How to put an automatic car in neutral with a broken transmission? Answered

I have a van that has a broken transmission. I want to take it to the scrap yard to get it out of here. In order to do that I need it to be in neutral so I can move it. When I put the key in and shift it into neutral or any other gear, it doesn't do anything, It shifts smoothly.... not like a normal car. So my question is: How can I shift it into neutral without using the shift lever? Under the hood? It's a chrysler 1999 van

Thunderbirds are go!

Abu Dhabi has started to build what it says is the world's first zero-carbon, zero-waste car-free city.Masdar City will cost $22bn (£11.3bn), take eight years to build and be home to 50,000 people and 1,500 businesses.The city will be mostly powered by solar energy and residents will move in travel pods running on magnetic tracks.Finally, the world imagined by Gerry Anderson is starting to be built - whole cities built as one thing, people travelling on monorail pods, centralised desalination plants, massive hydrogen plants... the chances that they will need International Rescue seem greater with every corner you turn.Still, it could be A Good Thing - if it works, this could be a big stimulus to other nations to start working on carbon neutrality with a vengeance.

Are carbon neutral fuels good for the environment? Answered

I'm sort of confused about carbon neutrality and it's impact on our environment. I feel like I'm over thinking it, but could someone explain to me what exactly makes a carbon neutral fuel clean?

Why have neutral plates in an hydroxy generator? Answered

Hi all, I've been wanting to build a simple hydroxy generator for using it as a torch.  I've seen about 500 gazillion tutorials and alot of them talk abour having 3-5 neutral plates between each positive and negative plate. What is the point of this?  Isn't it better to have all plates connected as electrodes? Also, what's the difference between having 5 neutral plates between positive and negative plate, and just having the positive and negative plates installed farther apart (same distance as if you had the neutrals between them)? Thanks!

Is it really OK to shift into neutral when coasting downhill? Answered

I drive a 92' Dodge Dynasty with an automatic 4 speed transmission. I've read in almost every "fuel saving" instuctable that if you shift into neutral while going downhill, it'll save gas. I told my dad this, excited at the prospect of getting better mileage, and he said that when in neutral, the transmission fluid doesn't circulate in the transmission and it's like the worst possible thing to do. Dad's worked on cars forever, but he learned to work on older ones. I think maybe what he's saying applies to older transmissions or something. Basically, I figure that if it really will cause damage, someone else would have spoken up by now in comments or something. So, please, settle my nerves. I love my car and don't wanna damage it, but I also want better mileage. Is my dad right or is it safe to shift into neutral?

linear input to control a rotating servo? Answered

This model has an intergrated timer (which i do not want to use so i didn't connect up the unswitched live) and is supposed to be run off of a 3 pole fan switch. From my distribution board the cables are going to a switch and from there to the 3 pole fan switch and on to the fan. At the distribution board the live is connected into a 20Amp breaker and the neutral is connected to the main neutral bar. Whenever i switch on the fan the RCD trips.

Which wire goes where (emergency stop button)? Answered

I'm trying to wire up an emergency stop button. Australian power outlets have 3 prongs, active, neutral and earth. My switch has 2 connections, one Normally Open one Normally Closed.  I think I need to have the active line connected to NC (so connected when the switch is in the ON position) and the neutral connected to NO, and the earth remaining connected regardless. This should mean that when it's on the Active line is connected to ground and this the power is on past the switch. When the switch is OFF the neutral is connected to earth and it is safely off (any remaining power in devices connected to it can drain to earth). Am I right in thinking this? or is there something I've overlooked? I am also aware that mains power (240V AC in Australia) is deadly, and not a good idea to play with unless you are a qualified expert. I do intend to have this checked before use, however I would like to have a proper understanding before I go any further. The emergency stop button I have is rated for sufficient volts and amps to use on Australian mains power, and is suitable for the intended use (before a corded drill or circular saw).

Help finding an LED voltmeter? (or figuring out how to use a 3 wire one for this)

For my coilgun/railgun/whatever project I want to use one of those all In one LED voltmeters, however, all the ones I can find are either 2 wire and just measure the input voltage, or 3 wire, and require a neutral ground. That's where the problem lies. I want to use it to monitor the capacitor bank's charging, which goes up to 250 volts, I'd be fine splitting the voltage and using two meters, but to measure it the negative connection is high voltage positive, which means I can't measure the capacitor bank's charging. Is there an LED volt meter (that's not super expensive) that will accept power from a separate source and has negative and positive connections for measuring voltage? If not, how can I work around this neutral ground problem?

How do I remove the shifter knob in my automatic transmission 2010 Buick Lucerne?

I recently became the proud new owner of a 2010 Buick Lucerne CXL, and i'm in the process of customizing a few minor things in the interior. Which leads me to my question. As I think the stock shifter knob is very boring and of course standard-looking, I am attempting to replace it with an aftermarket knob that uses set screws. However, I cannot work out how to remove the stock shifter knob to put the new one in, as it is not threaded like most shifter knobs are. I found on an online forum information about the 2006 edition which suggests that in that model year, the knob friction-fit onto the shift column and all you have to do to remove it is put the car in neutral (with the engine off) and pull straight up on the knob. Does anyone know if this is the same for the 2010 model? ANY help would be very greatly appreciated, as i cannot find any information on my model year anywhere else on the internet, and it is not included in the car owner's manual. Thank you! :-)

added value of raised beds?

My main hobby is gardening. I eat from my garden, 450 m^2, year round, and even have lots of extra space to play around, grow flowers or experiment. I see many new (US) instructables with raised beds, inspired by a popular book (Batholomeuw). It claims to have higher yields, and lower requirements of water, and work. In Europe, we are unfamiliar with this method (unless for elderly or handicapped people). It raises a few questions, but only to be answered by folks having experience in BOTH traditional methods AND the raised bed garden: In normal circumstances, do the claims of this method uphold? Adding the soil mix: 1/3 vermiculite (=clay), 1/3 peat and 1/3 compost. What kind of compost? Where does it come from? About the yearly renewing of the soil|:- again, where does the compost come from? For compost making: Is the household excess sufficient, or does extra material has to be added?? Why are these questions important? Gardening in the traditional way is nearly carbon neutral, unless all physical work is mechanized. But (the concept of) soil ecology is very precious; just covering it and putting this mix over it almost alarms me!

Mains Ground Safety for Power Supply? Answered

I'm trying to build my first switched mode power supply. I'll be using it to drive two 24v 50W heating elements. I don't want to use a transformer. The design I have so far seems to work well in simulations, but I need some advice regarding mains ground. The control electronics will be operated on power from a small transformer. This provides isolation from mains. I've done this a million times.  However, the mains power connects directly to the loop that produces the 24V signal. This is the loop after the FET, containing a diode, inductor, and capacitor. The wire coming from this loop and going to the comparator is where I'm having trouble. This is a voltage sensing wire and carries very little current, and is used by the comparator to produce negative feedback. This feedback loop is what allows me to get 24V from 120V. The comparator is powered by the 12V isolated supply. In order for it to sense the voltage properly, the comparator's ground must be at the same voltage as the power supply's ground. But the power supply's ground is tied directly to mains ground. Is that safe? Am I allowed to do that? In mains wiring in the US, the left notch is neutral, the bottom hole is ground, and the right notch is hot. Neutral is basically ground, except ground is connected to the actual ground and neutral is this mysterious thing I probably don't completely understand. Is it safe to use it as ground? What if the person using this circuit flips the plug over and suddenly the circuit's "ground" is fluctuating wildly between +/- 120V? The circuit may function just fine, but someone using a switch or knob connecting to ground could get a nasty shock. How do I make sure the ground of my circuit is always connected to actual ground? Do I need to preserve the isolation of the control circuitry? I know how to use Gate Drive Transformers for the FETs, but the sense wire for the comparator still needs to have both halves of the circuit with their grounds at the same voltage. Any advice is greatly appreciated.
