I’ve just quit smoking saving myself £300 a month, and I was going to treat myself to a new vacuum cleaner as a reward – I have an older version of the same and it’s fab but this one is even fabber.
But I’ve also started putting together a new python + electronics tutorial for the next Cotswold Jam at the end of April, both setting up my own prototype, and collecting components for 24 kits to be given away to tutorial participants. Sadly, this has taken a significant proportion of my Dyson money, but I think the result of my prototype looks pretty cool, literally:
Big thanks to Pimoroni for the custom Snowflake white version of their limited edition PiBow B+/B2 Coupe Midnight Black, the discount on the 25 mini-PCBs for the kits – you’re stars!
The give away kits will have smaller breadboards instead of the cakeboard shown above, but they’ll all come with the doors with neodymium magnets as the door knobs, reed switch, buzzer, on-off switch and wires.
Zoe’s been invited to the Raspberry Pi Birthday Party in Cambridge on 5th and 6th of March. That means I need to now stop messing with the CF props, and return to using the floppy props that came as part of her kit.
@recantha – here’s a short video taken a few minutes ago to prove she can behave when necessary.
If you are interested in what triggered the transformation, have a look at these comments.
The net results are I’m getting perfect data reads at 1kHz sampling and alpf set to 2. And that’s as good as the sensor can possibly provide.
There’s probably some PID tuning to be done that might stop the low-frequency wobbles due to the gyro PID I gain being a bit too enthusiastic. That would then curtail the drift too.
I’ll post more videos if that turns out to be true.
So the spoiler in yesterday’s photo was another quadcopter flight controller to the left of the keyboards, pending the release of a fantastic new range of quadcopter frames which is being launched next month. More on that once I’ve got my grubby mitts on one.
But that A+ controller has now been flushed down the pan with the launch of the Raspberry Pi Zero, smaller than an A+, double the memory and just as powerful in every other way. I really have know idea how they halved the size of the PCB and yet kept all of the function. And it’s £4 (yes, that’s not a typo, four quid for a computer that runs Linux happily!), and free if you buy this month’s copy of the MagPi magazine.
So I now need to redo the design for the beret board, to shrink it down to the Pi Zero size!
If you’re in the neighbourhood, pop down to the Cotswold Raspberry Jam in Cheltenham on Saturday and see the Pi Zero for yourself!
The next Cotswold Jam is now confirmed – more details here
There are still some tickets left for the yummy event! Drop by and see the fruit and nuts!
I’ve flying Phoebe virtually every day the weather allows in preparation for the indoor demo flight for the CotswoldJam on 26th September 1pm – 4pm at the University of Gloucestershire in Cheltenham. I can confidently say she’s safe.
P.S. Sorry about the video quality, the camera really didn’t the shoot in the shade with sunshine back light.
Phoebe’s “Prior Preparation and Planning Prevents P1$$ Poor Performance” as my german teacher used to say 30 years ago. So I’ve been doing periodic testing in preparation for safety approval on Wednesday to fly at the Cotswold Jam on the 29th.
This morning, I realised there was once further micro tweak I could do which might have a significant effect. What do you think?
This is a 12s flights (3, 6 and 3s at ascent @ 30cm/s, hover and descent @ 30cm/s). To put this in context, previous good flights I videoed have lasted for less than half this. The tweak was simply to change the initialisation code measuring the angle of takeoff. The drift is more than it would be indoors as there was a breeze.
The code ‘s up on GitHub.
Tickets for the next Cotswold Raspberry Jam on Saturday 26th September from 1pm to 4pm are now available via the Cotswold Jam website.
