hi there all
A few words on Barry Park's amendment to Electronize Speed controllers; first of all the Chip Z409 went out of production about 12-14 years ago; and, when that chip went out of production the Manufacturers of speed controllers use of this chip also stopped.
One set of Manufacturers went over to the PIC chip; the other Manufacturers such as Electronize went over to a totally new design of chip which, although physically resembles the Chip Z409, is totally, totally completely different in every respect.
Electronize's new speed controllers, as in the new 30 amp ones; and the VR series all use PIC chips; any modification to any manufactured speed controllers; will (without the authority of the manufacturer)
VOID their warranty on the said speed controller.
Bear this in mind.So, if it all goes wrong and you send it back to the manufacturers - dont be surprised if you are awarded with a negative response & told to throw it in the dustbin and purchase another new one.
Last, but not least, I think you would struggle to fit these components mentioned in Barry's circuits into an Electronize board. The components' outlay on the Electronize circuits are fairly compact.
You would need to be a gynaecologist/micro brain surgeon to fit them
.
