Have you ever been in the situation that you need to store something, somewhere and keep that thing safe from strangers? And have you tried to store food or drinks in summer time, only to notice that all these things get annoyingly warm after some time and you cannot enjoy your fresh cold beverage or snack anymore?
Because of these situations the concept of the IsoLocker came up.
The IsoLocker not only features a safe storage, which access is secure and managable via logins. It also lets you cool the content to a degree you can set from anywhere via web.
It is highly recommended to use the attached blender file with the free software Blender while constructing the IsoLocker because it helps to understand the concepts and it allows you to look at it in 3D.
This project was part of Multimodal Media Madness 2014, hosted by the chair for Computer Aided Architectural Design (CAAD) and the Media Computing Group of RWTH Aachen University. For more Thinking Skins, please check this page: http://hci.rwth-aachen.de/m3_ss14
This project requires two different sets of materials. One is the "raw material", which is basically the stuff for the wooden frame with all it's interior. This will hold all parts of the electronics set.
Different machines will be used while building the IsoLocker. There is a list of needed machines below.
Here you can find a list of amounts and properties for all needed materials. All dimensions are measured in cm. The first value describes the thickness / height of the material.
A Raspberry Pi can be used to control all sensors, actuators and to setup a webserver. Door switches allow to check the current door status, temperature sensors are used to measure and give a feedback about the temperature inside. In case of bad light or nighttime light sensors are necessary to turn on the LEDs. Futhermore RGB LEDs indicate the current status of the IsoLocker and can be used to identify the correct IsoLocker if there are multiple of them next to each other. A buzzer sets off an alarm if one of the doors stays open for too long while the cooling is active.
For the door mechanics solenoids and servo motors are used. The cooling is provided by peltier elements. Aside from that there are also two NFC tags and QR codes for easy accessing the website with your smart-phone on each side of the IsoLocker. Some additional fans are needed for heat dissipation.
Finally to close the electronics part, there are power supply units to power up all that stuff and of course resistors, cables and MOSFETs are needed aswell.
Therefore the electronics used are:
