CC1110 Instrumentation with Python

by Travis Goodspeed concerning the GirlTech IMME, utilizing the GoodFET's Chipcon Debuggerto instrument Michael Ossmann's $16 Pocket Spectrum Analyzer. Kenwood Spectrum, Overlay Often a neighbor, such as myself, finds himself with a damned useful tool that's missing logging. Further, when this is a black-box application, it is undeniably inconvenient to patch in logging where no commu.......

Designing Notch Filter Circuits

Notch filter circuits are normally used for suppressing, nullifying, or cancelling a particular range of frequencies in order to avoid an annoying or unwanted interference within a circuit configuration. It specifically becomes useful in sensitive audio equipment such as amplifiers, radio receivers where a single or a selected number of unwanted interfering frequencies are required to be eliminated through a simple means. Introduction Active notch filters were actively used during the earlier de.......

Promiscuity is the nRF24L01+\'s Duty

by Travis Goodspeed extending the work of Thorsten Schröder and Max Moserof the KeyKeriki v2. 0 project. NHBadge and a Keyboard Similar to Bluetooth, the protocols of the Nordic VLSI nRF24L01+ chip are designed such that the MAC address of a network participant doubles as a SYNC field, making promiscuous sniffing difficult both by configuration and by hardware. In this short article,.......
