Thanks to everyone who came out to the workshop yesterday! A few people bread boarded some circuits, and a few soldered some prototypes on strip board, after some some debugging we managed to get everything working! Here is an updated…
I ran into this post a few years ago and have thought about this often. This looks similar to the Crowther Prunes and Custard. The First op-amp looks almost like a normal clipping stage. The second one has a…
A King Rat using a dual op-amp. It replaces the JFET output buffer with the spare op-amp stage. Its another schematic from this thread on Freestomboxes.org. This looked like a really smart idea, I had to try it. There is…
I ran into this post on FreeStomboxes.org. Violet Blues, looked interesting. I don’t own a Bluesbreaker, might as well make this one! I designed a PCB in Eagle, designed, an enclosure, manufactured a PCB. I think this year, all boxes…
Today’s workshop at Noisebridge is about the Common Emitter Amplifier. The goal is to build the common emitter circuit on the breadboard and test it out. What is the Common Emitter Amp? Its a single transistor amplifier found in many…
I built this BJFe Honey Bee Overdrive, from the AionFX PCB. I gave it away, and 4 or 5 years later it has come back with a faulty foot switch. Turns out I’m all out of foot switches, except for…
I’m buying parts and Tayda Electronics is no longer cheapest. I’m sure how I feel about this. Shipping and Tariffs on an order I’m putting together are $50! I made a similar cart at StompBoxParts.com and shipping is $17.75 for…
I’d to thank everyone who came to the pedal building event at noisebridge March 28, 2026. Everyone was super friendly and enthusiastic. I scheduled a new event April 11, 2026. Hope to see you all again! https://www.meetup.com/noisebridge/events/314017920/?utm_medium=referral&utm_campaign=share-btn_savedevents_share_modal&utm_source=link&utm_version=v2&member_id=31132902 if you haven’t…
This is a clone of the Univox Super Fuzz. I built a few of these here. This one uses a matched transistor pair: LM394CH. I thought this would enhance the octave effect since matched transistors enhance this effect. Seems like…
I have this bag of NPN Germanium transistors. These are rare and you don’t see them much in pedals. They offer a huge advantage over the typical PNP types found in Fuzz Face’s, you can use a regular power supply!…
This is an updated PCB for Tremshifter. The original idea is Dead Astronaut effects. I built a few his PCBs, but didn’t like the layout and construction, so I designed my own PCB. My first version had some issues, this…
Did another workshop at Noisebridge Nov. 29. The next workshop will be Dec. 13. Join on Meetup. Just a few people showed up, it was a small but dedicated crew! Made some progress on existing projects. Started some new projects.
