1907, a British Henry Joseph round discovered that when an electric current is applied to the inorganic materials, it could emit light.

Since then, people start the study of the LED. And through the development of many years, not only LED burst into various brilliance in the lighting field but also applied in various fields. And nowadays our awesome makers use these tiny light bulbs into the various projects. And it’s all start from the human instinct of pursuit of light. This article will show 14 different kinds of LED projects. You can also watch the video version below.

1.POV Flex LED Version1

Carl’s first version of FlexLED. It can light 3 colors, green, yellow and red. The Hyper Red source color devices are made with AlGalnP on GaAs substrate Light Emitting Diode. The Super Bright Yellow device is made with AlGalnO(on GaAs substrate) light emitting diode chip. The Green source color devices are made with InGaN on Sapphire Light Emitting Diode.

Holographic FlexLED

It’s an upgraded version of the POV Flex LED with more richer display content. He even program it to show a holographic heart as a valentine gift.

2.LED Mask with Arduino and Mic

Inspired by the situation of wearing masks nowadays, Jonathan made a mankind-friendly project in which the LED will change the form when you are speaking, and the light will turn to red if you speak louder.

3. LED Ball

This attractive LED Ball is made by Hari Wiguna. The unique of this project is that he put the LED not on the surface but on the edge of the PCB. And then joint these arc-shaped PCBs into a 3D sphere.

4. PCB Pyramid

A delicate artwork — — PCB Pyramid. The project includes some ws2812b LEDs and an ESP8266 to control them over wifi using the Blynk IoT platform.

5. 7 Segments RGB Display

Using NodeMCU and WS2812b LEDs, @Electro Point create a Addressable 7 Segments RGB Display. The displays are individually addressable that means you need only one data line to control as many displays as you want. He made a custom PCB which has 2 LEDs per segment. So that’s total of 14 LEDs per digit.

6.POV Fidget Spinner

Handsome Maker Sean’s POV Fidget Spinner, after the accumulation of several projects of fidget spinners, he made this shining one.

7.Holographic Clock

Propeller Holographic Clock, it can show specfic texts, numbers and patterns.

8.4X4X4 LED Cude

9. 8X8X8 LED Cude

10. Music Reactive Multicolor LED Light

11. Police LED

12. Ping Pong LED Wall

13. Solar Panel Using LED

Generate Gerber files in Eagle

Image
1. Generating Drill Files To create a Gerber file in Eagle, you should run the drillcfg command first: File -->Run ULP -->  the pop-up "Drill Configuration" dialog box and click the "OK" button to generate the corresponding drill configuration file. 2. Generating Gerber Files Open the .brd file, and then  the "File" menu to open the "CAM Processor" dialog box. In the "CAM Processor" dialog box, select "File" -> "Open" -> "Job ..." command, open the "Open CAM Job" dialog box, select the "excellentone.cam" and click "Open" button. After loading it, click the "Process Job" command to generate the corresponding drill file: In the "CAM Processor" dialog box, select "File" -> "Open" -> "Job ..." command, open the "Open CAM Job" dialog box, select one of the "gerb274x.c...

A Powerful 30A DC Motor Driver using Power Mosfets [PWM Controlled, Half Bridge]

Image
By Hesam Moshiri, Anson Bao DC motors are everywhere, from hobby applications to robotics and industrial areas. Therefore there is wide usage and request for suitable and powerful DC motor drivers. In this article, we will learn to build one. You can control it using a Microcontroller, an Arduino, a Raspberry Pi or even a standalone PWM generator chip. By using a proper heatsink and cooling methods, this circuit can handle currents up to 30A. [1]: Circuit Analysis The heart of the circuit is an IR2104 MOSFET driver chip [1]. It is a popular and applicable MOSFET driver IC. The schematic diagram of the circuit demonstrated in figure-1.  Figure-1 The schematic diagram of the powerful DC motor driver According to the IR2104 datasheet [1]: ”The IR2104(S) are high voltage, high-speed power MOSFET and IGBT drivers with dependent high and low side referenced output channels. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic constructio...

Generate gerber file from Altium

Image
Step1: The work before generate the Gerber file  Before generate Gerber file, you need to set criteria, but for most of PCB designers, these are not necessarily. The following is a brief explanation of these settings, You can also ignore these setting when generate Gerber file.  1. The settings of PCB shape and size, generally are mechanic1,2 layers. 2. Before generate the Gerber file, the preprocessed of PCB file. The preprocessed include: a. Add break away rails of PCB b. Add stamp hole. c. Add the machine jack. d. Add mouting hole e. Add drilling descript_ion. f. Add dimension descript_ion. g. Set the origin Step2: Generate Gerber file 1. Open the Gerber Files. Step1: The work before generate the Gerber file  Before generate Gerber file, you need to set criteria, but for most of PCB designers, these are not necessarily. The following is a brief explanation of these settings, You can also ignore these setting when generate Gerber file.  1...
