Erica Synths .EDU Sequencer - Building and Demo 

I just got the whole kit, including the case, from Thonk. 😀

I learned about soldering from the top from Ray Wilson, and he was NASA certified in soldering! In modern professionally made PCBs the holes are metal plated all the way through. So no matter which side you solder from, it'll make it to the other side. For low profile component that leave the top hole uncovered, it's just faster and easier to solder from the top. You only have to turn the board over once when you're done, touch up any trouble spots and trim the leads. No having to spread the resistor legs out so they won't fall, no sticking the iron tip into a forest of leads. And it just makes sense to continue in order of height, so you can still rest the PCB on the table to solder for as long as possible, before the components start getting taller. Love from Mexico!

everybody makes 8 step sequencers! Only Don Buchla and Moritz Klein chose 5 :)

@@QuincasMoreira well, who am I to judge the *big* boys? 😁

@@QuincasMoreira I do have a new sequencer up my sleeve and although it’s not going to be for Eurorack, I think you’ll be impressed with the unique functionality. 🙏🏻

Hi! Check the IC orientation, and do a magnifier inspection for shorts anywhere on the board… sniff around to find where the smoke came from

@@QuincasMoreira IC are fine, R13 (10Ohm “fuse“) was blown up. Resoldered power socket and replaced R13… 2nd round of smoke. Will spend time with the magnifier as next step

@@rustychuan there’s a short somewhere if the fuse is blowing….

@@QuincasMoreira thanks- I will start searching for the short and reflow my solder joints….

nothing! LOL. Just measured: 17 mA on +12v and 6mA on the -12 rail!

@@QuincasMoreira Thanks yeah ES replied as well, I guess by their numbers it should be 16 mA / 6 mA, so sounds good. Going to see what happens when I chain 8 of these together with some ADDAC switches :D

@@nelen_co cool idea!

@@QuincasMoreira Just built the first one tonight. Hardest part was getting those chips in at the very end.

Thanks!
