DIY Eurorack: Progress (So Far)
Here’s the current progress of my DIY Eurorack modular synthesizer. I’ll update this post everytime I add a module or significant change.
Current Setup

Details
| Module | HP* | +12V mA | -12V mA | +5V mA |
|---|---|---|---|---|
| Passive Multiple | 3 | 0 | 0 | 0 |
| VCF | 6 | 5 | 5 | 0 |
| VCO | 7 | 7.5 | 7.5 | 1.1 |
| VCA | 7 | 10 | 10 | 0 |
| LFO | 7 | 4 | 4 | 0 |
| Passive Attenuator | 4 | 0 | 0 | 0 |
| 3-Channel Mixer | 14 | 1.2 | 2.4 | 0 |
| TOTAL | 48 | 27.7 | 28.9 | 1.1 |
| PSU / Case | 84 | 500 | 500 | 100 |
| PSU (80%)** | 425 | 425 | 85 | |
| Leftover (80%) | 36 ✅ | 397.3 ✅ | 396.1 ✅ | 83.9 ✅ |
* My DIY front panels are not very precise, so these HP numbers are iffy, but close enough.
** As recommended online, it’s a good idea to work against 80% of your PSU’s max supply to allow rooms for spikes / imperfect module measurements.
Next Steps?
Probably a envelope generator!
