For connecting to an external antenna, use a mini co-ax cable.

This is useful of you're doing your own senior photos. Instead of shelling out hundreds of bucks for a professional picture, just take your own and edit out the zits.

kewl, now I can sneak some games to school.

I did something similar, but instead of using the mentioned 555, I used a modified joule thief circuit. It flashes twice a second, and runs on 3 farads. the solar cell comes from a cheap garden light, and the blocking diode is a geranium. It was basically made from scrap electronic parts

On one of the buzzer outputs, use a transistor. Then use that transistor to either directly drive your load, or use it to switch a relay.

This is absolutely genius. I need to do this, it'll be nice when the night gets really chilly when camping.

That's pretty neat

They would probably look even cooler if they were RGBs.

You should do a brushless motor variant.

Idk how, but Google Now somehow brought me here, through a search. Anyways since I'm here now, I thought I'd just share how I became one a few years back. I ended up finding out about it through random youtube poop videos. It ended up making me curious, so I finally brought myself to watch a few episodes. And to my surprise, I liked it a lot.

Alright, I'll keep that all in mind. Thank you very much!

You might consider using Li-Ion or LiPo cells instead a 9V. It's much more economical, and they're rechargeable

Dont put them in parallel, put them in series and use a dedicated boost converter. It'd be a pain to make a board to charge all the batteries if they're in series. It could also cause an unbalance situation, unless you use a multi cell battery management board.

Oops, swap series and parallel around in my other reply.

I could see making money from this. If I ever get the chance, I may do something similar.

Thank you, much is appreciated.

I had already did. All that really turned up where those knockoff cells. That's why I had asked here, because Google really wasn't helping.

I see. That does clear alot up now

Some delete them, others encrypt.

I actually dropped my core and it did slightly damage my primary. but it was still usable. I say keep going and if it doesn't work then use another one
