Post by thread:[PIC]: Propeller Clock

Hi all, I don't know if anyone remembers, but I was making a propellor clock for the flight ops staff at the aero club as appreciation for all the help they gave to get my license. I wanted to keep external things like buttons "inside" so I tried to use the touch switch idea on Byte Crafts page but I couldn't get it to work reliably. I ended up using a couple of QT110 sensors from Q-Prox. You can see in the image below that to set the time or run the clock only requires that you touch the front glass panel where indicated. For something that I though would take a week or so has taken about 5. It is nearly finished thank goodness, here is a gif of the project so far if anyone is interested. http://www.bubblesoftonline.com/prop2.gif -- Best regards Tony mICros http://www.bubblesoftonline.com spam_OUTsalesTakeThisOuTbubblesoftonline.com -- http://www.piclist.com hint: To leave the PICList .....piclist-unsubscribe-requestKILLspam@spam@mitvma.mit.edu

By the time I bought special router bits, timber, glass cut to size, stain and varnish, well.. you get the picture. It was much cheaper to buy and modify one to suit, although it took some time to find one. -- Best regards Tony mICros http://www.bubblesoftonline.com .....salesKILLspam.....bubblesoftonline.com -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!

Briefly, it's a clock with a novel kind of display formed by LEDs on a rotating circuit board. For more information, visit Bob' site (http://www.bobblick.com) which explains in detail how to build one. This is a mechanically challenging project and others have come up with different designs and features. In Bob's site you will find links to some of the other sites that discuss propeller clocks.

This unit can repeatedly scroll thru a message up to 4000 characters long. The message can be set from the host or via the IR keyboard shown. It can also display a continuous message from the host. Many of these units can be connected together and controlled independently from a single serial port on the host. part 2 16681 bytes content-type:image/jpeg; (decode) part 3 318 bytes ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.

Thanks Bala. I was guessing that is what a propeller clock is. Has anyone considered a small photocell/rechargeable battery for power and an IR link for control? Would replace the slip ring problems with low power consumption considerations. {Quote hidden}> > > > I must have come in the middle of this thread. > > What is a propeller clock? > > Briefly, it's a clock with a novel kind of display formed by LEDs on a > rotating circuit board.

They are made in China and aren't available in small quantities. Perhaps someone resells them, but I don't know that.

Your display unit has impressive specs and looks, Olin! Like many others, I will be happy to learn more about this "EyeBall" display provided it doesn't affect your commercial interests.

I'm not going to release code or get into too many details about a customer's product, but there is no harm in asking questions whether I can answer them or not. You can see what the customer says about themselves at http://www.newscanner.com.
