MCU, shift registers, LFO, metal oscillators, switching circuitry, mode cv circuitry, noise generator, VCO1 + VCO2, voltage supplies tested and passed!
The testing procedure at this point is hand assembly of two units, verifying everything works as intended before going into production.
Still on track for late next week pre-order run!
Sunday tests start at the trigger input circuitry, trigger force circuitry, and the overdrive. Hopefully more including the envelopes, sample & hold, and the VCF and VCA.
The v1.4 PCBs are here, and so far all testing has been succesful.
Today was firmware revision day. The purpose of revising the firmware was matching colours and luminance of RGB leds and the single regular led.
Over the weekend the remaining circuitry will be tested.
Manufacturing of actual units should begin late next week.
Test and verification is what happens today (YMMV) as soon as v1.4 of the Drumbo printed circuit boards have arrived, and in the following order:
- Regulated voltage supplies
- VCO1 + VCO2 + Noise circuitry
- MCU circuitry + firmware test.
While we're all waiting to hear the first sounds of the production version of Drumbo... here's something else. An unboxing video. ASMR FTW!
Panels arrived today!
They look great!
Next update... sooner than you'd think! ;)
