IT LIVES?

Okay, about one of my old blogs.... "DIY Arduino Mega 2560"

Here is just a little update. Some pictures of the chip smoking up, pictures of it working for five minutes, and pictures of it not responding again.

I ended up burning my USBTiny, but i just had to replace a diode. You see? It's good to have cheap homemade tools.

TIP 31 car

There is not much to explain....

Here is a video:



Pretty self explanatory. Basically I had a model car lying around, so I drilled holes in it and put a circuit in the engine compartment. Looks nice! A23 battery cells are awesome.

Here is the circuit if you are wondering:

I used a TIP 31 NPN transistor. This is a pretty popular project, I just implemented it in something different.
I tried a lower voltage with smaller transistors (e.g. 2n2222)... It didn't work. Still investigating it.

This isn't my first car. The predecessor to this car had headlights, tail-lights, and a speaker. It had a pedestal.
Now, it's burnt out by my attempts to add an amplifier.
Here is a terrible quality video of when it did work:

Just some pictures of it not working.

ooh dusty

Some old stickers

So I honestly like my new revision, because all the electronics are inside the car! The Audi I made before probably burnt out because the AC Adapter says "12v", however it was actually close to 20v

Star Trek Target Practice

I guess I was watching a bit too much Star Trek with my brother. I decided to make a phaser.

Some of you may know that there are multiple types of phasers. I modeled mine after... Whatever it looks like:

I think I was going for Type 2 Phaser 2265, but it turned out a little different.

Here is a video on Youtube describing how it works and all of that.

Like I promised, schematics and pictures!

What you might see inside when you take apart a calculator:

You should mark down where you can solder the four wires:

Vcc, GND, = sign 1, = sign 2

This is just for fun: One dollar scientific calculator. The inside is a sheet of plastic as a PCB! 

How did I build the Phaser?

I had this old scrap wood, it was triangle shaped. I asked my brother to sand it for me. He did an excellent job.

Then I cut an old cardboard tube in half (on an angle).

I found an old bottle cap and drilled a hole in it, for the trigger

Paint everything glossy black, glue it together neatly with hot glue.

Make the circuit, glue those things on too.

In the end I ended up with a pretty solid toy phaser.

If you have the schematic it should be pretty straight forward.
Here is the code: http://txtup.net/HQ8Eg

Here it is also:

/*

this is a phaser for fun. makes laser shooots, zappy noises, reloads needed.

really fun
