Hi Aide, wondering if you'd considered adding a rev-limit warning option to the app.

I'm thinking of three user-definable preset RPM numbers associated with Yellow, Amber and Red. Flash the background with the appropriate colour when the RPM is exceeded.

Greg
That's a good idea - I'll make the RPM dial change background colour (like the ice warning I added to the air temp dial)

Couple of cheeky enhancement requests if you're in the code:

Option to limit the max speed indicator (incriminating) smile
Shift light, eg turn the background red above a configurable rpm

Surprise surprise no clutch fluid. Aaaarrgh!!!

That looks like seal residue in the bottom there.. Did you replace the master at the same time as the slave?

There's always gunk in the bottom of the reservoir, I clean it out with paper towel.

Haven't replaced the master, in fact it's the original. Maybe I should!

Sorry FYP! that must have got lost in the ethersmile

Changing the RPM dial colour is pretty easy, however, I'm going to spend some time this month looking at adding Bluetooth support first.

Great idea for shifting. Audio with it would be even better..

frown I could do with it on Monday and Tuesday while racing other supercars on a runway smile

Not to worry, I'll use the tried and trusted common sense and "if it bogs down, shift up" method smile

okey dokey, quickest way to do V1.0 of this is to have three hard coded thresholds and no audio.
Say 5000, 6000 and 6500 rpm with respective yellow, amber and red dial changes.
What say you all?

I would question the worth of this Aide, i mean who is going to be looking at the screen when hitting these kind of revs anyway ?? Personally i would be watching the road ahead.

I guess it depends where your tablet is mounted. The fact that one is looking at the road ahead and not the rev counter is the very reason for a shift light, especially if it's very obvious (eg whole background changes colour and with audio even better). It would be especially useful for me because for some reason my rev counter stops when it gets to about 6.5krpm frown.

How about 3 colour settings for each of 6.5k, 6750 and 7k? Then we could choose {yellow,amber,red} or {none,red,red} or {amber,amber,red} etc etc

If you were using the HUD this would work fine..

Isn't the rev limit 7.5k+? Wouldn't the limits be better set a bit higher..?

^ agreed smile

Actually a few configurable levels of warning would generalise to most of the gauges, speed, water temp, throttle pots, lambdas, battery etc. Some would need undervalue levels as well as overvalue. Worth bearing in mind when you code it up smile. What language is it written in btw?

That's what the HUD was added for! [that and, if a Tornado has one, then a Cerb has to as well smile]

Let me have a think about it.

I was thinking more along the lines of cutting a "theFrog" release for his Monday/Tuesday fun/hooning smile

I'll then, once everyone gives a bit of feedback, build on it a bit more?

(Oh, it's written using good ol' C-x M-c M-butterfly)

At least your Rev counter works up to 6k5. Whilst mine is OK at all revs, its not if you use WOT then it drops off and bounces around a bit! All componded by being a 96 car which has no change up buzzer fitted!!

One thing to watch out for - having used the app last night to do a bit of testing, this evening the tablet was completely dead. No leads were plugged into it. Looking at the battery monitor, the battery went into a steep decline over night even though the tablet was in standby. The steep drop corresponds to the GPS being active. According to the monitor the tablet was "awake" (unlike me) even though the screen was off.

It was so dead that it took 15 mins charging before it rebooted itself and I was beginning to wonder if I'd killed it smile

The app uses the GPS sensor for the speedo, altitude etc etc and the six axis sensor for g-force measurements.

Both sensors are usually on the same die.

The lifecycle of the app is pretty simple.

If you run it and the screen times out or if the app is pushed to the background for any reason (getting a phone call etc) it ends.

And more importantly, if your android device just goes to sleep the app ends as well.

I did this deliberately so that it only ever consumes resources if it's 'in play' or 'in focus'

So, I rrespective of having RS-AJP installed, other features on your android device can drain your battery - like watching the Game of Thrones box set under the blankets at midnight on a school night! smile
