  • Paul Falstad’s Circuit Sim

    If you are into making things with electronics you probably need to test them out from time to time. Paul Falstad has a really great on line circuit simulation app. It’s a Java applet. Try it out here:  http://falstad.com/circuit/ Here’s a picture of a Fuzz Face I mocked up. Notice the scope at the bottom.…

  • Webcor amp

    I traded a Fuzz Factory Clone for what looks like an old PA that’s been modified to work as a guitar amp. The Webcor has two speaker connected with what looks like a giant oil and paper capacitor. One speaker looks to be about 6 inches across and the other is about 4 inches. There…

  • Stompbox Cookbook PCB layouts are BACKWARDS!

    I just started building up a project and I realized the PCB layout I printed from the Stompbox Cookbook is backwards! Beware if you plan to build a project from any of these layouts. I think I can save my build by either bending the IC pins over so the chips are upside down, or…

  • FSH-1 PCB

    This will be the fourth time I try to build one of these. I made a PCB for the original using the layout from GGG. I never finished this. Then I built and finished a second using the layout from UStomp.com. I couldn’t get this to work. I forget what the problems were, it was…

  • Batteries or no batteries?

    I’ve run into a few project lately, Casualty 4 and Sunking, that fit in a B sized box, but leave no room for a battery. This has me rethinking the battery as a power source. To be honest I use batteries almost exclusively. I rarely use a power supply. The reason, I don’t own a…

  • Sunking

    Not sure if this is Sunking or Sun King. Either way it’s clone of the Klon Centaur. That apparently fits into a B sized box. Hats off to MadBean for making that happen. I way have to give this one a try. Here’s a link: http://www.freestompboxes.org/viewtopic.php?f=14&t=6392&start=40

  • Some PCBs

    Here’s the current projects. Two Echo Base and two Casualty 4 Phaser shifters.

  • Old School Layouts

    I found these old school layouts by Andy. These look like fun to build the layouts just scream mojo. I think I will have to etch a few of these up and build them with carbon comp resistors and ceramic caps! Andy aka “Dragonfly” posted like mad on the DIYStompbox forum for several years and…

  • Art of the Stompbox

    Looks like one of my Ugly Face’s made it into the “Art of the Stompbox” exhibit at the Museum of Making Music in San Diego. http://www.flickr.com/photos/museumofmakingmusic/page3/ http://www.museumofmakingmusic.org/index.php?option=com_content&task=view&id=282&Itemid=41

  • Electronics Demonstrations

    Wow, you must take a look at this site. These are the most amazing applets. http://www.falstad.com/circuit/e-index.html

  • DIY Electronics Swap Meet 2010

    Bay Area DIYer’s should make it to the DIY Swap meet on Feb 21 at 924 Gilman St in Berkley CA. For more info: http://www.euthymia.org/ The first three were a great time lot’s people with lot’s of stuff. Anyone from the should meet up with me. I’ll try and wear my DIY Stompboxes t-shirt.

  • What am I missing?

    Assume there’s your favorite booster at the input, what is D2 doing? This is the most common clipping arrangement that I have seen. It seems that D2 does nothing. If the boost at the input is running off 9V then the you should have a single that is centered on 4.5V going past the two…
