I was sitting in my hotel room this weekend with nothing to do but browse HBT. I read the DYI Stir plate thread and decided to give it a go. Now I'm pretty far from home so I had to buy everything. Its almost done but I still have a couple questions.
I bought everything from the original list except the rocker switch. I dont think they sold that style anymore so I got a similar one.
Heres a pic after I mounted the switch and rheostat:
Now I didn't think I'd be able to juice it up today because I had no spare phone charger, but then i got an idea,.. I asked the front desk if they had a box of chargers that people left behind. they had about 50 of them for me to chose from. I grabbed a BB charger and hooked it up.. Here's my first Q: the charger is only 5 volts. will this be sufficient of should I really find a 6v like Anthony used? It spins pretty fast and seems like it could work, but i haven't weighed it down with washers and magnets yet.
Both wires on the charger were black so it took some switching around to finally get it working!
Believe it of not, the biggest fender washer Depot had was 1 1/2" . Again, a 2" is used. should I look for a bigger one elsewhere or can i use the one i have?
heres a pic of it all closed up. I know I mounted the switch upside down, Ill flip it around once I mount the magnet.
So far, this thing is so silent, that i have to put my ear to it to hear the speed change when turning the rheostat. I know it doesn't run hot, but should I give it any ventilation?
Couple more Q's:
I don't have a spare hard drive to salvage. Is a rare earth magnet really necessary? why cant I just use any old magnet? If I do need one, are there any retail stores that sell them or do I have to order online? same thing with stir bars,. can these be made or do i have to order?
Special thanks to Anthony Lopez for posting the "how to" on this. It was really fun and super simple to make.
