enc28J60 and Arduino (7)
When I published my first example about using Arduino as a webserver, many of you wrote me asking how to control Arduino using a web browser: in this blog post I’m going to show you how to control a LED from a web page.
Are you sick of beige?
If you are sick of ugly beige cases that hide your beautiful projects, Ian from Dangerous Prototypes may have the right solution! 😉 With Sick_of_Beige project, DP with the help of David Moberly reached two goals: [checklist] define standard sizes for its PCBs; design PCB cases that are compatible with those sizes. [/checklist] PCB PCB sizes are defined…
OLinuXino and Android
OLinuXino is a family of development boards designed by Olimex. The A13-OLinuXino board is based on AllWinner A13 processor with CortexA8 core; you can follow its design on the project’s official blogsite. Some days ago, Olimex developers were able to boot Android operating system:
blink(1)
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…
BTSwitch
The BTSwitch project was developed to switch electric devices (lamps…) using an Android smartphone. In the following video, you can watch the device working, while in the next pages you can find some technical details… enjoy your reading!
Eagle – Pins with the same name
When you create a new device, sometimes you need to give the same name to two or more pins (in the following example, an Arduino Pro Mini has two reset pins, RST). If you try to rename the second pin, you get an error: The solution is very simple: name the pin: name@number, for example RST@2: When…
mbed NXP LPC11U24, review
Farnell kindly offered me to test and review the new microcontroller in mbed family, the NXP LPC11U24. mbed microcontrollers are designed for rapid prototyping: [checklist] run a microprocessor (ARM Cortex) with all the required components; connect to PC via USB for firmware uploading; have a breadboard friendly shape (DIP win 40 pins). [/checklist] Since a few weeks, the new…
Send data to Google Spreadsheets
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:
Eagle – How to copy items between libraries
When you create a new device in Eagle, you may need to use an item (symbol or package) already available in a different library. First, open your library: Then right click on the item you need to import and choose Copy to Library: The item will be added to your library and you’ll be able…
MIT + Harvard = edX
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…
