Pedal workshop Noisebridge #3
Thanks to everyone who came to the last pedal building workshop at Noisebridge. I was impressed with the enthusiasm! We demoed some pedals talked about populating the PCB and identifying the correct parts and placing them in the correct locations on the PCB and soldering. The next workshop is scheduled for Saturday, March 4th, 1 […]
Here is a version of RunOffGrooves 22/7 using the 4069. The original circuit uses the 4049 Hex inverter. The 4049 is a 16 pin dip with 6 inverters. Here is the 4049UBE data sheet. You can see it has 16 pins with 6 inverters. There is a power Vdd pin 1 and ground Vss pin […]
Stompbox Studies – Class 1
Want to build your own effects pedals? A good place to start is understanding how transistors work. Transistors are those three-legged devices seen populating many stompbox circuits. Transistors are a core building block in electronics. Integrated circuits, like op-amps, are made up of many transistors! Transistors are used in all of the circuits you’ve probably […]
Parentheses Fuzz #3 EQD Life Clone
I got three boards from Pedal PCB. This is a pretty good project. It cost a bit more than the usual 1590B sized projects. It works well and sounds great. I’m keeping one and selling the other two on Reverb as a way to support my hobby. Check this out on my Reverb shop. Or […]
Harvesting parts from these old PCBs. I had this need for a A100K pot and Christmas 🎄 has holding up the deliver from Tayda Electronics. So I started digging through my bin of old projects that never made it into a box 📦. I didn’t my ideal A100K pot, it would have been 16mm with […]
Stomp box enclosures and shielding
I was trying to up the quality of my builds and thought about shielding and noise. Did a little research on the interwebs and came up with a few tips. First a little background. High gain circuits often run series of gain stages in series. If you have an input stage of x10 followed by […]
UBE Screamer PCB v1.1
This is the second version of the UBE Screamer board. This version fixes a mistake with the reverse polarity diode. I’m calling this ready for public consumption and will add it to the OSH Park projects pages soon. The enclosure is grounded through the jacks. The bottom cover though doesn’t make an electrical connection to […]
Vulcan pcb built up. This is version 2.
Milling a PCB
effectpedal: Making PCBs on the Othermill. Designed in Eagle. I played with the trace size. The default traces in the bantamtools DRC is really small. The 8mil traces are easily damaged.

Vulcan by Joe Davisson
This is Joe Davisson’s Vulcan overdrive. Starting with a prototype board made at home with the Othermill, then turned this into a board from OSHPARK. Boxed up and is working well. This is an interesting overdrive with a couple unique circuit features.
Box of Rock clone
Box of Rock bootleg in process. Milling the box on the Bantamtools Othermill.
