Introduction: Electronic Organism Diverts Attention With Pretty Light, Steals Joules
Mischievous little organism distracts with bright light while stealing joules from batteries, especially ones thought to be dead! Trap one and rest easy knowing your batteries have been squeezed out of every drop. Careful! It has a talent for shining it's bright light at you, which at the right angle could be blinding, or mildly annoying.
suitable for nimble fingers and and a good work ethic!
Step 1: Internal Organs
Time to obtain body parts:
1 x Prototype board (cut down to 2cm x 2cm square)
insulated wire ( in exotic colours!)
1 x Ferrite core
1 x 1K resistor
1 x 2N3904 transistor
1 x Superbright LED (blue or white)
1 x single AA battery holder
thin PVC sheeting (for observation box)
Step 2: Make a Heart!
Now if this little creatures body is going to work, it'll need something to pump life into it!
using to contrasting strands of insulated wire, wrap together around the ferrite core. When it's filled up (about 8 turns) twist together two alternate wires from each side.
Step 3: Transplant...
-Fix the three wires (veins) coming from the core into the prototype board (our skeleton).
-Add the resistor to the board, soldering one of it's leads to one of the single leads coming off the core.
-Insert the transistor into the board. Attach the other resistor lead to the middle transistor lead.
-insert the LED through the middle of the core and through the prototype board.
-With the positive (longer lead) side of the LED on the right facing the flat side of the transistor, solder the outside transistor leads to the LED leads.
-Solder the remaining single wire coming off the core to the positive LED lead.
-Solder the negative battery holder wire to the negative LED (flat side) lead.
-Solder the positive battery wire to the double wire off the core.
Step 4: Contain Your Organism!
Better contain your creature so it doesn't sneak away...
-Make up a net: this one was length: 60mm x height: 30mm x width: 35 mm
A bit bigger than a match box.
-Use a scalpel to cut out of PVC and lightly score the fold lines.
Step 5: Make an Army!
Be careful, they have a way of finding each other! Together their light is even more momentarily distracting, but think of all the batteries to be cleaned!
We have a be nice policy.
