I'm sure it's completely unrelated. haha

You would not find a video very exciting - just me driving around town with a smile on my face. I get some miles on it most every day. Of course I am not pushing your controller very hard. I am testing it as a daily driver rather than a quarter mile burn out machine.

Throttle is still quite bumpy, I am waiting for my hall effect replacement to arrive from China.

Otherwise things have been going well. We have been having 85 degree days and controller temperature has not been an issue, even with my very basic cooling. I haven't seen anything more than 25 degC rise.

Is it the same throttle as before (the new one), or is it the one that worked when you swapped it out?

I am still using the original (brand new) Curtis throttle pot that was causing problems before. My substitute pot isn't in a pot box and so isn't suitable for driving in traffic.

Looking forward to the hall sensor.

Hi Paul
No progress I'm afraid
Before I got the decorating done I came down with something - must be the flu
Anyway I've been crook for 4 weeks now - I can't remember being ill as long as two weeks before

Just been for a blood test - I suppose I will have to wait until I get better

I will !!

[MPaulHolmes]

Just take it easy, duncan. You will be better soon. I'm glad you went and got checked.

Soldered the serial.. And I can confirm now that the rtd command works perfectly.. Now I gonna take things apart to solder ttl level wires on the HIN for the raspberry..

tapping of the ttl serial:



Feeding the raspberry of the controllers 5V and serial connected:

Ahh.. in the picture I forgot the voltage divider.. it works on 5V and so far hasn't broke the raspberry. But i'm including the divider just for safety.. everyone states that the raspberry is NOT 5V tolerant.
