Slip Ring - 12 Wire (2A)
This is a 12 wire slip ring, a remarkably simple electromechanical assembly that allows electronic signals to be passed through its rotating innards. Commonly, you’d find slip rings in wind turbines, radar antennae, or anything else that requires continuous 360° rotation while maintaining an electrical connection. This particular slip ring provides you with a compact body with gold-on-gold alloy fiber brush to plated ring contacts inside. Each Slip ring is capable of handling a continuous working speed of 250RPM, a current rating of 2A, and an operating voltage of 210VDC / 240VAC. We aren’t k..

Eagle Text Reference Board
If you’ve ever played with Eagle PCB, you know that silk screen indicators are one of the most important aspects of your layout. We created this board to illustrate various text sizes and ratios (text width). You may use size 0.020 text with a ratio of 8% on your PCB layout, but as the reference board demonstrates, you really can’t read it. We also included various drill sizes and trace widths but they are not completely accurate - the manufacturer increased the really small trace widths to avoid DRC violations. This is a great board to quickly determine the best size and ratio for text, drill..
