Switchcraft Panel Mount Drill Hole
I always seem to forget this.. time to note it so I can find it easily when I forget again.
Switchcraft Panel Mount holes are 7/8″ round.
Now that I wrote it down I should always remember… right?

Since I recently made a bunch of Electric Druid’s TAPLFO chips, I have been asked how I went about programming them. I decided to make a tutorial so others can program their own PICs.
In my case, getting the PicKit2 clone (CanaKit) to work on my Macbook Pro was a challenge. So I decided to share my process to help other out.
I have quite a few builds in the works but none that are complete. I hit a wall with 2 builds since I had problems with my builds and need to troubleshoot. I wanted to list out a few builds I have finished and need to box up in the next few weeks to help me prioritize them.
To be boxed:
Twin Peaks Tap Tempo Harmonic Tremolo – This is Drolo’s taptempo (TAPLFO based) tremolo pedal. I love this thing and it has been siting on my test rig way to long now. I need to get this boxed up ASAP and attached to my board. More info at Madbean or on his blog.
8-Ball – This is Madbean’s modded Blues Breaker and it sounds great. I had a modded BB I did on a PCB from JMK and never really got attached to it but the 8-ball may have brought some new life in the Blues Breaker. You can grab a PCB here.
Mudbunny – I built this Madbean Big Muff variant to Russian Green specs and love the sound of it but never seem to remember to box it up. I used some unmarked NOS button top transistors that just sound great in this thing. You can get a PCB here.
Ultra Stoner – I have built 2 of these and love both of them. I am thinking of doing a 2 in 1 with them and make one a lower gain into a full gain one… hmm… You can get a PCB here.
Machette – Ugly Face with LFO, this is a crazy effect and deserves a crazy enclosure. I am working on a few etching ideas for this. You can grab a PCB from here.
Need to finish populating:
There are more that could be on this list but this is all I really have on my mind at the moment.
I was looking at a few transistor sources for a simple Fuzz Face layout I built and came across a nice post over at DIYSB by DragonFly

also…for a nice “all-arounder”, 2n3903’s work well in both q1 AND q2 ….
Looking in to others also but I wanted to get this down to archive it.
Work has been killing me the last 2 weeks and I have had no time/desire to work on any pedals. I have been playing a lot more this week and making some decisions on new hardware and what will be kept and sold.
I have ordered quite a few PCBs from various people online as they come in stock and available. I am also working on my first double sided PCB to submit to OSH Park.
Here are the new PCBs I have in had at the moment waiting to be built:
I wanted to share my current process for etching a PCB from scratch. Here is a list of supplies I used in this tutorial.
Items I needed:
I have been asked by a few what things I have at my workbench and I decided to make a page that will be a list of tools and “what nots” that reside on or around my workbench. Most of the stuff I have is used with every project one way or another. There are necessities and also some “nice to have” tools that I have collected over time. I made the mistake when I got started by spending 80% of my start-up money on parts and 20% on tools. If I were to do it all over I would have flipped that percentage. This does not mean that you need to buy all Swiss made hand tools or a $500 soldering station. If you want to get top of the line tools don’t let me stop you, I just found that Harbor Freight $3.99 flush cutters will not hold up as well as a $13.00 Xcelite pair. I am now replacing half of my hand tools with a little better built ones since in a year’s time I have dulled or broke my others.
Take a look at the page here or click on Workbench from the menu at the top of the page.
Flush Cutters: From cutting leads off the bottom of PCBs to cutting hookup wire these are one of my most used tools on the bench. I had a cheap Harbor Freight pair I had that dulled and broke with in a month. I now own a pair of Xcelite that I picked up from Frys and I love them.
Long Nosed Pliers: I mainly use these to hold parts or to help feef wire in a enclosure. The Xcelite pair I got are still in great shape for being a year old and have a good amount of use.
Precision Screw Driver Set: I own a Boxer Precision Bit Set that I picked up at Frys but they are sold on Amazon and Newegg also. There seems to allways be a need for precision screwdrivers. From tighting the screw on a knob to opening an enclosure.
Wire Strippers: Nothing special about mine, they just work. Just find a pair that works for you and get to stripping.. wait..what?
Automatic Center Punch: The quickest solution for punching your enclosures before you take it over to the drill press. Best $1.99 I ever spent.
Soldering Station (Variable Temperature): This is where I spent some time doing some research and wanted to get the best bang for my buck. Now, I did buy this about 5 years ago and did not have pedal building on the mind. I used it mainly for modding game consoles and small DIY gaming projects. I ended up getting a Weller WESD51 and have loved every minute I use it.
Brass Sponge: Got to keep that soldering iron’s tip clean. This can be overlooked and its a cheap buy. Get one!
Desoldering Pump: You will need to remove components off a PCB at some point and this is the best way to do it.
Digital Multimeter: When I was looking for a new DMM I wanted just something basic that will meet my needs and unfortunately I was unable to afford a Fluke at this point so I wanted something that would be as/as close as accurate. I ended up picking up a Sinometer MS8229 for $40 and I love it. It has WAY more bells and whistles than I need but it will do the job just fine.
Digital Oscilloscope: Picked up a Atten ADS1062CAL Digital Oscilloscope for a very good price and I am still learning to use it properly. It seems like it will be a tool that will payoff with in time.
6″ Digital Calipers: I am the worst at measuring things, let alone very small things. These were a necessity for me. Maybe you are the same.
Step Drill Bit Set: All hail the best thing since sliced bread or some other kind of awesome invention we relay on. I picked up a basic set of three from Sears and a cheat sheet that says for an example: 1/4 inch jack in 3 steps down on the drill bit. With this cheat sheet I can make all my needed holes very quickly. Nothing to fancy.
Drill Bit Set: Basic set just for odds and ends. I picked up some at Sears that work with the Speed-Lok system just for convenience.
CNC Drill Bits (For PCBs): Want to etch your own PCBs? If you answered “yes” then you will need some of these. I picked up a set of the most used from eBay for $12.
Small Drill Press: This was one of the tools that I put off for so long and I wish I would not have. I was using a hand drill to drill all holes on an enclosure and it was a crap shoot if they came out properly. I finally found a small bench-top drill press that worked for me and was very reasonably priced. I got the Craftsman 10” Drill Press and never looked back.
Craftsman Speed-Lok: Its great to be able to swap a drill bit or a step drill bit instantly without the need for a drill chuck. Makes life a little better at the bench. I am sure there are other brands of this product but this is what I went with.
Glue Gun: I use this mainly for LED bezels and sometimes for wire management.
Toaster Oven: I like to make toast and heat up pizza at the bench… I kid, i kid. This is another thing I put off getting and now I see it as an essential part of my bench. I can paint an enclosure and stick it in the toaster over for 15 minutes at 150 degrees and let it cool for another 15 minutes and you are ready to assemble your pedal. Its great for quick builds and for drying in between paint layers. I ended up picking up one at a thrift store for $10 and it works great. I do recommend that if you do buy a used one, use a oven thermometer to make sure it gets the desired temp and not trust the gauges.
iPad/iPhone Charger: My iPad/iPhone seems to live on my bench when I am working on a project. I hate when the batteries die when working on a project.
iPad: I use this mainly for Google Drive to access all my build documents and for streaming music at the workbench. As of late, I found that Netflix and Hulu is great also at the bench to help calm things down.
Portable Bluetooth Speakers: Not a must but it sure makes the music or TV/Movies sound better from the iPad.
Here is my first attempt at combining a couple PCBs and tying in the power together. There will most likely be some changes. I am etching this board tonight to mess with and see how the shared power works out.
Each circuit individually has been verified by its designer and DIY communities.
It is a combination of 3 PCBs made by other people. I do not take any credit for making these designs individually, I just combined them for a neat/clean build.
What circuits are they?
Whats left?
I have an order of some parts I am waiting for but I am thinking of building this in a 1590BB so its not to large and takes up to much space on the bench.
I have been rolling the idea around about building a new test rig and I have been reading up as much as possible on the subject. I have come to the conclusion I need to list out what I expect from it. So lets try this.
Most of this will be common knowledge but I wanted to get the thought process out.
Testing:
Troubleshooting:
Here is what I’m thinking of using so far:
Madbean’s Charge Pump “RoadRage”
R.G. Keen’s Quick and Less Dirty Oscillator
