I keep a photo-log of the year, going back thru it helps me remember what I did get done. I use social media to drive me to take the pictures in the first place.

and Im ok with using a correction table too! :]
I was pondering this, I do have a bunch of analog halls.

looking back thru images today, it seems as tho I been trying to work out some linear sensors for a while now (about a year)

well, being its me, I'd like to keep this simple, but honestly, I dont TOO MUCH mind throwing in a soic8 ch32 into it if I really have to.

oh I just need a 0-5V signal, I don't care how its made :] In the circuit I built, the balance of the two inductances determines the duty of a square wave thats filtered to get the analog voltage. The idea is that the two inductances cancel out each others nonlinearity :]

well I'm usually going into a 10 bit ADC, but honestly, usually I'm just using a consumer grade pot on a mechanism. I have 2 current targets both linear
One for a mini actuator (4cm)
Another for my tilt and pan mirror (9cm)

If you stay indoors just the right amount of time, then when you look out, everything will be on fire. If you miss it, everything will just look normal again (the normal thats not floods or fire)

Thanks, I often get lost in "arg, but I also need *this*" and sort of forget.
but I'm reminded sometimes, like when mom needs a flashlight to get to the busstop and it takes me 3 minutes to slam one together (Rue: "owww, but I only had red LEDs....")

heh, you just wait and see, something else will come up. I'v watched polprog be inundated with one thing after the next while his life passes him by.

There is a careful balance between the space needed to make things and the stuff needed to make them. Recently I'm a bit overweight.

Hmmm. so it needs to boot a kernel right out of its bios ROM...

no, I'm going for a diode-steered bidirectional ring counter with a diode encoder on it, but I'm not sure the design is working out...
