So very tempted...
 

Been doing a little digging this afternoon.

Come across these websites:

DIY AFR Gauge

http://www.scirocco.org/tech/misc/afgauge/af.html

Thankfully enough, I went onto the National Semiconductor website and ordered some samples of the IC chips used in these, should hopefully get accepted.

If I do, I'll make 1 / both up and see if they work!

Ive got a set of clocks from a Yam MT03 for sale on ebay, which i was goin to try and fit but never got round to it.
Just an idea :-)

Seems like a lot of effort for something that you will not be looking at while you're riding?

? I would.....its a dashboard......

Well, so long as I get these free samples, I'll see what I can put together, hopefully I could put the AFR gauge and Rev counter in the same box, that'd be nice.

AFR gauge is incredibly simple to put together, its just an IC, LED bargraph and a voltage regulator with an input from the O2 sensor which I can hijack from my autotune.

The rev counter is a little more difficult and might require a little ingenuity to get it calibrated.

you crack on with it Daz.....i'm sure you'll get there....

I wouldn't...I don't use a dash.

I'm not saying don't do it Daz, all mods are welcome here. I personally don't find this feature necessary. Good luck with it bud :icon_compress:

Ah, Neither do I!

I don't think its necessary in the slightest, but I need another project to do while my Stage 3 is in limbo mode and what with having my autotune, it'll be nice to see what its reading when im riding and as for the RPM thats just an added feature.

It's just something to do really :spanking[1]:

Oh, and I would look at it, alot!
I like rev counters, they're a novel idea and miss having one on my bike.

I use an analogue rev counter - you can read it with peripheral vision and it is very helpful to me to decide whether I need a gear change for the next section of my goat track.

One thing I love about the XT660s is how many different ways people use them and they still shine.

I'd like an analogue rev counter, in fact I'd prefer that over this DIY one, but I don't see how that'd work on the bike.

Care to enlighten me? who, what and how?

Reads to 16k (perfect for twin-spark pre 2007 XTR).

Numbers don't mean a lot - it is the position of the needle on the dial tells you all you need to know:-

1. No "locate the digits"
2. Focus on the digits.
3. Interpret the digits in relation to the range of interest.
4. Eyes back on road/track pedestrian/goat you've just run over.

Peripheral vision sees the luminous needle in the quadrant which tells you what's needed.

Powered from relay under seat, signal from orange ecu wire, bracket made from builders 'tie' metal tape, waterproof housing included.

(IGNORE _ Company I bought from no longer in business but I think this company sells similar) Mine was �35 two years ago.

Tell a lie - Rspec are still in business. motorcycle tachometer SBM52BLTA-MC

Lol know what you mean mate, been there too :chairfall:

So thats just a generic Rev counter hooked up then?

Looks good to me. I've seen some nice ones reasonably cheap that read upto 8k.

Will have a think on it but thanks for the info :bunny:

Always thought about getting a rev counter but then thought that ive had the xt now for 3 years now and since i have a set of CCC cans i just listen to the engine breath hell out the pipes. Ok im maybe not getting that last 500rpm ever time i want to race a bit but how often do you ever really race a road bike to those sorts of rpms?? not very often.

It's not for Max..ing out - it's to help gear change at appropriate times in my case to keep in the torque when doing v.diff. mountain climbs/descents. I rarely see above 5,000 on my bike (just keep the needle in the upper middle quadrant for pulling and lower left for descents). I missed it sorely when in the Lakes 'cos I haven't got one on Blackie.

I'm only doing it for the giggles and the pwetty colours.

Oh, and my samples have been accepted and sent out so will sort the rest out :D

Quick update!

I've trialed the LED Part of it on my breadboard, works a treat and can set it pretty much to go from nothing to full between 0-2v and 0-6V input signal so hopefully it shouldn't be much more hassle from there.

(as in, I can set it so that all the LEDS are on at 2v, or upto 6v any anywhere between)

AND

I've had a play with the frequency to voltage generator this evening.
It's a real clever bit of kit. Been using my computers audio out to generate a frequency between 10hz upto 67 hz.
Funnily enough, it actually works! Wrapped a piece of wire around a phono lead and put a ground to it, so long as theres enough mV on the input, if I turn the frequency up or down the LED I fitted on the output of the voltage generator gets brighter or dimmer.

It's a clever bit of kit and can see how it'll controll a bargraph.

Will keep on chuggin' :hiding:
