On the right wavelength? (Part 2)

Waiting at the Post Office today were a couple of type-380 60 red LED tail/brake light bulbs to have a play with. I got these from Autobulbs.co.uk in preference to the 92 LED version that needs modifying to fit into the Caponord reflector/socket (thanks for the info Andy!).

To recap on the conclusion of ‘On the right wavelength? (Part 1)’ – In my opinion it would be unwise to fit WHITE LED tail/stop bulbs in the Capo UNLESS you first have definitive proof of the red light output and even then, there is the subject of the legality of fitting them in the first place!

What follows then is a laymans point-of-view of the alternative red LED bulbs after a fun-filled afternoon tinkering in the barn …….So ……. off with the lens cap, pop out a bulb and in with the new …. Easy to fit with no modification, they are certainly brighter than the standard 5w tail lights, while the brake lights are definitely on a par, if not a tad brighter than the standard 21w filament, most importantly the change in output when the brake is activated/deactivated is crisp and very obvious. Of course the one thing you notice electrically, is the wayyyyy lower drain on the battery when braking! Here’s a table comparing the power usage:-

Difference in power consumption

One additional point I noted in favour of the LED’s is actually based on their construction …. the filament bulb relies heavily on the reflector/lens diffusion to spread the light because it only has one fairly focused source of illumination, whereas the LED has 60 independent sources that reflect and refract far better giving the appearance of a much brighter output from ALL of the lens, a more uniform glow if you will!

Oh and one thing I almost forgot to mention about the LED bulb is that all 60 LED’s are illuminated at all times, the activation of the brake light simply intensifies their output, rather than switching on/off additional LED’s as I’ve seen in some bulbs. I think this maintains a much more even and balanced spread of light.

Conclusion …. yes the RED bulbs work as well if not better than the incandescent and of course the power saving is incredible. How they perform when hot and after several hundred hours of use has to be seen. In the end though I do have to wonder about two things; the logic of selling white LED bulbs for use at the rear of a vehicle and the woefully outdated UK/EU legislation in use – for example, using a bulbs power consumption as a measure of its output is unbelievably outdated. Technological change is here and seemingly faster with each passing year, legislators need to move out of the 20th century if they have any hope of keeping pace.

Me? …… I’ll leave them in for a while, just for evaluation off-road you understand. 😉

Caveat: Using LED tail/stop bulbs on the Caponord in the UK is illegal and as such karlb/moto-abruzzo cannot condone their use. They don’t carry an approval marking nor do they meet the brake light power requirements (15-36w) as set down in the ‘The Road Vehicles Lighting Regulations 1989′ ….round in a circle we go …. the very thing we’re trying to save (power) it turns out we can’t!!

Dimmer and dimmer

Aprilia Caponord ETV1000 Rally-Raid Evening over the Gran Sasso .... I switched on the fog-lights to better illuminate the mud and stone strewn road ahead; when it dawned on me that I hadn’t taken the Capo out in the dark for ages, months probably. And here I was winding a path along our troubled road and hopefully onward for a nice little night-time ride all in the name of testing the auto-dimming backlighting!

After getting the set-up working nicely with the old thumb-over-the-sensor routine, it was time to take the old girl out for a spin and see what the illumination was like both in unlit rural and street-lit urban riding. I took the netbook and cable along so that changes to the code could hopefully be done at the roadside.

Aprilia Caponord ETV1000 Rally-Raid .... and over the Maiella. In the end I was really pleased with how the lighting worked anyway, the only change I made was to the minimum brightness – dropping it slightly – so that it’s totally readable without putting stress on my tender night-time vision. Daytime backlighting is, as you would expect fully-on at 100% while the night-time drops to 30%, which with the higher output LED’s (blue & green) is just about spot on.

But ……

And there’s always a ‘but’ …… the two LED’s in the binnacle (Autoswitch & Battery monitor) now stand out as being overly bright compared to the dashboard at night, so, time to work out how to take these signals and pass them through the Arduino and subject them to the auto-dimming code as well, then the whole cockpit area will be sorted at last! 😉

Saddle up and ride out …..

No hour of life is wasted

that is spent in the saddle.

Winston Churchill

Bless him I never had old Winnie down as a biker, but hey if the cap fits …… 😀

Yes the humble saddle, that piece of plastic/metal and foam that can feel like an armchair or a razor blade, or in fact morph from one to the other over the duration of a few hours or minutes depending on the bike! To be fair the Rally-Raid seat is pretty good, if anything just a bit soft for my weight and could probably benefit from a stiffer foam to stop me sinking into it and putting too much weight on the old coccyx.

After 11 years of wear and tear I was thinking about getting them recovered/padded but didn’t much fancy being without the bike for several weeks while the job was done – step into the limelight Stanleybobly, who just happened to pop-up on the AF1 radar with a near-new set of Raid saddles for a painfully decent price. It would have been plain rude not to have bought them!

So now the Capo has a spanking new pair of saddles and I can work out where I want to send/take the old ones for refurb at my leisure – any advice about UK upholsterers always appreciated.

…… and thanks again to Stanley for selling them to me! 😉

On the right wavelength? (Part 1)

What colour is your tail/brake light? Red I’d hope…. or is it really? Take the Capo’s lens cover off and it’s just a pair of common old yellowish 5/21W incandescent bulbs, the red is of course provided by the light passing through the red lens. In fact since time immemorial the only way simple incandescent bulbs were coloured was either by a coloured cover or 380 60 LED bulb being dipped in a coloured dye. Why? Simply that the humble incandescent bulb fires out light at all different wavelengths from infra-red to ultraviolet, so a simple filter is all that’s needed to allow the required wavelengths to pass through.

Now of course we have LED’s…. and these little puppies don’t work the same way. A red LED will generate light in the 610-760nm wavelength – red …… a blue LED in the 450-500nm wavelength, you’ve guessed it – blue! But what about white LED’s? Well they produce red, blue and green light BUT they are dominant in the blue wavelengths and actually very poor emitters in the red – the very colour we need for our taillight!

So here’s the next question….. Do you change out your ‘so yesterday’ incandescent tail/stop bulbs with ultra-trick, smack-up-to-date LED’s? And if so red or white? Well here are a couple of photographs that I hope will help with that dilemma.

Using my old but trusty Nikon D200 I took the first picture with the Capo tail light and an LED torch for comparison. The second picture is exactly the same except this time I added an infra-red filter to the camera. Now the camera is only picking up light in the red wavelengths ……… look at the torch, I think you’ll agree that in the 2^nd picture the torch is most certainly dimmer than the two puny 5w tail bulbs, yet overpowering in the 1^st photo – quite a dramatic difference me thinks!

Now OK, this is just a torch not a pukka LED tail/stop bulb, and yes I concede that not all white LED’s will output the same amount of red light – but how do you KNOW what the output of that bulb you’re eyeing up on Fleabay really is?

Bottom line?

Don’t fit white LED tail bulbs into the Capo, stick with ordinary bulbs. Bummer on the power-drain, but better on the safety side – nobody likes a rear-end shunt……..

…….but what about the red LED version? Stay tuned for next weeks thrilling roller-coaster episode – ‘On the right wavelength (part 2)’. 😉

ACIM (Aprilia Caponord International Meeting) VI – 2014

After thrashing out our diaries for 2014, Jan and I have managed to keep the 11-13th of July free for ACIM VI 2014 – held this year in San Marino (Italy) …… and so the registration has been duly submitted to the organisers. 😀 😀

So we’re looking forward to plenty of pics, video, laughs and good conversation over the weekend in a spectacular part of Italy. We really hope to meet up with some of you over the weekend and finally put a face to a name!

Almost made it to 100K Km

Yesterday was a great day, warm and a smooth running Capo to zip about on …… not so today, no siree Bob. Started her up this morning and that dreaded little EFI light started flashing away. Front coil #1 (code 33) had shuffled off to the great coil playground in the sky.

Before swapping it out, I plugged TuneECU in to get a screenshot of the dwell – reading 0.420 in the picture – definitely dead as a Dodo. Not to worry though, a spare was on the shelf and an hour later the job was well and truly jobbed. Just two things to mention really ….. one, changing that rubber sleeve is a right pain in the proverbial and two, getting the HT lead onto the Amrish coils is even harder! Note to self …. make sure the next spare coil on the shelf is already fitted into a sleeve and has a HT lead attached, that’ll save at least 15 minutes and a book full of swear words! So after 92,413Km the second Sagem coil has been replaced, the first went a couple of years ago, so will the last two make it to the big 100K Km?

Here’s a graphic I keep (laminated) on top of the airbox lid – it just makes it easier to locate the right coil without consulting the manuals. Click for a bigger version.

New ‘Lockwood’ inlay fitted at last

On 4th February Jan came back home with a suitcase fair groaning with all manner of goodies. The most eagerly awaited though, was the pair of new inlays from Lockwood International Ltd. So first impressions?

Excellent! From the textured material to the bleed-free printing, from the fit to the light-transmission …. everything was exactly as I’d hoped. The first thing I did was pop one onto a waiting chassis/board and turn on the lighting – did the text and colour match the light channels? Again, perfectly. Now I could relax, prepare the new chassis and get ready to fit one permanently to the dashboard. To fix it in place I decided to use a general-purpose spray adhesive and did a trial run on an old chassis/inlay to make sure it would be suitable. Everything seemed fine and it was certainly good experience to do a dummy run.

Making sure the chassis was grease and dust free was essential, then masking off the light-channels, mounting pegs and anywhere else I didn’t want spray glue to go! A couple of thin coats of adhesive were applied and the inlay fitted 10 minutes later to allow time for the solvents to evaporate. Perfect! It was now ready to be fitted to the circuit board, but first a couple of modifications to the board/processor circuits.

First the eeprom file needed to be updated for the Futura speedo/tacho, then the code in the microcontroller needed updating for the different (voltmeter) needle calibration. At the same time a couple of modifications were made to the circuits based on insights I’d picked up about Arduino boards from the Internet, also the auto-dimming circuit was finally added for the variable back-lighting, a bit of tweaking with the code – and it was all ready to be refitted to the Capo.

So there I was …. on a wind-swept but warm Sunday morning, dashboard in hand and about to see the fruits of a few months work finally come together on the bike. No doubt the code for the auto-dimming will need fine-tuning, but that can be done without removing the dashboard again – and that’s the line in the sand, right there. Once fitted, I shouldn’t have to remove them again anytime soon …. and that’s a great feeling!

I think that about now would be a great time to pause and say thanks to a few folks who have helped me keep the momentum in this little project. Firstly Jan for her patience and for lugging stuff across the continent for me, to Andy (beasthonda) for bouncing ideas around with me and his interest in the project, to Arvdee in the USA without who’s generous donation of a Futura inlay I wouldn’t have had a template. Last but not least, Clive from Lockwood International for putting the proverbial icing on the cake – thank you all!!!! 😀

Moving along nicely

Just got this photo from Clive over at Lockwood International in the UK, the nice folks who have made my new inlays for the Caponord dashboard. I’ll write more when they arrive …… I can’t wait!!

Reading the current situation

With the new inlay nearly complete and sufficient testing of the modified dashboard to prove its reliability in day-to-day use, it’s now time to move on and complete the next stage of miniaturising the circuit board. The big grey box and wiring loom holding the Arduino Uno stays for the time being, but now it will house the smaller circuit board and Arduino Nano. Once thoroughly tested, the box and loom will disappear as the board finally gets mounted inside the case.

This time around the microcontroller will be programmed differently to speed up the start time and free up more memory space. For that I’m using a Pololu 1300 programming device ….. Something I’ve never done before, let’s hope I don’t fry it! If all goes well, that then leaves me an Arduino Uno spare and it would be rude not to find another Caponord related little job for it! So here’s the next project…..

I’ll be installing the Uno and three of these naughty little puppies along with and LCD screen into the redundant grey case. Self-powered, it will measure current flow through the 30A rec/reg fuse and the two main 30A fuses simultaneously. The screen will then display measured and calculated data as well as storing the data onto an SD card mounted into the display. So it’ll be a data-logger as well!

The idea is to have the three ACS714 devices, wiring loom and a single multi-pole connector under the saddle. The unit will then simply plug into the connector and merrily measure away. A decent battery and memory card should make data logging for 2hrs + pretty straight forward. So watch this space ………

Lights, camera …….. action!

Video on bikes ……. Nothing new of course, it’s been going on for ages. But for what it’s worth, here’s a potted history of moto-abruzzo’s fumbling’s as a videographer.

This pic is probably where it all began, back in 1992 on a hot day in Italy when I was bored. I strapped my analog camcorder to the cylinder head of the 1500 Goldwing and had a fun afternoon playing. The low perspective added drama to the shots and I could watch the front end working in corners …. Well as much as you can corner on a Goldwing! But of course the kit was bulky and not waterproof in the slightest, Sony Video Walkman GD-V800 so once I’d had a play I never touched it again – especially in the rain soaked confines of the UK.

It was 2001 before I used video again. Now working as a full time Motorcycle Instructor I could see the value of using video as a training aid, so I fitted my Triumph Trophy 1200 with two 720×520 colour bullet cams (front & rear) and used a Sony Video Walkman GD-V800 deck to record. The cameras were interchangeable with PIP (Picture in Picture) so one image was primary while the other was a thumbnail in the corner. It all worked very well and I learned a great deal about camera placement, lens choice, filming and editing video from those days. Sadly, when the Trophy was written off in 2005 the video gear just sat in a corner of the workshop and never got fitted permanently again – mainly because no bike stayed long enough until I got the Caponord!

GoPro Hero 3+ Black And that brings me up to date I guess. 2014, a new year and all that jazz, will see moto-abruzzo once again playing with video. Hopefully this time it will add a new perspective to the website and move things in a slightly different direction. After a few weeks of internet-homework, weighing up the pros and cons of some amazing kit, I’ve chosen the GoPro Hero 3+ Black as the camera platform to use. I’m not going to bang on about the camera as a zillion websites and YouTube videos are available to review this kit, it’s enough to say that in comparison to previous kit I’ve used it look fantastic, is a magnitude more advanced and ……. well lets just say I can’t wait to get filming!
