DIY Colorful Heart Shape LED Flashing Kit Feature: Supply voltage: 4-5.5V Dimensions: 75 x 85mm Principle: This kit contains 32 LED arranged in a heart-shaped pattern, driven by the IO port (active low); Write program control IO port to high and low level, the LED lights off or on, forming a variety of patterns effects, especially when used at night, very dynamic. Circuit is divided into three parts: the minimum system circuits, power circuits, and heart-shaped lamp circuit; Connect power 4-5.5V, press S1 latch switch (this circuit design two power interface, easy to operate), the microcontroller begin to work, 32 IO ports each string limiting resistor and LED lights connected to VCC, which LED lights which IO port is low, which is fully controlled by the program; This kit has been programmed, after assembled can be connected to display all kinds of tricks. Installation Notes: Pay attention to polarity when installing light-emitting diodes and electrolytic capacitors, long legs is positive. Note the U port direction when you install the chip seat, the positive and negative power supply can not be wrong, otherwise it will burn the chip. The middle of plug socket is positive, the outside is negative. Schematic: Click to open Package included: 1 x Heart Shape LED Flashing Kit  

DIY Radio 40M CW Shortwave Transmitter Kit Receiver 7.023-7.026MHz Brief introduction: This kit is a classic low-power transceivers. This is a very small volume of simple 40 meter band micro-power amplitude telegraph transceiver uses a 9V square battery. The reception is good, highly readable code, is the entry of the most junior amateur radio choice! Technical parameters: Power supply: DC 9V-14V Antenna: 50 ohm, unbalanced Receive quiescent current: 10mA @ 9V Transmit power: 0.8W @ 9V, 1.2W @ 12V Frequency range: launch 7.023MHz, receive 7.023-7.026MHz (7.023MHz crystal) Mode: CW Shell selection and installation: Beautiful metal case not only for item considerably, and can effectively shield nearby interference. There are many optional shell, for example, metal cans, aluminum boxes, medical elongated aluminum box and so on. Select the box in time to pay attention as easy to open, because the battery ran out and need replacing. Recommendations: The confidential achieve better results, set the antenna performance can not be less than the full length of the horizontal half-wave dipole antenna, in conjunction with the use of Simple Barron, antennas should be kept away from sources of interference, such as fluorescent lights, computer monitors, switching power supplies and other equipment as much as possible with the coaxial cable as feeders to reduce possible interference received, as a small selection of the broadcast interference morning or late at night listening to get the best results listen to SSB and CW signals signal. Note: We don't supply any manuals please note about this before you order it. Package included: 1 x Shortwave Transmitter Receiver 7.023-7.026MHz QRP Pixie Kit

Technical Parameters: Product Name: Modified sine wave inverter change pure sine wave rear plate Input voltage: DC380V. Input voltage: AC16V. Output voltage: AC220V. Output frequency: 50 / 60HZ (adjustable) Output waveform: pure sine wave. PCB Specifications: 165X100X50MM. 2000W using power tube: 4 / 47N60 Instructions: Product are modified wave inverter charge sine wave inverter, can make modified wave inverter 2000W, etc..., as modified pure sine wave inverter.First, remove the power tube after correction inverter, and then look at the correction inverter have how many transformers, look at the transformer secondary circuit is connected in parallel or in series, and then add the transformer parameters, modified wave transformer secondary is parallel, In each transformer secondary plus 16 laps. The secondary of the modified transformer is a series type, plus 8 laps per transformer secondary. Then in the correction transformer which transformer one empty foot plus a small voltage parameter, the small voltage parameters using 0.6 copper wire, in the transformer inside around: 5 laps, the small voltage is linked AC: 16V position. (Note: Do not open the magnetic ring when the add transformer with the parameters) After the addition of transformer parameters, we must correct the modified wave inverter high voltage capacitors in exchange for 220UF / 450V, Remember: modified wave inverter high-voltage capacitor has a positive feedback Resistance, the resistance is a few hundred K, but also need to change a large resistance, or the voltage will not rise. After testing the voltage of high-voltage capacitor (positive/negative) voltage is DC380V, the test voltage is normal, the use of cable to the sine wave after the board, after the board output voltage: AC220V / 50HZ, the output waveform: pure sine wave. Package included: 1 x DIY 2000W Pure Sine Wave Inverter Rear Plate Kit

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.
