I'm beginning work on a new screencast series called "Roasting with Roastmaster".

We will start with the basics for folks who are just beginning to use Roastmaster, and will build as we go, covering more advanced topics as the series progresses.

Be on the lookout! 

This screencast shows how to use the “Build Roasts by Yield” feature to quickly create a series of roasts based on a desired yield weight.

Stay tuned for more!

Watch the screencast.

I'll now be posting noteworthy news here in this board, as well as the normal blog entries on the main site.

Thanks for taking the time to let me know - correct on both counts!

Setting aside for a moment the thought of a custom Behmor Interface, this behavior already exists. It sounds as though you are not seeing this - is that the case?

When you choose a valid combination in Roastmaster, e.g. P4, D and 1, you should be presented with the heat curve the Behmor uses. It will display in the console graph.

Then (for example), at first crack, you would press P3 on the Behmor to drop to 50% power. At that point, you would tap the digital readout in Roastmaster, and enter “50”. The curve will enter “Automatic” mode, create a node at 50, and clear out any remaining nodes to the end of the roast.

If, at any point, you wanted to revert back to “Automatic”, you could choose “Convert to Automatic” by tapping the curve button in Roastmaster (next to the digital temp readout). Roastmaster would repopulate upcoming nodes with what they should be on the Behmor itself.

If you are not seeing this behavior, then let me know - perhaps your Behmor roaster definition is not configured correctly, or the preference setting for “Automatic Behmor Curves” is not on.

Hi

Thanks for the kinds words!

Interesting thought about the panel interface - I wouldn’t be opposed to that. But, mechanically, you can do those things already with the standard interface.

If you created the Behmor roaster from the “Add Roaster” list by choosing “Behmor”, it will already be setup to use “automatic Behmor curves”. Whenever you choose Profile, Program and Weight in Roastmaster, it will give you the appropriate “Automatice” Behmor curve. With that curve selected (tap the graph to select through each curve), tap the digital readout to enter each heat change you make on the roaster - Roastmaster will put the curve into manual mode if needed and echo them on the interface.

If you also wanted to track drum speed, just create another “Control” curve in the roast, and do the same. Tap the graph to select each curve in succession. The same logic applies if roasting in the full-screen analyzer. To make it easier, and keep you from having to create the curve in each roast, you could create an empty curve template called “Drum Speed” in each of the 4 standard programs (or 5 profiles). Then, when you selected the program or profile in each roast, the drum speed curve would already be in place alongside the “Heat” curve Roastmaster gives you by default.

Let me know if you want clarification on anything.

Ahh, pretty smart!

Sorry, it took me a few days to finish the RDP documentation. It’s complete now… https://rainfroginc.com/documentation/rdp-roastmaster-datagram-protocol
The Probe Host shown in the main photo was built using

1) Feather Huzzah with Wifi SBC ($17 USD)
2) Max 31855 Thermocouple breakout board ($15 USD)

Both of those, along with the breadboard to assemble them, are available from adafruit.com. You’d also need some wiring along with a K type thermocouple. For all parts, I’d expect you’d spend about $50 USD.

If you chose to do this, you could use the Sketch software I’ve already written available at https://github.com/rainfroginc/Roastmaster_RDP_Probe_Host_For_SBCs

Naturally, this is a DIY project. It would require you to build and solder the connections, then download the software to the Feather Huzzah via the Arduino IDE from https://www.arduino.cc/en/main/software

If you decide to do it, let me know and I’ll answer any questions you have along the way.
