Circuitry - Aftermarket and Self Build "Stuff"

When do you ever need 3 flashes?

when i took my lorry test (don't remember for car test, it was too long ago!) i was told that you must give a minimum of 3 flashes. any less may be considered insufficient by the examiner. no idea where this magical number comes from. not sure what would happen if you are driving a renault truck either, where the dash telltale flashes much much slower than the indicators

[Junglist]

Yeah, minimum. I was thinking 3 flashes is often not enough which is why i don't get the need for this function. I got a few pull-out charlies coming home today from daan saaaf. Two flashes, no mirror check or shoulder glance for blind spot and then pulling out in front of me mid-overtake, causing me to have to slam the brakes on in the middle of a manoeuvre. Why does no one seem to understand lane discipline? It's common sense! Grrr!

[Nate]

the 3 flashes thing was for lane changing and pulling out round stuff without stopping. more or less anything else, and i was told you should just switch them on and let them cancel themselves

Keep trawling through ebay US. Ove the years ive seen -

heated seats
adjustable headlights
electric mirrors
seat belt warning light
cruise control
dashes with service light

al the aboive were vw factory parts

also saw a couplle of kstars for the jetronic systems

I like the 3 flash thing, we have them on some of our pool passats, would be better if it could be increased to 4 or 5 though. One less thing to have to think about on a busy motorway.

I've got some schematics that will do one-touch windows, but it involved getting handy with relays and limit switches and stuff.. None of this retrofitting OEM stuff, this is all maplins-special :) Shout or pm me if you're interested.

AAAAAAAAAAAAAARGH (that's my shout, lol)

I am currently investigating ALL the available aftermarket / homebrew solutions to effectively bring the 20 year old sharabang I call Trinny up to date Spec Wise.

Biggest hurdle at the mo' is converting a set of knackered rear lights to LED housed rear lights. The practical stuff is easy, it's getting the right mix of resistors with LED's that proving difficult, along with HOW luminace ratings apply to varying light intensities. e.g. Fogs / brake lights, etc.

[Junglist]

I can help with any electrical stuff you might need (spares/parts/consumables) that's generic/universal like LED bulbs, wiring, switches, relays, fuses, resistors, diodes, etc. Give me a list and i'll sort you out. I buy direct from manufacturers.

[Funky Diver]

Cheers Kieran,

I'll be taking you up on the offer once I have circuit diagrams sorted

Here ya go:



Reset switches need to be micro-switches mounted at the end of the travel. If you're keen stick a thermal reset on the main 12v line as well.

It's a primitive circuit, and could do with refining, but should give you a shove in the right direction.. You'd probably want to design in some form of cancel feature, for a start..

[Junglist]

I have a massive range of microswitches too by the way, just in case talk of them sounded like a tricky hurdle.

[Funky Diver]

Coool.

Will take a butchers and see how it can be improved / implemented, but that's AWESOME, thank you!

[Funky Diver]

For the true geek amongst us... get yer knashers around this site!!

[Nate]

they sell main agent workwear too. mmmmm, nice shirt!

[Funky Diver]

LOL, ideal for the geeky moments... *adopt nasal voice*

"Just going to change my shirt dear... I have some circuits to design" HaHaHa

Bringing this one back from the grave slightly as it's completely related.

Whilst I appreciate most folks will shoot right over to Electronic Injection ignition, I didn't want to do that... but at the same time I wanted to bring the ignition up to date, with simple tuning.

So, for the cost of a vernier pulley (it was actually less including the shipping from America) I am going to be playing with this bad boy...



It's available in a variety of formats, using MAP and TPS sensing, as well as computer customisable ignition mapping.

I'm not going to try and describe it fully... yuou're far better off reading up on it on their web page - http://www.autosportlabs.net/Megajolt_Lite_Jr.

Basics of operation - current Distributor ignition system is "gone" - no longer required. So that's the Coil,Dizzy and points out of the way. A timing wheel is added to the crank, along with EDIS ignition and coils packs from Ford vehicles (most popular) and the box of tricks in the piccie attached to it.

Once it's all hooked up, you have completely controllable 3D ignition mapping, altered via PC.

I'm also going to be supplementing this with a bit of Arduino integration - more on that in the future
