We have for you a measuring device able to measure even small resistance with 0.01 Ohm resolution. UT602 is exactly that device, which you may have missed at development of devices operating with higher currents, where every resistance (lead, connector, joint,…) acts negatively,...

by Wichit Sirichote: This is the 2nd version of Thermistor Thermometer Project done by another group of my student. The 1st version having 4-digit 7-segment LED shows the use of simple display device. For applications that needs text display, this LCD version is more suitable and...

by Graham Prophet @ edn-europe.com: LTC3265 is a high voltage, highly integrated, low noise dual output power supply IC which takes a single positive input supply (VIN_P) and generates low noise bipolar rails up to ±2•VIN_P without any inductors. High voltage boost and inverting...

The major component of this circuit is Microchip's SST89E54RDA-40-C-PIE, which is a pin-for-pin compatible with typical 8051 microcontroller devices. It has a built-in timer used to produce accurate time delay. The light emitting diode (LED) is connected through the 330Ω resistor to...

by Susan Nordyk @ edn.com: The ISL94203 battery-pack monitor IC from Intersil monitors, protects, and cell-balances three- to eight-cell rechargeable battery packs, supporting Li-ion CoO2, Li-ion Mn2O4, and Li-ion FePO4 chemistries. Its internal state machine has five preprogrammed...

blackmesalabs.wordpress.com has build a video system for Arduino boards: This post describes Mesa-Video, a low cost, low power, small size and fully Open Source Hardware and Software solution for providing 800×600 digital video for Arduino ( and other ) microcontrollers. Mesa-Video...

Noriaki Mitsunaga has build an Arduino Oscilloscope using minimum parts. He writes: I have created a simple Arduino Oscilloscope as above picture shows. Here is its summary. You can build your own! Arduino Oscilloscope -...

Zak's Electronics Blog published a new library and breakout board for MCP2221 USB to UART interface IC: This is a library for interfacing with the HID features of the MCP2221 USB to UART and I2C/SMBus serial converter from Microchip. The converter includes 4 GPIO pins, 3x 10-bit...
