I thought I understood how you could cut pixel strips but today I was reminded that I didn't completely understand it I have the following strips: http://www.aliexpress.com/store/product/BLACK-PCB-5m-led-digital-strip-DC5V-input-WS2801IC-256-scale-32pcs-IC-and-32pcs-5050/701799_651897346.html I cut them into 1/3 in the process of making a display. I ran into an issue where there were certain pixel sections would light up, but nothing beyond that in the strip would. I found that the particular pixel sections that caused this had some circuitry between the IC and the solder points. It was strange to me because that particular pixel would light up but nothing beyond it would. I'm hoping someone here can shed some light as to what I'm running into so that I at least know why and can avoid or adjust to it in the future. I was always under the impression that you could cut the pixel strips where ever at the solder points and it would never be an issue, but maybe that isn't the case. I've attached a pic for you to see the difference...you can clearly see the additional circuitry. Thanks everyone!
