There are a lot of Helping Hands instructables out there. But for my version is just using notebook cooler pad that I'm not used anymore. It's quite easy to build and there is a LED to light up what you are trying to solder.
Ok, lets get started !!
Step 1: Parts and tools
- Cooler Pad for notebook
- Some wire that can bend into shape
- Jumper wire
- 4 alligator clips
- 1 LED white
- Resistor 330 Ohm
- PCB Matrix (Stripboard are recommended)
- 9 V battery
- 9 V battery holder with switch
- Shrink tubing
- Male header extended (optional)
- Blackhousing / female 1x1 header (optional)
- Soldering iron
- Hot glue
- Mini drill
Step 2: How to make an arm
Strip the end of the wire
Bend the striped wire in the middle and back onto it self
Put the wire in the slot of the alligator clips, and bend it around the striped end.
Solder it in place for added strength and put on some shrink tubing (Optional).
Make 4 of these.
Step 3: Make the base with Cooler Pad
disassemble the fan, to easier our work on the base.
Make a hole with dremel (mini drill) for each side.
Attach all wires to the hole.
use the hot glue to attach the wire and make it stable.
