Converting an Inkjet Printer to Print PCBs: SEE STEP 12 FOR NEW RESULTS AND AN ETCHING/PROJECT UPDATE! Recently one of my focuses has been to find a way to make the PCB (Printed Circuit Board) creation process easier. I like being able to design something based on what I want in a circuit an…
A great solid-state project where National Semiconductor’s (since 2011, a part of Texas Instruments) LM4702 meets up with Renesas lateral MOSFETs, this article by Jack Walton was originally published in audioXpress July 2007 and it is still cited as a reference today. An ideal project for the DIY enthusiasts.
This is Lesson 4 in the Learn Arduino Adafruit series. In this lesson, you will learn how to use eight LEDs using the 74HC595 shift register chip.

In my previous blogs I started a new project Raspberry Pi® – Powerunit® with a follow up about the software here. Hereafter I designed the PCB in KICAD here.
ATtiny85/45/25 LED Dice (Super Simple and CHEAP!): If you have looked at my 5 LED ATtiny85 POV display, we programmed the ATtiny with the Arduino. (If you haven't seen it, click here) We will be doing the same thing for this LED Dice project. The total parts cost for this project is about $5-$10.…
DIY PCB Milling Machine - Part 1 - Building Frame: Hi Everyone. Welcome to Media Milan with me JCRP. A maker space is never complete without any fast method to prototype a Electronics project. And the longest process in it is to make the PCBs. Till now I have been using the Toner transfer method a…

The changeable duty cycle is ranging from 50% to 100%. Note: There are four different frequency ranges to be selected by moving the jumper. ▼ Features: 1. As a square wave signal generator for experimental development 2. Used to drive a stepper motor for generating a square wave drive signal 3. Generate adjustable pulse for MCU 4. Generate adjustable pulse, to control circuitry associated ▼ Specifications Chipset: NE555 Operating voltage: 5 ~ 15 VDC 5V output current 15mA± 12V output current 35mA± (V-PP greater than 50%) Input current: >
Been having a play with this little circuit. It produces a square wave and a triangle. It's based around a 553 op amp, the caps and resistors are currently being swapped out to test for best results. (excuse the chain of capacitors at the bottom of the board, I didn't have the right capacitor value…

Arduino - Radar/Ultrasonic Detector: One of projects was Arduino radar on my faculty. Easy and simple build. I will put pictures and code for Arduino! In few sentences i will introduce you to project... The detector is a device measuring device that reveals the existence of a phenome…
As a company we needed a PnP machine to make our products faster. Most of the PnP machines we found online were expensive, inaccurate, loud, and incomplete. It didn't take us long to decide this was going to be our next project. The goal is to make a fully automated machine with fully automated feeders that are easily replaced anywhere in the stack. Also, the Pick and Place will use CV for accurate placement.
Audio Junkbot: I'm one of those people who keeps broken electronics because "I might use that for something one day". Well, I had a broken cd/cassette/radio that someone gave to me because it kept turning off randomly. It turns out that the problem was just a bad…
