Now who wouldn't reply to this great offer.. Good Luck all

I like to program pic microcontrollers using a product called JuneBug and Microchip MPLab IDE. When developing the 110v controller I thought that a microcontroller was not the way to go and 1-wire was a better fit with a software program polling the sensors and activating the 110v module...

chilled glycol loop.. Sounds interesting.. I could eliminate the keg of water in the kegerator to make room for another keg of beer.. :) I can see copper tubing pressed against the cooler plate in the back of the kegerator cooling the glycol and an inline pump cycling the glycol through the...

I do the same. I have been using kodak high gloss photo paper for the printing medium. I want to try clear overhead projector film when I attempt to do a double sided board. Not sure what this is? If you are talking about the RN-41 bluetooth ic.. It does put out rs-232 formatted signal at TTL...

Here is the Bluetooth/1-wire adapter that the host system talks to. This prototype consists of 2 modules a bluetooth module and a power supply/1-wire module. The bluetooth module receives the 1-wire commands from the host computer. On this board you can see the bluetooth chip and 2 leds...

To utilize X10 in the system, you would need to buy a product called ActiveHome PC Home Automation System, you can find it at a website called x10 dot com. This basic system gives you 1-3 prong appliance module(AM466), which would be used to control the pump. It also gives you a module to...

ok dbrewski, lets bring you back into the game. I totally forgot about my first versions of the system. In the first version before I developed the 1-wire 10v switch I was using x10 technology to switch the pump on and off.. I used my 1-wire temperature probes to tell the software when to issue...

Thanks, I sure can put up the schematic. I will need to clean it up a little, please give me a bit of time to do the cleanup. I am using Eagle layout editor v5.11.0 which is a free download from the net.

Thanks for the compliment.. Now remember there is always more than one way to skin a cat. Sorry cat lovers. :) You can build a lot of this from off the self parts. I am just showing what I have done. Hopefully this will spark someones creativity in putting together a system that has the...

The design goal was to be able to place everything inside of a standard 110 outlet box. The 110v sockets are electrically isolated from the dc components by the use of 5v 110v relays. The power for the relays and the 1-wire ic is supplied by the 1-wire network which comes from the 1-wire...

The brains of the device.

The 1-wire 110v switch, it socket can be turned on or off independant of each other. The submersible pump is plugged into the socket and switched on and off via the controlling software app.

Here is a pic of the submersible pump that sits inside the keg.. It just fits through the hole in the top.. I bought it at a local big box store.. GeoGlobal Partners - MD11300

This is a view of the corny key with the power cord, 2 tubing lines and the 1-wire temperature probe.

Yes, I used ice blocks from the freezer in the first system.. I changed them everyday so the water in the cooler would not get too warm. I wanted a nice temp differential for the water going through the heat exchanger. If the coolant got too warm the cycle time of the pump would increase.

The first version of the system I was also using a second cooler with water and ice. However it was a pain adding new ice every 24 hours.. With the kegerator I can set and forget... :)

Here is a pic of how the heat exchange coil wraps around the carboy inside the cooler. Note: With this type of coil wrap, both ends exit the top of the cooler.

Here is a pic of the heat exchange coil and the temperature probe. The termperature probe was made from the 1/4" tubing with a end cap soldered onto the tubing. When I get around to making a new heat exchange coil I think I will increase the number of loops. But for now this works great for...

Here is a view of the inside where you can see the copper heat exchange coil. The 6 gal carboy when placed inside the cooler left me with a 1/4 gap all around the carboy which allowed the placement of the heat exchange coil made from 1/4" copper tubing. The outside area the carboy is filled...

Here you can see the stainless steel temperature probe which monitors the termperature of the wort. The probe is a 1-wire device that was built using a 16" steel probe from brewers hardware. I had them make me a longer one so it would reach the middle point of the wort. A DS18B20 ic from...
