Potentiometer knob collet work??

I have a 6.35mm smooth shaft Potentiometer and looking for a knob to go onto it. I've seen the set/grub screw type, i get how they work but worried about slipping. Also seen the collet type but not to sure how they clench down on the shaft. The shaft isn't threaded, as just a groove running along the top of it. Would it work like a conventional collet from say a dremmel tool?

Applying the right finish to a wooden knob? Answered

I was wondering what finish i could put on a shift knob i made out of purple heart. It is something that i will be touching every day, and it isn't light use. At first i was thinking linseed oil, since i heard people use it on gun stocks and stuff that people like to keep natural looking. But my father suggested some sort of wax instead of an oil. He's got some goddards cabinet wax i could try. Also i sanded it smooth and went to 800 grit sandpaper so it is very smooth. I was even wondering if it is possible that it is so smooth that it doesn't accept a finish well. Any and all advice is welcome,

Where to find power knob for Lakewood model 101 box fan

I have a Lakewood model 101 AB box fan that I had in storage for several years and when I took it out to use it, it is missing the rear back power/speed selection knob. It is 1" diam. and needs a small slot in order for it to attach to the post sticking out from the motor. I have spent quite a bit of time searching for this or an appropriate universal knob and I recently learned Lakewood went out of business several years ago. Any ideas on where I can find this elusive part so that I can use my fan? Thank you very much for your help.

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.

Why are these doorknobs warm?

Hello world! I have a random issue that has been stumping my class since it began: the doorknob is warm. No other doorknob there is warm. There are a few other knobs in the room and they aren't warm, so I don't think it has to do with the heat difference. They aren't just a little warm, they are significantly warmer than other doorknobs. I'm in a room full of engineers and none of us have any idea why they're so warm!

How to control a RGB LED with a button or knob?

I would like to create an led powered by batteries that can change from Green to Yellow to Red and off.  I can use either one RGB led or 3 different leds (Reg, green and  yellow obviously) If having a yellow light makes this more challenging, then I can change the yellow to blue.  Do I need a controller? Can I just use wires and resisters? I would like to keep this as simple as possible to start out.  The whole idea is to have someone be able to either turn a 4-position knob, or push a button to change the color of the LED.  I saw another question on Instructables about this topic, but I could not find any solid answers.  Thank you for any help you can provide. If you need me to provide more information just ask. Thanks again.

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! :-)

What is the vernacular to describe an rf transmitter w/rotary knob that turns a servo/motor 1:1?

I'm barely schooled in robotics and RC.  Seems I'm searching for a needle in a haystack without the precise terminology.  I'd like to turn a knob on a remote chassis.  The knob presently turns manually from stop to stop approximately six times.  It meters L/min of air.  Low torque equivalent to about average for volume/bass/treble controls on a stereo. I'd like to be enabled to turn this knob at an indexible 1:1 ratio with a handheld remote transmitter that utilizes a likewise rotary knob.  Once the servo/stepper or other is mounted axially to the chassis mounted knob and powered by a wall transformer, the hand held remote need not be indexed to match it precisely.   1/4 ID hose attaches to the unit and a L/min flow meter is attached to the remote.  Rf would be highly desirable.  If necessary, or practical, I'd go with a wired rotary encoder/controller to accomplish the same.  I'm unable to find either option after a day of searching online.  Fully willing to cannibalize existing products as well.  It's sometimes much easier and cheaper way to go. Thanks

Help with Circuit Board

The effect light below is supposed to sequence the lights on and off, one at a time, in response to music (sound). Well it does that, but not until the input is around 95 - 100 DBs. I'm trying to figure out what to replace so that it responds to sounds at lower DB levels. The left knob on the rear is for sound adjustment (worthless at this point), the right knob is the chase (sequence)speed. The sound is set to max and the lights still doesn't respond until you really crank the music up. CN2 is where the sound and chase controls connect. It's wired, left to right as follows 1 - red from chase knob 2 - yellow from chase knob 3 - red from sound knob 4 - yellow from sound knob 5 - blue from sound knob The pin block in front of CN2 is power and the other block goes to LEDs on the rear of the unit. I'm trying to figure out what I can replace to make this more sensitive to sound input. The mic isn't the issue, I've tried several and even directly wired headphone input into it and still had to crank it up before it would respond. No comments on my soldering butcher job on the back. The red wire is the positive to the mic (which should be in the burned out hole to the left, but it works there - no better, but no worse) Any thoughts at all on what I could play with to make this thing respond to sound a lower levels would be greatly appreciated.

[Answered] Balance Control Not Working Properly?

Okay, I bought an older karaoke system, which I am using as a speaker for my iPod and an amp for my guitar.  As you have probably deducted from that, it has RCA stereo auxiliary inputs and 2 mic inputs.  I plug my iPod into the RCA aux in jacks, and it is sending out a stereo signal.  The cable I use is a special cable originally intended for an audio/video cable for my camera.  It's wiring scheme allows me to use it as a 3.5 mm (1/8 in) male audio plug to the two stereo, RCA male plugs.  I press play on my iPod, and of course music comes out.  The "amp" has a balance pot on it (pot meaning knob).  When the balance pot is centered, the left channel is full volume, but the right channel is weak.  To get the full right channel, I have to turn the pot all the way right, which of course blocks the left channel out.  There is a "sweet spot" around the 4 o clock position that evens out the channels, but they aren't as strong.

Where have all the EE's gone; long time passing......

I'm trying to upgrade the control circuit on my cheap TIG welder. The existing control is a 10k ohm potentiometer, mounted on the welder. It's wired up such that the voltage drop across the pot is proportional to the welders output. Instead of having one knob that controls the output, I want one knob on the welder's panel that selects the maximum output, and another knob ( to be mounted in a foot pedal control) that allows me to select output power from zero up to the maximum value that is set on the panel knob. Seems to me that there should be a relatively simple, elegant solution that gets covered in the second year of an electrical engineering course. Or am I just insane to think that such a thing should be simple? I've tapped out my own social network, and I can't find anyone who will admit to being an electrical engineer. Thanks.

wiring diagram for single phase, reversible, 120 volt motor on a Cutler Hammer 9441H37B "O" controller?

I am restoring a 1935 South Bend 16 metal turning lathe.  The original motor was a three phase 480 Volt reversible motor which was operated by the Cutler Hammer 9441H37B  "O" series controller.  I do not have three phase electrical power at my current shop.  I do have a new 110/220 volt, 1.5HP, reversible motor on hand and would like to control it with the current C/H controller and utilize the reversible option on 110 volt power.  I have wired the motor once and it ran well and reversed, however, the motor heats on one end after running for a few minutes.  It is possible I have either a fault in the circuits or I think it is more probable I have wired the motor so that the starting circuit remains energized which would also cause the heating after a few minutes of operation.  I need to know a method or determining the correct wiring diagram for the combination.   There are six wires on the motor, (T1) blue, (T2) white, (T3) orange, (T4) yellow, (T5) black, and (T)8 red.  There is also a grounding connection which I have connected to the gounding connection of the controller. The controller knob has three positions, left, center(straight up) and right. The continuity of the controller connections is as follows; Left Position of controller knob     Center Position of controller knob     Right Position of controller knob (I do not know whether the left or right position of the knob is forward, since the lettering is worn away)  9             8              7                             9              8             7                    9              8             7  6             5              4                             6              5             4                     6             5             4  3             2              1                             3              2             1                     3              2             1  Knob end  (left position)                Knob end  (center position)                  Knob end   (right position)    Continuity of controller                     Continuity of controller                        Continuity of Controller         7, 8, 6                                                    7, 6                                                     7, 5, 6         4, 5, 9                                                    4, 9                                                     4, 8, 9         1, 2, 3                                                    1, 3                                                     1, 2, 3

home made car heater control help needed

I have a heater control panel from a 2010 dodge journey that I want to use in a custom made kit car. The control knobs are all based upon resistance, no IC's are used in the panel. The fan speed knob has 4 positions, off/low/med/high (only uses two pins on the board connector) The temp knob has 13 positions from hot to cold in which the AC is automatically triggered from the middle position to full cold, and the heat from warm to full hot (only uses three pins, one common and one for each side of the knobs range) The 3 position selector switch (face/bi-level/floor) also uses only two pins. This board is designed for a max of 5 volts, which I already have that instructable for that. But what I need help on is how to make 3 sets of controls for the various knobs. One for fan speed one for the heat/ cold and one for the position selector switch. Im trying to find a way to create a switching action created by various voltages as they are running through the control board, that will trigger 12 volt effects for the fan speed, and a servo for the heater duct changer. The heater knob will need to turn on or off the AC, and control a shut off valve for the coolant heater control valve. But like a RC servo it would turn in relation to the voltage applied. Would transitors work in this case? Any ideas? Id like to get past this and move into the fabrication of the system. But this is stopping me cold right now.

Need schematic: 60-LED analog seconds-only clock

I built a "barn-door" tracker to take photos of planets and stars so that they are tracked (i.e they appear as dots, not trails). See http://en.wikipedia.org/wiki/Barn_door_tracker if you want more info about  trackers of this type. My tracker can be seen in the first two photos here: http://www.tjimaging.com/ted/astro.htm These devices depend upon the user manually turning a knob at exactly one rpm for as many as fifteen minutes. This is (very) tedious, but gets good results. The biggest difficulty is in keeping the proper rate of knob-turning. I use a stopwatch timer and have a pointer on the knob so I can manually match each second as it goes by. This has to be done in the *dark*, though, for obvious reasons! So there's an additional problem of lighting the dial and stopwatch. My idea would be to affix a steady red LED to the end of the knob pointer and to use an analog clock consisting of 60 red LEDs arranged in a circle around the knob. Only one LED would be lit at a time, starting at 12 o'clock position, and advancing one LED at a time, clockwise, and keeping each LED lit for one second. This arrangement would let me simply match the knob's steady LED with the currently-lit one and thus makes manual matching of the "second hand" visually easy. I expect a 555 timer circuit (powered by battery, not A/C, for portability) could handle this task, but I don't know enough about electronics to know for sure. I'd like to keep the cost lower than it would be if an Arduino-based circuit were used. I've also never made a custom printed circuit board, but I'm game to try after building a successful breadboard. I just need a schematic!  Thanks, all.

True Stainless handle

The stainless cabinet handles are manufactured from stainless steel material as they carries better finish as well as durable. Stainless steel is also the favourite material house ware and kitchen ware too. It is also the main choice for cabinet handle specifically for bathrooms and kitchens mainly due to their easily maintenance. Besides the benefits above, the color and finish of the stainless steel handles looks rather good against cabinet background. Wooden, fiber or plastic material. Modern contemporary kitchen design fit very well with stainless steel handles, and there are good selections of styles to select from. Normally it is not economic and easy to change out the entire kitchen cabinet and it is rather costly, so changing the knobs and pulls may be a good way to refresh the cabinet. Besides the decorative function, the cabinet knobs and handles are also useful in a number of ways. As cabinet door go through lots of wear and tear, so they are easily damaged. Their paint and polish can easily drop off over time. Hence the stainless steel knobs and handles are the better choice for kitchen cabinet due to their durability. but in the market nowadays, many distributors will sell SS201 Material handles rather than SS304 handles due to price problems, and SS201 will rust very easy, so if considered the price, there is another alternative choice, that´s Zinc alloy handles or Alu handles or knobs, especially Zinc alloy handles can be processed in many different finishing. Whatever types of knobs or handles you choose, they ought to fit in the theme of the kitchen. Hence do check out the different styles of the stainless steel handles.

Rotary switch w/ direction based contacts??

I'm looking for a specific type of switch... I believe that it must exist, but I have never seen it... I need a rotary switch, where each clockwise "click" (partial turn) makes one circuit momentarily, and each counter-clockwise turn makes a different momentary conection... example with two light bulbs ( L1 and L2 ) connected to each direction of travel, respectively: If you rotate the knob one "click" (say 15 degrees) clockwise, L1 flashes for a moment, as the knob is in motion. if you continue clockwise, L1 will flash at each "click". If you rotate the knob one "click" counter-clockwise, L2 flashes for a moment. if you continue counter-clockwise, L2 will flash at each "click". There is no center-point, so any clockwise travel corresponds to L1, and any counter-clockwise travel corresponds to L2. does anyone know where I could get a couple of these??

As you'll see in the picture, their are holes in the piece of metal where the knobs go, I was wandering of drilling where those holes are would modify the sound of the guitar significantly and if it could be beneficial?
