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!):




Here's a close-up with Optimus Prime. The picture does not do justice to how it looks in real life!:




Here's another photo with the ball rotated (as in animation):
