I'm making progress.  Hardware interface is complete (interface board is re-designed).  I'll probably order 25 boards.

Working on a mounting design.  I think I found a good cheap project box that fits nicely on the hottop.  I also have a touchpad on order that will hopefully go to the right of the display.

USB interface for datalogging and PC control.

Now the plan is to see how fast I can get to 1st crack.... baseline the hottop so I'll know how fast of ramp is possible.

I'm guessing you too believe the widget is impractical for the gas-heated Sono?
Nope, I think it would be perfect for the sono.  Two tricks to that.

1) - be able to adjust the gas pressure (I have a device that will do it, but no Sono to test it on (since you sold mine)
2) - reading bean temperature ( might be easy to just poke one down in the beans and have a thermocouple jack to plug it in.

I've got a 2-stage gas valve, but a true variable valve was too expensive - something like $500 IIRC? And hey, I'm going to buy another Sono, and you can come visit it anytime!

Oh, contrare senor... here is the animal you want, and only $125




Tricky part is installing in after the on/off pressure valve already in the sono.  You will need to do some gas plumbing.   you might need the signal conditioner... which is another $90, but maybe I'll include an amplifier in the interface board.

BTW, this is the modulator valve used in later Ambex models with full gas control

Wow! I've got a lead on a Sono from a local shop, so I might be in need of this sooner than later. I wish Continental was still in Houston so you still had business here?

8), Nice looking mount!
The advances Homeroasters have developed for monitor/control/datalogging for homeroasting in the last year+ have been amazing.

What did you come up with for speed on the ramp.  Running full on with 250g I have made it in around 7 minutes.

wow 7 mins that's fast.  With 230g full on and fan speed at 1 the fastest I can get to 1C is
about 9 mins, dropping the beans at about 300-310F.

Your work on this fascinates me. Now that I have added a Android tablet to my equipment arsenal,
(a Motorola Xoom with a USB interface) I might be interested in acquiring some of this equipment for my Hottop when you have finished your extensive research. Do keep us all posted.

Do you think this will allow control of a Sono for different amounts of bean mass? There is a used one locally...

I thought I saw Milo taking orders for the Milowiget at the show, am I wrong?   ;D

I actually go to see and touch the Milowidget on Sunday.
