I think I've had three of the 150-200 units I've done, that have been like that. One I could fix (I think it was a bad connection of ISCPCLK between the two boards), but the other two were working fine, but just wouldn't program and I couldn't figure out why.

@Onkel_Udo: Thanks for your input! I will propably not move forward myself (as I don have the tools and time + the already functioning setup I have). I started the thread mainly to went my frustration with the current options on the market and see if there weren't others with similar ideas. I do...

I agree, and I must say I really like your design. Very clean. I'm sure there would be buyers for that. Ideally, I'd like a smaller (shorter) mill that just 'plugs' into the grinder motor, just like the meat grinding auger. Free standing. Just place the motor on a stool, with the mill part...

@AnOldUR: I've seen that before (in the motorized grain mill thread). Very sweet setup, but still pretty hefty. @Onkel_Udo: Cool :) Of what I can gather from the web, the phil mill works pretty well and is very compact. I like that. Still the mattmill kompact might be a better 'start' for my...

Yeah, I know about that, and I know some have tried it with mixed results. Bottom line is, it is not a roller mill... I don't nedd to mill in the kitchen, I just don't want the mill to take up so much space, and be easier to clean. I live in northern sweden. I'd rather mill indoors most of the...

@wilserbrewer nice to hear your input (and that great minds think alike) :) I agree that a good crush and 'automatic' operation is key. But I'd really like something that is more the size of a kitchen appliance than furniture :) It might be the case, as you say, that it might as well be...

Hi! There are a lot of options when it comes to malt mills. I myself own a monster mill three roller that I motorized with the motor from a cheap meat grinder. It works very well, so I really have no reason to complain. Except... Even though my setup would be considered 'compact' comparing...

I took inspiration from another sketch that implemented a PIC programmer uing an arduino, but ended up rewriting pretty much all of it. That sketch used three digital pins to provide power for the target for programming (you need several pins to provide the needed current). I ended up just using...

While 6 probably will do just fine, you don't have to use PWM to control servos. The timing is pretty lax, so you can easily (perhaps even easier than trying to coax PWM into doing the job) use any digital output pin to control servos. And the micro servos are really puny. It might better to...

See attached image of how I envision it. Regarding the clever method of attaching the servo, it would depent on the setup you're using. Binder clips might work, or maybe you'd need make some kind of bracket.

Maybe I explain like crap :) Google "RC servo" if you don't already know what they are. Just attach a cup or something similar to it, and have the servo dump the contents of the cup, over the kettle wall and into the wort. Small RC servos are really cheap on ebay.

Here (in Sweden), university is free. You also get a small grant each month when studying and anyone can get a student loan (that is very beneficial). We also have universal health care, 480 days of paid parental leave (per child) and lets just say gun violence is not a major concern here...

@p_p : Use a low wattage heater. A long heating delay is also good. Once fermentation is complete, it doesn't matter as much. Doesn't matter if it takes an hour or a day to reach diacetyl rest temp. You just don't want to heat more than you have to. This has been up for discussion before in this...

You probably could experiment with: * insulation on the probe (less of it) * hysteresis setting (hy) * cooling delay (cd) * and of course, if you do use a heater it should be low wattage (as in ~30W) and you should not use it if not needed. You might be able to get less swing, but as others...

Hasn't dental floss and fishing line been used for dry hopping with hop bags since the dawn of ages? I can't imagine that 1) anything could be seriously wrong by doing so and 2) that we wouldn't know so by now, if that was the case :)

Ok, so it seems something has changed with newer versions of the Arduino IDE. Thanks for reporting this. I'll look into it as soon as I have the chance. Glad you got it working by downgrading though. Cheers!

A simpler idea to implement, would be to just use cheap rc servo motors. Just fix a small container on an arm (maybe a couple of inches long) and attach it to the servo. The servo can be hung off the kettle wall and keeps the additions away from the steam. Just add more servos if you need more...

Not that I know of. There is no chance. It won't work.

@hidara: That looks like a sweet board, I haven't heard of it before (but tbh it is a bit pricey). You are treading into the unknown, so I think you are on your own here. These are ARM boards I take it, so there is no guarantee that it will work, but being Arduino compatible does increase the...
