After failing to create a #symmetric #powersupply using an OpAmp and BJTs to split 24V by forming a virtual ground, I went the easy route. Two #BoostConverter set to 12V each are connected in series with the center being ground. This way I get symmetric +/-12V. Of course I don't rely on the #battery protection, but rather use a 900mA #PPTC #fuse per rail. Also a switch and some LEDs as indicator. Enough #JST sockets for my upcoming #synth projects.
