5V-12V AT89C2051 Multi Function Six Digital LED DIY Electronic Clock Kit Description:   Circuit board is made of FR - 4 glass fiber, tough and durable plate. Reasonable circuit layout design. Use your creativity, diy your LED clock! Voltage: 5V-12V PCB Size(Length x Height): 10cm x 5.2cm / 3.9" x 2" Function: clock /alarm /countdown /stopwatch / counter   Package included:   1 x LED Electronic Clock DIY Kit

Working principle: Using the SMD CD4060 control 12 red, yellow and green LED flashing, adjust RP1 can change the speed of flashing, while the music chip issued a wonderful music. The kit uses SMD components and plug-in components, is ideal for practical training requirements. The CD4060 consists of an oscillator and a 14-bit binary serial counter bit. The oscillator can be configured as an RC or crystal oscillator. When CR (pin 12) is high level, the counter is cleared. All counter bits are master-slave flip-flops. The counter counts on the falling edge of the CP (9-11 pin) pulse in binary. Since the Schmitt trigger is used at the clock input, all inputs and outputs are buffered for unlimited pulse rise and fall times. Note: This is a DIY kit, need to be assembly. Not supply installation manual. Package included: 10 x SMD Music LED Light Kit Complete assembly for reference only:

Unassembled DIY Geeetech I3 Pro C Dual Extruder 3D Printer Kit Support 5 Filament Note: We default deliver EU plug, if not suitable, please use your own plug adapter or plug strip. Feature: The DIY Geeetech i3 pro C is a dual extruder 3D printer with laser-cut acrylic frame. The Geeetech i3 pro C is fast, easy to use, less costly, and great for builds that don't require super high precision. This Upgrading Prusa i3 use two colors or materials always seemed complicated, but we make it so simple thanks to our optimized design of both hardware and software. Newly designed control system-GT2560 3D printer control board, a perfect combination of Arduino Mega2560+Ramps 1.4, making 3D printing fancier and easier. Now with the dual-extruder, you can print a single two-color object, or you can print two objects in one print job, each made from a different color. You can also print one single-color object, as with other single-extruder 3D printers. Or you can use one extruder for infill or support. The 2 extruder motor pushes filament through 2 head separately, so mixing colors printing is not applicable for the moment.   You can also use the control panel to print directly from the printer's SD card slot. You will need a computer to load design files directly onto the SD card, but once those files are on there, you can print from with no PC attached.
