Qingdao Hantek Electronic Co., Ltd. Électronique. All Electronics $1 Scrounging Board. When I was shopping for some goodies at All Electronics I came across a circuit card they were selling for $1.
The description indicated that the board included two voltage regulators, a crystal and assorted parts. I like to scrounge and look up the parts used in consumer electronics so I purchased one of these just to scrounge. It’s like a grab bag of parts that engineers really use… In this short article I provide some high-resolution pictures of the board using the PCB scanning method described in this previous article. I remove parts using the scrounging methods described here, and I list the parts I thought were worth removing, with data sheet links. This picture shows the component side of the board. VGA to workstation monitor FAQ.
Making the connection to VGA card Connecting VGA card to various monitors Questions and answers What tools are needed to do the connection ?
Ultra-High Fidelity High Power Amplifier Reference Design. Ultra-High Fidelity High Power Amplifier Reference Design. Converting an Inkjet Printer to Print PCBs. Recently one of my focuses has been to find a way to make the PCB (Printed Circuit Board) creation process easier.
I like being able to design something based on what I want in a circuit and just making it myself on the random weekend. While the toner transfer method has been my go to in the past it’s just not nearly as consistent as I would like it to be. The specific pressure of the iron and timing both make it a hit or miss approach. Nouveaux circuits. Constant current source with LM317.

High Voltage Converter: 90V From 1.5V The circuit shows one way of obtaining a voltage of 90V from a 1.5V battery supply. Heat Sensitive Switch At the heart of this heat-sensitive switch is IC LM35 (IC1), which is a linear temperature sensor and linear temperature-to-voltage converter circuit.

Electric Imp. Description: We know what you're thinking, "What's the big deal?
Looks like an SD card... " Well this is no SD card! The Electric Imp is a WiFi enabled development platform powered by a Cortex-M3 processor core. "Really? " Yup. In essence, the Imp provides an easy, integrated way to connect almost any hardware device both to other devices and to internet services. How to make a XY-plotter with Makeblock. iCharger 3010B 1000W 10s Balance/Charger.
I bought two.
Been running one 3010B for several months with great results. I typically charge six, 6S, 4000mAh packs at a time using parallel charging and balance cables. The charges are at full rated capacity of 30A (750W). The 3010B barely gets warm. Using two 3010B chargers, I can charge up all 12 packs in about 40-43 minutes. Printing Circuits with Conductive Paint. The circuit is pretty simple, it centers around a 555 timer IC.
The 555 timer is wired up in astable mode, meaning that it will be outputting a continuous square wave, with a frequency dependent on the resistance between the two pins labelled "POT" in the diagram above. The only extra components needed are a 1kOhm resistor and a 0.01uF capacitor. The circuit is powered by a single 9V battery, connected at the ground and 9V pins. A speaker is connected to the ground and output pin (pin 3) of the 555. Relay Basics. Relay Basics by: Andrew Krause Relays are one of the oldest, simplest, and yet, easiest and most useful devices.
Before the advent of the mass produced transistor, computers were made from either relays or vacuum tubes, or both. A relay, quite simply, is a small machine consisting of an electromagnet (coil), a switch, and a spring. Electroengine. Links. General Few designers spend time pondering the traits of resistors, capacitors, or other simple passive components.
Determine the necessary nominal value, tolerance, and temperature coefficient for each instance in your circuit, and you're pretty much done. Consider the nonelectrical variables like package and pricing, and you're a certifiable good corporate citizen. When it comes to the active components, there are also many other things to consider. Resistors Resistors are passive electronic components used extensively on the circuit boards ofelectronic equipment. Most importans characteristics of resistor are the resistance, tolerance of resistance and the power handling capacity. Most small general purpose resistors have power handling capacity ofaround 0.25W. Kituri de aparate de masura si control electrice.
