New can hardware now available
We now sell infra-red emitting cans for use with your own virtual graffiti setup. 100% designed and made in our UK workshop – regular + small sizes. Drop us an email to find out more.
Assembled the kit is designed to fit snugly into the top of a pre-prepared aerosol can. It replaces the top part of the can and can be removed easily to replace the battery when needed.
Each can is made + tested by us – discount is available for bulk orders, and we can arrange for shipping discount for low multiples. Each can sells for Â£60 plus shipping via express courier calculated based on your location.
We were working with Matt Venn on a beta version of the FriiSpray software – designed to work with new can hardware. Check out the project on Github and take a look at our wiki. There’s some more info on the last developments here.
These developments are now on the back burner due to issues we had with the more complex hardware and software implementation – all code is available for you to hack yourself.
FriiSpray is a guerilla infra-red graffiti installation developed by the Jam Jar Collective. It uses a custom infra-red spray can, a projector, a Nintendo WiiMote, a computer and open source software.Â The installation is a back projection on a screen or large pane of glass such as a shop front or large window and allows the user to digitally graffiti using the custom made spray can.
Here is a video of FriiSpray in action as part of an animation installation by Andy Sykes at the Leeds Light Night festival in 2009.
How it works.
It works by sending the position (x,y) and on/off signal from a infra-red LED (similar to those found in many TV remotes) mounted in a spray can to the infra-red camera in the front of the Nintendo Wiimote. Â This signal is then transfered via bluetooth to a computer via Johnny Chung Lee’s Wiimote Whiteboard software to control the mouse pointer. Â ThisÂ in turn controls the paint spot in the friispray application. Simple.
The original intention was to recreate a clean form of digital graffiti where the user could virtually spray paint straight on to a window in the centre of town.Â This was partly inspired by the work of the Graffiti Research Lab [GRL] who have created open source forms of expression such as LASER tagging and the LED throwies.Â FriiSpray is free to download and use, the instructions for the 1st infra-red spraycan be found here.
We have since run workshops for various ages and also private party events giving people the chance to try their hand at virtual graffiti themselves.
