Re: DIY Mutable Unsuccessful Builds

Anyone any idea on this one? I still haven't got any further. Unfortunately I still haven't got any luck finishing my Jak Plugg Twists. When flashing the STM everything seems to be ok, but when I power on the module the STM doesn't seem to be working. The LED's don't work, neither do any of the cont...

Re: DIY Mutable Unsuccessful Builds

Unfortunately I still haven't got any luck finishing my Jak Plugg Twists. When flashing the STM everything seems to be ok, but when I power on the module the STM doesn't seem to be working. The LED's don't work, neither do any of the controls or cv-inputs. All of the voltages measure correct, no sho...

Re: DIY Mutable Unsuccessful Builds

Thanks! Still no luck unfortunately :/ I really don't know where to look.. Everything seems fine, voltage from IC1 is a perfect 3.3v. Obviously no voltage going to R21 and R22. One odd thing I find is that there seems to be no positive voltage on pin 7 of the TL072 (VCC+). Only VCC- measures -12.. I...

Re: DIY Mutable Unsuccessful Builds

I've had some success here! Did a bit of reflowing and managed to flash the STM afterwards without any problems. Only thing now is that I'm not sure if everything's working correct. Both LED2 and LED3 are off when powering the module (I remember the Plaits LED's were alive even when powering the mod...

Re: DIY Mutable Unsuccessful Builds

Let me try to upload some better photo's here IMG_6599.JPGIMG_3744.JPGIMG_6722.JPG Pin 2 of IC1 is not soldered Thanks! Although it looks like it isn't it sure does connect, as i confirmed with the multimeter. Also that probably wouldn't explain the short, or would it? Might be that i'm missing som...

Re: DIY Mutable Unsuccessful Builds

Thanks for the suggestions! I gave the whole board a second go, reflowed all the components, checked underneath ic's and other components for any hidden traces, but couldn't find any. As for the sockets, I better make sure Vdd and Vss don't connect before moving further right? Don't want things to g...

Re: DIY Mutable Unsuccessful Builds

Hello all, Recently I built a Ripples clone and Plaits clone with success, so thought I could start a Warps clone (Twist) also. However I ran into some problems here, and I was hoping the community could help me out :) While working on this project I found continuity between pin 64 and 63 (VDD and V...
