Ok so I just built a custom led tachometer for my 500 and I love it, I work for a sign shop so I have access to a laser cnc and built the housing from acrylic and bought the led tach display from flea bay but they had it on aliexpress as well for about $13.the wife won't let me back in the garage to take a pic tonight but it'll post one tomorrow. I put some time into building it but materials cost me about $25 total. It seems much more accurate than the analog tach I replaced. Just got really excited and wanted to squeal about it to my fellow riders.

Ran into little setback with it but finally got the pic of it. It's mounted in an acrylic housing I made and I attached it to the triple tree with command velcro straps just in case I change my mind about it.

Just curious, what did you make your tach out of? Was the display already configured for use as a tach?

I have a spare eZ430 target board (MSP430 dev kit) and a HD44780 LCD display and I was thinking of making a tach out of those.

I found this little tach on ebay, it came in a few colors but I thought the yellow would look best for my color bike. I have to admit I had no idea what those parts you mentioned were or how to use them Pardner lol. I'm not great with electrical components but this was a simple 3 wire set up and I just had to swap it out for my analog tach that i had on the bike already.

I only have two issues with it and both are not that big of a deal.

1: In the daytime its kind of hard to see. I can fix this by making a new housing for it that has the display recessed into the housing. Kind of like having it in a shadow box, so to speak

2: From what I can tell its really accurate. This just takes getting used to. The analog tach I had I would get a "rough reading"
as in, "ok, I'm running about 3500 rpms", this one will display for example 3458 rpms, so I just have to re-train my brain to not look at the last two digits.

Its great to see the extra accuracy but for the most part i just wanted to add a smaller tach than I already had and wanted it to be a digital display. I also added a little led voltage display under the right side cover so I can always see where the battery is at a glance.

Wow, hard to make a homemade tach when you can buy one from China for $7USD! So the little tach reads the correct RPM? The reason I ask it because I think the EN500 fires on both the compression stroke and the exhaust stroke... therefore most tach will read double the RPM.

Still cannot decide if I like the digital tach or not, so used to having a simple needle ;)

It has been reading right about the same as the analog tach did. I have always had the bike idle right around 1200 rpm when warmed up and at idle that's what the little led tach shows.
I agree with you that I do prefer the simple needle but I really could not find one small enough.
Something shaped like a half moon would have been ideal but having this big honking tach dial on the handlebars just looked goofy. this is almost identical to what I had on my bike
