Show Your Pedal Builds

Amazon man dropped off a few accessories to assist with my prototyping.

Just a few bits. :grin

Do you have anything which can measure the hfe of those transistors? I'd you don't then grab one of these.

You'll find it under different brand names on amazon but the model number is T7 or TC7. It'll measure hfe and tell you the pinout of your transistors, if you get some germanium it will also measure the leakage. They're less than £20 in the UK so should be similar in $.

If you want something a bit higher up the food chain that's better built the Peak Atlas Dca55 or DCA75 are the ones to get. The cheapo one listed above though will be fine if you're only going to build a few pedals.

Yes, I included the tester below as part of my "modern retooling" purchase a few days ago.

FNIRSI LCR-P1 Transistor Tester, Mosfet Transistor Capacitor Tester, SMD Electronic Component Tester, Diode Triode Zener Diode Resistance Inductance Battery Test LCR Meter MOS PNP NPN ESR Meter

I believe it cost $25 (after bundle discount). It is supposed to arrive today along with my new MM/oscilloscope and variable power supplies.

Sorry I missed that. I've not used that one but they all run the same software. It looks a lot less like a fisher price toy than the one I listed though :rofl
 
I have another shelf with multiple Audrino boards, LCD displays, small OLED displays, a 2.8" TFT touchscreen, a handful of 16 channel I/O multiplexer boards, some micro servo motors, and a "starter pack" (pictured below) that includes 37 sensor modules for Audino projects.

Let the fun begin! :rofl

See now this kind of thing interests me because I know absolutely nothing about it. I'm looking forward to seeing what you come up with.

I keep meaning to buy an oscilloscope. There's a few pedals which I tune by ear which would be a lot quicker with an oscilloscope instead.

I paid $90 for the o-scope/DMM/signal generator combo. It's not the greatest scope, but it's more than adequate for my needs.

It has 2 channels with a bandwidth of 50 MHz and a 250 Msa/s sample rate, which is more than adequate for building pedals and Arduino projects.

The UI is a bit clunky, but the feature set is decent considering the price point.

Unfortunately, the waveform display lacks a "rolling" update. On bigger timebases, it loads the waveforms more slowly left to right, writing over the previous ones, rather than having them roll on screen from right to left,.

Using the DMM is also clunky, especially since I'm used to selecting a measurement function by twisting a large dial instead of deep diving into multiple levels of menus using buttons. This should be mitigated as I become more familiar with the device.

It's so tiny, about the size of a deck of cards. Same with the 30V power supply below which is just as small.

I've decided I need a dedicated workspace for my pedal project pursuits. I work from home, and there is not enough room in my office for a new "permanent" project area.

I have a great workbench and tool area in my garage, but it's not air conditioned, and this is Florida.

Since my newest desk is over 20 years old and 100% dedicated to my day job, I felt it was time for some modern ergonomics and convenience. A little research later, and I am now waiting for an Autonomous SmartDesk 5 Pro standing desk to ship on August 11.

One step closer. While waiting to dress out my pedal workspace, I'll start assembly of the utility boards I ordered from Seth @ HA.
