[QUOTE="Plan-B, post: 125831, member: 1097"] Quick follow up. I just tried what Pine suggested and connected BI to ground. This made a huge improvement, but didn't rectify the problem entirely. I am now able to turn the current limit up to 2 Amps before I start to see the glitching and flashing issues. If I turn the current limit off and go full brightness, I completely lose control of the strip. I'm still able to access the controller, but the data doesn't seem to make it to the strip and it remains at full brightness until I disconnect the power supply from mains. It looks to me like this is definitely a data signal strength issue. I seems like as the current in the strip rises, it interferes more and more with the data channel. I'm assuming connecting BI to ground somehow helps shield it by diverting noise away? It probably also doesn't help that I have the strip coiled on my desk with the data line running to the center to connect to the input. My noob intuition is telling me that using solid, higher AWG data wiring with soldered connections, a level shifter to boost the data signal from 3.3v to 5v, a resistor to smooth out the data signal and moving the data line away from the coiled strip would probable rectify all my issues and allow me to run the strip at 100% power. But, I'm just not positive all, or any of that is really required and maybe I'm missing something in my ignorance and inexperience. I'm very curious to know what the experienced people of this forum think about the situation. Again, I just want to thank everyone for their time, help and input in this matter. I don't think I could have gotten as far in this project as I have without the support I'm receiving. Cheers! [/QUOTE]

The title of our introductory lighting manual contains a three digit number. What is that number? Clue: Display basics forum
