I’ve had a CNC mill for a few years now, and while many homemade CNC mills use EasyDriver or Pololu, mine came with a sturdy, generic TB6560 controller board. For those unfamiliar, boards like this are interfaced using an old fashioned LPT parallel port, which was initially an annoyance, but quickly became impractical and a

Continuous monitoring of heart activity permits measurement of heart rate variability (HRV), a basic parameter of heart health and other diseases. This Design Idea is a new design of pulse oximetry that excels in its simplicity and functionality. Due to its capabilities, it can be used as a standalone device, able to monitor heart rate

I was looking at a low cost way to build a 10Mhz frequency for my electronics lab. I had a few options that I could pursue, these were… GPS Disciplined Crystal Oscillator (GPSDO) Rubidium atomic standard (RbXO) Caesium atomic Standard Oven Controlled Crystal Oscillator (OCXO) So to make a choice on what I should use

A flexible display incorporating graphene in its pixels’ electronics has been successfully demonstrated by the Cambridge Graphene Centre and Plastic Logic, the first time graphene has been used in a transistor-based flexible device. The partnership between the two organisations combines the graphene expertise of the Cambridge Graphene Centre (CGC), with the transistor and display processing

Fifteen types, three sizes and three strong features – these are the new DIN-rail power supplies Uno Power from company Phoenix Contact. To be on the top in a segment of power supplies nowadays means above all high efficiency, low power consumption without a load (Standby) and compact dimensions. New series Uno Power from company

Today we’ll explain how to exploit the potential of Arduino as a programmable logic controller, connecting it to appropriate interfaces for I/O. The PLC (Programmable Logic Controller) has been and still is the basic component of the industrial automation world. The Industrial application made the PLC systems being very expensive, both to buy and repair,

f an atom gets excited in a laboratory, does it make a sound? Turns out that it absolutely does, albeit it’s the softest sound that scientists say is physically possible. Researchers at Columbia University and Sweden’s Chalmers University of Technology say that they have, for the first time, “captured” the sound a single atom makes when it

Standard optocoupler speed is limited mainly by the relatively slow response of the phototransistor. This Design Idea adds components to the LED drive side to speed things up. R1 is the original LED resistor, as used before the extra circuitry was added. Here however, its value can be higher, as the turn-on speed is determined
