Introduction For a Nottingham Hackspace project, I was asked if I could measure the RPM of a motor. “Sure!”, I said. What was really needed was quickly bodging together a beam-break circuit and connecting it to an oscilloscope. This would have taken a couple of hours at the most. But like a proper software engineer,
Product Description The ESD7004 transient voltage suppressor is designed to protect high speed data lines from ESD. Ultra-low capacitance and low ESD clamping voltage make this device an ideal solution for protecting voltage sensitive high speed data lines. The flow-through style package allows for easy PCB layout and matched trace lengths necessary to maintain consistent

Description The LTM®9011-14/LTM9010-14/LTM9009-14 are 8-channel, simultaneous sampling 14-bit A/D converters designed for digitizing high frequency, wide dynamic range signals. AC performance includes 73.1dB SNR and 88dB spurious free dynamic range (SFDR). Low power consumption per channel reduces heat in high channel count applications. Integrated bypass capacitance and flow-through pinout reduces overall board space requirements. DC

Hi everyone, Here is my last project, a tiny waveform generator based on my previous project and some components: – An AD9834 (DDS chip with sinus/triangle output) – 2 x AD5310 (10bit DAC: one for the Vpp control, another one the offset control) – 3 x LM7171 (Fast OPA) – 3 x LT1616 (switching regulator:

I had some spare 4-digit 7-segment LED displays and some AT90USB82s, and I’d always intended to do something with them. This was probably the easiest thing! It’s just the AT90 driving the display, with a(t least) 4 wires controlling it: Vcc, GND, MOSI and SCK. (I haven’t written the code yet, but my plan is

This clock is based largely on Alan’s code and circuit with a few changes. I purchased a kit of parts for the main board from Alan’s site. I have used three voltmeters and mounted them on a wooden plinth with a clear Perspex cover to give the clock an industrial look. I have modified Alan’s

Perhaps the most frequently used rechargeable batteries on the market nowadays – Lithium-Polymer (Li-Po) can be found also in our offer. From the beginning of electronics, the world searches for an “ideal” rechargeable battery. So far such a battery doesn´t exist (maybe supercapacitors in the future), but Li-Po (Li-Pol) cells are quite near to an

ElecFreaks will launch a multi-axis unmanned helicopter series: ELF. As the name suggests, this series will be surprisingly tiny. Aimed to design a very compact, portable, able to fly in any place multi-axis helicopter, we will use smart phones app (must support Bluetooth 4.0) instead of remote control. Smaller also means more security and therefore

Farnell and Analog Devices are to co-host a webcast entitled ‘Simplifying System Designs Requiring Isolated Data and Isolated Power’ on Nov 30 4-5 pm CET. To register “Our webcast series is just one of the many ways Farnell is seeking to support customers in producing world-class designs,” said Richard Curtin, Farnell’s head of semiconductors, passives and optoelectronics products.

Since when white light emitting high brightness LED are available, the handover from traditional lighting bulbs to the solid-state lighting has become irreversible: LEDs have an efficiency (expressed in lumens/watt) higher than that of almost all the traditional lamps (except, at the moment, the large sodium vapor lamps used for street lighting, unusable in closed
