electric hurdy gurdy synthy | about that seed funding money

2018-07-13 09:39:56

I've spent a little on the motor and you could argue that having a 3D printer might forever factor into your projects.. but since my moob removal surgery (if I just say surgery people ask anyway) I wasn't up to my tinkering game and wasn't working on this. It feels dishonest not to share this and I've made sure an awesome project, the #ZeroPhone - a Raspberry Pi smartphone  from this platform got the money instead. @Arsenijs lives for that project and that dedication is what I envy and sometimes lack with my projects. Hope that levels some karma :D

electric hurdy gurdy synthy | 3d printing stuff

currently printing all of this, I already forgot the tooth count and ratio of the gear box, but I think it's something like 1:5 or 1:6. Or maybe it was 1:10. Reminds me a bit of my #Locomatrix - 3D POV - a different approach

electric hurdy gurdy synthy | I've bought a brushless motor

2018-03-15 19:17:45

now what? I need to do some experiments, find out what speeds I need, what kind of gearboxes make sense etc to get the most our of the motor. There are chips like LM74670 that together with a MOSFET can replace diodes for creating a rectifier. First thing that needs to be done is a small gearbox and crank. 

The LT4320 (I'd need three of them) is around 6 Euros each. Ouch.
