sup /diy/ so I've been burning a lot of bootloaders with avrdude and my handy mkII, but I've been wondering as I *hopefully* will be producing quite a few boards soon, are there any automatic bootloader/programmers, where i can just connect the pins and press a button, and no im not talking a quick link to a makefile, im talking a physical device with an sd card or something, that i can just run to the pins and press a big red button and its good to go
(if this doesnt exist by god im making one)

I need some electricians in here. Preferably ones who are used to working with 240v mains electricity.
Okay, so my current project is to have an Arduino control a relay board, which will control the connection of a live wire between a plug and a socket.
As long as I only tinker the circuitry when there's no power source, and before trying anything I test for continuity, I think I'll be fine safety wise, and it should work.
Pic related, it's da plans

I guess I'm a big dumbass. I recently inherited a classroom from a retiring teacher. The whiteboards were kind of dirty and difficult to erase, so I looked around the web for ideas. I used rubbing alcohol to clean them (which worked well) and then because the writing surface was dull on them, I used some sc Johnson paste wax (again at the recommendation of some nameless blogger). What a mistake, after wiping as much of that shit off as possible, and buffing them with a buffer, it's very difficult to erase the dry erase marker. It smears more than erases. I'm afraid to use some powerful cleaner for fear of damaging the surface (one board was relatively new). What would you guys do?
tl;dr- how to clean floor wax off of a whiteboard w/o damaging the surface?
