CNC Machine built using floppy drives
Richard Harris has produced a series of video tutorials on how to build a low cost micro CNC machine that uses old floppy drives for the movement. The video above is 10 in the series, if you would like to build you own you will need to start from video 1 which is here. It won’t do […]
Arduino and SIM900 GSM Modules tutorial
John Boxall over at Tronixstuff has a series of Arduino tutorials. This chapter fifty-five of a series will show you how to use the SIM900 GSM modules with Arduino: The goal of this tutorial is to illustrate various methods of interaction between an Arduino Uno (or compatible) and the GSM cellular network using a SIM900 GSM […]
A method of applying a precision reference voltage to an Arduino AREF pin, without accidentally blowing up the processor
Telford Dorr shared a tutorial on how to apply a precision voltage to the AtMega Aref pin without accidentally blowing up the processor. There’s a better way: feed the Aref pin resistor with an op-amp, and connect the op-amp negative feedback input directly to Aref. The op-amp will generate whatever output voltage is needed (within its […]

TI Ez430 Chronos watch – Getting started on custom firmwares: Elpaso, from the 43oh Forums has written a nice tutorial on how to get started on the Ez430 Chronos watch with what is out there currently. He covers the watch, the control center, wireless updates and custom firmwares. Via 43oh.
Super light weight RC FPV quadcopter DIY solution
Oscar writes: The compact FPV system I have built is only about 20g, now even my mini quadcopter and micro hexacopter can carry this FPV camera and video transmitter. In this post I will share with you what are the parts you will need and how I made it.
Proverbial LED blink program for chipKit DP32
Ras B blogged about his chipKIT DP 32 he won in our last week chipKIt giveaway: Ok I just could not resist, and had to post the Proverbial Led blink Program adapted for the DP32, that has 4 LED’s on the board ( Digital Pins 11 to 14). Will scroll them from right to left, speed varying on the […]
Ultra Librarian and Eagle tutorial
Luca Dentella writes: Ultra Librarian is a tool by Accelerated Designs to manage libraries of eletronic components (CAD design, simulation, 3d-modelling…). Many IC manufacturers provide Ultra Librarian files (.bxl) for their products: this tutorial will show how to use those files in Eagle… Via the contact form.
Downloadable ShenZhen map for makers
We are a great fan of Shenzhen and love the wandering round the vast partmarkets of Huaqiangbei, Shenzhen. Ian even decided to leave the cold and windy Netherlands and settle in the Shenzhen area. Two years ago we start our first steps in Huaqiangbei during our first geek tour of Shenzhen, but now we are veterans and know […]
Arduino and PCF8563 real time clock IC
John Boxall over at Tronixstuff has a series of Arduino tutorials. This chapter fifty-four of a series will show you how to use the NXP PCF8563 real-time clock IC with Arduino: Recently a few people have been asking about the PCF8563 real-time clock IC from NXP – so this is a tutorial on how to use […]
Bringing OpenWRT to TL-WA801ND v2 (Part 2, building OpenWRT)
TasksOfOhm has posted a detailed tutorial on building OpenWRT on TL-WA801ND v2 : After getting some details about the board it was time to create a build environment. In my case this was just about copying one of the VMs I have prepared just for this purpose. The build environment requires a Linux machine whereas it doesn’t […]
HackRF and POCSAG decoding
BinaryRF has posted a detailed tutorial on using the HackRF SDR to decode POCSAG pager traffic. He starts with the HackRF hardware connected to his Ubuntu Linux box. The basic procedure involves using gqrx, then pipingthe audio output to multimon decoding software using the pavucontrol program.
74HC4067 16-Channel analog multiplexer demultiplexer
Here’s another tutorial by John Boxall of Tronixstuff: 74HC4067 16-channel analog multiplexer demultiplexer Now and again there’s a need to expand the I/O capabilities of your chosen micorocontroller, and instead of upgrading you can often use external parts to help solve the problem. One example of this is the 74HC4067 16-channel analog multiplexer demultiplexer. That’s a […]
