I finished the rebuild of Project RazEr. Because the site has been down, I never wrote up any day-by-day build reports, but still took pictures accordingly.

So, here’s an epicly long build report all the way from start to finish. The whole process wasn’t long and drawn out this time, mostly because the fabricated components were conceptually simple. The majority of work was done in a few evenings at MITERS (as usual.)

We apologize for the inconvenience. To me. Because I have to walk now.

Partial electrical system meltdown combined with salty winter slush means that the electrical system has gone haywire.  As in, something is bridging my battery V+ connection, the frame, and the BEC. That’s pretty intense right there – flipping the power switch to OFF does not actually turn the BEC off. Additionally, I ran down my partial charge, and now have no safe means to recharge the cells.

The underside, and part of the inside by the rear wheel, is also pretty well caked in grunge.

So I’m taking the scooter offline for now, and will be going on a fast rebuilding process. The list of updates include

• One-piece underside attachment that mounts all the batteries and control electronics. On the inside. This means cutting out the bottom of the scooter and using that new underside attachment as a stressed structural element.
• Waterproof.
• Minimize custom electronics. Easier on me, more idiot(me)proof. Plus, you can get a servo tester for 5 bucks now..
• Waterproof.
• Internal battery balancing. Little dedicated balancers are only a few square inches in area and cost 15 dollars. Well worth the extra cost, in my opinion.
• Waterproof.
• All main battery wiring will be heavy gauge, and there will be one charge port.
• Waterproof.
• No-through-bolt wheelmotor design. Can actually change tires!
• Waterproof.
• Stock LiPoly or LiFePO4 packs, not custom assembled jobbles.
• Waterproof.
• External routing of motor wiring. for easier service.
• Waterproof.
• Did I mention waterproof?
