I tried building one a while back but never really got it working well. I used a 555 timer with a pot to vary the frequency and fed that into a octal counter (cd4022) and the output of that into mosfet drivers and several H-bridges of course powering electromagnets. the issue was I couldnt make...

My understanding of the whole raw diet thing is limited, but I think normal mash temps are high enough to remove it from the raw category so boiling afterward is not even the issue. The only brew I know of that might qualify as raw is traditional chicha de jora (an incan corn beer) it isnt...

Could you post a schematic of the 555 pwm circuit? Is the pwm controlling a SSR or are you using a different type of switch like a triac?

So I came up with two recipes, I would like to make the kolsch (I have a lot of other beers bottled but everything is high abv. dark and full bodied) but I dont have the ideal hops for it. Help me choose / modify the recipes. Kolsch 3.00 lb Pale Malt (2 Row) US (2.0 SRM) Grain 35.29 % 3.00...

Its been 6 months since I last brewed due to other stuff happening. I'm looking for recipes ideas for a 5 gallon batch. I have the following malts, hops, yeasts: YEASTS - 1098 british ale 3638 Bavarian wt wlp028 Edinburgh wlp833 german bock wlp023 burton ale wlp380 hefe IV wlp002...

I dont know if you would want to bother with it but you could get a small transformer to provide 220vac the temp controller shouldnt draw much if its just a digital circuit and small relay, so a cheap transformer should work. Something like this would be overkill maybe you can get an even...

Beautiful! strange enough Ive been on break from homebrewing for the same reason (actually due to limited space my cnc machine is blocking the entrance to the closet containing my brewing supplies). I will eventually post pics/videos of mine in a separate thread, but for now can you share the...

I have a very little bit of experience with it. SPICE is really just a backend to a number of circuit analysis programs, try looking for 5spice or the student edition of Pspice. If you can find a decent tutorial and have a decent knowledge of electronics they can make designing and testing...

If this person made wine it could be tannin.

With flysparging Ive found that you dont want the water in to match the wort out. I get better efficiency if I alternate between more water less wort and more wort less water (sort of an accordion method to rinse the grain). Ive also read that fly sparging works best with a low and wide sparge...

If system restore was turned on, those files should be backed up from a previous time. http://www.kellys-korner-xp.com/xp_restore.htm this link is for xp but should work for media center too. You can hold F8 (I think) during boot and try last known good configuration or you can use the windows...

I like them, and considering the amount of time/money needed to list one on ebay what have you got to lose?

I think mulch in general keeps weeds down, bark, pine needles, wood chips... the main reason it isnt an issue for the hops is because by the time the needles are put there the hops are well established and not much is going to stop them.

Its less important in a fly sparge compared to batch sparge but ideally you get the best efficiency when your preboil volume is hit as the MLT is fully drained.

rather than trying to find hops that smell like weed you could try smoking some grain with something that smells like weed.

The only concern I have about blending beer / wine / spirits is the yeast. increased alcohol may kill the yeast and prevent carbonation which isnt a concern if youre kegging also some spirits have added sugar with can restart fermentation, adding wine to beer could introduce wine yeast which may...

I can do a 5.5 gallon batch milling grain to cleaned up in about 3.5 hours if I do single infusion, batch sparge, 60min boil which accounts for most of what I brew.

maybe look for a dunkleweizen recipe and switch the yeast?

to avoid this in the future can you add a second thermo to measure temps at the heating element that will shut off if it gets above 212? If its difficult to do that I think you can even get a temperature triggered fuse as a failsafe.
