Pretty cool! We modified circuits inside a miny battery-powered sword/light-saber. First we took out the two main screws and studied the different components of the toy. There was one speaker, and LED, a green circuit-board, two lithium batteries, and a t...
Amazing! There was one special bettery among the hundreds in our room. My partner and I assesesed the voltage (V) of the battery before lunch. It was 2.68 v. We then checked after lunch and it had increases by point 7 V. Then the real fun started. We ne...
We worked with Lightsaber toys. These are battery-powered, simple electronic items. We opened up the plastic chassis and removed all the different components. We applied the knowledge and formulas we learned into assesing the model. There was a circuit bo...
Zombie Battery Update- We sandwiched the Zombie Battery between two normal ones and we observed that the Zombie consumed the energy from both the normals. The normals had decreases each 0.25, and the Zombie went up 0.5 V. SOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO...

I documented all the steps I took in dissassembling my Ryobi Drill. Here they are! Press ctrl and scroll up to zzom in.
We broke open a DVD player and saw the different components. The way we broke the player and hacked into it will not be of any interest to you. (Hint: The sledge-hammer method.) We saw many capacitors, resistors, and batteries, all varying in size and col...
We connected an LED lighted fan to a 9-volt battery. We made sure not to stick it on our tongues. We then put four rubber-bands through the four corners of the fan and connected them with four markers. We took of the caps of the markers and turned the fa...
There was a hopeless muddle on the table. Parts of electronics and dead batteries. How do you make a robot out of it? Pure intelligence— ME! …………..And Alec ofcourse. I wouldn’t call our robot a robot. I’d call thi...
