I’ve already posted about a 3d printer funded by Kickstarter. Today I found, on Kickstarter again, an interesting project by ThingM, named blink(1). The idea behind it is very simple: an RGB led powered and controlled via USB. blink(1) is detected as an HID device by computers, so it doesn’t need any drivers being compatible with every O.S.; ThingM promised the controlling…
Emanuele wrote a post about an interesting project, based on a PIC microcontroller, to send collected data to Google Spreadsheets. Using this Google app, you can also create graphs, so you can keep your data in the cloud and follow their fluctuations:
MagPi is a new magazine, online and free, about the new RaspberryPi hardware platform. You can read it online or download in PDF format, enjoy your reading!
The Massachusetts Institute of Technology (MIT) and Harvard University announced today a joint partnership to offer a new e-learning platform, called edX. Goal of the project is to offer online courses on different subjects (mainly related to information technology) for free. The project will develop a new e-learning platform that will be released with an opensource license. It will be certainly a…
Tom, from Milwaukee Hacker Space, tested a very fast way to etch your circuit boards: he uses a mix of muriatic acid and high-concentrated (30%) hydrogen peroxide and wipes the copper away with a sponge. Here’s a video showing the board completely cleaned in few seconds: Please be careful with the acid and work in a…
Dave devloped a very interesting tool for Arduino IDE, called Upload-And-Retrieve-Source. With that tool, you can use Github as a repository for your sketches: you can upload and retrieve them using friendly menu items: Github also features version tracking: Via: Hack a Day
Some weeks ago I ordered some items from Sure Electronics. Yesterday I received the parcel and I was very surprised about the care they put in packaging: they used a bubble cushioned envelope; every item was in a plastic bag labeled with item code and description; inside the bag, the items were placed in plastic boxes…
Recently, a security vulnerability has been found on Github website; the vulnerability made it possible for an attacker to add new SSH keys and to use them to pull/push code on other users’ repositories. The vulnerability has been solved on 4th March; every user is required to approve his SSH keys connecting to the following address: https://github.com/settings/ssh/audit: Approval…
DangerousPrototypes posted today a great tutorial about how to make new parts in Eagle… a must reading for all the users of this software! Eagle’s popularity is partly due to the sheer number of parts and footprint libraries available for it. Sometimes you can’t find the part you need in an existing library though, and it’s…
Take a look to the Kidogo project, by Dilshan R Jayakody, an engineer from Sri Lanka; it is a very useful digital signal injector with 8 channels: The project is composed by two elements: a board, with Microchip’s PIC18F2550 and USB interface; a software (Kidogo Player) running on a PC that allows to “draw” digital signals. Kidogo…
