The Eagle PCB design files are now available for download from the Strobit Project Page. Constructive feedback is appreciated. Please treat these as an early alpha release, the PCB has not yet been verified. I have also released the design files for a blank personality board, this can be used as a starting point for … Continue reading Strobit early public release
As mentioned in a previous post, Bill Grundmann has been documenting his investigation into Canons E-TTL protocol. Bill has just released a PDF summarising what he has found so far. I’ve yet to go over it in detail, but for those looking at doing some E-TTL investigation of their own this document is a must. … Continue reading More E-TTL info from Bill
The Strobit Project now has some Google groups enabled. Feel free to join these and take part in the discussion. I will leave the old forums up for archival/historical purposes, but will become read only eventually. See Strobit Project Page for the groups.
As one does while in bed at 3am and unable to sleep, I was thinking of the Strobit Triggr (which is probably why I couldn’t get to sleep in the first place) an idea presented itself for Arduino type shields (in particular Strobit Triggr personality boards) where they could be given some real personality. Currently … Continue reading Arduino Shields with Real Personality
As “Everything Robotics” just doesn’t seem to cut it anymore (I can just here the comments as people stumble across the site “hmm not much robotics happening here”). The blog now has a new name “Strobotics” (Stro-botics) which seems to reflect the content a little better don’t you think? A new domain strobotics.com.au is now … Continue reading Blog new name
The Strobit Triggr project now has a proper open source home, a Google Code project page - http://code.google.com/p/strobit/ If you think you can contribute please join the project. Over the next few days as time permits, I’ll be adding everything I have so far to source control for the current design. All hardware will fall … Continue reading Strobit now has a Google Code Project home
More success from Bill Grundmann in his attempt to decrypt Canons E-TTL protocol ! It appears that there is a consistent 4msec delay between when the CLK signal from the camera body drops to GND and when the actual flash is triggered. This would give us plenty of “leeway” in our timing to sync with … Continue reading Canon E-TTL Timings
Seeing as I’m a canon person as far as bodies and lens goes I thought I’d look into the E-TTL protocol and how the camera body and the flash can talk to each other. I’m not looking to completely implement the E-TTL protocol in the Strobit Triggr, (well not yet anyway), but more along the … Continue reading Strobit Triggr and Canons E-TTL
I’ve put all the newer components online, sketchup models are now in googles 3d warehouse and Eagle3D added to the existing library. Sketchup Models: Eagle3D library: Located here
Here are the final renderings from POV with the basic personality board installed, along with a 900MHZ antenna. I’m pretty happy now, looks OK and now will see how accurate this exercise really is when I get prototype boards back.
Some more components added to the Strobit Eagle3d Library. Can be found here. Sparkfun SMA PCB Edge 3.5mm Phone Jack SMD
Ok not quite finished, but almost there! I’ve had to make a few minor changes. I’m glad I’ve taken the time to learn and play around with Eagle 3D, it had highlighted some potential clearance problems. Rather than rush things I’ve decided to take a bit of time modelling than fork out my $$$ and … Continue reading Strobit Board – some minor tweaks
Strobit Eagle3D Library now available for download….see Eagle3D Page
HopeRF 433Mhz / 915Mhz Experimental 2.4GHZ
I’ve been playing around with Googles sketchup over the weekend and have created some components, one the RFM12B module and a basic camera hotshoe to scale. It’s been a great little exercise in learning both Alibre and Sketchup as I’ve been wanting to get some 3D modelling practice, I’m finding that it’s easier to create … Continue reading Strobit Google Sketchup Models
