I've been scheming to build a giant 7 segment LED clock/timer shelf unit for down the back of our church... Normally showing the time of day, but having the timer function for occasions we need to finish at a certain time. Giant size and position down the back is obviously for the preacher to see it, and the shelf design makes it double as storage for the sound/technical team to keep stuff on. Not a unique idea. I got it from someone who 3D printed such a design, but they used addressable LEDs and plastic shelving. I'm going to make it from MDF and probably use these style strips now I've seen them.

@@tin2001 I made mine using styrofoam and cardboard. Sadly I built a hot wire cutter *after* I built the LED clock, so I had to cut the foam with a knife. Cleanup was a chore - little polystyrene balls get electrified and stuck to everything. So, if you want to use this method - get a hot wire cutter. So much cleaner. I used 16-channel constant current LED sink drivers to control the segments without multiplexing (each chip controls 2 digits). I think they were MBI5039 or MBI5036. They work like normal shift registers - you chain them in series, so no matter how many you have they use the same number of pins.

A pretty large 7-segment clock I've recently built (~20cm digit height) uses addressable 5V LED strips that got threaded into the ends of the segments (2 LEDs per end, so 4 per segment). With a "frosted" polystyrene plate (that's supposed to let ~80% of the light through) as the front cover/diffusor I got a pretty even illumination on the segments with just 2cm of depth.

Hi Big Clive! ...... Little Clive here! 👍😂 It's AMAZING how ubiquitous the once humble LED has become! Growing up in the 60's and 70's I'd never heard of them. Incandescent bulbs were used instead. My first encounter with LEDs would have been mid-70's, when I got my space-age Texas Instruments digital watch, and my 1976 Commodore calculator. I no longer have the watch, but the £3.99 calculator, bought from Woolworths 45 years ago, is still going strong! Amazing! I don't think modern life could exist without solid state lighting! Incidentally, thinking about the tech of my childhood, circa 1974, my Dad bought me a Ferguson Stereo Record Player from the Co-op for £30.00! It was powered by Mullard Germanium Transistors! Also incidentally, my 5-Foot LED tube, which I retro-fitted to my kitchen fixture, has almost 500 LED chips I believe. I fitted it about 9 years ago, no failed chips, and it works as good as the day it was fitted! ...... All hail the LED!

Hopefully the diffuser does better than what's on the older style strips.

Nice! Wow, that's not even the densest one on the market if we include 12/24V powered strips, I've found 320/384/480/512/528 led/m variants so far. I though my old 12V 240led/m "95+ CRI" strip was dense - I guess it was in 2019... Obviously the cutting granularity suffers when the voltage goes up though I did find a 12V tape with 25mm between the official cut-points with 320 and 480 led/m (IE 8/12 COB per section). Might be possible to cut it even shorter depending on how they arranged that. Oooh, many interesting uses both for that and this 5V "cut-anywhere" model, but probably need to run them with PWM dimmer that can generate fairly low duty cycles to not get way too bright for many uses. I guess one could also run them at say 10-11V instead - IF they use 3-4 COB in serie (which I expect) that should have a big effect on power draw, not sure how low one can go before they switch to "faint glow" (I'm guessing 8-9V?). Similar things can be done with the 5V though the drop needs to be smaller.

Just bought a 5m roll of this. I still need lights in my van cuz its simply too dark. Hopefully i can fit in such a way it lights up everything neatly

Run some strip on one side and then run speaker wire or lamp wire to connect to strip on the other side of the van. If you got the 12v stuff then you can just run an inline fuse to some 12v wire nearby. Probably best to hook it to the dome light circuit so you just use the same switch to run that.

@@MrMega200 Do you know if it's generally okay to just splice into the existing dome light wires? Or would a dedicated line to the wiring harness be necessary / recommended?
@MrMega2003 жыл бұрын
@@Heizenberg32 I would first check the dome lights amperage and then check the fuse for what capacity that is. Maybe see if you can swap the fuse for a higher rated one to cover for the LEDs if that is possible or else if nothing will work then just run a red wire directly to battery with the inline fuse spliced in somewhere nicely hidden. Be sure to get the mounting crimps you need to fit to the battery positive bolt and to fit a ground line to a body bolt anywhere. The whole body of the car is a negative. Never ever squeeze in some wire to bolts. This isn't a proper connection and is unsafe.

@@MrMega200 Exactly what I did for my car boot (with rubbish light placement). I used about 60cm of it and just wired it to the existing (LED but originally incandescent) boot light (ok I did get the proper connectors to make it a plug in harness thing with no factory wires cut or spliced but that's just me). This stuff is so bright, with 5m of it you'd need sunglasses in there!

Any chance you can put an AM radio next to them to see how bad they are on RFI?

Bare LEDs won't generate much RF noise. It tends to be the power supplies and dimmers that create the noise.

Hang on! 16 mA across 150 R will drop 2.4 volts approximately half the supply voltage. Therefore efficiency of only around 50%. Am I right?

I wonder if they will ever make an RGB variant of the tape. Currently you have to get it a certain color which I guess you could get 3 strips each being one of the RGB colors but that defeats the purpose in my opinion. At least they are pretty cheap, although it would probably be more expensive to buy 3 sets of this than traditional RGB. If you don’t want to change its color then I suppose this would be the cheapest option for the quality. Maybe in a building where the only color you want them to be is one color it would work well, like if you were on a floor that has a color scheme of purple or something. I remember the suits from Tron Legacy used LED strip in them, and they said it worked well with the diffusers because they were flexible enough to be put on a piece of armor like they wear. If they had these back then I bet the detail in the suits would be much cooler because they would have thinner stripes and more control over the designs. I think the stuff that people will make with this will be very cool. I’d like to see it when they make it in the next decade.

i would be curious to see the difference between the 5v and 12v versions of COB tape

12/24v seems more reasonable for something with LEDs packed that dense
