Re: Piggy backing on a normal doorbell

Thanks to the usual prompt service from bitsbox I now have a growling Pi that is sending messages through Growl to the PC, I believe that my smart tv also can accept some notifications but the docs are a little opaque to say the least. That circuit worked a treat Pat thank you very much. This weeken...

Re: Piggy backing on a normal doorbell

Thank you for taking the time to draw that up. I hadn't thought of the pulsing which makes sense now you say it. I suspect I'll handle it in software as once I'd got it triggered I'd send my alerts and whatever out and then sleep for a minute or two to avoid multiple alerts (we don't get that many p...

Piggy backing on a normal doorbell

Hello, I've a feeling I should know the answer to this but my electronics knowledge is dodgy/old. I have a very conventional mains powered doorbell (it runs from a 8-10V transformer) - here it is http://www.tlc-direct.co.uk/Products/VE792.html Now, I like the virtually unbreakable nature of the main...

Those funky extra parms in cmdline.txt aren't needed with that new update (everything has been integrated).
Good idea, Just done that Dougie and can confirm that the Concept 2 is working fine.

Re: USB timeouts talking to a Concept 2 rower PM3 monitor

That sounds like my experiences before the new driver. I now do 10 calls per second (I'm getting stroke state) without getting timeouts. What settings do you have in your /boot/cmdline.txt. I also tweaked my copy of pyrow to trap the timeouts so it didn't crash the whole program on a failure - I'll ...

Re: USB timeouts talking to a Concept 2 rower PM3 monitor

It worked for me Dom - I have a Python+Qt clone of the PM3 display running including a Pie chart showing a breakdown of your stroke state (Drive, dwell , recovery). No timeouts at all. No excuses for not cracking on with it now.

That's fine, I appreciate the update. Once Eben realises that a Pi+7"touchscreen+PM3 will make the ideal rowing coach he'll let you have the gadget for as long as you need. He can then have the Pi detect when he's rowing hard and use GPIO to turn a fan on, as he nears the end of the row it can SMS L...

Re: Full FOV preview, 60 and 90fps modes released

Thanks for the replies. I was being a bit thick with the upscaling James. I was just playing back the h264 file with omxplayer and that scaled it to full screen (1280x1024ish) which made the aliasing seem much worse. Playing it back in a 1:1 window looks much better. You can still see the aliasing c...

Re: Full FOV preview, 60 and 90fps modes released

I've had more of a play today and I'm still happy but the picture quality on both 60 and 90 fps is definitely worse than 30 fps at 640x480. It looks badly anti-aliased if that makes sense. It is more than usable so don't take this as a complaint but more of a query as to whether this is expected and...

That does look quite a neat use for the Pi and it'd be interesting to see if it would work with the Pi. I think 'given up' may be a bit harsh on the Pi's USB support.
