  Depending on what solder you use, it should be totally safe. Get lead free plumbing safe
  solder. No flux or acid core, no lead (Pb) or antimony (Sb), nothing for electronics. If you're
  super concerned...

  I neutralize the flux with a baking soda & water solution (I keep a squeeze bottle filled with
  a baking soda solution whenever I work with this flux just to be safe.) Then just scrub with a
  brass or s...

  No stress test per se but I'm confident that it's stronger any damage you can do with basic
  hand tools. Honestly, your kettle walls are likely weaker than a properly soldered joint.

  That's going to be tough with a mega. You have to etch a pcb to accept a surface mount
  atmega2560 chip. Those are only available in surface mount. Can you use a UNO instead? That's
  much simpler to mak...

  Is the flow sensor food safe? Couldn't find info on the website.

• Posted in thread: Electirc brewing on 110 is it possible on 07-23-2012 at 12:37 AM
  I brew 10 gal batches on 110V. Total brew day is ~6-7 hrs. Faster if I had a better immersion
  chiller. It's all about time management. I crush while heating for sparge, clean the mill /
  organize hops ...

  I too have the 1/2" heavy duty low speed drill on a monster mill 2 roller mill from northern
  brewer. Works great. Plenty of torque so hold on. Make sure the chuck is on tight. Yes there is
  a trigger l...

  When I got started and learned a lot from this guy.[ame] also used this site a lot were great
  intros to basic electronics if you need it. luck. It's a ton of fun!

  You could probably automate it with a digital pressure sensor and a stepper motor controlled by
  an Arduino. The stepper motor can turn the knob to adjust the pressure. Sounds like a fun
  project.

  I think its more for convenience. With an uno, you don't have to; do much soldering, work on a
  stripboad, build a power supply, and have a separate ftdi programmer. An atmega328 stand alone
  is much ch...
