Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Materials

http://parts.digikey.com/1/parts/552613-ic-avr-mcu-8k-10mhz-8dip-attiny85v-10pu.html  attiny 85v - 10 PU

a toner printer or something to copy the pcb layout (see pic 1)

Capacitors,Transistors and 2 Ir Leds

1-1 k-okm Resistor

2-47 ohm Resistor

1 led

1 swich










Step 2: Print the Image,

1-With a toner printer, print the layout in glossy paper

2-put the design in a pcb and stick it with tape.

3-With an iron,"Stick" the design for 1-3 minutes

4-while it's hot, put the pcb in water for 15-20 minutes

5-Then, remove the paper, and volia,There it is, but don't shout i finished already...

Step 3: Etch It!

1-Buy some ferric chloride

2-put it in a plastic bowl

3-Put the pcb in the ferric choride and wait 10-15 minutes.

4-Then carefully Remove the pcb and put it in water.

5-The pcb is finished

Step 4: Drill Some Holes

After the pcb is ready, take a 0.5 drill bit and do some holes

Step 5: Soldering

Solder the components like this

Step 6: Finished!

Finnaly,You have finished.Now, enjoy your new tv-b-gone

    terrible! simply terrible! and i'm being a kind as possible! where should i find a mini capacitor (the blue ones)? i belive you need an 8Mhz resonator. IF you can layout your PCB i think you could include a more detailed part list. i understand that my criticism may not be "kind" so i will leave you on a positive note. Please buddy do try harder.

Why is this world dumbing itself down for to get pins on pinterest? i understand that my criticism may not be "kind" so i will leave you on a positive note. Please buddy do try harder.

    considering the lack of vital needed information they they had to use in order to build this, i have doubts they made it at all..

    if u had built it u would know the values, components and the code that went into it.

    Exactly. No info on etching the board, no info on programming or code, lack of part numbers and values. A 0.5 what drill bit? You mean 0.5 inch or mm? (I know the difference, but many might not.) This looks like what I've seen inside a few of the key chain models. Where did this come from?

    Ummm... Why are you people focusing on the negative?!? He already mentioned this was from a store bought kit. duh.... please read before you post. I think it's great someone his age is even interested in fabricating the electronics, not just buying pre-assembled and using.

    Look at the dates. He replied in a post that it was from a kit more than a week AFTER my post (to quote you "duh"). Please check your dates before you start flaming peoples posts. It's the only place he admitted it was from a kit. If you read the whole ORIGINAL instructible you would have noticed that it wasn't mentioned anywhere.

    At the start of the "ible" there is a link to buy the kit online...... >.> To quote you (please read the whole thing before you post).

    It seems like he just bought this and opened the black box so that we just see the circuit and on step 4 all he did was turn the circuit board around!

    A Capacitor Holds Electricity And Emits It All After It Fully Charges A Bit Like A Water Bottle Rocket.

    Would it be possible to make a small wire so I can make the LEDs farther from the board, same with the button, can it be done?

    Please don't be so negative give him the benefit of the doubt because I'm SURE these are all actually verified before they could win anything....RIGHT? Hmmmm???? And if not, shouldn't they start? Just curious
