Occupied

A toilet queueing app for serious poopers. Uses resin.io, firebase and twilio to notify people when the toilet is open – runs on the RPI. I just moved into a three story house with 6 people and 1 toilet. Running down stairs every morning to find the bathroom occupied became a common annoyance for everyone …

Researchers develop thin sensor to detect magnetic fields down to 200nT

A team of researchers from Germany and Argentina have devised an ultra-thin planar Hall effect (PHE) sensor capable of detecting very faint magnetic fields even when flexed or wrapped around a wire. by Julien Happich @ www.eenewsembedded.com In a paper titled “Highly compliant planar Hall effect sensor with sub 200 nT sensitivity” published in Nature’s npj …

Dual-Channel Quadrature Hall-Effect Bipolar Switch Module for Magnetic Encoder

The A1230 is a dual-channel, bipolar switch with two Hall-effect sensing elements, each providing a separate digital output for speed and direction signal processing capability. The Hall elements are photo lithographically aligned to better than 1 µm. maintaining accurate mechanical location between the two active Hall elements eliminates the major manufacturing hurdle encountered in fine-pitch …

Remaking MSR206 RS232 magnetic card reader to USB

As you might have noticed, sometimes I work as freelancer in electronics =) It applies not only to fixing PC electronics and mobile phones, but also to repairing, modifying and designing my own solutions in consumer electronics. One of the projects I worked on yesterday is modifying MSR-206 magnetic card reader to replace RS232 port …

Honeywell changes magnetic sensor design, forever

Honeywell Sensing and Control has designed a position sensor IC which combines the sensitivity of an anisotropic magnetoresistive (AMR) sensor with the low power operation of a Reed switch. The range of magnetoresistive sensor ICs is called Nanopower reflecting a typical power consumption of 360nA. This is a ten-fold reduction in power consumption on previous …
