https://stream.echo6.co/videos/watch/1bf22fca-5481-4b00-b5e9-27cc54aba6d6 I've reworked the PCBs for a past project on my website for making custom fixed message signs. For a while I sold the PCBs in my website shop, but even then the cost of international postage was so high that it wasn't viable to sell them due to the combined weight of several PCBs. With easy online small-batch PCB manufacturing, where the circuit boards are made on demand and shipped directly from China, the project has become viable again. Albeit that China gets all the spondoolies. Although the original PCBs had a matte black resist on both sides, with dark red screen print to make it less visible in the finished sign, it will add a huge amount to the cost of getting a small batch made. It's only viable to go for black PCBs if ordering hundreds so they go through as their own batch. That said, the green PCBs with white resist can be spray painted in your chosen colour, and the screen should still show as a raised outline. If spraying them, it makes sense to fit the resistors on the back first to avoid scratching the paint when trimming the leads on the front. Spraying in light coats shouldn't block the holes. The new PCB files have smaller holes for the resistor and round LED leads, and a facility to use wire links on the back of the PCB to loop power between them. The signs are designed to be run from a 5V USB power supply. Try to use good quality supplies and don't load them to their full capacity. You can use several on a big sign. Batteries are also an option, including two or three cell AA packs fitted with NiMh rechargeable cells. The choice of resistors and power supply will determine the sign intensity and run time from batteries. My reference to low intensity outdoor signage was relating to nighttime events. You can find the files at this page, noting that they haven't been tested at the point of making this video:- http://www.bigclive.com/freebies.htm If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- http://www.bigclive.com/coffee.htm This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
