  • Capacitive Discharge (CD) Welder for battery tabs

    Hello,Thanks for posting this, nice project. I'll be building one of these based off this design for making thermocouples. It would be very helpful to see a schematic of your system, or even a block diagram. The actual capacitor bank part of it is well documented, but the digital control is lacking. For example, the MOSFET Gate driver...Is that connected to the gates of all the capacitor boards? The 12v-5v buck regulator, is that JUST for powering the arduino? or is it powering the MOSFET driver as well? Is the MOSFET driver powered with 5 or 12v? If 5v, why use a 12v battery to power the arduino at all? Also, how are your snubbers wired? (flyback diodes) And a schematic would improve the text description of wiring hookups to the Arduino.
