My name is Andrej and I’m a DIY enthusiast! This blog will be a place for my projects, mainly concerning guitar effects, amps, wiring, effect switching and embedded systems programming of all kinds.
This has been a hobby of mine for a while and I thank the great communities of freestompboxes and AVR Freaks (I’m just a lurker there) for inspiration and help. It has been my wish for a while to turn this hobby into a job, but I’ve decided to stay faithful to the community and open-source.
I announce several projects:
- Gonich MkII – an Arduino-based, digitally controlled analog (latching relay) floor effect switcher with MIDI In and Out, footswitches, variable pedal count, preset banks and hands-free editing
- Blue Waffle – an 8-bit waveshaper/bitcrusher with added bitwise manipulation and 10 user presets – in guitar pedal form. It sounds eww and is a WMD Geiger Counter work-a-like with more features.
- Unnamed digital delay chip project – a code project for a cheap DSP chip (<10eur), which turns it into a 1sec (1ms intervals) digital delay chip with tap tempo, hold, and modulation. There will be no external clock – all you’ll need is a mix/feedback circuit, a delay knob and a tap/hold momentary footswitch. Modulation pots optional. I hope it will be a canvas for the DIY community, replacing PT2399 in various analog/tape delay simulations and similar circuits. I also plan to license it to boutique pedal builders.
My ultimate goal is to do a series of crowd-funding projects for my commercial designs, where various amounts of money will fund products with various levels of completeness (programmed chips, PCBs with programmed chips, partial kits, full kits, and finished products). However, every time my crowd-funding projects go through, I’ll release either the whole source/schematic/PCB or a slightly less featured work-a-like here (replacing microcontrollers with Arduino boards, to make it easier to program by the inexperienced members of the community and to give my commercial products a fighting chance). These projects will be free for non-commercial, personal use.
Your feedback means a lot to me, so feel free to comment! I’ll make a few polls in the future, too, when this site receives enough followers.
