Ok... since this topic is so OT anyway. I have an OLD portable Tektronix oscilloscope that's not working right if anyone's interested. I can pull it down and check the model # if anyone's interested. It's been on the shelf for a LONG TIME. Something wasn't working on the screen. I don't remember if it was horizontal or vertical, or off to the side or what. I remember thinking that I'd fix it someday, and never got around to it... I'm sure the battery is probably shot by now. I think there's a couple probes in the bag too. If anyone is interested, pay for the shipping and it's yours. It might fit in a medium flat rate box ($12.50), I know it will fit in a large (~$17). Of course, these are domestic rates, if someone wants it over the pond, same offer - pay for shipping, but it will probably be more than it's worth... Robert F.

[U2] [way ot] - Electronic Button Purshers?
OK. I'm trying to use a Raspberry pi to push a button, but only want to use one GPIO port. Basically, I'm trying to get the pi to turn a device on or off - and can't easily get to Where the button on the device's board is at to have the pi trigger with a relay, So I plan to mount the device, and have something just push the button directly. Do they make a device that when energized, will push a rod out then back? Right now, my only option (maybe not only), would be to create a Scotch Yoke http://en.wikipedia.org/wiki/Scotch_yoke But for space contraints, and ease, I'd rather put in something that would do That as it's primary function.

Re: [U2] [way ot] - Electronic Button Purshers?
Yeah, that would work as well - once I know it works. The unit I bought actually has an RS232 interface Vs USB - I'm hoping they also supply interfacing documentation as well. I've got a 12/5 volt power supply That was meant to power external 5 1/4 drives - so I'll use that to power the pi, and any other devices. What is nice, is I should be able to remove the batteries from the device as well, and power the BP machine With that power supply. As time goes on, I'm looking to interface in a Pulse Ox reader as well. And I'm Trying to design a medication administration device. Hooked together will import the SPO2 , HR and BP and If acceptable - deliver a medication, otherwise, send an email out. Seems like a nice project for a pi. The hardest part is trying to figure a way to dispense different shaped pills without having to have Some different dispenser for each sized/shape pill. If I use a circular type dispenser, it becomes difficult To store more than a weeks worth of pills (of the same type) in the circular dispenser. Some pills can be 2-3mm and circular in size, others could be 2cm and oblong. I've seen med delivery devices, but none that had any smarts as to not deliver. Should be nice project to learn using the pi and controlling things, as well have something functional That is needed when I'm done. -Original Message- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Robert Porter Sent: Friday, May 03, 2013 12:29 PM To: U2 Users List Subject: Re: [U2] [way ot] - Electronic Button Purshers?

Re: [U2] [way ot] - Electronic Button Purshers?
Have to say, I'm enjoying this line of conversation, too. I did some RD work with a guy who created a PC card that pretended to be RS232, so PICK could drive it, but actually drove a wireless. We did some pretty fun things with that device. It died due to problems getting permission to use a meaningful radio frequency for what they really wanted it for. I believe I have a floppy somewhere (probably not readable any more) with the BASIC code that drove the whole thing. Also have code that drove a Motorola pager from PICK.

Re: [U2] [way ot] - Electronic Button Purshers?
I agree with your approach: prototype the button-pusher with a solenoid to ensure your idea works *before* you tear apart the working hardware -- a normal engineering approach. Be sure to use a diode across the solenoid coil as was suggested elsewhere. If you're unsure of a circuit, I'm sure many of us could provide one if you ask. Good luck!

OK. Nevermind, I got what you mean. Not pull as push/pull, but rather remove. -Original Message- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of George Gallen Sent: Friday, May 03, 2013 12:18 PM To: U2 Users List Subject: Re: [U2] [way ot] - Electronic Button Purshers? ?? not sure what you mean by pull the button? -Original Message- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Robert Frailey Sent: Friday, May 03, 2013 12:12 PM To: U2 Users List Subject: Re: [U2] [way ot] - Electronic Button Purshers? Having a Pi and using it to actuate a solenoid to push a button is like going back into the dark ages with the star ship enterprise.

Re: [U2] [way ot] - Electronic Button Purshers?
Both adafruit.com and spark fun.com carry solenoids that will work and they also have tutorials that'll help. Amazon also has lots of stuff if you already kinda know what you want. If you want things that'll interface with a micro like the RPi or Arduino, just put in a search for 'arduino solenoid' and you'll get a fair number of hits.

Here outside Philadelphia, I continue to seek a parts supplier that doesn't have a $20 minimum order for parts not normally stocked. Even that was from an internet parts supplier, so it's hurry up and wait. Haven't found any other local brick and mortar (outside Philadelphia) stores. If not at Radio Shack, where are you getting parts and skirting the shipping, waiting, and minimum order? ___ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users
