Pedals for Ukraine - Ukrainian Army BMP

[Fingolfen]

I enjoy building all the various BMP variants out there (and there are so... many... of them). I'd intended to build a few of the Red Army variants and I'd sourced some diodes, transistors, and LEDs from Ukraine before... things... so I've rechristened the pedal just a bit. I'm using the Tayda board for this build, KT521A diodes, KT3102 transistors, and ex-Soviet Red/Green LEDs (since you can't get a bi-color). Honestly I really love the sound of this one more than my earlier AionFX build - but that one used US diodes and the Green/White dot transistors.     



The 3PDT daughter board is from Frog Pedals and actuates the two LEDs - the red one for when it is in bypass mode, and the green one for active mode. Because these are older Russian / Soviet LEDs, they are dimmer than what most people are used to modernly - especially the green one!



All of the connections to the jacks, as well as the wiring to the LEDs themselves is wrapped in tubular heat shrink to protect the solder joints.



The enclosure is a copy of the EHX-style enclosure that the Tayda boards are designed to go into. The potentiometers are all Alpha, and I'm using new production EHX knobs. The enclosure is hand decaled and painted in "Ukrainian" (definitely not Russian anymore) 4BO green with several coats of flat lacquer to give it a military appearance.



The photo above shows the unit in bypass mode while the one below shows it in active mode.



This is my second build in this configuration. The first one I'm keeping, the second is the one going up for auction. More at the blog: https://steggostudios.blogspot.com/2022/04/ukrainian-army-bmp-sn-002-going-to.html
