I booked a place at this event the moment tickets became available on EventBrite. The are now so popular they sell out really fast. Workshops had only 20 places, and booking opened at 7:30pm on the Thursday. Needless to say, I forgot and all workshop tickets got sold out immediately. I was therefore delighted when @recantha (aka Mike Horne, organiser) emailed to say a few tickets had become available. I emailed right back pleading for one on the GPS Tape Measure workshop and got one.
The big day arrived. Arriving not long after 10, I was surprised and delighted to get given a lovely RPI 2 case as I went in. Thanks to @jarjargeek for this tweeted photo. I was too excited to get to the keynote talk and just popped the case in my pocket.
I had to scoot off to get to the GPS workshop in time. It was billed as “An exciting workshop for anyone who has done a little Python programming on their Pi and now wants to take it further.” and it truly was great fun.
After a brief introduction to GPS, we typed in a small program that queried a GPS/GLONASS receiver (a powerful one suitable for cars) that was attached to a Pi to get location information. Having entered and checked the code, we dashed outside to see if it worked. However depite having a ‘fix’ my distance display did not increase as I walked. Back to the workshop to double-check the code.
Such a minor typo! I had used a lowercase letter instead of a capital to refer to a variable with the result that a new variable was created. The increasing distance went into the real variable, while the new variable (still at zero) was displayed on the little LED display. Once sorted, back outside to test it and yippee, it worked.
Just had time to listen to another inspirational talk by David Whale on running STEM clubs, not just high level suggestions but practical tips on making sure you have all your equipment ready and ways to ensure that you don’t spend all your time putting things together and taking them apart.
After this, it was about lunchtime. So after a brief stop at the cafe and its welcome pannini and coffee, it was of to explore the stands and stalls.
So many interesting projects. So much to buy. Needless to say, I had to purchase a RPi II to go in my nifty new case. All the white bits of the case clip on in order to protect the Pi, and off again to allow you to connect things. Really practical
Quite an expensive but really interesting day. Below are a few of the pictures from the day. I loved things like the RPi used to drive a game of space invadors running on a console made out of an old arcade machine. It had been left in the damp so all the insides were rusted to pieces, but the buttons still worked so playing the game had a real feel of the old-style machines, with the little Pi inside controlling it all.
Laura’s wooden artificial intelligence (yes another RPi) was good fun. You put an object on the stand and then spoke to it using the wooden keyboard. She had put all the code she had written in a paper book – a lovely juxtapositioning of old and new, traditional materials and computer technology. Very effective.
And then there was the very loud chair that would read what you had written using sliders that you inserted into lines to make a kind of slate. 3D printers making amazing puzzles, and as I walked around I got the ‘mark of the #PiBirthday’ on my hand and a raffle ticket. I need to check today to see if I won anything 🙂 More RPis perhaps?
So much, the time went all too quickly and we left the venue to those who had bought tickets to the Pi birthday party.
At home, I have dedicated my entire desk to the Raspberry Pi. That way I won’t have to put it away or worry about leaving cables trailing across the living room floor. My infrared camera project beckons. With the RPi II running 6 times faster (and yes, that is obvious from first boot up) the possibilities are increasing.
