A DIY FLUXGATE MAGNETOMETER BASED CURRENT PROBE

Introduction Current measurement can be really awkward when working with circuits. Voltage measurements are (usually) straightforward, but when it comes to current measurements the story is different. One typical approach is to insert a known resistance by breaking the circuit, and then measuring the voltage across it. This is difficult if one end of the

Teardown of an Array 3711A 300W DC electronic load

I have made many electronic loads in the past. For instance this simple harddrive cooler housed small dummy load, this more sophisticated constant current/constant programmable load and this heavy-duty electronic load that is capable of sinking over 1kW under peak load. In this blog post though, I am going to take a look inside an

ICNexus’s SBC3100 Runs Linux On Rockchip RK3399 SoC

Taiwan-based ICNexus’ latest entry with Rockchip RK3399 SoC, SBC3100 joins the growing list of high-end SBCs. It features the high-end SoC to provide an extensive feature list. However, it is not publicly priced and appears to be a proprietary product, such as Aaeon’s Pico-ITX based RICO-3399. ICNexus announced the SBC3100 back in 2017, the SBC3100 was showcased at

Spansion DC-to-DC power management IC supplies three power channels

Spansion is sampling its S6AP412A series of multi-channel DC-to-DC power management ICs (PMICs) and expects to have production volumes available in September starting at $3.60 in volumes of 1,500 units. The S6AP412A series — an expansion of the Spansion MB39C031 family of DC-to-DC buck-converter, programmable PMICs — supplies three channels of power on a single

Raspberry PI L298N Dual H Bridge DC Motor

There are not any examples that I could find that properly show how to get a simple DC motor working with RaspberryPI. This is a simple tutorial for “How to make a motor turn.” Robots, wheels, conveyors, and all sorts of stuff can be made to move using simple Raspberry Code and really inexpensive RC-racer

Low cost DC millivolt source

DC millivolt sources are often used for thermocouple simulations, DMM, ADC and analog circuit calibrations and fault findings, etc. Most of the DC millivolt circuits are based on expensive (and sometimes hard to find) operation amplifier like OP7, LT1077, etc. In this article we introduce low cost DC millivolt source based on commonly available LM308
