Today we have repaired a LCD Monitor Hanns G HQ191D with model no: HSG1018, came with symptoms that will not to turn on. I opened it and saw that the electrolyte(C907-100uF/400v) cracked, I checked all the primary power supply and I found that the bridge rectifier is in short circuit, and of course (F901-2.5A) fuse [...]

Laptop batteries can be repaired but such work only makes economical sense for smaller operators.The success rate varies with battery type.One must remember that the ‘smart’ battery consists of two parts, the chemical cells and the digital circuit.In some cases, the chemical part can be fully restored but the fuel gauge may become inaccurate or [...]

I want to say that the inverter board did not roll CCFL transformer, so I could not find the original [...]

Today we made a new project SPI Flash Programmer. I needed this programmer to read  the contents of 25L1005 on a LCD Monitor. The circuit is connected to the PC via parallel port and he have external power supply. This circuit contains a few components listed below. IC1 : 8 Pin Machine Tooled IC Socket [...]

DorkbotPDX has made good project, Mykle called him for RGB LED lighting help and he helped Mykle for his lightbar. The basic idea was run all 3 LEDs in series. He ordered a few ASMT-MT00′s and other parts, and came up with a somewhat unconventional design.The ASMT-MT00 nicely provides each LED separately on 6 pins, [...]

Chris from pyroelectro  has made AV Test Box. This Box  includes displaying an 800×600 VGA test pattern as well as generating sound signals for testing audio systems. This video will you show what you can expect from this AV test box like the one built in this project and will show how quickly whether or [...]

Nice project from Petar , he send me some photos of his UV Box. This UV LED Exposure Box was published in the magazine Emiter, and here’s what the author says on this project.

Several years after they appeared on the market, set as lights in my home.I noticed that quite often it burns faster electronics, lamps than themselves.I made a few holes on the body, for better cooling.Lamps with additional cooling, had more life. Then I started to combine.Correctly electronics from lamp which blighted associate with lamp where [...]

I needed this adapter to read the contents of EPROM on a Panasonic phone, and so I found this link here and built this adapter. Download PCB Board in PDF:  SOIC to Dil 8 Adapter

Is it possible to begin a new era of cheap electronics…If this is true, the development of a new production method could make it possible to manufacture superior-quality, flexible, electronic products at an extremely affordable price. According to Aalto University in Finland, Professor Yutaka Ohno of the University of Nagoya in Japan and Professor Esko [...]
