If you follow mark's recommendation and have to hack the light switch or/and the lamp socket, then I recommend the current configuration: PC to Xbee USB adaptor ----(wireless)---- arduino + Xbee shield + Power Switch tail
https://www.sparkfun.com/products/10747 https://www.sparkfun.com/products/10088 http://arduino.cc/en/Main/ArduinoWirelessShield They are also several cheaper relay shields for arduino. http://arduino-info.wikispaces.com/ArduinoPower If you can use a high power LED (instead of a light bulb, no relay required), you may want to look at https://www.sparkfun.com/products/9000 Our you could be even more creative with http://www.tested.com/art/makers/453665-how-get-started-programmable-rgb-led-strip-lighting/ or electroluminescent wire (aka el wire) https://www.sparkfun.com/search/results?term=el+wire&what=products So much fun ahead of you !

Maybe I shouldn't say interlock. it is basically a box with a key sticking out of it. It already has an led in it. The thing is EPICS knows the status of the key so I was hoping to use that.. > ________________________________________ > From: Maren Purves [[email protected]] > Sent: Thursday, July 11, 2013 6:57 PM > To: Gomella, Andrew (NIH/NHLBI) [F] > Cc: [email protected] > Subject: Re: Simple wireless light controlled through EPICS? > > Wondering: can you power a LED from whatever powers the interlock? > (Maybe 'power' isn't the right word here, 'control' would > probably be better) > > Gomella, Andrew (NIH/NHLBI) [F] wrote: > > Yes you are right. I guess I'm trying to find something along the lines of a wireless switch that can be easily integrated with EPICS. This is probably trivial for most, the issue here is I cant really run wires room to room (needs to be somewhat temporary solution) and I have multiple doors that need covering (and little experience with EPICS and hardware engineering) > > > > If it were one door, to be honest I'd probably just put an old laptop on a table next to it and just have it on our local wifi network reading out the PV value to a fullscreen display... > > > > Mark's suggestion seems the easiest to implement, but I'm not sure I can run the wires. The less elegant option is for me to purchase something like this http://www.amazon.com/dp/B000G80V28 and press it every time I turn the x-ray on or off. > > > > Thanks, > > Andrew > > ________________________________________ > > From: Maren Purves [[email protected]] > > Sent: Thursday, July 11, 2013 6:29 PM > > To: Gomella, Andrew (NIH/NHLBI) [F] > > Cc: Mark Rivers; [email protected] > > Subject: Re: Simple wireless light controlled through EPICS? > > > > Maybe I'm off, but IMHO you need a switch (that you plug the light > > into) with a (serial or otherwise) control rather than the light > > being controlled itself? > > > > Maren > > > > Gomella, Andrew (NIH/NHLBI) [F] wrote: > >> The interlock came hardwired into our x-ray controller box. It's value can be read with the asyn stream driver and is a BO variable that reads whether the key is in the armed position or not. I was hoping to use this value to trigger lights on or off. Unfortunately I can't modify anything with the x-ray controller, so I figure there has to be some sort of USB light on the market that runs on serial commands? Or maybe such a specific thing does not exist and requires a micro-controller and some work to make. > >> ________________________________________ > >> From: Mark Rivers [[email protected]] > >> Sent: Thursday, July 11, 2013 6:02 PM > >> To: Gomella, Andrew (NIH/NHLBI) [F]; [email protected] > >> Subject: RE: Simple wireless light controlled through EPICS? > >> > >> How is your interlock done? Simple relays or with a PLC?

It does not need to be bright, even a small LED will do. Basically I'm trying to have indicators on several doorways to show the current status of the interlock on our x-ray source (which is already a PV). > >> > >> In the ideal scenario it would be connected to wifi so that ethernet/usb cables do not need to be run everywhere. I was thinking of maybe trying to get the "Belkin WeMo Home Automation Switch" to work with EPICS, it is basically a power plug that connects to WiFi. But it is probably easier to find some USB LEDs and run cables. > >> > >> I know some beamlines at APS have EPICS controlled lights, so wondering if anyone has ideas? > >> > >> > >> Thanks! > >> Andrew > >> > > > > > > > |
