Panasonic has launched its first 3D Ready television at an event in Munich, Germany.
The VT20 Plasma 3D Ready TV will come with the choice of two screen sizes, fifty (50VT20) and sixty five (65VT20) inches.
It will be the first Panasonic TV capable of displaying of 3D images. This TV 50VT20 will cost around £2,000 and [...]

This video will show you how to etch a circuit board. Nice explanation.

OmniVision today Introduces  a new 1/4-inch, 5-megapixel RAW CMOS image sensor based on its 1.4-micron OmniBSI™ backside illumination (BSI) technology. The OV5647 is a cost-effective, high-performance mobile imaging solution, offering the performance and size benefits of BSI technology while allowing mobile phone designs to utilize existing baseband or applications processors for image processing functions. OmniVision’s [...]

USB – RS232 converter, uses only Tx and Rx lines, with selectable 2400, 9600, or 38400bps. PCB projected to fit in old mobilephone cable, most of parts is surface-mounted.

This is a small frequency counter with a cheap PIC microcontroller and a few seven-segment LED digits. The main features of the frequency counter are:
*   frequency range 1 Hz … 50 MHz (prototype worked up to 60 MHz but this exceeds the PIC’s timing specifications)
* four or five digits resolution (display for example x.xxx kHz, [...]

This is a simple capacitance meter which can measure capacitance value easy. There are some measurement methods for capacitance, at one time the capacitance was measured with a impedance bridge or a dip meter. Recently typical capacitance meters can measure capacitance and some additional characteristics from current vector by applying AC voltage to the Cx.

In early 2005, NEC launched small pin count microcontrollers like PIC/AVR based on 78K0S architecture. The 78K architecture has a register set similar to i8085 and additional bit operation instructions. It can be saied that a stale architecture but the memory space is plain compared to PIC/AVR. There are various devices with application specific peripherals [...]

This is a simple circuit to connect your VGA graphics card to your TV. The advantage of using RGB over S-Video is superior contrast and clarity. The schematic of this circuit is taken from Tomi Engdahl’s site. The circuit basically XORs together your horizontal and vertical synchronization signals to create a composite sync output, and [...]

This is a simple circuit which can detect when you touch a sensor connected to one of the sensor inputs. It can be used to add a touch switch to your computer for example. It uses an AVR micro controller, the AT90S2313.
