Analogue Sensors – Calculate the Nonlinearity Introduced by a Load or Pull Down Resistor
Tecwyn Twmffat @ instructables.com discuss about the notlinearity introduced by adding a pull down resistor and why you may get unpredictable readings from your ADC. For many years I found that I would get strange, unpredictable, readings from my sensor related projects at the...

Troubleshooting a 32kHz Crystal Oscillator
How to Actually Make it Oscillate? Now for an oscillator to work, we need an amplifier with a gain of greater than 1, and a phase shift of 360 degrees to get positive feedback. First problem – the transistor was saturated, with Vc stuck near 0V. For an oscillator to start noise...

Ultra Low-Power (35nA!) Programmable Timer using TI TPL5111
Ultra Low-Power (35nA!) Programmable Timer using TI TPL5111. Imagine a system for example that has to work from a small coin cell for 5-10 years. TPL5111 solves a typical problem in low power wireless systems- things need to be off most of the time, and wake up periodically to...

Review: ScanaQuad – a super-small logic analyzer
Harry Baggen @ elektormagazine.com reviews the ScanaQuad, a new series of tiny 4 channel logic analyzers. The ScanaQuad series consists of four modules (SQ25, SQ50, SQ100 and SQ200), which mainly differ in the sampling rate. The French company Ikalogic has been making logic analyzers...
