Release V1.1.0


After the big teardown, I did manage to conquer the 1/4 plate steel with the 6 volt rechargeable drill. 4 new 5/16" bolt holes plus a 1.25" big hole for the motor shaft. Re-assembly went well accept for getting the front-sprocket seated back in place - it was very stubborn, and I am afraid its going to be a bitch to take off. Tronbike V1.1.X going to get a 12 tooth to replace the 10 toother. The result of moving the motor 1 inch is now the chain is well clear of the swing-arm pivot - no more slapping or grinding of the plastic protector. I love how the mount paints up with the flat black.

In addition to the mechanical upgrade, I wired in a 12 volt cigarette lighter plug to the DC-DC converter. This will allow me to run/charge all such devices, namely the PDA. I have a small DC-AC converter that I might try as well, creating an earthquake-ready power supply. I mounted a switch for the plug, and placed/squished the plug into the "firewall" near the headset on the starboard side. Once assembled, I can still get access to the plug via the gapping hole left by the lack of a cooling reservoir.

The IPAQ serial cable is "permanently" mounted the to the Alltrax Motor controller. I used a piece of metallic duct-work tape to replace the stock rubber plug, and a male-male 9 pin converter to bridge the controller and cable. I will need to make sure to disconnect the PDA when charging as per Alltrax's warnings.

AS for the software, I ended up building a complete serial test server to validate/verify my client code. It all worked, but again plugging into the actual Alltrax is just not resulting in any useful data. I can only get a flash from the controller when I send a "reset" message. I might need to make another serial capture of the actual code to see if I am missing something in the protocol.

AND so last night very late I put all the fairings and parts on for my commute to work this morning. It ran great, I was more terrified by the traffic at large than anything with the bike. I climbed my first hill, an overpass, at over 30 mph. The bike is still pretty noisy, the small 10 tooth gear is to blame. I am getting concerned 35-40 is not going to cut it, even for city traffic. Again, the 12 tooth will help that, though I love the current acceleration - its like a subway, just whoosh and you are off at full speed. I rode the bike home in the dark without incident, but did note a slight hesitation during acceleration. The cause turned out to be LOOSE WIRES TO THE MOTOR!! I had forgotten to tighten the bolts down. I am charging her up now, I will post the stats to the ride log.

ALSO, we got some press here at Tronbikes.com. We are featured in the Makezine archives. Thank you Travis for letting me know - I thought people usually asked for permission or at least told you when they linked you into something so cool. Anyway its there as is a new section we can call "Press".

Dude, congrats. I thought I should at least let you know, even if you already knew.

Most sites are submitted in, and they post some of the good ones.

As far as the serial cable goes, I'm not sure. I had trouble getting my PDA working... Maybe its something with the Linux port?
