Build your own MP-scaled Vector Sigma with LEDs.

Ball is 4" in diameter. Use x-acto to cut open half way. Use x-acto to completely remote LED assembly 5mm Warm White Straw Hat Water Clear LED bulbs can be bought here: 3mm 5mm Flat Top Water Clear Straw Hat LED Diodes White Red Light Bulb This part's a little tricky. Solder together as many bulbs as you can into a "ball". Be sure to keep positive and negative ends from touching each other. It's tricky, but it IS possible. For me, I first got them in groups of 3 and soldered them together. Then I got 3 trios together and made two "hemispheres" (9 LEDs each). Finally I soldered the 2 hemispheres together. Overall I used 18 bulbs in the picture here. Use wiring technique shown in previous video and solder wire ends to the bulb group. Use 3mm drill to create a hole at the bottom. Send the wire twisted pair through and install plug end to connect to 3V power supply. Use clear acrylic rod (or even a paperclip) and cut off appropriate length to stand the bulb group at the center of the bulb. (I used a.1.75" cut) Use glue gun to install. Connect to power source to confirm. (I use a 3V 1A AC adapter. Very cheap on ebay) Use glue to seal. If you have the original MP-10 Vector sigma, you can use the stand. If you have a key to vector sigma, use x-acto to carefully cut an opening to fit the key. (you may want to do this during step 2 actually!) Close up with Prime. Picture does not do justice to how it looks in real life! Another pic with ball rotated (as in animation) Thanks for checking it out. Feel free to ask me any questions.
