Title: My first designs: JANUS, GAIUS, and CYCLOPS — Video added July 16
Post by: tatou on June 22, 2016, 06:27:42 PM
After a few kits and builds from others' PCBs, I decided to start learning EAGLE and hacking together my own projects a few months back. This forum has been a great resource for learning my way around, and special thanks to jkokura, m-Kresol, and markeprice and others for answering my EAGLE and OSHPark questions!!

Last weekend I finally finished my first couple of builds on this journey. They're all are simple circuits based on DIY classics plus some extra mods, designed for 1590a boxes.

Images below link to my project docs, which I'm hosting on Github (https://github.com/burrsettles/pedals). EAGLE files are included, if you want to fab your own for personal use. I also have some extra boards from my OSH Park order, in case anyone's interested in a buy/trade! :)

JANUS overdrive
A mashup of the Dan Armstrong Blue Clipper, MXR Dist+, and DOD 250 with switchable clipping diodes.

GAIUS ringer
Dan Armstrong Green Ringer with a "NULL" pot that varies the intensity of the effect.

CYCLOPS fuzz
This is a snarly one-knob beast. Based on the runoffgroove 22/7 (CMOS attempt at the EHX Big Muff), but with the tone stack stripped out for a flat frequency response, and the sustain pot brought inside as a trimmer. Just a volume knob!

Cool! Have any way to do sound clips?

Thanks! I'll see if I can make any vids and/or audio clips this weekend. That's an obvious omission...

The ringer is more of a weirdo toy, but the two dirt boxes sound great and I've been using them with my band. Our bass player even commissioned me to build him a JANUS. :)

Great Job!  looks pretty clean!  Hey, I am about to release my Frog Tube Preamp DIY PCB within the next week or so.  Look me up at facebook frogpedals, my website at frogpedals.com or the Madbean forum link:  http://www.madbeanpedals.com/forum/index.php?topic=22173.msg227115#msg227115

Great job! It's always so satisfying to design your own boards and find out that they work!

Awesome job!
I still have yet to attempt any board layouts. Must be a pretty good feeling of accomplishment to get some done and working. And might I say, ballsy move going for 1590A builds.
I'm sure once I try my hand at PCB design, the smallest thing I'd be looking to work with would be a 1590B!
Congrats on your killer little boxes!

Thanks everyone!!

Since — nearly a month ago — chordball asked for soundclips, I got around to making a video tonight for the JANUS overdrive and posted it to YouTube (https://www.youtube.com/watch?v=GEBxokpxBRk).



I look forward to learning more and making more designs — in particular for the 1590a. I find it to be a neat and intuitive form factor. So far I've been working on a tremolo, chorus, booster, and envelope filter...
