I decided to order multiple PCB, to save some shipping cost, and also to test some my ideas too…<\/p>\n\n\n\n

One of them – DC-DC push-pull converter on SN6505 to power up my VFD. I ordered some Epcos N87 rings, done some calculations in Lite-CalcIT, also researched some available info<\/a>, and even found a nice book from Ron Lenk “Practical Design of Power Supplies”. One last thing I need to do before designing an awesome VFD control board – some tests. I haven’t done any custom magnetics before, so I’m very excited.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The resulting PCB is rather small (40x50mm), and has everything I need to test SN6505 and custom magnetics.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n\n\n\n\n

Also to check the footprint for the RCA connectors I’ve made one quick PCB too.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

And finally I ordered parts from DigiKey!<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

I immediately checked all footprints (I wasn’t sure about capacitor dimensions), and ordered PCBs!<\/p>\n\n\n\n

So, JLCPCB, here I come!<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

I received confirmation almost immediately, also I was impressed how many files they are generating for production (kinda I expected, that machines need a lot of files, but still surprisingly a lot).<\/p>\n\n\n\n

And yes, mask colors are free (only +2 days), so I ordered some.<\/p>\n\n\n\n

Also I prepared some very complex device to bend the resistor legs:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Yes, it is very simple, but thankfully I need not so many bendings… Still, I wanted to do them as clean as possible.<\/p>\n\n\n\n

I started to search parts for other parts (selector, VFD controller) and was really shocked about STM32 prices. Just look at this:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

This is really crazy!<\/p>\n\n\n\n

To relax a bit, I hacked Ikea furniture a bit:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Yes! Some Ikea + old kitchen moving bracket, and I can put my Revox inside, but still be able to open the cover! <\/p>\n\n\n\n

Now I impatiently waiting for my shiny PCBs from JLCPCB!<\/p>\n","protected":false},"excerpt":{"rendered":"
