Post by thread:[EE]: Large LED Matrix Displays

Hi, Does anyone know a cheap place (hopefully in the UK) to get hold of some relatively large (say about 60cm x 10cm) LED Matrix displays from? The kind of displays used for 'tickertape' scrolling displays commonly seen at conference centres etc. No need for exceedingly high resolution, multicolour or any other fancy things, just enough to display a line of 10cm high characters, fairly brightly. A quick prod at the RS catalogue only yielded some very expensive units with built in RS232 links & PC based software, a bit of an overkill for my requirements. Cheers, Chris.

It might be as quick to get some strips of Vero board and mount LED's on them. Knock up some shift registers and a PIC to drive it. Else see what is available through hire companies if you are on a short time scale. The ones that do corporate events are likely to have this sort of thing for shows and the like. -- http://www.piclist.com hint: To leave the PICList .....piclist-unsubscribe-requestKILLspam@spam@mitvma.mit.edu

I did think about going the DIY route, however, for 60x10cm, it works out as an awful lot of LEDs and a fair bit of time spent wiring them up too. Not to mention the fact that my DIY electronics projects always end up looking absolutely awful ;) This is just for a personal little project I've wanted to do for a while, (permanent thing, so renting isnt an option) was kind of hoping to pick some LED matrix up off the shelf for around the 30ukp kind of mark - as you say, there's not an awful lot to them if you strip out the control side.

Worth trying http://www.kingbright.com They use to stock a 5x7 stackable 10cm high block. Cannot recall the part number. Also contact JK Components in the UK - Kent (I have no connection with them). They are very good on price, delivery and I found most helpful. I will see if I can dig out the part number.. Connect to appropriate Darlington drivers and your favourite PIC and there you are.... z {Original Message removed}

You could have a look at the junk at Display Electronics http://www.distel.co.uk/ Select OptoElectronics (when the thing eventually loads )then Led Alpha/Num Scrolling Units. The are 13 items - but maybe not big enough for you (although one - unpriced - claims to be 2.37 m long) George Smith -- http://www.piclist.com hint: To leave the PICList EraseMEpiclist-unsubscribe-requestspam_OUTTakeThisOuTmitvma.mit.edu

Unless you want to build from scratch, 'Large' and 'cheap' are mutually exclusive. 50mm high 5x7 matrix modules can be had for about UKP1 in quantity (1.22 in Farnell 100x), but you have to roll your own drivers. Bigger modules can be got, but you may have to go to a franchised distributor to get a decent price - try Kingbright, LED technology etc. Alternatively you can probably pick up a general purpose moving-message display a lot cheaper than in RS and interface to it On Thu, 25 Jul 2002 11:59:04 +0100, you wrote: {Quote hidden}>Hi, > >Does anyone know a cheap place (hopefully in the UK) to get hold of some relatively large (say about 60cm x 10cm) LED Matrix displays from?

I'm amazed that no one else has mentioned this: Try looking for used ones on ebay. I think that there's some surplus there from an old company called Silent Radio. It has PC software, which I have kicking around, and builtin RS-232 capability. If you want to control it from a PIC, then you're going to have to deal with some junk, because there's a CRC embedded in it. A thread on slashdot has the solution to the CRC problem, so you can search their archives for Silent Radio. The post that has the solution is titled something like "solved it" Good luck. - --Brendan -----BEGIN PGP SIGNATURE----- Version: PGPfreeware 6.5.8 for non-commercial use <http://www.pgp.com> iQA/AwUBPUAofAVk8xtQuK+BEQKl9wCgwAIiQdhqK/2TbUlpuSLk3ilg8yAAoJ1P lYM2nS19kmAEXtozqLjGTpgB =aMwO -----END PGP SIGNATURE----- -- http://www.piclist.com hint: To leave the PICList KILLspampiclist-unsubscribe-requestKILLspammitvma.mit.edu

The kind of displays used for 'tickertape' scrolling displays commonly seen at conference centres etc. No need for exceedingly high resolution, multicolour or any other fancy things, just enough to display a line of 10cm high characters, fairly brightly. they are made of 7*5 or 8*8 modules you can find at farnell or radiospares. these modules can be set up to be right next to each other and form a large wall.
