Here's a bit of a ramble of thoughts. - How do you think you'll most commonly use the machine? With the belt vertical or flat? One of my all time favourite tools is a basic linishing attachment for a bench grinder. Like this https://www.machineryhouse.co.nz/L088 . I think using the belt flat can fee...

What kind of sensor are you using for these? I notice that you don't specify what sensor any of the products on your website are compatible with. It might be a worthy addition?

I'm curious as to why you must use a lookup table as opposed to a mathematical approach? Perhaps the speed benefit of not having to do maths is what it comes down to?

Regardless, nice job. This is really good to see. How does this design differ in concept to your other WB designs?

Oh, one more thing. In my example I suggested that the voltages might be different due to sagging. Well that's only one possible scenario. If either of the supplies have any noise on them then this will cause measurement errors. This is probably the most likely scenario which will cause issues. The ...

Shit you guys argue a lot! This is a legitimate problem and the solution is extremely simple!!! If you stop bickering at each other it's actually very basic. Marcos, I'll try and explain the issue as simply as I can so we don't have language problems: Most of the analog voltages on the ECU come from...

I've just had a quick read through the datasheet and you're partially correct and partially wrong. The dividers and whatnot should be powered down when the key is off - this is obvious/necessary. The reference voltage should be set to the same potential as the dividers however. The system would be t...

Where can I find the list of changes required for Spin 2? Because I can't find the list I'm not sure if this has been covered yet or not... I've been reading over the shematics for the spin 1 board over the past few evenings and I'm pretty much up to speed with what's going on. One potentially BIG i...

Ah, you guys must be referring to Q18 and Q19. Yeah, they we're supposed to turn on the 'switched 5V' regulator when the key was switched on by the looks of it. I didn't realise that they had been removed but it does make sense. I'm interested to know why it didn't work. It looks like it should do. ...

I think you already mentioned this, but I can't recall. Is yours a TA card with a bread board/proto board? Marco's plan was to have a kill switch, that's what those transistors where about. His quick stab attempt failed, and I seem to recall it will be replaced with other components.That options is...

The issue is that it's predicted to draw on the order of .25 amps to .5 amps under some fairly common built setups. So the regulator needs to drop (18v-5v).5A = 6.5 watts and we have been planning for 1 amp as extra room for growth isn't bad, so it could have to dissipate around 13 watts. With an a...
