    New Retail Programmable Thermostat

    Just wanted to send out another update to this thread for those that are following. The Fermostat is now in production and shipping immediately. All of the Kickstarter and Pre-Sale orders have been fulfilled and units are in stock. If you unfamiliar, the Fermostat is a dual-stage...

    New Retail Programmable Thermostat

    Thanks! Yes they are IEC320 C14 sockets. However, the Fermostat ships with two power cords that plug into the C14 sockets and have a normal 15-5R receptacle on the other end, so it is the same as plugging in your fridge/heater into the wall. I did this to allow for multiple power adapter...

    New Retail Programmable Thermostat

    Just wanted to send out a quick reply to this post to anyone who has been following along. The Fermostat is getting very close retail completion. I have them up for pre-sale on my website for $124, which is a discount of 20% below the retail price. The plan is to start shipping later this...

    Fermostat frermentation controller

    Wow! Talk about being late to the party!! I just came across this post. Thanks for the comments Huaco (and everyone one)! I'm super excited about the results so far on Kickstarter. I am optimistic that I can make the November ship date. It is possible that things can come up to delay this...

    New Retail Programmable Thermostat

    I just wanted to give a quick update on my Fermostat project. I've made some significant upgrades since I started working on this. The biggest update I've added recently is that it will have an SD Card slot to allow for data logging and external program creation. I hope to have a website up...

    Can it even be done? Measuring Specific Gravity using Arduino or Raspberry Pi

    I have also put some thought into this... not an easy solution for sure. I was thinking about creating a container in place of your airlock that has a blow-off valve. The blow-off valve would trip at a certain pressure and then equalize once opened. You know the volume of your container...

    Thanks! I certainly hope that is the case. I believe the price is going to be in the range of $130 or so.

    New Retail Programmable Thermostat

    1) Yes, you can set the rise temperature to whatever rate you wish. The way it works now is you set the temperature difference and the time it takes to get to that difference. So if you set the rate correctly, it can free rise to whatever you want it to be, then continue the program from...

    New Retail Programmable Thermostat

    Hey all! I've mentioned this project before on this site, but it's been quite awhile and the project has migrated some since then. I am an electrical engineer and had an idea last year to design/build a programmable thermostat to control a fermentation device. It turned out really...

    Temp controller build

    Thanks guys! I'm probably up to around $100 or so in parts for this guy, but part of that cost was taken up with buying multiple parts in order to find the correct one. Plus I purchased some spares of several of the "finicky" components just in case I let the smoke out of them during...

    Temp controller build

    Due to a lack of viable options, I decided awhile back to create my own thermostat for my fermentation chamber. After looking at the options available, I wasn’t too excited about any of the temperature controllers I could find. The thought of having to update the temperature manually on a...

    Sierra Nevada Yeast Harvest

    I'm trying to get a yeast harvest from a Sierra Nevada Pale Ale. This is my first time attempting something like this. I boiled about 1/3 cup LME in a pint of water, let it cool to room temperature Sanitized a quart mason jar and added the wort, then drained the bottom sludge from 3 bottles...

    Declining flavor

    It's clear that the answer here is to drink it faster!! :D

    Declining flavor

    One of the beers is a blonde ale and the other is a pale ale that has a little higher alcohol content ~5.5%. It starts out at a subtle flavor fairly quickly, like a few weeks or so, then after a couple months, its very prevalent. Since it's over several recipes, I guess I'd have to say it...

    Declining flavor

    Here ya go rup.... http://morebeer.com/public/pdf/off_flavor.pdf OK, so I guess I should have dug a little more before I posted... :( One thing that I was going to mention was that these last couple of batches were fermented during the summer and my house was warm, 75+ degrees, I'm...

    Declining flavor

    It seems as if my beers are getting worse with age, its been several months and it seems as if they are getting an odd flavor that gets worse the longer it sits. It is kind of a tart or bitter flavor. I have noticed this the last several batches that I have made. This could have always been...
