A redesign of the Gallium PCB to accommodate either through hole or surface mount resistors. I used 220 ohm resistors in this build.
The zip file with full gerbers for this PCB can now be downloaded from my site if you wish to get some made at one of the Chinese PCB manufacturers. I had these boards made by JLCPCB (Not a sponsor). Here's the link to the zipped file.
www.bigclive.com/gallium2.zip
If you go to the PCB manufacturer's order page and upload that file as a single zip file, it should show a preview and fill in all of the order details (but feel free to tweak colours as you desire.). Here's a link to JLC's order page:-
cart.jlcpcb.com/quote
A large amount of these PCBs are being sent to random Patreon and PayPal channel supporters as thanks for helping keep the advertising on the videos to a minimum.
I'd like to add these to my shop, but the cost of postage is now so high that sending a kit out would cost almost £9 ( $12) just for the postage. It may be viable to send just the PCBs in minimal packaging, but you would have to source the LEDs and resistors from eBay yourselves.
It seemed a good idea to use my newly acquired flashing blue LEDs in this build. But for home decoration use the best choice is low intensity, plain, diffused LEDs or the slow colour cycling ones.
You can see this panel in use in the background on my recent live streams on the BigCliveLive channel.
Here's the video of the Fast & Furious pre-show that inspired the LED choice.
Let me know if you think they're all individual fixed speed flashing LEDs.

If I were cutting the ends off of those USB cables, I'd cut them with about 6" of length still on them so I could store them and move them around with me for a couple of decades just so I could throw them away a few days before I actually needed them. Thanks for the video big clive.

One side was mildly serrated, just enough so that metals would not slip out of its jaws. Excellent product, I use mine every day.

When I was an apprentice working in a telephone exchange we built something similar using recovered strips of old switchboard lamps and uniselectors (strowager 50 point rotary stepping switches). It worked at 50v, the noise of spinning switches was horrendous and using incandescent lamps and relays it used about 2Kw, We thought it was very hi-tech (by the standards in 1973). It was "done proper" and wired to BT standards, not quite to turing's bletchley park standards ... but it used a lot of similar kit. The panels were "borrowed" and became part of the christmas decs until star wars set new standards.

I built a cube one of these with 600 flashing RGB LEDs, and took it to EMF Camp 2016. It works quite nicely - you get an emergent pattern from the internal oscillators going out of phase, and it's a chaotic system that rarely produces the same patterns, presumably because of thermal effects: higher duty cycle of LED and its neighbours = hotter LEDs = greater magnitude effect on the oscillator period. After 5 minutes or so it turns into a sort of vague greenish-pinkish mess as all of them go completely out of sync, which isn't very appealing to look at, so I ended up adding a little reset timer to cut power for a second and restart the effect. Interestingly a few of the LEDs managed to "remember" their last colour, despite most of them resetting. It's an extremely simple circuit for a very nice effect, especially since the LEDs I bought operate on constant 5V so you don't need current limiting resistors. Just a lot of soldering.

I worked at a major computer manufacturer in the 90s and they had a visitors centre at the factory for when Large Client visited. There was a window showing the data centre. Only thing is servers are very boring. So, they put panels of flashing LEDs under the mesh fronts of the cabinets so it was more exciting. Another company a friend worked at in their reception lit of lights on the floor to represent where in the world their services were being used most. The lights rarely changed so they changed it to a random batter as looked more techie.

Even better: *reverse-mount* SMD LEDs! Those are one of my favourite components~ 😻 e.g.: www.digikey.co.uk/product-detail/en/W%C3%BCrth+Elektronik/156120BS75300/732-11419-1-ND/7316093 They're designed to be used with a PCB footprint consisting of two contact pads either side of a large-ish hole (2-3mm diameter, maybe?), and mounted with the lens of the LED *through* the PCB. This means that the light is seen from the opposite side of the board to the solder pads. I imagine that, commercially, this would let you keep all components on one side of the board but still have LED indicators on the other side, thus allowing the board/panel to only go through a pick-and-place machine once, saving a lot of money, and eliminating potential issues with having reflow SMD parts on both sides. But what's far more interesting to me is that you can use them to have LEDs shining from one side of a PCB *without seeing any of the solder, tracks, LED packages, etc!* While I do enjoy having visible circuitry in some projects - even artistic projects - it can be very nice to be able to hide all of it, and these LEDs give you that option. An interesting twist might be to only have holes drilled halfway through the PCB, giving a very diffused effect (you'd also have to choose reverse-mount LEDs with short enough lenses, though most don't seem to be the full height of a standard 1.6mm-thick PCB). I doubt you'd be able to get one of the cheap Chinese PCB fabs to drill shallow holes for you unless you were getting a lot of boards made and/or you paid them a lot extra, as they obviously could only drill one panel at once (rather than a stack of several panels), and it might require a lot of extra effort to drill holes to an accurate depth (I'm not really sure how those machines work!), but you could order boards without the holes and drill the holes yourself, preferably with a CNC drilling/milling machine, but even one of those amazingly-cheap £200~300 Chinese CNC "engraver" machines would work great for that! You can get a similar effect by just using regular SMD LEDs, or side-emitting SMD LEDs, on the rear of the board, with the solder resist left off (Pimoroni does this on some of their products), but I think the effect would be better with half-drilled holes :)

Micro USB port tip: you can get like a dozen or more micro USB port on little breakout boards about the size of a pinky fingernail or smalle. they're awesome for projects you can tap just the power you can have power and data and you don't have to mess around with a surface mount soldering you have through holes to work with. I have a few projects where I just attached them on for the power supply or in one case I replaced a charging port on a keyboard or another one where I added USB power because the internal power supply died. This also allows you to separate the connector Port from your project which means they are easily replaceable if damaged and a strain relief between the port and your board that prevents damage on it! Anybody who's repaired a laptop power port will understand what I mean!! Although if you're looking for a reliable and sturdy Port I personally recommend going with the USB Mini ports. for some reason they are more durable and usually of a stronger material I've seen nothing but damaged micro ports and most of the USB mini ports I've seen are intact unless you're stupid with them.

Hi Clive. I've built 4 (1ea RGBY) of these and working on number 5 which is mixed. I don't have any USB power banks yet (dollar stores here in 'Murca don't sell many electrics/electronics, I think due to liability considering Chinese-ium construction) so I joined the 4 complete boards in parallel and connected them to my benchtop DC power supply. Having them all lit, I noticed at 5 volts constant those boards only draw 500 to 600 mA depending on how many LEDs are lit at any given time. I also noticed there are differences in the brightness. I rank them as GBRY from bright to dim. Interesting since all of them came from the same supplier you used and all were in factory-sealed bags. Regardless, they still look awesome side-by-side. Thanks for sharing this fun project with us!

That's the correct scale of intensity. The green and blue are gallium nitride with green being at the peak of eye sensitivity and blue being at the extreme end of the visual spectrum. With the red/yellow it's down to the efficiency of the older gallium arsenide technology. There's much more demand for high output red chips for use in RGB displays. Consider getting a beefy power bank from Walmart. They are good value and made to local standards.
