1.8V or 3.3V ?

Is it better to run CC2650, CC2640, CC1350 or CC1310 SoCs from Texas Instruments keeping in mind ultra low power and utilizing energy harvesting at 1.8V (but consume larger current) or at higher voltages (like 3.3V ) but consume lesser current? Well, it depends. The performance will be similar because the core runs at 1.6V … Continue reading 1.8V or 3.3V ?

Hacking a Rock Crawler to run on 27MHz and 2.4GHz using nRF24L01+ transceivers – Part 1

I had this Rock Crawler (from now on rock crawler would be abbreviated as RC) that originally ran on 27MHz. This is NOT a differential drive vehicle, it uses a steering mechanism to turn. In the booklet that i received with this RC it was mentioned that the maximum range is 10 mts and it … Continue reading Hacking a Rock Crawler to run on 27MHz and 2.4GHz using nRF24L01+ transceivers – Part 1

Time comparison between normal TX-RX mode and Auto Ack payloads

http://youtu.be/MOMZrCw6ql8 If you have read the library properly then you know how the transceivers and the functions that have been developed work i.e what happens in a normal mode where we switch between Rx and Tx mode and how the Auto ack mode works. Anyways let me tell you once again in brief - In … Continue reading Time comparison between normal TX-RX mode and Auto Ack payloads

Taking input from Processing and transmitting it wirelessly to control a remote set of leds

The nrf library allows us to send only integers , characters , bytes but not Strings objects (you can definitely send character arrays i.e strings). But it is really easy to communicate from Processing to Arduino using String objects because of the ease and the many ways in which we can manipulate Strings in complex … Continue reading Taking input from Processing and transmitting it wirelessly to control a remote set of leds
