The EAGLE Tutorial Continues

Thanks to everyone who bought boards over the weekend! Today starts the next chapter in the Eagle Tutorial series on YouTube: PCB creation. Go check it out!

EAGLE Tutorial

 Finally gotten around to creating this tutorial! There's a lot, so it will be released in several videos over the next couple weeks, but the first two are live on YouTube now. So if you're interested in learning Eagle CAD to layout your own PCBs, either for etching, milling or fabrication, go check it out!

Spaceman Atlas III

Hope everyone's staying safe and healthy. Today's layout is a unique preamp booster from Spaceman Effects, the Atlas III. It uses some FETs I'd never heard of in conjunction with a couple low gain silicon BJTs (use something in the 175-225 hFE range). The switch controls the phase of your signal (it's internal in the original). Schematic can be found here for reference.

Also, I updated the Make a Difference page on the website to include a few funds working to help in the aftermath of the Beruit explosion. It's killed well over 150 people, injured 6000 and left over 300,000 people homeless. If you can, do some good, offer some home and help out some people who are really hurting.

Mad Professor Simble

This is been traced for a few weeks now over on FSB and I've meant to lay it out since then, but just now getting around to it. If you don't know, it's an amp-in-a-box type trying to emulate a Dumble amp. Apparently it sounds very good with smaller amps. Should fit nicely in a 1590B with board mounted pots as per usual.

Caline Purple Smoke

Got a little booster circuit that should go together pretty easily. It's pretty much an Electra without clipping diodes and a large value resistor between base and collector (similar to the EQD Arrows). Easy fit in a 1590B or even a 1590G (probably). Schematic on FSB.

AMZ Mini Booster SMD

What's everyone think of SMD? It seems more and more boutique builds are going that route, and with more parts only be available in SMD form, I wonder how long before it'll be hard to get quality parts in through-hole packages. All that to say, here's a simple etch-able SMD layout of the AMZ Mini Booster. I've left the power polarity diode and power filter cap (folded onto its side) as through-hole as getting the right packages can sometimes be a royal PITA. All the caps and resistors are 0805 size and note that C3 is a non-polarized cap. Should fit easily into a 1590A.
