DIY Dual Stepper Motor Driver Shield for Arduino

Stepper motors are brushless DC motors which can move in discrete steps thanks to the special coil arrangement inside. They are very popular in DIY and industry projects which require accurate mechanical movement control.  In this SoloPCB Designer project, we are building a dual stepper motor driver shield based on two Allegro A4988 ICs which can supply up to 35V and 2A and provide overcurrent and thermal p ...

6 Digit LED Clock

I recently found six 2.3″ red 7 segment displays in my collection which I purchased from Rapid Electronics when they were clearing out non-RoHS stock. Since I have no clock at my work bench I decided to construct one from some prototyping pad board, a Microchip PIC18F26K20 microcontroller and a Dallas DS32KHZ temperature compensated 32.768kHz crystal. The displays I used are SA23-12SRWA, which don’t appear ...

An adapter with standby power consumption below 0.1W already on stock

DoE 2016 is a known term naming stringent regulations established by DoE (department of energy USA) valid from year 2016. Among other things it brings a requirement for a standby power consumption of small adapters to be below 0.1W. In Europe we have here a limit of 0.5W for majority of small adapters, but even here can be expected toughening in the nearest years. That´s why German company Friwo as a long-t ...

Short circuit protection for (almost) any power supply

Hello, everyone! This instructable is about a universal short circuit protection that I've designed to use in bench power supplies. I've designed it to fit in most power supplies circuits. In order to this circuit fit in your bench power supply, you will need to do some calculations, but don't worry, I'll explain everything on the next steps. The circuit is really easy to understand. A resistor of low value ...

The CANable: a small USB to CAN adapter

The CANable is a hardware clone of Eric Evenchick’s CANtact project, an open-hardware USB to CAN adapter compatible with socketcan. I took his design and reworked the hardware to be a bit more suitable for my personal needs, with a screw terminal instead of a DB9 connector and a much smaller PCB. The design is open-source hardware and the schematic is nearly identical to CANtact except CANable uses the STM3 ...

PID Theory Explained

Overview Proportional-Integral-Derivative (PID) control is the most common control algorithm used in industry and has been universally accepted in industrial control. The popularity of PID controllers can be attributed partly to their robust performance in a wide range of operating conditions and partly to their functional simplicity, which allows engineers to operate them in a simple, straightforward manne ...
