I’ve recently been running the rather excellent PAC-ROM nightlies on my Galaxy Note II, and wrote a simple python script to alert me via Android push notification when a new build is available using the Pushover API.
This gets run as a cron job on one of my servers. It might be a bit niche, but I thought I’d post the code on my GitHub anyway in case anyone else finds it useful:
A python script to check for new Android ROMs and notify your phone.
I’m back! Well, as “back” as I can be seeing as how I never actually went anywhere.
Anyway, I’ve brushed the e-dust off the blog (damn stuff gets everywhere) because I want a place to put a few things:
- Multirotor stuff. I’ve built a tricopter! It’s based on a these RCExplorer designs, but with a few modifications of my own, which I’d like to document in case they’re useful to anyone else. You’ll be able to read about it here, and see it looming ominously in a patch of sky above you soon.
- Software. I’m planning to tidy up a few scripts and programs I’ve written and publish them.
- Squidy! It’s been a while, but the plot thickens.
I’ve also had a bit of a tidy up, fixing broken links and layout issues.
More to come soon!
I was playing about with the Self Level mix mode of the KK2 1.6++ firmware, but due to user error, managed to get it to self-level upside down, 60 metres above the ground, which it then proceeded to slam into. Oops.
The tricopter held up surprisingly well considering the height and speed of impact, and the zip ties did their thing and let the motors break away cleanly, but there is still some damage to see to (cracked body, cracked receiver antenna, broken ESC cable). Time to get the tools out again.
The camera did NOT enjoy the crash – I had to recover, then repair the video file from the SD card, and sadly this is all the footage that there is.
The picture wire seems to have mostly cured the rolling shutter effect, but looking at the raw footage, I’m still getting shake.
Back to the drawing board.
This is one of the first videos I shot using the Mobius ActionCam on my tricopter, using my Super Simple Gimbal. It’s shot at 1080p/30fps, and I’ve not done any post processing on this video – I wanted to get a feel for the amount of vibration/rolling shutter distortion I’d get off the bat, in order to work out what tuning/redesigning I might need to do.
The gimbal is currently attached to a carbon fibre plate suspended from the tricopter using RC fuel tube with very stiff coat hanger wire inside. I’m planning to use larger loops of more flexible wire (picture hanging wire) next, to see if I can get rid of some of the shake. In both cases, the battery is attached to the plate, rather than the tricopter frame. I’ll post a comparison video of a similar flight one I’ve had a chance to test the new damping system.

Testing out my self-built tricopter on the Enfield Playing Fields. I’d never flown *anything* before this, and it kind of shows.
