While not in beer, I was just over in London and went to a distillery that let you mix your own gin recipe... Which you then bottled and were able to bring back to the states... Cool experience Anyways, one of the ingredients that I chose was this smoked tea.. It is really powerful and a...

Sign me up! would be an awesome upgrade to my little ebiab setup! Thanks

i was involved a lil with rooting the eris... helped do a lot of testing of roms in the beginning. anyway, i'd be willing to help if needed. however there is one really simple app i'd love to see... one with a huge database of the different beers available that you can simply rate and give...

i just got one last week... did a full boil centennial blond extract over the weekend with it and the thing worked awesome! i disabled the safety feature on mine by never putting that lil temp probe in its holder on the side of the stand... i left it coiled up under the controller box like...

idk if this could be used as well for monitoring the fermentation...... http://www.sparkfun.com/commerce/product_info.php?products_id=8880 it says it is an alcohol gas sensor, like the ones used in breathalyzers.... at the price, i dont know if it would hurt to try.... and if it didnt work...

lol you think thats epic, wait till i add a few more temp sensors since i ferment in that same room, and a photoresistor to measure the light in the room.... finally i could throw a weight sensor on the floor of the fridge to see how much beer i have left in the keg :)... can throw all that...

ok so last week i kinda killed my lcd that i had displaying all the data temporarily *dont ask* so until i can get a replacement for that i needed a way to display my data easily... well here is the solution i came up with... data show an example from last nite into today... basically...

oh and here is a nice tutorial of the relay, explaining it in depth pretty much http://www.sparkfun.com/commerce/tutorial_info.php?tutorials_id=119

there is a transistor there yuri, if you look http://www.sparkfun.com/commerce/product_info.php?products_id=9096 there, you will see it does use a Transistor (COM-00521) :)

http://www.sparkfun.com/commerce/product_info.php?products_id=9096 this is the pcb for the relay control.... basically get all the required parts it lists on this page and then solder them in *really really easy*... as for how it works with the existing temp control... well it doesnt...

ok so here's the crappy schematics i was able to draw up in paint... lol... i tried to make it so anyone can read it with out any electrical knowledge... http://www.guestlinx.com/joe/thermcontrol.jpg i think that should help out pretty well.... so if you take those components, and just...

yup... it sure can! maybe ill comment the code a lil better so you can see how it works a lil better

that's exactly why i switched from thermistors to the 1wire devices... i was sick of the god damn algebra i had to do to figure out the slope of the line to calibrate that *****... god damn graphing, y = mx + b, and having to calculate resistance at precise temps... i love just being able to...

i really dont plan on using it as a saving money build ... i had the arduino laying around... and basically, minus the lcd, the rest of the build only cost me $20

oh... yeah it can easily also be setup to power a heater along with the fridge... thats as simple as adding maybe another 5 lines of code and one more relay using only 1 pin on the arduino
