Journeys' End

We walk many paths, many roads
Till death halts our steps.
Every day a new adventure,
A new journey of self discovery.

Electronics, it gets the heart pumping

There is it, the new current limited H-bridge for my team's SUMO entry. Put it together this afternoon, and will be mounted on a piece of perspex (which I forgot to bring home) and then mounted on the robot.

Statistics:

  • Numbered of times chickened out of short circuit test: 4
  • BPM while testing: 100 (estimate)
  • Short circuit current: 8A

This is basically 2 MOSFET H-bridge each powered by a LM138/LM338K rigged with 150/150K for R1 and R2 respectively, providing ~13.5V.

Cheers,
Steve
