Now that oXigen is here I am finally going to dip toes into the digital world. For the base I have some already routed 3 lane modular sections in 9mm MDF. Once trimmed they will by 90 x 180 cm and 120 x 120cm So in this configuration, length is 4.5 metres, and width is 3 metres. ie, it fits in one side of a double garage. Suitable for schools, churches, rotaract fund-raisers, displays etc. The ordinary driver stations will be along one "base module" straight, and when in analgue mode, it will simply be a 3 lane modular track which can be pulled apart and stored, then reassembled in any desired configuration. We will be using as lightweight a grade of kiln dried dress timber for framing as possible, and all wiring will be tucked away neatly within the framing. I am starting with 6 modules as pictured below. When in analogue mode, the lane changers will simply rest in place for cars to drive straight through in fixed lanes. Analogue timing will be via "cross slot" IR sensors, so there is nothing above the track surface except the barrier walls. A hole in the top surface of one module will have a base plate recessed into the bottom plate of that module, with a short, stubby metal post over which a post of sleeving diameter will be placed holding a timing display screen when assembled. Haven't decided on PC placement or mounting yet. Wiring will be created on the fly as GJH-NZ and I build; - well mostly he builds and I make a nuisance of myself in close proximity when he can't think of anything to send me our for as gopher, chef or apprentice; to as to get some PAQ. For O2 mode timing, I will place some magnets recessed in each of the outer two lanes at track surface level to trigger lap counting, and for pitlane entry (the inside lane will become pit bay) magnets there as well., To move to O2 mode, all that is required is to unplug the controllers, and plug in "dummy-plugs, which bridge out the controller input wire to the output pin of the socket, and thus feed fixed 12 volts DC (or anything from 9 to 30 actually), onto the track. After that, start the O2 software, put cars on track, I.D. them to controllers, and start racing. The modules will fit comfortably in my wife's station wagon, and can be taken to any events we fancy as a club, or for promotional purposes. Running length in this configuration is between 14 and 15 metres each lane going by my rough calcs. Here's a tidier shot, using someone's software to make almost the same design. I am still undecided about location of the lane changers, so very open to advice from digital users. I am almost loathe to put any on corners. (what is the experience of SSD, N-Digital and Scoprius users in that regard, and in terms of length of lane change?) I intend making my own flippers - CAD designed, CNC cut in 5 or 6mm acrylic to be much longer than bought ones, so that lane changes can take place more gently - say 10cm of lane movement over about 50cm of track running length. - Any longer and I thought perhaps the car changing lanes becomes a semi-permanant road block for following vehicles. Someone here Rick? DM? Camber? has built in routed wood, so I am all ears for advice, and even "Doh you thicket, that won't work, listen to me...." Which reminds me, I better go dismantle a lane changer and get the flipper in the mail to my CAD guy.....
