P. R. Chibikart: The Everything Update + Instructables"},"content":{"rendered":"

Kind of like Kim Jong-Il, nobody really knows when the Democratic People’s Republic of Chibikart was born, or where. I think it was some time on\u00a0 Wednesday, actually, but I haven’t put up an update on it here because I’ve been plowing through the Instructable that I promised pretty much every day since then. This thing is a book<\/em>. It’s 46 Instructables steps long, but each one has on average 5 or 6 “substeps” because otherwise I was facing the prospect of a 200+ step Instructable. But more on that later.<\/p>\n

First, a recap of… what essentially is Wed. night, I suppose. (The prior update which include some of the frame construction is here<\/a>)<\/p>\n

\"\"<\/a><\/p>\n

First off is the electronics deck. Compared to Chibikart, wiring this thing was a breeze. I gave the Jasontrollers<\/a> a well-deserved haircut since I was not using any of their auxiliary functions, and that instantly made the wiring like 10 times cleaner.<\/p>\n

\"\"<\/a><\/p>\n

DPRC features a real terminal block which serves all the power distribution and signal connections, so the plan itself was more open to begin with.<\/p>\n

I do like this arrangement of parts – it’s fairly clean, and the plate is entirely under the seat so you don’t really see any of it from a standing position. The plate can be pushed forward if I ever want to switch to the bigger 500W class Jasontroller, but in my mind this is not really worthwhile.<\/p>\n

If those Jasontrollers look a little familiar, almost like I used them for something else before, that’s because…<\/p>\n

\"\"<\/a><\/p>\n

Poor Chibikart.<\/p>\n

Well, my next batch of Jasontrollers didn’t come on Wednesday, and last time I pledged that<\/p>\n

If they don\u2019t come by Wednesday, I might actually knock two Jasontrollers off Chibikart for now just to get it over with. Because I want to ride it. Badly<\/em>.<\/p>\n

-me, a few days ago<\/p><\/blockquote>\n

Chibikart still runs fine on 2 motors, though! In fact, for a while, it totally did. The acceleration is a little less glamorous.<\/p>\n

\"\"<\/a><\/p>\n

Here’s the electronics deck installed in DPRC with wire extend-o-splices already made. The e-deck drops onto the frame from the bottom – the whole frame is turned over, the e-deck bolted on, and then it’s turned back over to finish wiring the switch and other parts. The seat is off<\/em> this whole time. It was alot more elegant than trying to jiggle all the components while the seat was already covering them, like I had to do for Chibikart1.<\/p>\n

\"\"<\/a><\/p>\n

And here is the completed Pretty Shot!<\/p>\n

This build is way cleaner, and also much lighter<\/em>. We weighed Chibikart versus DPRC, and Chibikart actually weighs almost exactly 50 pounds. This was over my estimates, but Chibikart also has an unnecessarily huge battery and much heavier motors.<\/p>\n

DPRC weighed in at only 36 pounds<\/strong>, with everything<\/em> on it. I swear Melonscooter<\/a> is about that heavy…<\/p>\n

\"\"<\/a><\/p>\n

Compared to Chibikart 1. They’re the exact same outer dimensions and exact same height otherwise. Seeing Chibikart1 weigh so much really makes me want to downgrade<\/strong> the A123 module to some A123 12V7 bricks or the equivalent K2 bricks<\/a>. I do have a few more A123 bricks left over, so perhaps it’s time for an Alphanumeric Battery Company (ABC) shootout with Chibikarts!<\/p>\n

Instructable<\/a><\/h1>\n

As promised in the original mission statement, I’ve finished the Instructable document. In it, you will find the above build progress pics and MANY MANY MANY <\/strong>more. The “Instructable pictures” folder in my DPRC build pics folder has 298 items in it. I don’t even have a word count, but I am positive it is well<\/em> over 9000. I’ve entered it into the “Make It Real<\/a>” contest, because the line of 3d printers in the IDC shop needs expanding<\/a> – either the Objet or the PP3dP Up would be a fun addition to the lineup in the minishop.<\/p>\n

hoonage video<\/h1>\n

This is probably the part that people actually care about – the test video! We made use of the convenient closed loop found in the building architecture yet again. I used Chibikart1 to film a few people driving around the… uhhh…. course.<\/p>\n
