Time for Version 2.0…<\/em><\/p>\n

After falling over for about 10 hours, I returned to MITERS<\/a> to tackle the last Double DEC’er board and the left skate. I had a few track notes in my head left over from the assembly of Deathblade-R that facilitated faster assembly of Deathblade-L.<\/p>\n

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

I originally was going to put together the experimental Double DEC’er along with two “permanent” ones. Since I didn’t find that necessary any more, only one of the boards will be built out. This time, I started with SMT parts first, then moved onto the headers and through-hole parts. Sidebullets and trace reinforcement were also added while the board was unmounted.<\/p>\n

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

I also stripped the other battery pack and built the power switch harness beforehand, so everything just dropped in.<\/p>\n

The batteries are retained by gravity, and the DEC boards simply drop on top of them and seat with double sided tape.<\/p>\n

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

And Deathblade-L is (mostly) complete. The motors have no connections yet because I’ll eventually have to take them apart to glue the magnets in. I decided to save on that assembly step for now.<\/p>\n

<\/p>\n

This is probably what all 1.2 of you have been waiting for. Behold, test number zero of RazErblades!<\/p>\n

This literally was the first ground test. I had not ridden them around unpowered beforehand, or really tried them loaded on the ground. My unsteadiness and lack of confidence and machismo are evident, but I start getting used to the feel before long.<\/p>\n

Then I broke everything.<\/p>\n

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

Oooops.<\/p>\n

While executing a T-stop from a slow speed, the brazing joints failed on Deathblade-R. Fortunately, I was almost at a standstill by then. It was more embarassing than damaging, and the traction unit still worked.\u00a0 Regardless, this reveals some deep flaws with the design, namely that I don’t have any patience to actually put things together the right way. The brazing on this frame was done very quickly and poorly, with relatively little penetration or filleting.<\/p>\n

As I’m less than satisfied with these frames anyway, and still have a month before Otakon, I’ll probably rebuild them soon. Expect a return to my usual slots, tabs, T-nuts, and standoffs design paradigm. Or perhaps I’ll just run a TIG torch right along the edge of all the joints to melt everything in place.<\/p>\n

In the mean time, THEY’RE ALIVE!<\/strong> Well, sort of.<\/p>\n

  • Remanufacture the frames. I’ll also have the chance to optimize geometries and cavity sizes now that I know how all the components actually fit together<\/li>\n
  • Revise the wrist controller for more controls flexibility. I found out that I would actually like to have the ability to turn on “brake” mode if possible. Fortunately, I have more Lilypad boards.<\/li>\n
  • Wait for the motor magnets to finish the left two motors.<\/li>\n
  • LEARN TO SKATE.<\/strong> This is quite important if I actually want to wield these in a non-idiotic fashion. I need to at least learn how to make my way around on inlines. I intend to do this using<\/em> the RazErblades, since the hub motor design offers minimal drag and I can actually use them as normal unpowered skates.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
