Uber simple HUD reminder thingy

**bogan** · 4th December 2011, 11:57

Programming and testing the boards this weekend:

Audio warning works, but I used the wrong diodes so requires max volume, getting better ones is an easy fix. Blue LED
Indicator warning set for 15 secs, takes either a pulsed active low or high input. Yellow LED
Shift light works on the bench tester, and RPM setable between 8k and 25k by a trimpot. Red LED
Oil light works on an active low signal. Same RED LED as the shift light
Green LED on active low signal.

I'm considering making the green active high, and if you need multiple warning for either active low or high, just diode the signals together on the one light. But most bike stuff I work with is active low anyway, is the modern stuff the same?

Still have to make the LEDs dim at night, but the light sensor works good so should be easy enough. And put in some power saving measure, and change a heap of resistor values, tiny little 0603 format (3x1mm-ish size) just for fun

Pseudonym, that would work with current hardware I think, but would require different firmware and testing, so be an extra charge for that.

I'm still trying to work out the base cost, have a better idea once I get the cases sorted, and get a better idea of how long it'll take to assemble these things.

No rush but don’t forget me!

With the temp warning I’ll just take a feed off the fan relay, it fires in at 103c but it only usualy triggers in traffic, so it’ll be a constant systems check for that circuit.

I do love my gadgets…

Would love a HUD that displays speed and revs, but it amazes me how many people "need" reminding their indicators are on.

How often do you check your speed/gauges?

Your bike could be overheating with a warning like flashing next to the indicator that's been left on, but since you never bother looking down you never notice?

Even on a straight flat road I check the dials on a regular basis.

It kinda sounds like saying I need a HUD to display what's in my mirrors, as I never get round to checking them.

My old bike never had an idiot light, so it was kinda hard to see it flashing, but I have a habit of pressing the indicator button every god knows often haha

And that's a good habit to have learned. And you did learn it.

As for "need"? If someone offers me a device that means I can develop the habit of keeping my eyes on the road more of the time then I'd say that's got to be a better habit to have, eh?

And if it means cleaning up the front of the bike a bit, that may be a good thing too.

More programming this evening, got a low voltage detector in there now, and auto adjust brightness. Not sure if the LEDs are going to be bright enough, as they are approx 2V, so the voltage dropped from the batteries might significantly affect the brightness. Then again, it draws SFA current, so the batteries may hold good voltage for most of their lifetime, which should end up being over a year.
Will see in testing later this week anyway, plenty of room for some 3mm through hole ones if they are required though.

Basically, never, don't see any point... My bike isn't going to magically overheat, I can't legally red line it in any gear, and I don't particularly care if I'm not sitting exactly at or below the mandated speed limit.

All that time you're fucking around looking at your gauges, that's time you're not watching for fuck heads that want to kill you, good luck with that.

Totally agree!

....but!, The NZTA & the "revenue collectors" would seem to prefer you to be paying more attention to your speedo than the road! (Just look at 5kph restrictions on holiday weekends!....watch that speedo!....not the maniac doing a uturn into you!)

I would rather pay a fine for going 5k over the limit...than pay the ultimate price for not being focused on the road and surroundings

I've never been given a ticket for speeding I didn't deserve; I well know when I'm breaking the speed limit without having to continually double check my speedo. I'd wager that most riders have managed to raise their skill level that far at least.

Totally agree. Keith Code says you have only $10 of attention to spend at any one time and you can't afford to waste any too much of that money looking at your speedo.

On the indicator reminder side of things....And I have to declare an invested interest here!

We have sold a stack of the Stop-its!. They are a N.Z. made indicator reminder. Very simple and have they have proven indestructible and impervious to weather and vibrations, etc. They will fit any motorcycle regardless of whether they use electronic or older style indicator relays. Typically take about 20 minutes to fit with a cup of coffee in one hand.

They definitely comply with the KISS principal. I originally just designed and built the first prototype a few years ago for myself because I kept leaving my indicator on (partly because the indicator on that bike took a particularly firm push to cancel) and I would occassionally have cars pull out in front of me because they thought I was turning.

Every car driver can hear their indicator, so I thought it would be good if I could hear mine as well. I then got asked to make a few for friends and the Stop-it!s have now been one of our best selling products over the last couple of years.

We get orders for them from Australia, the UK and elsewhere but strangely are yet to sell any to Italy or India...go figure?

For those of you whom want a mega awesome HUD, and have enough money to buy fancy new stuff there is this......

Now let Bogan get back to work finishing his nice simple (and CHEAP) one.
That is all.

Can I have a voice activated machine gun with mine?

**bogan** · 23rd January 2012, 15:53

Should be getting back into this a bit more now, on to helmet case number two so I can fit some brighter LEDs in it. Some other small changes to make when I get time. Price will be an even hundy, including postage, batteries (should be good for >1year), helmet adhesive, wiring instructions etc...
