Precisely 2 weeks after order, boards are on my table. Quality, as always, very impressive. Fun fact, 30 small boards cost less than 10 🙂 Stencil, solder paste, some sand and frying pan – and first PCB is ready! After correcting some small issues I noted, what I soldered the wrong microcontroller on! Hot air, …

PCB in production
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.
Phono preamp inside!
Finally, I’ve finished the phono preamp and placed it inside this beautiful box. Sounds great!
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!
PCBs are here!
Here it is, already with all components: For detailed photos from all PCBs and some from old good Fluke, just:
PCB on the way
This week JLCPCB produced my PCBs, and they are on the way to me. The total time from submitting files to “package shipped” was ~5 days. Because I ordered 3 different PCBs (also 3 different colors), I was interested, how long it takes to produce each color… So, I’ve made a graph, where you can …
