Very true. I am picking up some suction cups this morning and designing a way to mount this to the windshield, or zipties. It will most likely have a replaceable bottom for however you want to mount it.

That would work too, but I have unlimited access to a laser cutter, so this is gonna get fancy.

Sean yours will be ready as soon as the new chip with flash memory comes in. After that I will probably post up a for sale ad. The rules at my work are if I make cash off the 3d printing I have to pay for it, but if its for friends then its free. So I can sell all the parts separate at cost, and if you want it assembled it will be a few extra bucks of my time.

like i said im in no hurry. i have the qstar, this one will just be for toying around with, and i was going to see if i could integrate it with another droid app for my dirt bike expeditions, hard wired into the headlamp circuit. i can assemble it myself, just give me a clue on what to do.

edit- now that im thinking about it, hook and loop probably wont hold on my bike, so a solid mount is a good option. ill probably machine a handlebar mount for it.

Eh, yours is already assembled lol. I just need to test the new chip. I posted some pictures earlier, but the chips are just stacked up in a way that fits perfectly inside the case.

What's the latest on this project?

Any links to recommended hardware to replicate this?

Waiting for another gps chip to come in. Eta another 2 weeks. Then I will have a writeup, cad files, and a little group buy.

Sounds good. I'll probably be in for the group buy

I will probably have magnet, zip tie, and suction cup mounting. With switchable faces.

I'd love to try to build one, but will get in on the group buy as well. Damn man, thanks for doing all this

They are honestly really easy to put together. Group buy will just be parts+shipping+a little for my time to put them together/3d print stuff. I don't plan on getting rich off this. All files will be open sourced too if you have your own 3d printer and whatnot.

So because I'm lazy and don't want to have this 10hz gps laying around, I bought a $2.50 arduino nano to set the gps to 10hz on boot up.

That should work, right?

Yeah, make sure that you only have the TX line on the GPS connected to the Bluetooth, and the RX to the arduino. Otherwise you will get errors with the serial data. It will make it impossible to program the GPS chip over bluetooth but will allow you to program with the arduino and read from the bluetooth chip. I personally am firmly anti arduino, so I would have used something else but either way it should work.

You also have to find the string to send that programs the GPS. I can look that up sometime but my board is at work right now.

Holy hell China can make some damn cheap clones.

Why anti Arduino? I'm not an EE/CS guy so that's just about the only think I can program by stealing a bunch of code snipts from all over the interwebs.
