a How-To: Get the copper from a copper penny

Posted on July 17th, 2007 in Hands On/Build This!, How To's, Labs/Experiments, Time Wasters | No Comments »

Yes, so I’m on lunch break >.<
Who knows what a US copper penny is made of? Well….it used to be copper. Now, its a copper shell with a zinc interior. You can get the copper shell very easily, provided you want to play with some acid. Get a penny and make sure its dated post-1982.
File around the edge to the point where you can see a bit of white (zinc)
Get muriatic acide from your nice, friendly, local hardware store. Its also known as HCL, its used for cleaning concrete.
Drop the penny in a glass bowl of the acide, make sure it doesnt splash, and wear gloves….please. After the bubbles stop forming, pour the acide into a sink, and make sure it doesnt splatter. NEVER add water TO a chemical directly, it can boil. always add chemical TO water.
Rinse the penny shells afterwards, and voila!

Thank you 😀

Yes, it’s a huge amount of ram.
Yes, I could probably find a use for it somewhere (vid. editing maybe?)
No, I probably couldn’t afford it
No, I don’t have a practical use for it.

How-To : Light Up Display for Bike Wheels

Posted on May 17th, 2007 in Hands On/Build This!, How To's, Photos/Videoes, Software/Hardware Reviews, Time Wasters | 1 Comment »

Here’s a cool how-to post involving light-up LED images on the spokes of bike wheels.  Now you too can have glowing images displayed on the spokes of your bike!
. . .
Okay, I think this is really cool, for people who actually ride their bikes now and then (that would include me.)  The instructions look fairly simple, and the fact that it all comes in a nice little kit helps a bit too, and makes it easier for first-timers to try their hand at a little electronic magic, soldiering, and maybe a tad of programming.

Quantum Chess. Schrodinger’s Pawn

Posted on April 13th, 2007 in Dumb Things That Happen, Games, Hands On/Build This!, Science!, Time Wasters | No Comments »

WARNING: What follows is a game only a Geek could love.

Today’s design is a twist on the venerable game of chess, via quantum mechanics (See…I warned you).

The above message was brought to you via Chrome Cow. The idea described below is also from Chrome Cow.

The concept of Schrodinger’s Cat is a widely known one. A cat in the box with a device that has a 50/50 chance of killing the cat. While its in the box, the cat could be dead, OR alive. But you do not know until you open the box or observe it some other way. Thus, through quantum mechanics, the cat is both alive and dead at the same time. Opening the box “collapses” the different states into the actual existing state. Now…imagine that concept, applied to chess. And now….i refer you to Chrome Cow, because honestly, the whole idea is kinda confusing to me, though I did spend almost an hour reading it and trying it in my head. I found a few problems, mainly in some of the fancier moves and checks….but, an overall interesting idea. Maybe we can try this in chess club? 😛
Thank you Sean Hyde-Moyer!

=ZAP. POP. Crackle.

Now, this is really cool. I need to figure out a way to do this without killing myself…if anyone has any ideas… 🙂
It looks like he taps a lead onto the plexiglass, and the electricity  just sparks in. Wonder if theres anything special done to the glass. Check it out:

Recycling used CD containers

Posted on April 5th, 2007 in Hands On/Build This!, How To's, Time Wasters | 5 Comments »

If you burn plenty of cd’s or dvds, your bound to have a few of these floating around. Those hollow cylinders that hold your cd/dvd with a foam disc. What use are they once your done?
Well…do you like bagels? I do…
Think about this. Bagel+CD container. Better yet, make it a bagel sandwich, and youve got a bagel to go container. Just make sure you rinse out the cd case before you use it for food….and make sure there arent cds in there 😉
Thanks rodrigo piwonka

What do you do…when your ipod battery dies?

Posted on February 24th, 2007 in Computer software/hardware, Hands On/Build This!, How To's, Photos/Videoes | 3 Comments »

Do you go to the apple store and pay a ton of money to get it changed? could. OR, you could go and watch this how to movie and learn how to do it yourself. Its very simple, and easy. First though, try a reset. sometimes, it may have lost its sync with the battery and a reset will do the trick. Watch the video on Ifixipodsfast

Note: If your Ipod is still under warranty by all means bring it to the apple store, and flashladybug accepts no responsibility for any damage that may result from any attempts to repair a broken Ipod.
