Fresh hacks every day
We asked for responses to our last Development Board post, and you all followed through. We got comments, forum posts, and emails filled with your opinions. Like last time, there is no way we could cover every board, so here are a few more that seemed to be popular crowd choices. Feel free to keep sending us your favorite boards, we may end up featuring them at a later date! … [Read more...]
There are a ton of rapid prototyping available on the market these days which all cater to different niches. Todays project, a robotic rover on a 4 wheel chassis, is based on the NXP mbed. The mbed is a popular board for higher need applications, and is centered around an ARM Cortex core. This multi-part writeup is a great place to start for people who are looking into making a robot of any … [Read more...]
This tweeting RFID reader is a great working example for the mbed. When an RFID tag is read it is matched with the name of the owner and a Twitter message is sent out. This is very similar to the RFID cat tracker that used an Arduino. The code is short and simple due to the use of available mbed libraries. The hardware needs just two extra modules, an RFID reader and an Ethernet socket. If … [Read more...]
Ah, the heady aroma of damp engineers! It’s raining in Silicon Valley, where the 2010 Embedded Systems Conference is getting off the ground at San Jose’s McEnery Convention Center. ESC is primarily an industry event. In the past there’s been some lighter fare such as Parallax, Inc. representing the hobbyist market and giant robot giraffes walking the expo. With the economy now turned … [Read more...]
[Vsergeev] built an echo pedal for a guitar or with other audio manipulation applications. He used an mbed microcontroller for the project. You may remember Hackaday writer [Phil] labeling the mbed an 'Arduino on steroids', and it certainly handles this audio processing quite well. We've included a clip of the echo effect after the break. During the design process, [Vsergeev] used LTspice to … [Read more...]
How's this for a first microcontroller project: a ticker that pulls messages from the Internet and scrolls them on a set of numitrons. [David Barton] built this using an mbed microcontroller. Tapping an ethernet library he got this to pull data from his server by connecting directly to the cat5 cables. The display consists of three numitrons which are incandescent 7-segment displays. In the video … [Read more...]
We were going to take a break from posting clocks. Really we were. This one came in the tip line today though, and we just couldn't pass it up. [Alex] has built, what might be the most complicated clock we've seen. At least, it would appear that way initially. This Binary clock shows Hours, Minutes, Seconds, Days, and Months. He started with a picaxe, but eventually settled on an Mbed. Yes, he … [Read more...]
