1992 Toyota Paseo (5-speed manual transmission) with difficulty shifting into 1st, 2nd, 5th & reverse?

I have a 1992 Toyota Paseo that's recently started shifting hard into all gears except 3rd & 4th.  We've tried it even when the car's off and it's still having difficulty, so it doesn't seem like it would have anything to do with the clutch.  Weirdly, it doesn't seem to do it all the time. It almost seems like it does it right after it's rained. When it's being difficult, the hardest to shift into is definitely reverse, although 5th isn't always a picnic either. 1st and 2nd are a little tough, but not that bad. 3rd and 4th are smooth as butter. Is it possible for the shift assembly box (or whatever it's technically called) to have some sort of difficulty that could be causing it to stick or be held back in some way? My boyfriend is a mechanic (although he hasn't been able to take it in yet) and he doesn't think it's the transmission, but he's not all that familiar with manual transmission cars. It's got about 160,000 miles on it. Any thoughts?

LED sink driver and Arduino question.?

Hi ... I would like to ask, if I can use 2 of these LED sink drivers uk.farnell.com/jsp/search/productdetail.jsp by using/controlling them just from 3 pins on my Arduino ??? I think, that it should be possible thanks to the pin22 SDO (datasheet www.farnell.com/datasheets/456099.pdf) ... what do you think ??? If yes, is there any limitation on HOW MANY shift registers/LED drivers you can connect "in a row" by using just 3 pins on Arduino ??? Could I use 4 of these drivers and control them just by 3 pins on Arduino ??? Thank you in advance for your answers...zholy

Heating Help!

So my new  major has me in a machine shop that is at my disposal. I have made a few shift knobs but with living in the Northeast it can get cold in the winter months.   I want to heat the knobs, which means finding something that is... - Small enough to fit inside a roughly 1" dia cylinder, depth minimal. - Quickly heat the knob - But not over heat it - Run on a 12v standard supply - Minimal cost I have considered trying to find a "Heating Element" but am unable to find such in a size I need and within a price I want. Maybe a soldering Iron element? I tried "Peltier" but they all are over-sized and debate the conflicting effects of hot and cold. However if figured out I could flip it for summer. I debated running a resistor/other electronic component with just enough power to cause it to heat up, but am worried about it breaking. I wanted to do a high power light bulb, but don't see that working as well as I plan. So I am kinda at a loss...if you have a specific item you can link me to let me see it, or just let me know of an item I can use.

I think I figured out time travel!!!.....sort of :(

I think I stumbled upon the secret to time travel thanks to the thoughts provoked by a previous topic. The secret to it is storage!! as of now time travel to go backwards is to try and get to a place that no longer exists. its like trying to watch last sundays football game but you didn't hit recored on the VCR. As I see it if we want to ever suceed at time travel we need a way to recored and regenerate/exactly simulate life. right now time travel is only possible in minute viewings on recorded video. in order to fully exsperience and interact with life as it was we would need to invent a way to recored the planet and store it for future simulations, ala star trek halodeck. we need to come up with a way to capture life or at least a 3D true to life recording of it. This seems a daunting task but if it were ever achievable we would the be able to experience previous times. if maybe or AI abilities improved we could then apply this to future time travel.... come up with a way to extract information from the recordings we have to generate a logically sound hypothetical projection of future existence. ya, ya.... I know I'm retarded..... but it makes sence to me :p

How to control 100 bidirectional DC motors?

Hi,  I'm trying to control 100 DC motors using a microcontroller (Arduino Mega) The motors run on 1.5V and have a operational current of 40mA. 1) Each motor must be able to rotate clockwise and counter clockwise 2) The motors must be able to move independently     (though direction of the motors at any one time will be the same)      eg. at time = 0; motor 1,20, 30, 45 will rotate CW            at time = 10; motor 20, 35, 80 will rotate CCW 3) Using minimum amount of pins from the Arduino (Shift Register ?) How should i go about doing this ? I have tried using L293D H-Bridge, but in order to control 100 motors,  i will need 50 H-Bridges and 200 digital output pins I'm thinking of a simpler circuitry (image attached) to control the motors. Digital output pins from the Arduino will contol the relay switches, and the DPDT relay will change the polarity of the the voltage supply. Will this work ?  Are there any smaller alternatives to the mechanical relay (transistor ?)  Can a transistor allow current flow in both directions ? I would really appreciate if you could provide some inputs and ideas as to how you would go about controlling a large amount of motors. Cheers!

Phase shifting?

I've been considering building my own ground penetrating radar unit rather than pay outrageous rental fees and mind boggling full prices and I keep coming back to the same problem: time of flight is haaaard. My most recent thoughts on how to go about collecting that data would be to use 2 clocks/crystals that are offset from each other by fractions of a percent(one would be straight from a rubidium standard, and the other from a frequency multiplier). One would be in charge of timing the emitter and the other for timing the receiver. This is the part where I make tons of assumptions about things I know nothing about, so correct me if I'm wrong.      The emitter is running at f1 and it emits a short pulse.      The receiver is running at f2 and collects data as fast as it can until the reflections dissipate.      The emitter pulses again      The receiver, due to the f1:f2 phase shift, is offset by a tiny amount and again collects data as fast as it can. This cycle repeats until the collective phase offsets brings it back around, building the image . My thinking is that this shift, given the time to cycle around, could provide data that is functionally in the range hundreds of GHz, provided the target doesn't move(which at milliseconds per dataset, is functionally true). Could this work?

Shift Register and Relays? Answered

Using a 74hc595 shift register to a ULN2003 darlington array to control 7 relays, all controlled by an MSP430, connected via RJ11.  The relays are controlling LED Christmas light strings on and off.  Everything seems to be functioning so far but the problem is that relays that aren't being told to turn on sometimes are turning on.  The shift register is connceted with Qa to the master reset of the register so I can clear is quickly, but so far I have been just leaving it high.the other 7 outputs (Qb - Qh) connected to the base pins of the ULN2003 (B1 - B7).  The outputs of the ULN2003 connected to the relay coils, COM connected to 5v, emitter connected to ground.  I have tried pull down resistors on the base pins, I have tried tweaking the code which I tried to set up to just bit bang the shift register, make it as simple as possible just to test it and a sample is provided below for one iteration.  I have it looping through several of these to turn a single channel on each time to check to make sure all the channels work.  It however sometime make a channel just flicker, not turn on at all, or turns several channels on at the same time.  I am curious as to whether this is a hardware problem (pullup/down resistors, filtering caps, more clamping diodes then what is built into the ULN2003, whatever) or whether I am just an incompetent programmer.  I am fairly certain the problem lies somewhere between the driver seat and the steering wheel though.  One thought I had but do not want to try right away is it possible the shift register is bad?  Overheated from soldering?  I try to solder one pin on chips, then a pin on another component, then a pin on the opposite side of the chip, etc to keep chips cool when soldering them, but are the 74hc595 very heat sensitive maybe?  Would appreciate a fast answer, looking to build 5 more of these so I can control all my Christmas lights. This was supposed to be a cheap and dirty project so I didn't get into Triacs and dimming, I just want to turn lights on and off as I see fit.   i = 30000;   P1OUT = 0x00;        //Channel 7 (unused)   P1OUT |= 0x02;       //Clock in   P1OUT &=~ 0x02;   //Clock low   P1OUT = 0x01;        //Channel 6 (Green Wreath)   P1OUT |= 0x02;       //Clock in   P1OUT &=~ 0x02;   //Clock low   P1OUT = 0x00;        //Channel 5 (Red Icicle)   P1OUT |= 0x02;       //Clock in   P1OUT &=~ 0x02;   //Clock low   P1OUT = 0x00;        //Channel 4 (White North)   P1OUT |= 0x02;       //Clock in   P1OUT &=~ 0x02;   //Clock low   P1OUT = 0x00;        //Channel 3 (White South)   P1OUT |= 0x02;       //Clock in   P1OUT &=~ 0x02;   //Clock low   P1OUT = 0x00;        //Channel 2 (Blue North)   P1OUT |= 0x02;       //Clock in   P1OUT &=~ 0x02;   //Clock low   P1OUT = 0x00;        //Channel 1 (Blue South)   P1OUT |= 0x02;       //Clock in   P1OUT &=~ 0x02;   //Clock low   P1OUT = 0x01;        //Channel 0 (Clear All/Active Low)   P1OUT |= 0x02;       //Clock in   P1OUT &=~ 0x02;   //Clock low   P1OUT |= 0x04;       //Latch outputs   P1OUT &=~ 0x04;   //Latch low   while(i > 0)   {         i--;   }

Pesky shift registers? Answered

I started working with 2 74HC595N to control 8x8 matrix, and found that instead of a dot it activates multiple rows. So I assumed this was due to my lack of knowledge about shift registers so I setup a simple scenario from arduino ShiftOut tutorial (single register chip and 4 LEDs controlled by number via serial input i.e. "one by one sketch". Thats when I found out that shift register has almost random values on its output pins. Some LEDs were on, some off before I started to controll them. After I turned on/off all 4 it strated to work as supposed to, but last pin retained "memory" of its state even if I reset Arduino.  So my question is, do I always need to initialize every pin of every shift register (and is there an example sketch), or do I have faulty IC? Edit: Added schematic (it's from http://arduino.cc/en/Tutorial/ShiftOut)

Shift Registers vs LED Drivers?

I am trying to figure out how to program an arduino to control LEDs. Basically, what I have done, is I have made a 3x3 matrix and can program some simple sequences with the LEDs using the digitalWrite and delay functions.  I'm not even sure that this is the right way to do this, I don't think it is, but it works.  Anyway I want to try to program bigger matrices and maybe LED cubes using my arduino, but without using up all of the output pins. So, I've came across two ways to get more outputs from less pins; LED drivers and shift registers.  These may be the same thing and I'm just not aware.  But anyway, is there a difference between them? I've really only found information about shift registers, nothing really about LED drivers.  Is one easier to program? Does one use less pins than the other? Or are they just the same thing?

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?
