Post by thread:[PICLIST] [OT]LCD for speed/odometer display.

Hello. I want to add a speedometer and perhaps an odometer to my Roller Blades. But I don't recall seeing a hobby source for a short length relativly tall display for showing speed. It has to be big enough to read easily from almost six feet away. I am thinking of something like the display from a hand held multimeter. Does anyone know where I can get those in single quantities, inexpensivly? Thank you.

How about the whole Multimeter. Many of them have a frequency display for your speed(roll your own multiply/divide) and a DAC readout to the DC display for the integrated value.

Hi Russell, most department stores and all bicycle stores sell bike computers, about wristwatch sized or a bit larger with a LCD digital speedo display. I don't know if it's big enough, some are better than others, but that's where i'd look first, they are cheap and have odometer, trip speed averages, etc. :o) -Roman -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.

Anyone remember Andy Warren? Maybe he is still around on this list...but I thought he was developing something like this..commercially of course.????? {Quote hidden}>From: John Ferrell <spam_OUTjohnferrellTakeThisOuTSPRINTMAIL.COM> >Reply-To: pic microcontroller discussion list <.....PICLISTKILLspam@spam@MITVMA.MIT.EDU> >To: PICLISTKILLspamMITVMA.MIT.EDU >Subject: Re: [OT]LCD for speed/odometer display. >Date: Sun, 5 Aug 2001 20:21:15 -0400 > >How about the whole Multimeter.

Yeah, vaguely... > I thought he was developing something like this..commercially of > course.????? Yeah, I did one that was really cool... But between design and manufacturing, the client ran out of money and/or interest, so it's never been made available to the public. Solved the "display must be readable from 6 feet" problem by making the skate transmit wirelessly to a wristwatch display... Which also solved the "I can't keep my balance or see where I'm going if I'm staring intently at the toe of my skate" problem. If you don't mind staring at your toes, there's at least one skate speedo/odometer already on the market that works that way. I don't recall the manufacturer's name offhand. -Andy === Andrew Warren - @spam@fastfwdKILLspamix.netcom.com -- http://www.piclist.com#nomail Going offline?

Dumb question: Since your feet do not remain in continuous contact with the ground while skating, how can you measure speed/distance? Bob Ammerman RAm Systems (contract development of high performance, high function, low-level software) {Original Message removed}

Bob, You measure the MAX velocity during the past second or so and assume that THAT is the current actual velocity. Then you accumulate the sum of the one second interval calculated distances and you have your total distance traveled. Fr. Tom McGahee {Original Message removed}

Ah... a light goes on. This makes a lot of sense, but it wouldn't always work the way I often skate at a rink.... I'll skate along on one foot for perhaps 5 to 10 seconds at a time. But for exercise skating it would work great! Bob Ammerman RAm Systems (contract development of high performance, high function, low-level software) {Original Message removed}
