Step 1: Tools and Parts

The tools needed to create BatteryBot
Soldering Iron
Clean work spot
[Needle nose pliers]
Wire strippers
Wire cutters
Lighter or heat gun

The parts needed to create BatteryBot
[2] 1.7volt LED
[1] 9v battery lead
[1] 9v battery
[1] 330 ohm resistor
Heat shrink
[2] (1/4) x11/16 in length
[2] (1/8) x3/4 in length
[2] (1/16) x15/16 in length
length can be adjusted
Electrical tape
Wiring Loom (3/8) x 1 in length

Yes I know I have the worst camera ever

Step 2: Lay out components

Step 3: Find the negative (cathode) side of the LEDs

mark the cathode of both LED's with a black sharpie.

This is the short lead

Step 4: Shape 330 ohm resistor into suitable head

Bend the resistor to fit the width of the large diameter (1/4)----11/16 in length of heat shrink tubing.

Step 5: Solder LED to resistor

Hook the ends of the resistor and LED
Solder joint so the LED and resistor are straight in line

Bend the wire on the LED side for a tall head
Bend the wire on the resistor side for a short head

Step 6: Solder second LED to resistor

Repeat previous step for the other side
Optional: (trim excess of lead in order to keep the arms the same length)
Be sure that one side of the resistor has a negative LED lead soldered to it and the other side has a positive

Step 7: Prepare the ends of the led leads

Measure the width of the head unit

Clip leads so they are in line with the width of the head

Make sure the leads are approximately the same length

Step 8: Prepare the power supply unit interface

Slide the small diameter (1/16)---1 in length of heat shrink tubing onto the leads

Step 9: DON'T FORGET !!

Slide the small diameter (1/16) ---1 in length of heat shrink tubing onto the leads

Step 10: Solder battery connector leads to components

be sure to have the black wire(-) connected to the negative (cathode) side of the one LED

This side was the one the WAS slightly shorter
It will be the side with the flattened spot on the plastic part of the LED

Solder the leads so they are straight in line with one another

Step 11: Solder the positive lead to components

Be sure to double check that the connections have been properly made

Note: This might be a good time to check that the system works by attaching a power a source
(AKA: a battery).

oh man i nneeeed some LEDS. i have to ask my mom and dad if they can buy the magnets, LEDS and lithium batteries for me.
find them in old things like well any old tv the on and off sswitch should have one
 never take apart anything with ray tubes(ie: tv's or monitors)  They hold charges for a very, very, very long time; so it is easy to get the shock of your life if you mess with one. Leave that to professional TV repairmen.

no unless your messing with the ray tube there shouldnt be a problem if youre worried use insulated screwdrivers and wear gloves

lol i steal mine from my dt department in my free periods :) they have draws and draws full of them

I cant understand why you have VERY crappy pics and your instructable is rated 5 and my instuctable is very good pics and explanation and it is rated 0! aaaaa i am very unlucky man i am going to cry

Cool! Now you just need a little piece of muscle wire to make them wiggle! You can get a meter of wire for under $20 - that should be enough for at least a dozen of these little guys.

very nice idea! i will definitley make some of these tomorrow

Sorry if this was answered or a lame question but do you have an approximate lifespan on one of these robots (err, the batter rather)
Woot! Battery man! Lol make like 20 of them and put them on a usb cord for an awesome decoration! :-D nice one!

Wow thats is seriously cool. Keep up the good work. I might suggest it to the new instructazine collaboration if you don't mind. Although it might be quite long till the instructazine gets completed, as most of us is at work or school :/ . So do you mind if there is a possibility that your work gets used in the instructazine magazine?

That would be Cool! :)

Aww, that's adorable. I'd like a swarm of these dudes.
Excellent instructable, laid out well enough that even a klutz like me could follow it. I wish others went through as much effort to create as complete an article as you did.

cool these would be fun to make itd be cool to have a army of em and dress em up in mini camo with mini guns
