Due to a mistake on my part, the version 2.4 Shift Light boards are missing an important trace connecting pins D2 and D8 on the nano. This results in the INTR "Sens" method not operating correctly.
Don't worry: It's an easy fix.
Anyone assembling the DIY kit will need to perform an additional step if you would like to use this functionality. The Shift Light will still function without it, but only on the "Freq" setting under the "Sens" menu option (default).
The INTR "Sens" option enables interrupt, hardware-based RPM sensing. The "Freq" method uses software based RPM sensing. Both methods have been proven effective.
Thankfully this error was caught early enough that NONE of the Assembled kits are affected - the fix has been applied to all previous and future Assembled Shift Light Kits. Furthermore, the error has been resolved in the EAGLE files so future boards (2.5+) will not have this problem.
I'm deeply sorry for any inconvenience this may have caused.
The silver lining: it's easily solved with an additional "jumper" wire between pins D2 and D8 on the nano. When you've finished assembling the kit, before you mount it within the enclosure, simply cut a small piece of wire and solder it to pins D2 and D8 on the top of the Nano (the side with the USB port) which is basically the very bottom of the assembled circuit board assembly.
Again, I'm really sorry about this. It was a minor oversight on my part, and one that I will not make again. I chalk this up to "growing pains" of starting an online kit business -- sometimes mistakes happen. As I said before, I'm grateful it's an easy fix and one that I'm more than confident can be resolved quickly. To reiterate, I caught this error early in the process, and it I've already applied the fix to all assembled boards that have shipped thus far.
I appreciate your understanding.
The kits are back! Act soon though, supplies are still limited. I'm currently ordering more parts to maintain a higher inventory count to keep up with demand.

On Monday, March 21st, 2016 the shift light kits became available for purchase. In a matter of hours, they completely sold out. That's unbelievable!
Not to worry - I should have additional stock in 2-3 days. If you'd like to be notified when the DIY kits are in-stock again, please fill out the form below and I'll send you an email. I apologize for the inconvenience - I honestly wasn't expecting them to go this quickly.
I will be very busy over the next few days. I will post a demonstration video of the latest shift light software, instruction manual for the kit, additional parts for purchase, and all of the software and schematics in the forums. Stay tuned!
I'm not sure if you noticed ;-) We have a new site to commemorate the launch! Let me know what you think in the comments.
The code updates are coming along. I also received notification that the first production run of boards have shipped! I'll have a week of quality testing and final adjustments, but this is the last piece of the puzzle.
After 2 years of development, the store will go live in about 1 week!! Who would've thought a simple shift light idea (that my friend asked me to make) would turn into crowd-generated, open-source performance product? I certainly didn't.
This is only possible because of people like you. Thank you. I would not have gotten this far if it wasn't for all your support, ideas, suggestions, and improvements.
