I haven't used the SCR dimmer, so a grain of salt required. The voltage regulator @ 3 amps should be fine for the brown pump, rated at 0.9amps. The heat sink is not overly big and the unit may over heat (Id guess it uses a LM338 regulator, which has inbuilt protection, it cuts out if it gets...

I was playing with a PID loop hooked up to a paint stripper heat gun controlled using a thermocouple used for roasting coffee beans, the following link has code and references etc http://www.arduino.cc/playground/Code/PIDLibrary

Another day and I have learn't something new, thanks for that. I hooked up a SSR this morning and plugged in the multimeter, changing pins to a PWM pin helped and as advertised it gave a proportional control. I still think a software implementation that uses one or two seconds as the cycle...

I dont use a heat sink for the SSR. Mine are screwed onto the wood sides of my homemade scrap timber box. Even though your fridge is connected up to a 10 amp socket it doesnt draw 10 amps. A typical fridge draws about 600 watts while the compressor is running, current=watts/volts, so the...

The STC probe is a thermistor, that is the resistance of the probe changes in proportion to the temperature (logarithmic relationship). You can measure a thermistor on the arduino using a voltage divider circuit and an analog input. You then need a calibration equation to turn the measured...

I use solid state relays, cheaper and more reliable than mechanical relays. Try these units on ebay http://www.ebay.com.au/itm/SSR-25A-Solid-S...=item3374d92225 Less than $5 delivered for a 25amp controller. The solid state relays are also suitable for proportional control via a PID loop. The...

I am on tank water and have an above ground line going to the shed/brew house. During summer the higher water temp and higher ambient temp means my immersion chiller on tap water only gets the wort to about 28-30. Leading up to brew day I use a loaf sized baking tray to freeze blocks of ice...

I bottle prime using the two sided measuring spoon. It isnt much use in its standard form if you want to correctly prime anything from a stout to a wheat beer. I have cut the slot on one side quite deep and then use a variable height of electrical tape to get the correct dose. I check this...

Thermocouples are generally for higher temp applications up to hundreds of degrees. Rtd's operate in the range for brewing temp control. I have had identical units next to each other and they can have 1-3 degrees difference. I prefer the Dallas one wire device via a Arduino controler. Even...

I was looking forward to seeing eddie cry. great game from the cats

l I use the oven process with the added step of "capping" the bottles with 50mm squares of alfoil. I cut the alfoil and putit loose it in the oven with the bottles. After cooking the bottles I wait till they have cooled to the point of just bearable to touch and "cap" each bottle with...

Newbeer, Have a look at typical IPA recipes on the recipedb IPA Recipe Database Your recipe is missing the "dry hop" addition. These are hop additions generally made to the fermentor after primary fermentation has ended (so bubbling CO2 doesn't drive off aromas etc). The dry hop...

I was at the BABBS water night in April. There were 3 beers all brewed the same except for the water. One was RO, the second Brisbane water and the third burtonised water. I cant recall exactly the beer, it was a dark beer, a stout I think (I haven't nurtured the brain cells that held that...
