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 […]
Most of us who work with electronics know the name of Texas Instruments (TI) as a manufacturer of several important digital and analogue ICs as well as fancy sophisticated scientific calculators. However many people don’t know that TI is also a manufacturer of some of industry’s best microcontrollers. TI’s portfolio of micros is pretty large.
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

A microchip containing 1,000 independent programmable processors has been designed by a team at the University of California, Davis, Department of Electrical and Computer Engineering. The energy-efficient “KiloCore” chip has a maximum computation rate of 1.78 trillion instructions per second and contains 621 million transistors. The KiloCore was presented at the 2016 Symposium on VLSI
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
