Have you considered using a microcontroller? I have a MPS430 running beside me at the moment as a pulse generator. I imagine that you could use a voltage...
You do not get good temp stability with a 555, if that is important. ... operating at high temp, so I favor a CMOS solution. ... figure out how to get it to...
Nothing is easy! The MPS430 is super low power CMOS and in a tiny package. There is a simple $15 USB driven development device which comes with a free...
Would an Atmel Tiny chip work ? the Tiny family is an 8 pin microcontroller and some chips have analog inputs. not sure how they compare, power wise. Dave ......
... Yes, look at the industrial or automotive temp range. May be too low in temperature tolerance at the high end. You can get one that'll run from 3 volts...

... Good for you... <grin> The architecture for the atmel series chip is optimized for C language or more general purpose use. The architecture for the 18F...
It's funny how in retrospect you wish you'd shopped around more. I got started with the 16F877 and 16F84, and am limited by my unwillingness to get out of the...
They are being used in downhole tools by a few folks these days, but they have to really be careful which ones they can use. Running at 300F and above takes...

I'm having trouble creating a 3" dia aluminum disk .25" thick using a various parting tools. I've made one already but it took much time since the feed rate...
From the description of a 4" dia disc on a .75" shaft, I'm assuming you've got a center hole to mount your disc. Parting is the least fun way to do that....
To All; With the aid of John Moran, of the 7x12 Minilathe Moderator's staff, we have posted my Minilathe Project Drawings and photos on an archive site: ...
Parting something that big isnt any fun in the minilathe. I'd slice the pieces off a little oversize on the bandsaw, then face both ends to thickness. If you...
#1) Start with 1/4" flat stock and cut the corners to make an octogon. then just turn the OD. #2) turn it to 3" and then put it in your chop saw with carbide ...
