1Tree + 1 NE555
I started by soldering together pieces of 1mm brass and copper wire, then I connected one of the ne555 circuit
I then put together the 2nd NE555 using a different value for the capacitor this time and I attached that part to the bas of the tree.
Next step was to add bent rods to hold the batteries in place
I then decided to modify a little bit the design to have only one set of coin cell
