This is a simple project that anyone, with basic skills, can make.
Step 1: Stuff You Need
- Ply or MDF
- solding iron
- colored pencils
- battery snap
Step 2: Getting Started
I always talk in mm as I find it much simpler and easier to use. An off cut is ideal for this around 100mm X 80mm. I have used plastic and cut them with the laser cutter when make a large number of them but that
Step 3: Cutting the Shape
Once you have measured the ply mark in @25 from each side an d 20 up from the bottom. This leaves @ 30 which is wide enough to cover the battery. I used a band saw but a coping saw or any saw would be fine.
Step 4: Marking the Holes for the LEDs
Mark in @ 5mm from the edges and 5mm from the bottom for the bottom 2 lights and where the lines intersect for the top LED and just halve the gap for the middle LEDs. I used 5mm LEDs but any size would be fine just adjust the spacing to suit.
Step 5: Fitting the LEDs
I used 3 red LEDs and 2 green for the Xmas feel but colours are up to you and your imagination. I just pushed them in, a nice snug fit. Push them in with the annode + and cathod - annode cathode so you end up with - + - + all the way around the tree and solder them together. I alway touch the battery snap before I solder them as I quite often get them around the wrong way.
Step 6: Finishing
I use coloured pencils to finish the tree and add colour. Once the tree is together and working I either hot glue or use double sided tape to hold the battery onto the back as it acts as a stand for the tree.
On this tree I used a flashing LED to make the others flash and create a little interest. Enjoy.
