This build consists of a tiny DC motors ripped from a pair of 9g servos, a h-bridge motor controller, an el-cheapo 8 bit pic and a 100mAh 3.7V LiPo battery. Circuit : (click schematic for pdf) Code: What’s coming next The problem with using these dc motors is that they have a very high rpm….
All the parts were lying around so with a bit of solder and hot glue this is what happened: This was done to test if the motors were powerful enough to push the weight of the matchbox. The answer is yes they can but a change in battery type is needed pretty badly. The motors…
Circuit Diagram: The biased signal generator signal is connected to AnalogIn 1 on the Tiva C which is pin PE_2. Signal Gen and Tiva C ground is common. The two 10k resistors from a voltage divider which will halve the 3v input to give a 1.5 v bias. The signal from the signal generator will…
How it works: Explanation of the idea: With the inductor and magnet combined, ferrous metal objects can be held without any power indefinitely. To release the metal object the magnetic field holding it up needs to be temporarily cancelled out. This happens by pulsing current through the inductor which generates a magnetic field separate to…
