Geiger counters are devices used to detect radioactive emissions, most commonly beta particles and gamma rays. The counter consists of a tube filled with an inert gas that becomes conductive of electricity when it is impacted by a high-energy particle. The Geiger–Müller tube or G–M...

The DIPFORTy1 is a powerful Xilinx based FPGA board with small form factor and many programmable I/Os. It is popular for its high performance at most competitive price. Introduction: The TE0722 is based on the Xilinx Zynq-7000, a System on Chip. It contains a FPGA and a Dual Core...

The $5 Raspberry Pi Zero is a standalone computer that can be embedded in various applications, but maybe now it is time to add some extra features. It comes with a USB OTG port, meaning it can function as a USB device rather than a USB host. Thus, it can become a serial device with...

Sometimes the float valve of a water tank may not work properly causing water to overflow and spread across the floor. Peter Jennings faced this problem in his storage area, and he had developed an alarm device to notify him when the water exceeds its normal range. Peter’s project...

Infineon Technologies' Infineon Designer, introduced at the 2016 electronica trade fair, is presented as the first online prototyping engine combining analogue and digital simulation functionalities in an internet application. By Graham Prophet@ edn.com: Requiring a web browser only,...

Configurable as quad, triple, dual or single output, the LTM4643 quad output step-down µModule [micromodule] (power module) regulator deliver, respectively, 12A, 6A & 6A or 9A & 3A, or 4 x 3A from a 9 x 15 x 1.82 mm ultrathin LGA package. by Graham Prophet @ edn.com: This...

Ed Mallon has details on his DIY ProMini data logger: Typical pro-mini loggers built with this design sleep at 0.25mA, before extra sensors are added. At that current draw, the logger should deliver approximately six months of operation on three brand new AA batteries with a 15min...

Lucky Resistor has build a PWM fan controller using Arduino and DHT22 sesnsors. The fan controller described on this project page, controls one or more PWM controlled 12V PC fans. It uses the input from two precise DHT22 based temperature sensors. The MCU is an Arduino Uno, which is...
