This is an enclosed 1-output AC to DC Switching Power Supply with high efficiency power output of 81%. You can provide this power supply between 85 to 264VAC.
This DIY electronic kit is a simple and fun little 4 digit desktop clock with temperature measurements. The overall dimensions of the clock is 35mm x 80mm x 23mm. This kit is perfect for a small soldering project that actually makes something that you can use!
Power Transistors are transistors which can handle a lot more power in compared to BJTs. Similar to BJTs, the current flow between the collector and the emitter of is controlled by the current flow through the base.
This kit includes the basic components and PCB to help you make a fully functional metal detector! Simply solder all the components together and you have yourself a metal detector with 5cm sensing range.
This is similar to other 16×2 character LCDs that you ve seen before but with one vibrant difference: The backlight is actually an RGB LED. This means that you can change the backlight of this display to any color you want by controlling the three backlight levels. It also utilizes an extremely common parallel interface so code is freely available (check below for an Arduino example). You will need ~11 general I/O pins to interface to this LCD screen, plus an extra 3 pins for the RGB backlight.
