Larry, where are you getting those prototype boards?

I had the bare boards laying around.... in my electronics stash.  I don't know where I got them... Digikey it thought but don't see there there now.

Here is an ebay store that you can get them pretty cheap, although for the hottop controller it will probably take a larger board.  I'll probably get some boards built for the hottop once I build the prototype, I suspect there will be enough interest in upgrading the hottop.  Last time I had boards made they were about $10 per board...

These are more the size you'll need for the hottop.... it may have to be cut down..

If you have a Frys electronics nearby they would have them too.  and there is always Radio Junk.

One more thought.  You can use these type prototype boards for low voltage/current stuff like the thermocouples, but I'm leary about 110v @ 10 amps through those.... and that's why I use the solder type for the power circuits with larger wire.  Note the thin aluminum contacts on the bottom. 

I vaporized some of those in one of my college labs.... part of the learning though.

On one of my several sojourns at the ASW base in San Diego (that would be FLEASWTRACENPAC), I was in a course that inspired me to do a lot of independent breadboarding in my room. One night I connected Vcc straight across a low-resistance precision (10 turn) potentiometer, toasting it. The devices are quite small.

The next day I was recounting my folly to another student in the hall of one of the lab buildings. Just as a CPO I didn't know was walking by, I was heard saying "Yeah, I smoked a little pot' last night."

His head snapped around and stared in my direction almost involuntarily (as if wishing to pause independently of his feet, which kept walking).

That was about a year after the zero-tolerance success in cleaning up the Navy, back in the early 80s.

some one gave me a PC with a bad power supply many years ago.... seams it kept blowing the fuse... little tin foil around the fuse made it clear what components in the PS were trying to fail (the ones at the base of the column of blue smoke  :-X

Well my laptop is about 98% back to normal (I ended up having to empty and reload it) and finally got all the needed bits back in it, so now back to the Milowidget project.  Hope to let the sparks fly this afternoon on the Alpenrost.  If you don't hear from me by 9 pm something went horribly wrong....

Made a little progress once I figure out I had 5 volts and the thermocouple amp output swapped....

casualtiy- 1 ea. AD595AQ _ $10 mistake...... :BangHead:

After that I'm going to double check all my connections and wiring...

Other than that it seems to be working.  Looks like I need to work on the code a little more... I need to set the initial settings... didn't do that.... need to.

Milo ... I was thinking ... are you familiar with Ron Popiel's Showtime Rotisserie?  Many believe that it is not hot enough for coffee beans.  Would the MiloWidget be able to increase the heat enough or would some modification to the heat element be necessary in order to produce sufficient heat for coffee bean roasting for this baby?

This would make a cheap alternative to a Hottop drum roaster with a drum from CoffeeRoasters if possible.

Although the Milowidget is quite magical, I can't add more power.   The heating element can only add x amount of heat.  Also the appliance itself needs to be designed to handle that much heat too.  The Glass, and other materials (drive motor, gears, etc.) would also need to be able to handle the heat too.

Ok ... thanks for the clarification.  So even if you were able to get a heating element that would generate more heat the glass and other materials would also need to be upgraded to handle the heat?

So that is the bottom line?

Thanks

Think of the stir-crazy.... it has to be modified to add the Turbo Oven or the stirring mechanism eventually melts.  That's not to say that only a larger heating element wouldn't work, but the caution is you may have a Chernobyl on your hands if you aren't careful and just ad a larger heating element.
