There are three [[Baytech RPC28A]] powerbars which can be used for fun and infrastructure projects. Each RPC contains 21 IEC 'C13' connectors, the same as you can find on the end of a standard computer cable. We can either hack one RPC to use 'kroonsteentjes', or get some C14 connectors or cables. ==Implementation== Code is written in Python: http://github.com/MerlijnWajer/powerbars A web interface currently runs on http://powerbar.ti/ or http://powerbar.ti:5000/ See the README at the github repository for the API description and general design documentation. It's installed on replicator in /home/techinc/powerbars === Quick fixes === If it becomes unresponsive you can kill the python server and restart it with: <code> python2 /home/techinc/powerbars/server.py & </code> == Proposal == Hardware wise: * Cubieboard * Cables that fit the powerbar sockets. Software wise: * [TODO] Protected ports * [DONE] HTTP (simple protocol), GET/1/1 (Bar 1, Port 1) * [DONE] Groups. Each port by default has its own group, but they can be part of larger groups. * [DONE] Presets * Permissions per group, port... [Don't touch, etc] == UI == Currently the webapp thingy looks like a remote and doesn't efficiently use horizontal screen real estate. We could: * Make the column wider and float:left the forms * Use an imagemap to present the bottons on a floorplan * Perhaps both with a toggle button or by using media queries to determine if the viewport is wide enough for the image map = Old page = Arduino and python code to interface with the thingamagic on [https://github.com/techinc/Baytech github] Unfortunately, the RJ-45 is totally incompatible with the standard blue Cisco cable. So, in the absence of spare DE-9 connectors, I have been trying to make a working serial cable out of junk parts: not handy. In the end, when you know which wires to connect, it is very easy to make a cable to connect a DE-9 serial plug to the RJ-45 on the powerbar. The schematic is below We can either use standard long ethernet wires with a DE-9 to RJ45 socket, which is handy if we would have an infrastructure with a patchpanel, or a dedicated RJ-45 to DE-9 cable. I made the latter. This cable has no RTS/CTS or DTR/DCD control, as that didn't seem to work. {| class="wikitable" style="text-align:center;" |+ Cable layout (using TIA568A wiring) ! RJ-45 !!

There is a separate page to [[Reset Baytech to Defaults]].
