Strobit M8 Files

Jans Gentsch has made his compact version of the Strobit Triggr available to the community, his version, the Strobit M08 based on AVR design can be found here.   Please note that there are a couple of things that need doing to the PCB, if you get a chance to implement Jans design, please post back … Continue reading Strobit M8 Files

Tests

Here's are some initial non scientific test results of the prototype. Sidenote: I had some fun testing these outside at night, everytime a car drove past I triggered the strobe, instant brake lights, hehe (The use of speed cameras are notorious here in Western Australia). The Unit, both the master and slave are identical, personality … Continue reading Tests

Protocol

Protocol: Full Detail can be found here on the wiki - http://wiki.everythingrobotics.com/index.php?title=Draft_Proposal The trigger packet transmitted is 7 bytes long.  Preamble(3 bytes), Sync(2 bytes), trigger command (1 byte) and CRC byte. The Preamble is used by the the RF module to tune the Receiver. The Sync word is used by the RF modules receiver circuit to … Continue reading Protocol

Firmware

Firmware Details: At the moment it’s pretty basic, but works!  Source is available via SVN (see download page) The mode is set at powerup by pressing the manual trigger button. If pressed then mode is set to Master, default powerup is in slave mode (i.e.. do nothing). Master mode is identified by a single flash … Continue reading Firmware

Prototype

Prototype Specs: PIC16F88 running on internal 8MHz Clock - low cost and very popular, free development tools available, i.e. C compiler. Works in unlicensed 915MHz ISM Band(Australia/US), can work at 433Mhz by changing RF module(US/EU/Australia). RF uses FSK Modulation - Less prone to interference sources. All aspects of the RF module is configurable via the … Continue reading Prototype

RFM12 FSK Library – Alpha Release

I'm pleased to announce the very ALPHA release of the RFM12 library for the wireless HopeRF RFM12 FSK tranceiver module that I'm using for the strobist open trigger project.  It was developed under BOOSTC for the PIC embedded controller, but should be easily ported to any compiler. Most of it is untested, hence the alpha release, but it's a … Continue reading RFM12 FSK Library – Alpha Release
