*** Things to do ***

Things to do
  1. Shunt charger
  2. Create LVC circuit
  3. Create better Kart Control (no heat dissipation, stable voltage, has LVC circuit)
  4. Emergency panic switch.
=== Shunt Charger ===
  1. Receive boards.
  2. Test.
  3. Assemble.
  4. Test.
  5. Use.
=== LVC Circuit ===
  1. Check there is 12V switched from Kart control.
  2. Single circuit, operating from that voltage.
  3. Actually turns off Kart control (ie connected to ground, or power wire, or "stop" switch)
  4. Has "Low Voltage Warning" LED, which lights for 30 seconds only.
  5. Completely terminates power (no residual leakage).
=== Better Kart Control ===
  1. Switch-mode power supply ("Buck" supply ?)
  2. Thoroughly tested circuit
  3. Single, smaller relay ?
  4. Includes LVC within the circuit
  5. NOTE ... easy connection when the lid is connected (ie whole thing comes off, for easy connection of new wiring etc).

Future Improvements
Front Stub Axles
-> Buy cheap 6803 bearings through eBay.
-> Bearings arrive.
-> Attend looking for bolts with 17mm shank (for front stubs).
-> If cannot find any ... then call steel supplier http://www.buau.com.au/ for 1020 17mm steel
-> If cannot find any, then consider here: http://www.smallparts.com.au/ $50 RSH170A ........ or change to 20mm bearings.
Later
-> Get the plug finished.
-> Create the female mould.
-> Create cart shell (fibreglass).
-> Create cart shells (final - fibreglass / carbon)
-> Create push bar.
-> Create axles.
-> Add all hardware to the cart, and finish !
