Twycross Zoo


Elephants at Twycross
Visited Twycross Zoo with Ashley Bryant, to meet elephant keepers and discuss the best location for an acoustic enrichment device.  Ashley's research involves testing a new behavioural analysis tool developed by the Elephant Welfare Group (EWG) and we're planning to work together at Twycross, using one of my elephant audio systems.

Valli and vibrotactile buttons

Valli explores vibrotactile button
Finished knitting another elephant button in Carmarthen last night.

Foot pedal button

We visited Skanda Vale again on Saturday to catch up with Valli.  Brother Stefan has been making her a hosepipe football - she's been having some fun with it, but only plays when there is someone else joining in.  She looks like a gigantic puppy.  http://www.skandavale.org/elephant-plays-football/

Foot pedal button
This time, we were testing a giant button made from an old sewing machine foot pedal. 

This would normally provide a variable output, but I simplified it to ON/OFF and we created a wooden housing that surrounded the case so that Valli wouldn't be able to grasp the button with her trunk, only push it.

The button was bolted to the fence across the balcony. 

Valli explores the button casing
Wire out the back (on the non-elephant side) connected Arduino to my laptop and activated  a Processing sketch that played a 1 second audio sample.

We tested a low rumble, didgeridoo, tuba, double-bass and contra-bassoon.

Valli seemed interested in exploring the shape and contours of the new button, but was reluctant to push it.  Brother Stefan thinks that an alternative embedded sensor that just requires touch will be more successful with acoustic stimulation.

Skanda Vale

Skanda Vale is a multi-faith ashram in the Welsh countryside, who keep a temple elephant, Valli.   I went to visit Valli and her keepers at the Ashram on 21st Oct 2015, invited by Brother Stefan, who is interested in developing some novel enrichment for her.
 
Valli says "Good morning"
Valli came to Skanda Vale as an orphan when she was 2 months old and slept initially on Brother Peter’s chest, so he is her natural leader (mother figure). Valli is Full Contact with her keepers, and indeed, everyone she meets at Skanda Vale.





Elephant shed outside
Valli has a new elephant shed, which featured recently in Green Building magazine (Vol 24.  No. 2) because of its clever environmentally (and elephant) friendly design, conceived and project-managed by Brother Stefan.  The shed has sandy substrate and also a padded flat floor, for washing. There are 2 doors, one of which can be opened form inside, leading to paddock with electric fence. The other can only be opened by keeper, and leads to exit when Valli goes for walks.

Elephant shed inside
There is a small pool with waterfall and a fenced area which has access to the corridor outside, with bars wide enough for people to easily access. There are 2 heated walls, pipes set in concrete, with a wood-fired boiler and large insulated tank. A balcony overlooks the shed and there is also living accommodation – Brother Peter stays here.

The balcony area would be ideal for mounting a system of inverted bucket-buttons that Valli could reach. She could break the beams and a sound would be activated. She would have to keep her trunk inside the bucket to continue playing the sound. The speakers can be placed on the balcony, where there is an electricity supply, so the button would control an aspect of the environment next to it. Similarly, buttons to control wall temperature, for example, could be situated beside the wall.

Valli currently shares the space with Raf, an old male macaw which has been ill and is taking medication from Bro. Peter.  We take her for her second long walk of the day - up into the woodland.

Woodland walk with Valli
During the walk, Valli repeatedly attempts to stop and eat grass and leaves. B. Stefan says that at this time of year, the nourishment in grass is limited, compared with spring grass, which is full of nutrients. He regularly stops her from eating, because the idea of the walk is to give Valli exercise,  so she works to get to a meadow where she can stop and forage. She likes willow and broom, sometimes brambles.

Raf
When we return, it is time to play Valli some audio, to check that the different sounds do not make her scared. B. Peter says that a wildlife program terrified her when she was younger; B. Stefan says that she does not enjoy drums. It is likely that she can hear the drums being played at the temples at the bottom of the hill. There are 6 sets of prayers every day. B. Danny says he often plays her Grateful Dead, while B. Peter plays Bluegrass.

I have a selection of didgeridoo tracks by Ancien, Outback, Reiki Music Academy and some Bass Mekanik tracks from their album “Sonic Overload”, which includes very low frequency tracks, designed to test people’s speakers. There are samples ranging from 100Hz down to 10Hz. We connect my laptop (which can’t produce any sound lower than about 80Hz, but which can nevertheless play the MP3s) to Skanda Vale speakers and play Valli some didgi music and some low freq samples. I video her reactions. She appears to be listening.

Valli is not scared by the sound production and her keepers are enthusiastic about giving her an opportunity to control the production of audio. When she understands that she can control an aspect of her environment, and is confident doing this, the plan will be to use similar buttons/controls to allow her to control other things, such as the temperature of the wall, the lighting, showers or dust baths etc.

EMF Camp 2014

ElectroMagnetic Field 2014
Near Milton Keynes, last weekend of the school holidays.

The light saber workshop kick-started the weekend and broke the ice with all the kids - swimming pool noodles + tape.

Kite-mapping was fun - we attached a camera to a picovet hanging from string of kite and launched it from the field.  The resulting photos showed the landscape emerging every 3 seconds as the camera rose.





There was a very popular retro gaming tent where kids tried Pacman ("it's great!") and Indiana Jones pinball (I had the top score) for the first time.

A gigantic LAN tent with Free Quake for Linux; a badge made from a micro-controller with LCD screen -  TiLDA MKe -

We hammered silver rings, played with makeymakey, learned how to pick locks and tasted freshly made Dutch waffles.

Laser-cutting was cool - perspex dragons sketched on paper, drawn in Flash, exported to Inkscape and tidied up for the hardware.  These were inspired by hanging birds and mobiles.

Technology Will Save Us DIY Synth


My sons are way better at soldering than me after about 5 minutes...

We went to Technology Will Save Us and Little Bits Global Make-athon at Limewharf, Vyner Street.  DIY little synths were very successful, and we also constructed Snowkilla the Iceman with revolving chainsaw...

Rude Cats

Clips from toy theatre project, using TAGS hidden in the puppets and an RFID reader in the cottage.  The cats make different comments depending on who approaches.  Lots of fun making puppets and voicing cats.

 
Using Processing to play audio files, triggered via Arduino (with RFID reader) connected through serial port.  The cats have a range of responses for each tag, so the output is randomised.  You can hear the same audio clip being invoked more than once so the sounds overlap.

Digital Toy Design

This was the first year we taught Toy Design as part of the BSc Computer Games degree. Second year students were asked to undertake a small piece of research into toys, then produce their own concepts and working prototypes, using Arduino as base hardware development environment.  The module focused on technical aspects rather than aesthetics.

After a basic introduction to electronics - a reminder to those who had done physics at school - we launched into some toy-hacking. 

The local car boot sale provided plenty of material, including a talking Elmo, a motorised train, a dancemat game and electronic language lotto.  Our electronic labs also had a few old keyboards to deconstruct.  These all proved useful for demonstrating the simplicity of the technology underpinning seemingly complex electronic devices.

Students began to play with the kits, experimenting with sketches and different sensors. We showed them how to construct their own large pressure pad sensors (buttons), how to link Flash with Arduino, how to create simple applications using Processing, how to solder components.

Working in small teams, they came up with the following concepts: laser-activated hit-blob game; pressure-pad alarm system for a house (not really a toy); "simon says" game (match the light sequence); musical soctopus. 

For non-programmers, "simon says" game was trickier than they expected.  The alarm system cautiously worked by showing which doors had been breached on a processing application.  Jamie and Kyle's laser-target game was successful and fun to play.  Soctopus got the award for best sewing technique...

PaintJam

It started with a fishing game.  Transformed into an observation of magnets.  Became a snake chasing marbles.  Metamorphosed into an automated drawing tool... using metal balls.  Jumped out into ovenware and lost the motor.  Evolved until finally even the marbles disappeared and total human control took over.  Check the video.
