Doing my best to keep on saving Raspberry Pis from the dustbin 😊.
This one arrived with 8 green led blinks - well known RAM chip soldering issue.
It takes some time, but mostly reflowing does the trick.
It did this time as well - you can see it from the impedance on one of the RAM IC caps and USB tester - so we have one more happy customer 🙌🏻.

Btw I chose Fluke 117 if anyone is interested 😃.
Mainly because:
1. Price
2. It’s a relatively new model
3. It has NCV (VoltAlert) - will come in handy with future apartment repairs
4. It has Lo-Z and more importantly as it turned out - LCAP mode that allowed me to troubleshoot my guitar pedalboard setup recently.
In general it’s awesome. One thing I hate is the included probes. Swapped those for the proper silicone ones.
Pedalboard adventures continue 😂.
First I made short patch cords to connect pedals. I thought it would be an easy job and it was, but, man, it took hours or boring soldering and even more so - desoldering and disassembling old cables in order to salvage jacks. But I did it and it was already much cleaner.
Next I plan to rewire power underneath the board.

Since it’s #blackouts in #Ukraine again - time to fix a small #UPS that I bought as broken months ago.
Originally it had a cheapest #BMS that got HOT and same level batteries - 8/12 were dead when I got it.
I replaced batteries with proper 3000+ mAh ones wired in 3S4P and a 40A BMS - now it stays stone cold and should power my router for 10-12 hours.
Spot welded it today during blackout and soldered with my #Hakko powered by #Bluetti 😆.
