automotive section

I think that instructables should have an automotive section  soo people can show upgrades to their cars  or how to solve problems and so on so forth. even if its just a subsection of workshop  a;though it would be better if it had its own place on instructables.

Plastics in the Automotive Industry

This isn't an in-depth tech article or anything but it's interesting to realize just how much the auto industry runs on plastic: http://www.paxonplastic.com/the-automotive-industry-welcomes-a-plastic-future/ I even read that a 3d printed car might be hitting the market as early as the end of this year. Not sure if that's just a rumor but it doesn't seem far off.

Automotive reindeer antlers

Every year at Christmas I put antlers on my car. (Don’t necessarily do the red nose... Rudolf isn’t the only reindeer...) The store-bought antlers were fine on my old Saturn, but they look too puny on the Jeep that replaced it. I’d like to make my own, but they can’t be so tall or so wide that they’re an inconvenience - or catch too much air and break (or break the windows). Any ideas on how to pursue this utterly frivolous project?

led driver automotive

Can I power an AC LED driver with DC voltage, from what I understand the driver controls voltage and current. I purchase an LED light 7 x 1watt , the driver was rated 85 - 265 volt ac input but the seller had written 12 volt DC with grease pen across the printed label. This light works fine so I ordered 7 more like it with same ratings from a differant seller and they only work on 115 - 230 volt. Now I need to find proper driver or ship back to Hong Kong( Grrrr) I have seen drivers rated at 12 volt AC, will these work on 12 volt DC voltage? Thank you in advance, Duncan.

Automotive Power Loss Annunciator

The photo shows what I'm dealing with: a sound module ($2.50 including shipping from China) and an automotive auxiliary power cord (cigarette lighter.) The sound module has a "play" button at the end of the yellow wires. The "black box" has two tasks:                 - detect loss of power on the 12V cord                 - momentarily connect the two yellow wires (as if the button switch had been pressed.) So far I’ve been told that some sort of relay and a timer could be involved, but since I’m not a Electrical Engineer, I don’t know the specifics. I know that in the automotive world, there are big, bulky relays, but I'm wondering if there are relays in the integrated circuit world? I really need specifics like part numbers and circuit diagrams. Thanking you in advance for your help.

need help with 12 volt relays?

I just purchased a set of running boards off of a 2011 f150. they are electronic and i need to wire them up to a set of relays. what i am trying to do is to make it so that when the door is open it triggers the relay and powers the motors causing the running boards to open up, easy enough. but the problem i am running into is that when the door is closed and the door ajar switch is no longer sending a signal, i need the relay to then reverse the polarity so that the motor will then spin the opposite direction causing the running boards to fold back up. the motors on the running boards do have built in stops so i dont have to worry about leaving power to them. i am also finding out if the door ajar switch on my 2004 chevy silverado uses a positve trigger or a ground trigger. any help i can get would be much appriciated. thanks

Need help with designing a simple12 volt timer for an automotive application

Hello all, I have an idea to make a pre-oiler system for my car's engine.  The idea is to hook up a 12 volt oil pump  to bring oil from the pan up to the head to pre lube everything before I start the engine.  This is to hopefully help prevent unnecessary wear on the engine.  I want to have a timer to control the electric pump so that when the key is turned to the position just before "start" that it triggers the pump to start for  approximately 30-60 seconds.  The question is really, where do I start to look  for information and parts to build this simple circuit?  Also, would it need to be hooked up to constant power to store the timing program, or can it be just a simple mechanical/electrical trigger from the ignition to start the countdown? Thank you for your time in advance, -Mike

I Draw Cars

Via Notcot, and because I've been looking out for this sort of thing recently (Roger-X is deciding between design-related university courses), I came across a Kickstarter project called I Draw Cars. It's a pair of guys, design graduates, who have put together an automotive design resource in a moleskine format - industry references, event data, and templates over which you can sketch your own ideas to form part of your portfolio. It looks good.  Certainly the concept is sound. I wonder if others would think so? --------------------------------------------------------- On a related subject, whilst visiting Wales, we landed in a design exhibit at the National Waterfront Museum in Swansea.  Projects were on display from students of the School of Industrial Design in Swansea. I could go through them, but they were all fascinating - everything from a pop-up cup-carrier to a collapsible zimmer frame and a hydroplaning sports car. Instead, I'll list our highlights, in no particular order: An interesting take on wheeled luggage. A "hyper amphibian". A Dyson-branded scooter. School bookshelves. A cool take on Landrover. Hydroplaning yacht. A hotrod. There were others, but they did not display their websites, or have a small pile of business cards for folk to take.  That's their loss, since part of their course covers "self promotion"...

Polarity switching issue, first one to resolve gets a one year pro membership, if answered by June 03 2012? Answered

Ok, here's the issue.  years ago i picked up a wireless remote control kit for automotive use.  It consists of a 12v receiver with 4 sets of colour matched wires.  Basically you can turn on and off 4 devices.  Press button 1 on the remote and a on-board 15A relay activates completing the circuit for one set of wires.  Press button 1 again and the same relay cut outs and the circuit is broken.   These wires are designed to interrupt the negative or ground  side of your accessory with the positive lead hooked up to your power source.  The receivers power is hooked up to the 12v battery.  I even went so far as to open up the receiver and discovered the entire circuit to be potted in opaque epoxy (how rude) so no modding of the circuit sadly... What I can't get my head around is how to utilize this as a polarity reversing unit, or can it.  Now I have messed around with using polarity reversing circuits in a analog style before, I even wrote an instructable on making one with a DIY DPDT switch  Here's the thing, I live in a remote area of the world and do not have immediate access to what most people are used to, so is this circuit possible to be utilized in the manner I am wanting?  I have access to additional standard 4 pin relays if this helps, but not much of anything else. First person that provides a detailed anwser, which results in this working the way how I want, utilizing what I have, by the end of JUNE 3 2012 will receive a 1 year pro instructables membership.  With a possible 3 month pro membership to the one who proves most useful in finding a feasible work around by JUNE 5th 2012.  And sadly using alternate supplies is not an option, "pretend I am on the moon, with no transport available in time". see the pics Note: in the diagram, the green wires are one switch, the blue wires are another.  Their are 2 more sets of wires but these are being used to control other items and are not shown.

Looking for advice on LiFePO4 car battery replacement for SLA

I'm thinking of replacing my 12V lead acid car battery with a DIY lightweight battery based on LiFePO4 cells, but before I dive in I'd like to get some advice...My plan is to use 4 sets of 2 x ANR26650M1B cells in parallel, to give 13.2V output, and high output current, and about 20Ah capacity.(These cells seem to be used in commercial lightweight car batteries, so seem like a good choice.)Now, question 1: Can I just use these 8 cells as a drop-in replacement? With, presumably, occasional balancing out of the car.I think the answer is no: while my initial research suggests that some people are using off-the-shelf LiFePO4 cells in this way, a whole lot more people write about the protection and balance electronics they're using, and I don't suppose they're all wasting their time.Question 2: If Q1 = "No", would adding a balancing and protection module enable the cells to work safely in the car? There are 100A and 200A 4s modules available, so they should be OK with starting current (c. 120A in my case). I guess it's a question of whether it's OK to have such a protected battery pack constantly hooked up to c. +14.4V from the alternator, or whether I need to limit the time that the battery is charged from the alternator.Question 3: is it smarter to use super capacitors plus lifepo4 cells, to enable higher starting current while keeping battery discharging current low? (I started out thinking of combining an RC LiFePO4 battery pack with 6x400F super capacitors, but realised that I could get enough current with the ANR26650M1B cells, and fewer components should mean less to go wrong)

Then it has to stop passing the 12v even though it is still powered (12v is the still being supplied). Once the supply voltage is removed, it needs to reset so that it can pass thru again the next time supply voltage is introduced. I can solder & read. That is about my limit of electrical circuits. Would an IC 555 timer be able to do this somehow? Thanks STEVE.
