Title: TI-Nspire CX dock connector breakout boards
Post by: tangrs on May 28, 2014, 05:22:36 am
Hi,

I apologize in advance if selling stuff is against the rules of the forum.


I made a very, very basic design for a breakout board that's soldered to the CX model (old versions not supported, sorry!). Think modchip but for breaking out the dock connector.

I originally designed this just for myself but the PCB manufacturers sent me 6 extra boards. Unfortunately, they sent me boards thicker than I expected and mirrored my design :( Also, unless you solder some right angle pin headers, you won't be able to close the lid on the back of the calculator.


They're still usable if you do a bit of manual drilling work and a bit of extra patience when soldering. I'd rather see these boards be put to use than thrown away or chucked in the corner.

If anyone's interested, I'm willing to send the extra PCBs for AUD$5 postage (that's about EUR$3.40 or USD$4.60) to anywhere in the world. Add AUD$2 for the matching surface mount pin header but I only have 4 of these left. Please note that is is for advanced users who have de/soldering skills and is okay with opening up their TI-Nspire CX's.

I'll post some soldering/installation instructions if there are people interested.

Selling stuff is OK :) The price is very generous I think so I'm sure you can at least sell 1 or 2 of them.

Cool, I was a bit edgy about posting this since a lot of forums ban this kind of stuff. The price is mainly to cover postage really..

Well it's calc-related so it's probably OK. It'd be another story if you suddenly went to sell viagra random novels.

Why, I had this idea yesterday ! :D I'm not going to get yours though because I'd like to learn PCB design stuff.

I also did this to learn PCB design XD

You can also tell it's my first time doing it since I stuffed up so much D:

Stuffed up ? Do you mean the traces not being parallel to the borders ? :P

Nah, I submitted a mirrored design so everything was flipped and forgot to specify board thickness at order time. Oh well.

I don't know if oshpark allows specifying PCB thickness. That would be useful but it doesn't seem like it.
Edit : nah, they're fixed at 1.6mm

I thought that $5.00 AUD was worth $0.00 USD?? O.O

Just kidding, this is very nice :D. I doubt I would personally get one though since I am not experienced with soldering. :P

Not that you would even need it. :P

As much as I'd like to support calculator peripheral development: I do not own a Nspire so I don't need one of these. It's cool that more people start making their own hardware though!

I don’t think that Texas Instruments would be happy about this

TI isn't happy about a lot of things on this website.

/me pokes Ndless. :P
The calculators we own are our own and we legally can do whatever the hell we want with them. And sell hardware too. So TI doesn't have the right to do anything about it. ;)

I would definitely buy one if you are still selling!
