These (http://www.aliexpress.com/store/product/12mm-WS2801-pixel-module-IP66-DC5V-input-full-color/701799_449802558.html ) seem to be a cheap solution for pixels. What do most people recommend as a distance between pixels? [/size] [/size]I realise there are about a 1000 variables that will alter the distance. [/size] [/size]I'm looking at building some arches, mini trees, stars etc. [/size] [/size]I know strips are generally 33mm apart,but being 12mm in size would the ones I've listed be ok at an increased distance?
