The connector mounting locations include 6 locations for Grove and 7 locations for 0.1" - specifically spaced for the locking Molex SL connectors. In each style 4 of the positions have an offset set of holes for the 90 degree "sideways" versions. This...
Principle The most important component used in the fire circuit alarm is the10k thermistor, as it has a negative temperature coefficient (NTC). So whenever the resistance of the circuit decreases the voltage across the circuit increases, which develops...
This is a spinning top design that uses a Hemispherical Gimbal drive system that has been minimised to fit inside of a hand held toy. The hemisphere will rotate with the outer body. The angular momentum of the spinning top will drive the hemisphere....
Here are the final demensions of my build. There are two shelves each 12 inches wide by 96 inches long. The shelves are suspended from two vertical 2x4s that are attached to the ceiling with 3/8inch lag screws into the ceiling joists as well as 3-1/8...
Circuit DiagramThis is the basic circuit diagram of the obstacle detection circuit. In this circuit, one IR LED is always on. The other IR LED is connected to the base pin of the BC547, since this IR LED is acting as the detector. Steps to follow: Step...

This is a small PCB that goes on the bottom of a 2x2cm LED matrix, and re-arranges its pins into a saner configuration, with anodes on the bottom and cathodes on the top row.
A light metal object, for example aluminum foil with a certain shape is placed between two plates. Then potentials of different polarity are carried on the plates and the object begins to float.With the top plate being charged to negative voltage and...
Since handling Tools on top of a cntsruction site crane is dangerous, the Stand can be locked horizontally and vertically by toggle latches The mechanism below does the horizontal locking.
BCD Watch (binary coded decimal) Hi, How are you? I hope everything is going well. Check out my youtube for more amazing projects. There are lots of watches available in the market, like analog, digital, smart watches etc. So I decided to make a BCD...
