Trying to fit the functionality into the existing ebay trigger receiver housing seems to be a royal pain in the butt, especially trying to work in with the batteries, so after a few days of PCB redesigns and juggling compments around I have put that particular design on hold and moved forward with my original PIC16F873A design, also I did not like the fact that there was 2 circuits to maintain, a transmitter and receiver, this then leads me to the next problem. I want something easy for the end user, something similar to the Pocket Wizard Plus that is really a no brainer for the user to drive, i.e. a switch to select operation mode and channels, a 3 and 4 way slide switch respectivly, well do you think I can source any 4 way slide switches easily? Seems I can get some 3 way easily enough, and I guess I could use a rotary switch but these are too clunky for my liking, but still an option.
A couple of design changes, main one being I could not physically fit a single design into the existing housings that would encompass the Tx and RX, the RX housing is the problem as it’s a fairly small board so that means I’ve had to change the processor so that I can physically fit everything as well as the RF onto the board, so now a single design using the PIC 16F873A now becomes 2 circuits, Tx and Rx using a PIC16F88 as the MPU.
I’ve put an initial design (both eagle source files and PDF) into SVN that is aimed as a board replacement to the ebay triggers.
Things seem to have slowed down on the forums qute a bit, I’ve also put a poll up for the project name, based on a few from the marketing topic where a number of people have put forward their suggestions, well, while the poll has been viewed a large number, only 12 people have voted so far, a bit dissapointing, obviously they didn’t like the names I’ve pulled from the forums, Oh well I know you can’t please everyone.
Anyway moving forward….I’ve been busy researching RF modules and coming up with a prototype design. Currently I have 2 prototypes designs on the go. One as a drop in board replacement for the Ebay Triggers based on the RFPIC, the other as a Pocket Wizard type trigger, but hackable, based on the Phillips LPC2148 ARM7 Chip. The designs are not complete by any means. I’m still in 2 minds about the RFPIC Design I may for go it in favour of a standard pic with an external RF module, that way I could use the same RF module in both designs.
