What happens after the "then" statement in
For B0=0 to 7
iF pin B0=1 then .....
(This does not)
You can only leave the For..Next loop with a Gosub before the "Next". If I'm off the mark, sorry.....

Jeam, that is what makes the Picaxe easy to use, programming in Basic is easy and comes natural, at least to me. Also, they are Zigbee 2.4GHz ready at very reasonable prices with the transciever boards already populated and ready to go.
The IRFP054N Hexfets are actually rated up to 81 Amps continuous drain current BUT ONLY at 25 deg C. This reduces to 57 Amps at 100 deg C. The 290 Amps you mention is only for NON REPETITIVE pulsing at ONLY 2% duty cycle. This will hardly turn on the motors IMO.... However, if you double up with two...
Can't you use a microprocessor like one of the inexpemsive Picaxe chips ? At 4MHz up to 20KHz PWM and at at 8 MHz double that. From 0% to 100% duty at fixed frequency, unlike the interdependency of the 555 timer where a duty change also changes the frequency. Just a thought.
