Read serial data without PC on GLCD
Hemal Chevli wrote an article detailing his new tool the GLCDTerm that reads serial data without PC on GLCD: I’m calling it GLCDTerm(spin-off from GTKTerm), this handy tool reads TTL serial data and displays it on GLCD. This is the first time I’ve used a GLCD in any of my projects. It runs on m328 using arduino bootloaer and the […]
SMD soldering station for Weller soldering tips
Martin Kumm writes: This page provides documents about a cheap SMD solder station built as an Arduino shield (Arduino UNO). It supports active soldering tips from Weller (RT series) which contain the heating element as well as a sensor and provides a standard 3.5 mm jack. Together with the corresponding female connector you will get […]
Simple soldering iron driver (SSID) with Arduino PID control
Carlazar posted pictures of his simple soldering iron driver (SSID) with Arduino PID control in the project log forum: Main features are: – Any thermocouple type irons. – Additional control mode: On-Off controller (besides PID PWM). – External power supply: Some standard Notebook power supply DC 19V, 4.74A. – Small dimensions: It fits into 90mm […]
The Final key – Hacking challenge
A followup to the final key – Hardware password manager post, DusteD wants to giveaway a Final key to the first person who can document a method to extract passwords from the key: I would like to point to the Final key main page describing the usage and some of the security aspects of the device, and also […]
Digispark Pro – tiny, Arduino ready, USB and mobile dev board
Ihsan informs us of Digitstump’s inexpensive, tiny Arduino IDE ready, USB and mobile dev board, the Digispark Pro: Serial over USB debugging, USB programmable, 14 i/o, SPI, I2C, UART, USB Device Emulation, Mobile Development Ready, Optional BT, BLE, Mesh, and Wi-Fi. The super small, dirt cheap, always open source, Arduino compatible, USB (and Mobile and Wireless!) development […]
Proto I/Os Arduino
Ricardo of Electropepper writes about their latest project: Now i want to show you my most recent project, an arduino shield aimed for prototyping, it has 8 LEDs, four buttons a buzzer and a temperature sensor, like everything else in my website its all open source, you can check the project here Via the contact form.

The final key – Hardware password manager
The final key – Hardware password manager by cyberstalker.dk The Final Key is a piece technology that solves a problem. The Final Key is a hardware password manager with encryption and focus on combining portability, compatibility security and easy of use. It is a hobbyproject of mine and not under any commercial distribution, you are also free […]
Optical mouse video output hack
The $5 mouse that you just tossed in the garbage might have had some hackable life still in it. As Conor Peterson shows us most optical mice are actually quite simply in operation with most of the hard work being done by the low resolution camera sensor. With a bit of Arduino code he was able to […]
DIY Arduino bluetooth programming shield
Here’s a how-to on making a DIY Arduino Bluetooth programming shield by Joshua Newell: If you’ve ever wished you could program your Arduino without lugging a USB cable around, wanted to put an Arduino project somewhere out-of-reach but still be able to easily upload changes to it, thought about building a project that interfaces with an […]
SMD March – Tweaks to Ishan Kehribar’s ethernet gateway
TomKeddie writes: For our SMD March workshops I chose Ishan Keribar’s Embedded Ethernet Gateway. I added an FT230X and usb port with a Arduino uno style reset on CTS (230X has no DTR but avrdude toggles both). I also used a SOB 5050 template to make cases easy to design. By adding an 8MHz variant […]
RGB lamp made from an old scanner
Here’s an RGB LED Lamp made from old scanner parts and controlled via a web panel with a colour picker by Hack Shed: We have come up with LANp – This is an Arduino and Ethernet Shield that controls an RGB LED colour real-time with a Javascript colour picker. What’s in it? 1x Arduino 1x Arduino […]

Colour sensor project
Iamzxlee has written an article detailing his colour sensor project: Basically, the sensor consists of three LEDs and Light Dependent Resistor (LDR). The LDR will detect the colour and display it to another RGB LED. Besides display it on the RGB LED, the colour will also display on PC. RGB LED is commonly used in display colours […]
antiAFK project
scasagrande shared his project antiAFK in the project log forum: The antiAFK is essentially a stripped down Arduino Leonardo with the intention of sending occasional keyboard commands to the attached PC with the intention of preventing the user from being logged out of online games due to inactivity. This can help on high population servers […]
Autonomous iPad playing robot
Tom Randle made this robot that automatically plays Leap Sheep on the iPad: On a complete whim about 2 years ago, I decided to make a robot to autonomously play one of my favourite iPhone games: Leap Sheep. The game’s nice and simple so lends itself really well to automation. Sheep run from left to right, […]
Arduino plant mister
In this video Johnny Klaus demonstrates using a car door lock motor and an Arduino to mist his plants: A little project I’m working on. Using a car door lock motor and arduino with relay because it will be misting the plant every hour or so, and the 12v transformer doesn’t have to be constantly on. Via […]
Arduino libraries uploaded to GitHub
Kerry Wong writes: Over the years I have created quite a few libraries for Arduino. I finally uploaded them to GitHub a couple of days ago so that they are now all at one place and are easier to find. Here’s a list of the corresponding posts: MCP2210 Library — Reference Interfacing DS7505 AD7705/AD7706 Library […]
Temperature Shield for BBA3, part II
Kevin Rye posted an update on his Temperature Shield project we covered previously: It’s amazing how close I came to matching my 3D model! It’s just like I imagined it. I had already loaded my sketch before assembling it, so it was just a matter of crossing my fingers and plugging it in. Boom! It works like a […]
