Cheap wireless solution for AVR/MCU projects.



The nRF24L01+ is a 2.4GHZ RF Transceiver produced by NORDIC semiconductor, it is a very small , powerful and low-power solution for your home project. I am studying how to interface with my AVR MCUs. Luckily, I found out someone has a driver written for AVR, it is well-documented and easy to follow. Check out the link here: http://www.tinkerer.eu/AVRLib/nRF24L01. Basically, you need to have a SPI interface, so most of the AVR MCUs have! so How far can it goes? Sparkfun did a test, around 360feet LOS.

Robo One humanoid robots get demostrated in Hong Kong.

Just get back from an event showing the robo-one humanoid robots in Hong Kong. For the readers who don't know what is Robo-one, Robo-one is a humanoid robot wrestling game in Japan, which is a one-on-one match. Each side controls a humanoid robot and tries to make another side fall on the ground. Many Japanese players create their own humanoid robot for the competition. The KYOSHO, a famous RF toys maker, produced 2 humanoid robots (MANOI PF01 & AT01) which can be played in robo-one. So now you can purchase one from kyosho and modify your own without building from scratch!

Some photos from the event:

Blimpbot controlled by Android G1 wirelessly.



It is controlled by moving the android G1, the directions are calculated from the accelerometer inside the android G1. So you G1 is just like your Wiimote now. Moreover, there is a camera on the blimp, so you can see the video streaming from the blimp in real time also. It is a really cool project. I hope I can play with blimp too! May be later, you all may see my blimp project:) Cheers.
