If you're willing to buy an RTD measuring device (like a thermocouple, but different) I have a PID controller you can play with, but it only uses an RTD.
You'll need something like this:

I'm pretty sure it will work for you with an RTD, I just bought a Fuji pid for $15 more that would work with J and K TCs. See this thread about the Honeywell PID I can send you:

That's a wonderful offer. Once I figure out what all this electronic stuff out, I may even take you up on it.
Are J and K more universal? I'm striving for a somewhat
'open' design platform. I'd like to avoid designing myself into a corner.
I think you may have already provided a drawing of your wiring diagram. I'll go through your build thread.
If you can think of a useful schematic for dummies...please advise. Thanks again -Scott |

Have you considered using the Arduino and Jim's latest tc4 shield? Sounds like a great match. |

I believe that's probably the smartest way. That would make good use of research already done.
I think I could use that simply as a high temp cut-off at first, then perhaps expand into other uses later?
So now the tough part. Would anyone be willing to build one for me? I bought the board thinking I would get around to learning this stuff..but in real life....
I really like the sound of using that, so if it exceeds that 100.00 $ , that's life.
I'm not looking for a volunteer, cost of goods+time+shipping. If anyone is game ,let me know.
I can PM some specifics about space constraints etc. Thanks,Scott

Ok, after a few conversations, I'm back to my other idea.
I'll continue building a bare-knuckles roaster. No automation. Manual heat control, manual blower control.
If anyone is interested, I will build a second (less personalized) version.
That unit will be shipped to participating members for testing, and possible modification. A couple folks have already expressed some interest.
Ultimately, if it makes the grade, I feel it should be auctioned for a worthy cause, determined by those participating.
I may be crazy, but the voices said to make it look like this;

Sean, I agree.
Isn't that a cookie jar from the galley of a Klingon bird of prey?
Oh, and definitely count me in!

Although reminiscent of popular Klingon design, the design aesthetic is actually 'Post-Modern, Neo Steam-Punk' .
The folks that have already thrown their name in are all a great fit, for the expertise they have in various fields. You're all in.
I still feel a need for someone willing to put this thing through the final paces. Someone very diligent at logging profiles and explaining the resulting cup.
Someone that has the stature to give this thing the official HRO seal of approval.

Oh, man! Once that has a coffee oil and smoke matte finish... wowsa!
If whitey is unavailable, maybe one of us could regular folk could help?

I don't believe there is anything normal about you , and please take no insult. You could never be just a second choice. The more testing , the better, especially given your exquisite posting skill. ...You're in regardless. I think it will be a blast, and honestly,... I build better than I post.
Once again, this will be a 'pass it around' sort of thing. I'm looking at the skill sets present to figure out the order of testing.
More coming soon...... -Scott

Here's a possibility for a drum roaster shell.

Allen,
That's a great pic!! Bonafide Steam-Punk!!
...Still without a research grant, I poked around a bit and got the impression that the bed density refers to the material, and where it falls into the 'Geldart Groupings'
The type of fluid bed one chooses, is based on what group you're working with. Our beloved bean falls into catagory 'D', which is the highest density group. A sprouting bed is a common approach, as well as a shallow bed (bubble?)
On the testing; It seems you have a background in mechanical systems?
Cheers, -Scott |

Glad you like the SP item. I'd love to build a drum roaster someday that looked like that. Someday down the road.
My background has been in the area of boiler plant systems, heating and cooling HVAC systems and the usual auxiliary gadgets that hook it all together. It has helped me in working with fans/blowers, heating elements and a whole lot with controls.

To give a better glimpse of what you're getting into...
We have private confirmation from the gentleman in the white hat. The rest of the distinguished list; Sean, Allen, Bill, Chad. Thank You.
So far ,that would also be my chosen order of testing,.(for reasons I'll explain later) concluding with John D.
As testing and mods come to an end, and the unit has met everyones approval, David(dja) has been kind enough to lend his pouring skills to create a brass or bronze HRO insignia to finish it off.
'Coffee Kids' seems to be a cause that HRO has supported in the past. I see no reason not to, but as long as 6 others have graciously offered their time, the decision is not exclusively mine.
Here's a pic of the first one so far. I will make as many mistakes as possible before building the beta.
Looking forward to the collaboration. Once again, Thanks to all of you for stepping into the unknown. -Scott

For authentic Steampunk (or Klingon) you got to have dial gauges and lots of em! In fact I see a few places on the lower vessel without any at all?
But, to satisfy the high tech requirements of some of the beta testers I'll bet you can invisibly sneak in a thermocouple probe somewhere inconspicuous with no wires showing.B)

Better....I pre-drilled 3/8 holes in the same locations on the back of the unit for probes...sealed off with Hillman press in caps. If there are other things I should prep for, please advise.
Thanks, -Scott |
