StorageBot – voice controlled robotic parts finder. The hardest parts to find were always those rare miscellaneous parts that were thrown somewhere into a “junk” bin. StorageBot solves the location problem by listening to your voice commands, processing the location of parts from a master database and then delivering the matching bins in a manner [...]

That kind of photo is actually an animation that consists of several photos of the same product but from different angles. It means that we need a device that can be controllable and that could take pictures on even intervals. Roughly, the device consists of PIC16F628A microcontroller, USB<->Serial PL2303 converter IC, ULN2803A IC transistor array, [...]

A mini-drill machine is always needed in drilling the PCB (Printed Circuit Board).It is usually powered by batteries that limit the drill’s capacity.Using a power supply adapter with a speed regulator like the one featured here can certainly improve the performance of the drill.With the help of this revolution regulator circuit you can control the [...]

Inductive charging uses an electromagnetic field to transfer energy between two objects. This is usually done with a charging station. Energy is sent through inductive coupling to an electrical device (base of toothbrush), which then can use that energy to charge batteries in arm of toothbrush. Induction chargers typically use an induction coil to create [...]

This soldering station is  designed to control the temperature of soldering gun Solomon SL-1 and other similar soldering devices with integrated thermocouple. DC voltage generated by thermocouple is amplified by operation amplifier CA3140.The precise regulation and excellent small hysteresis of temperature is obtained by voltage stabiliser LM723M (military packaging). LM723M contains an embedded temperature stable [...]

Generator functions, or forms of waves, such oscillators are producing alternating voltages of different shape which correspond in appearance to a mathematical function.They can be sine, rectangular, triangular, in the form of stairs, etc.. Applied in analog and digital electronics, the measurement and experimental techniques, for educational or professional purposes and as a laboratory device [...]

The small electronics with a few transistors and a few passive components will revive a dozen of small LED sparksdeployed in the shape of the flame of the Christmas tree candle .Failed attempt to blow off the flame, like a birthday cake, now become reality. Accumulated air in the children’s swollen cheeksmake magic explosive “puff” [...]

If you want to connect your PC to your house cinema, built VGA to VIDEO Converter.The device is suitable for watching movies, performing video presentations and advertisements from a computerthat does not have video composite output signal.Conversion is a stable, high resolution and high image quality in terms of brightness, contrast and saturation of colors.Most [...]

Most older engines, and many newer ones, have timing marks in the form of a line marked on the rim of the vibration damper.Some engines in front-wheel drive vehicles have timing marks on the flywheel. A pointer is attached to the timing cover.When the mark is exactly under the pointer, the engine is ready to [...]

Phil from jumperone.com he wanted to try to write software for Microchip PIC16F883 microcontroller and he couldn’t find simple development board for it. And so he decided to made own development board. Source: jumperone

If you want to give life to the old table lamp, replace the orange “hot” light with a clean, “cold” and white, built the project with white LED diodes as the light source matrix.The continuous change of the light source you can build the proposed electronic-switching regulator in pulse width modulation.Associate surrounding red light only [...]
