Step 2: Materials and Tools

"Battery" Piece
Bamboo stake (available at garden centers)
DC adapter
Aluminum foil
2 pieces of bare copper wire
Markers to label the polarity

Conductor Piece
Bamboo stake (quantity depend on the number of batteries you are replacing)
Aluminum foil
One piece of bare copper wire per conductor piece

Wire strippers
Hot glue gun
Soldering iron
Sand paper

I did this once with dowels. I stuck thumbtacks in the ends for contacts after twisting wire around the shanks of the tacks. I taped the wires to the outsides of the dowels. I drilled a small hole where the lid fit the battery compartment. I didn't use an AC adapter. My setup used a 6V rechargeable burglar alarm battery on my belt to power an electronic camera flash that originally used 4 AAs. I got many times the number of flashes per battery dollar that way.
4x1.5v = 6v. Why 9v?<br>10.6v? messure the connection on the &quot;battery&quot; when the light is on.. it need's a load device.<br>
This design needs a current limiting resistor to imitate the internal resistance of the cells you have in line.
None of these instructables that show this method of doing this mention what you just mentioned. I've wondered what resistor I should put on a usb source (5vdc) when its going to a device capable of 1 to 2 AA batteries. I know its 1.5 volts for one AA and 3Volts for a 2 AA battery setup. But im wondering what the color code would be on the resistor that I would need for either situation.
why do you need the extra fake batteries? Won't just the adapter battery work?
Yes. You would have to jumper it but you don't be able to power it with more than one cell.
