This solar powered artbot based on Solar Engine. The circuit consist of two transistors, one flashing led, one resistor, one capacitor. If there is a light the mirror will rotate and if no light the mirror will stop. I think, It’s nice and fun solar powered electronic project.

Daniel designs this Metronome with a few simple electronic components.The Metronome is any device that produces a regulated audible and/or visual pulse, usually used to establish a steady beat, or tempo, measured in beats-per-minute (BPM) for the performance of musical compositions. It is an invaluable practice tool for musicians that goes back hundreds of [...]

When you need connect your Microcontroller Project to COM port in PC you need RS 232 converter. There are many chip to solve the problem like MAX232, DS275 etc. But if you need simple and chep for RS 232 converter, i though this circuit will be usefull for you. The design made by Wichit [...]

Evil Mad Scientists have create cool and simple Darkness Sensing LED ever. It’s only need few component: a CR2032 lithium coin cell (3 V). LED, an LTR-4206E phototransistor, a 2N3904 transistor, and a 1 k resistor. You can choose it for your first project during learning electronic.
“When light falls on the phototransistor, it begins to [...]

Desoldering is the removal of solder and components from a PCB for troubleshooting, for repair purposes, and to salvage components. The tools for desoldering are solder wick, heat guns, desoldering pump, removal alloys, removal fluxes, vacuum and pressure pumps with specialized heater tips and nozzles, Rework stations (used to repair printed circuit boards that fail [...]

Soldering is an electronics process join together two or more metal by melting and flowing a filler metal (having a relatively low melting point) into the joint. In other words, you use a metal that has a low melting point to adhere the surfaces to be soldered together. The filler metal used in the process [...]
