I am curious. I like to know how things work. For the curious, this Instructable will try to explain some of the Arduino electronics. I suspect many people have built Arduino projects but couldn’t get them to work. I hope to provide some knowledge and skills to help fix hardware problems such as wiring errors […]

When I started to deal with Chinese electronics suppliers from websites like Alibaba, Aliexpressand Taobao, I discovered that there are huge amount of undiscovered tools from the Chinese market. They are not easily discovered, maybe due to the Chinese language barrier, especially when we deal with a Chinese website like Taobao or maybe because most of us are

NanoEngineers” research group at Iowa University have been devoting efforts to use graphene and its amazing properties in their sensors and other technologies. Graphene has many extraordinary properties. It is about 100 times stronger than the strongest steel. It conducts heat and electricity efficiently and is nearly transparent. Inspired by some recent projects about using inkjet printers to print

If you have high-powered LEDS, or a power supply, or are trying to control larger motors, you have to get a lot of heat out of your circuit boards. The classic way to dissipate heat is to bolt your power transistor to an aluminum heat sink. That is a slow, messy, and expensive proposition, especially if you need

All electronics require certain components in order to work. In robots, there needs to be a motor as well as a circuit board to send the electronic device programmed information. In computers, there are motherboards, hard drives, processors, and of course, circuit boards. Almost anyone can learn how to put together an electronic device from

The miniSpartan3 is our new, low cost, tiny, FPGA kit. It starts at just $29, and there is a more powerful FPGA chip available for $39. Features: The Spartan 3A XC3A50 FPGA ($29), or the Spartan 3A XC3A200 FPGA ($39) from Xilinx. An on-board USB JTAG Programmer to power and program your FPGA. An on board USB to Serial
A switch is a fundamental part of most electrical and mechanical devices; mechanical switches can be used to select gears in a car’s transmission or used to unlock a door; electrical switches can turn the lights in a room on and off; semiconductor uses to route logic signals within a circuit or control bigger devices.

Orlando Hoilett from Calvary Engineering LLC designed a versatile Li-Po battery breadboard power supply and wrote an Instructables on it. This power supply outputs 3.3V to the breadboard and takes input from a single-cell LiPo battery. The breadboard power supply also has the ability to charge the battery without needing to separate it from the circuit board. More importantly, this

If you’ve recently found yourself spending too much time looking at memes on your phone, or you’ve noticed you are becoming unnervingly familiar with Netflix’s back catalogue of obscure conspiracy theory documentaries, it might be time to find a new hobby. Preferably one that’s not going to rot your brain. And if you happen to have an

Recently the hobbyist market has seen the appearance of the Air602 low-cost ARM WiFi module. This module might be a potential competitor of ESP8266, another low-cost powerful WiFi module, that took the electronics hobbyists by storm long ago and is still extremely popular. But what’s more interesting about the Air602 module is the usage of a completely
