&lt;hr /&gt;
&lt;div&gt;THIS PAGE IS UNDER CONSTRUCTION!! COME BACK SOON :P&lt;br /&gt;
&lt;br /&gt;
ARMUS, an ARM robotic processing system designed by a team of fourth-year undergraduate students in electrical engineering and computer engineering. This project intends to replace the Handy Board, the current microcontroller system used by first-year undergraduate students in our curricula with a more powerful, versatile and up- to- date technology, while preserving ease of use. Our ARMUS processing system offers high processing and memory capabilities at low energy consumption, for a price of around 300$CAD.&lt;/div&gt;</summary>

&lt;br /&gt;
=== LED displays ===&lt;br /&gt;
&lt;br /&gt;
* [[24&amp;quot; Wall Clock]] A really big wall clock. Why? Well, cause it might look cool? Probably not. But we do use GPS to get the time! Groovy.&lt;br /&gt;
&lt;br /&gt;
* [[POV display]] that spins around, giving the illusion of a large display. ([[User:DavidCary|DavidCary]])&lt;br /&gt;
&lt;br /&gt;
=== [[Cellular Rotary Phone]] ===&lt;br /&gt;
An indepth breakdown of the Port-O-Rotary. Some clues to help you avoid audio problems with the GM862.&lt;br /&gt;
&lt;br /&gt;
=== [[Das Brewmeister!]] ===&lt;br /&gt;
An attempt to wirelessly monitor temperatures of fermentation vessels&lt;br /&gt;
&lt;br /&gt;
=== [[Fermenter Controller]] ===&lt;br /&gt;
A web available fermenter vessel controller. Uses PICs, i2c, Rs232 and python.&lt;br /&gt;
&lt;br /&gt;
=== [[Home controller]] ===&lt;br /&gt;
Program your appliances to operate automatically in conjunction with your weekly and daily schedule, manually turn them on/off from your PC or use the controller as a process ON/OFF controller to regulate some kind of physical variable to the desired value.&lt;br /&gt;
&lt;br /&gt;
=== [[Interactive Lock Box]] ===&lt;br /&gt;

* AFM (atomic force microscope)&lt;br /&gt;
&lt;br /&gt;
=== [[BlueICE]] ===&lt;br /&gt;
A bluetooth JTAG ICE debugger for AVR's!!!&lt;br /&gt;
&lt;br /&gt;
=== [[Sortof-Networked RFID Reader]] ===&lt;br /&gt;
A 125Khz RFID Reader with a simple RS232 based ring network - to allow connection of multiple units to the same control computer.&lt;br /&gt;
&lt;br /&gt;
''Consider using [http://zytrax.com/tech/layer_1/cables/tech_rs232.htm#rj45 &amp;quot;RS-232D&amp;quot;, aka &amp;quot;EIA/TIA-561&amp;quot;]. It has all the same wires and voltages as RS-232, but specifies a RJ45 connector.''&lt;br /&gt;
&lt;br /&gt;
''Also consider RS-485.''&lt;br /&gt;
&lt;br /&gt;
(What is the name of the standard for RS-485 on RJ14 (&amp;quot;4 wire RJ-11&amp;quot;) or RJ45 ?)&lt;br /&gt;
&lt;br /&gt;
