Wandelende takken, stick insects, stick-bugs, walkingsticks, stick animals, or bug sticks?
First assemble the PCB (see links to images below), the green circle is the PCB, the traces outside of the green circle are wires going to external components.
It can be helpfull to see the assembled PCB from the top side.
After soldering the PCB you can mount it to the stick. i use 1 second glue and a tyrap.
I drilled tru the branch to stick another stick thru for the arms.
Make the wood a bit flat on one side where you want to mount the motor, because the motor has a flat side. Then you can use one send glue and a tyrap to mount it.
To connect the motor to the other branch (the legs) drill a hole that is a little bit smaller then the motor shaft. File the shaft a but with a metal file. Then add a bit of one second glue in the hole and stick the shaft into it. Make sure you add just a little bit of glue because if the glue goes into the gear box (via the shaft) your motor will be dead.
You can see the flyback diode, this diode is there because when to motor stops getting power it will start to generate power and it will be pushed back into the circuit. This can cause the chip in the blinking LED to behave abnormal, and make everything work les good. I did not add a capacitor over the diode here, but it can help with stabilising also.
Make the stick flat witha gap in the ceneter for the wires, then you can glue it to the stick and mount it witha tyrap. I put the tyrap on a place where it is not blocking the light on the cell.
You can cut the legs and arms in places where you want the elbows and knees to be, then use springs to make them hinge. You can bend the end of the hinge and drill a hole to stick the wire into, this way the legs and arms will not fall off after a while.
