful box. Sounds great!
AVR-Doper STK500
One of my first devices was AVR-Doper STK500… More photos!
Experimenting with SN6505
Last week I played a lot with SN6505 from TI… So much power in so small SOT23-6. First and foremost, power source for VFD display (30VDC anode voltage, and ~2.5VAC for cathode)… Efficiency at max current 95%! Amazing. Let’s try to get more power!
