APEXEL ET8103 IS AN INTELLIGENT DIGITAL MULTIMETER WITH NO KNOB

A digital multimeter is an electronics measurement tool which is a necessary and powerful tool for every hacker, engineer, and maker. It can be used as a voltmeter, ohmmeter, ammeter, continuity meter, and some even offer more features than this. At the hand of a creative hacker, it might just be the only debugging or measurement tool you might need if you lay your hands on the right one. With a multimeter, ...

DC MOTOR INTERFACING WITH 8051 MICROCONTROLLER

In this project, we will learn about L293D and L298N Motor Drivers and also about Interfacing DC Motor with 8051 Microcontroller with the help of both L293D and L298N. When we talk about controlling the robot, the first thing comes into the mind is controlling DC motors. Interfacing DC motor to the microcontroller is very important concept in Robotic applications. By interfacing DC motor to the microcontrol ...

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 Array 3711A DC electronic load I recently purchased on eBay. You can find a v ...

3.3V to 30V DC/DC converter using SN6505A

Recently I'v got my samples of SN6505A, it's a really nice IC, so I decided to make a simple DC/DC converter to get familiar with it. What I like in this chip is that it can operate on input voltage as low as 2,5V - that makes it great for battery devices. It's also nice, that it's a very minimalist design - on primary side all what is needed is decoupling capacitor. One disadvantage is that it doesn't have ...

Dual DC Motor Driver For Robot with L298

Dual Motor L298 H-Bridge Control project can control two DC motors connected to it.  The circuit is designed around popular dual H-Bridge L298 from ST. This board can be configured to drive a single motor with high current rating also. This can be achieved with the help of jumpers on the board.  An onboard 5V regulator can take a maximum of 18V of DC input. Should you wish to drive this board with higher vo ...
