Today I will show a very simple ionization chamber that can detect radioactivity. I was able to detect with it ionizing radiation from a smoke detector (Am241 isotope). It’s also immune to electromagnetic interference (EMI) due to a good shielding. This device doesn’t explicitly use any power supply. It’s connected to a multimeter set to measure resistance, […]
Joulescope™ enables designers, engineers, and makers to quickly and easily optimize the energy consumption and battery life of a target device. Joulescope is designed to automatically handle wide current ranges and rapid changes in energy consumption, while allowing the target device to run normally. Jetperch LLC writes: Measuring energy consumption during product development is crucial,

Keysight 34465A & 34470A DMMs offer unprecedented levels of accuracy, speed and resolution. They can measure very low current down to a 1 μA range, enabling their use on very low power devices. The ability to auto-calibrate during the measurement allows the 34465A and 34470A to maintain a calibrated measurement while the instrument may be

Low power consumption Better Amperes display resolution while using low value drop resistor. Much smaller PCB size, only 5cm x 5cm. Still no SMD components. Easy calibration, only one voltage adjust and one ampere adjust preset, no voltage out detection. Voltage supplied by my 12Volt benchtop PSU(The resistor at output terminal is disconnected. The 10Ohm

Intro I got a Peaktech 6225A power supply to power some things, as it seemed like a good deal, going beyond what one might find normally in these types of supplies: more display resolution and supposedly, lower noise. For this price, this supply is a good deal compared to other similar ones on the market.

This is a little project I made recently, I call it USB A to micro USB bridge and it does what the name says: it’s just a bridge between the USB A female connector and the female micro USB. In the middle there is a DIL pin header that allows you to connect or disconnected

A multimeter is a brilliant instrument that combines several functions – typically, measuring voltage, current and resistance. Although both digital and analogue multimeters exist, the vast majority in use today are digital and hence this guide will use images of a digital multimeter, or DMM, to illustrate various steps. Getting Started With a Multimeter To
