t-trak command/control module set

thingiverse

This is a pair of T-trak modules designed to provide command/control and power districts for a T-trak layout. The modules are engineered to be back-to-back with tracks insulated in the middle by two sets of feeders, resulting in four power districts with the command/control splitting things evenly. When building this project, several goals were kept in mind: - Module format should be easy to transport - Sitting on a table top as a conversation piece - Providing rail power and east/west cables, with the module situated in the middle to reduce bus lengths - Creating power districts to aid in troubleshooting - Offering plenty of visual status options, including voltage/amperage displayed in front and all status lights above-table - Serving as a base for a mast that features wireless options along with a decorative crossbuck/lights Components used and notes: - The front is designed to accommodate a Digitrax UP5 or similar for throttles and a RRampMeter for voltage/amps display - The left/right rear on top are designed for booster/command and circuit protection area (Digitrax DSC240 + BXP88 are being used) - Two track main and programming track in the front - A skyboard is permanently attached due to the amount of holes in the back, with extras mounted there (a Pi and USB router are being mounted) - The back features 2x 40mm fans for cooling, three power pole outlets for east/west power and 12V power, and a grommet for sister module pigtals and AC cord - A 12v 20A power supply will be mounted underneath, tuned to 14v, along with whatever distro blocks are preferred - A metal threaded pipe flange is being installed in the center/top area for wireless/decorative mast - The sister module needs the same double-feed track lines that are insulated in the middle to create power districts; there are three outlets on the back of the sister module for east/west power inputs plus 12V power input. A double crossover, mostly already gapped with feeders added on the ends, will be used. Update 9/5/17 - several pics of cut parts test assembled were uploaded. Update 10/11/2017 - assembling final product now... found that since large wood blocks are glued in for feet in the corners, fan holes get covered; therefore, I'll use the "sister" back on the power module and cut a fan hole in the top instead. These modules are also about 5mm too wide (they're the exact width of trackage), which I believe was due to using a lower powered laser making two passes, not cutting thick enough, or perhaps some graphics file conversions.
