Roland TB-303: Bass Line synth

• really cool machine with a mod
• mistook the power for center positive, thank god the unit didn't explode
• really cool machine, kinda makes me wanna get the Behringer clone of it, the TD3s

First module for the #modularsynth build

Started the morning collecting these wine crates for the synth casing - really beautiful wood pieces at really cheap prices + they're kind of the perfect sizes

My baby Kawasaki carrying them all hehe i'm so proud of her

First simple VCO build following Moritz Klein's DIY VCO playlist and boss's bin full of random components

• Managed to get a variable sawtooth wave out of the 40106 chip + TL074 op amp + a C549C transistor (for the pot)
• learnt that the capacitor size at the 40106 output controls the pitch of the output wave
• dual battery (in series and not parallel)

I'm really excited to build more and more and have fun with these little modules hehe analog is really sooo cool
