I've just got an markII MR2 pump working in the Supra conversion. My local Pirtek centre did a great job making a hose & finding the right adaptors to suit the MR2 pump. At idle (no moving of the steering wheel), it takes around 20 amps This seems a bit high, others have reported lower currents ...

For those who are interested in higher-power EV conversions, I've just been on the Zilla's home website, and read the shocking news that Otmar is having to shut down production (health reasons) Cafe Electric are doing a limited last order run NOW , so if you want a Zilla, get over to http://www.cafe...

There is a variant of the 8-pin PIC family, that has a built-in AtoD module, and an analogue comparator module (the PIC12F683). Ha ha! I've just realised that's the chip the PICAXE module is using! Good, nice chip. It even has some non-volatile data storage (EEPROM) We could even program (or re-pro...

Ok, just having a quick look over it, and I had a few thoughts: a few resistors, specifically where you have a bidirectional PIC pin acting as an input - if the software goes nuts and sets this pin to be an output whilst you're driving a signal in, you'll get a short through the PIC. Most likely it'...

Sounds like we're both thinking along similar lines Peter! I've been meaning to develop a BMS for a while now, using some of the 8-pin PICs (there is one model that had a built-in AtoD). I design pcbs and program PIC micros for my job, so if you want boards laying out and software written for it - I...

Sorry guys, but I'm gonna have to pull out as well - -
- can't raise the finance quickly enough (and I don't fancy hitting a credit card for this!)

Bummer, I'd like to ditch the heavy old lead lumps.

Hi Peter,

I'd be interested in 32 of the TS-LCP200 200Ah LCP cells,
for the Supra project.

Now I need to go and talk to the building society!

I have (well had, they've been taken out now) a pack of 10 Exide Maxxima 900DC's in the Mini. I haven't really used the pack much, but what a difference over the old 50Ah Dynasty AGMs that were in there. The Maxximas (same thing as the Orbitals) are very stiff, hardly any voltage sag even when they ...
