The Meter 2014-12-01 21:12:00 Been awhile since I posted anything here, so I thought I’d use this post to give some more detail on a project I just completed. The whole idea was to create a giant meter to show website response time almost like a speedometer would. The result is something that’s both fun […]
The SiT5003 is the most flexible LVCMOS/LVTTL/HCMOS compatible, ultra-stable MEMS VCTCXO (Voltage Controlled, Temperature Compensated Oscillator) solution in the market. This device supports any combination of the following features: frequency (1 – 80MHz), voltage (1.8V, 2.5V-3.3V), stability (±0.5PPM), pull range (±12.5PPM to ±50PPM) and 4-pin packages (3225, 5032, 7050). It provides superior shock and vibration

This Design Idea demonstrates a new method of driving six LEDs with only two I/O lines from a microcontroller, and so is particularly suitable for any pin-limited chip. It uses a pair of I/O lines combined with a pair of complementary bipolar transistors.More than one LED can appear to be lit by multiplexing. A previous
Wideband communication systems usually require an ultra-low noise regulator to power the VCOs and PLLs. The regulator must also be able to reject any ripple presented at its input. In a typical system, an ac input is converted to an isolated dc supply rail, –48-V, for example. This rail is then converted to an isolated

Trying to figure out what kind of cool stuff you can create with a 3D printer it’s not always easy if you just look to a magazine talking about it or hosting an advertising page: to fully understand what a 3D printer can do for you, you need to start printing. No coincidence that those who can “get

Introduction Flyback converters are widely used in isolated DC/DC applications because of their relative simplicity and low cost compared to alternative isolated topologies. Even so, designing a traditional flyback is not easy—the transformer requires careful design, and loop compensation is complicated by the well known right-half plane (RHP) zero and the propagation delay of the
Long term reliable contact without interference, creaking and hum, moreover in a beautiful coat – these are the Neutrik / Rean connectors. Connectors have in general one interesting feature – there are many similar or almost the same connectors on the market. Audio connectors are not exception in this. Even though they look the same,

An black and white monitor needs to improve and repair from about 1990-th. The repair of device was not difficult but it caused troubles for the testing and setting of the monitor. We have a pattern TV generator, but this instrument are produce on the composite video signal for monitor. Unfortunately this monitor is demand
Researchers Superconduct at 140 Degrees Lasers align lattice for pulses of superconductivity R. Colin Johnson 12/15/2014 07:15 PM EST 8 comments PORTLAND, Ore. — Superconductors are heating up. A group of international scientists working with the National Accelerator Laboratory in Menlo Park, Calif., have discovered lasers that can create conditions for superconductivity at temperatures as
