Need hobby motor help

I'm a bit clueless about the technical side of motors. I mean I know how they work and I know torque and speed and whatnot, but I'm looking for certain motors with a certain amount of torque. I'm looking for a motor than can lift approx. 20 pounds plus itself and 3 other motors that have equivalent amounts of torque. I have no clue what the Stall-torque rating is or how it's measured, so a crash course in that couldn't hurt, either. Help?

Need hobby power supply.. Reccomendations?

I think its time that I invested in a good desktop variable power supply for building circuits and such. I have one currently, but I'm borrowing it from our school because they have a few extra and don't mind it being gone. But as the school year closes, I am going to have to return it. So any recommendations for a variable desktop supply? My budget is around $100 USD. Thanks!!! So far, looking at some of the ones from google, I like the looks and specs of this power supply.

3V Hobby Motor in a 6V Circuit.

Hi. Hope I'm posting appropriately. If not, please forgive an older guy! I'm working on a Useless Box project that I power from a 6V wall wart. I've already completed one and it works great. I use two standard servos with an Uno. But now, rather than being satisfied, I'd like to add a 3V hobby motor, which naturally would only run randomly for short periods of time. I have purchased an AMS1117 step down module which is rated at 800mA from Amazon to get the correct voltage for my little motor. My question is, do I need to add a capacitor across the leads or to the casing. If so, how do I determine what size? And while I'm asking, is there anything else I need to think about? I appreciate any help as this is a new hobby for me.

When I examined the wiring in the power supply I noticed there is no "green" wire that is used by the computer to turn the power supply on. In your conversion this green wire is connected to the a black ground to wire fire up the power supply. My question: What wire in the Dell power supply is used to fire up the power supply since there is no "green" wire? Is there any special wiring procedures particular to Dell that is different than the standard power supply?

Best way to sell small motors on Ebay, or other site? Answered

I have several small DC motors.  I would like to auction them on Ebay. I'm pretty sure they are all permanent  magnet motors. 3 are stepper motors from printers, and two are carriage motors from printers, and I think I got 2 little motors from an old 3.5" floppy. Should I sell them as one lot, or group them in their different types? I've pretty much figured out that selling them separate isn't going to give anyone a very good deal. Anybody have any luck with this kind'a stuff? Are there better options than Ebay, for these kind of items? Any help/advice would be appreciated! pb

Hack your Servo V1.00: Make a powerful linear actuator using a standard hobby Servo

Hack your Servo V1.00: Make a powerful linear actuator using a standard hobby Servo   Provided you have the tools and the servo you can built this for under a couple of bucks. The actuator extends with a rate of about 50mm/min. It is rather slow but very powerful. Watch my video at the end of the post where the small actuator lifts 10kg vertically.   Materials List Tools list   - hobby servo - standard hobby brass tubing             -OD: 4.0mm, ID: 3.4mm             -OD: 5.8mm, ID: 4.5mm - standard hobby styrene tubing                                                 -OD: 4.8mm, ID: 3.5mm - M4 studding - 2 x M5 washers - 2 x M4 nuts - 5 minute epoxy - cyanoacrylate - grease - multi-strand cables - heat-shrink tubing   - standard tools – screwdrivers, scalpel, files etc. - dremmel multi-tool with ceramic abrasive disk, or similar - hand-drill + 4.9mm + 2.5mm drill-bits - M3 tap - M4 tap - soldering iron - glue gun - small vice - small saw - sanding paper (relatively fine) - small flame torch Procedure - I will be giving instructions based on the dimensional parameters of the Hitec HS-300. The procedure remains the same for any type servo. I strongly recommend you read the whole post before you start. So lets make a start, shall we?   - Open your hobby servo, remove control electronics, feedback potentiometer and mechanical stop on the servo’s output gear.   - Solder new cables on the servo motor’s leads.   - Drill two 4.9mm holes on the servo case bottom cover. These should be located longitudinally along the centre line and 9.5 mm from each end (this applies on the Hitec HS-300 and is also true for many standard servos but depending on your servo type there might be differences). The M4 thread will come out from the servo body using one of these two so this hole must be located directly below the centre of rotation of the servo’s output gear. Be very careful since this alignment is very important! If you don’t get it right you might have to use a new servo! The more accurate you are, the longer your servo will endure. -  Measure the dimensions of the rotating shaft of the potentiometer on the servo’s original electronics – note the geometry in general. The shaft should be flattened right at the tip in order to prevent it from freely-rotating once inserted into the servo’s output gear.   - Take the M4 studding (M4 thread) pick one end and by using the dremmel and the abrasive wheel tool, replicate the tip of the servo’s potentiometer on that end. Start by decreasing the diameter of the thread, rotating it steadily by hand against the abrasive disk (normally to 3.5mm in diameter and at least 6mm in length). Try to think of your fingers as the chuck of a slow-turning lathe. Once the diameter of the thread is down to the pot’s shaft diameter, flatten the tip according to the potentiometer’s tip. The idea is that the thread must be inserted in the servo’s output gear in the same way the potentiometer did before. The better the fit the longer your servo will endure. - On the flat tip of the M4 thread, screw the two M4 nuts approximately 20mm down its length. Following that, insert the two M5 washers. - Insert the thread inside the servo and adjust the distance of the nuts and washers down the thread such that the servo case bottom cover closes properly and the motor rotates efficiently. Basically, you have to make sure that once the thread and the servo are assembled there is no pressure between the servo case bottom cover and the nut-washer assembly. Similarly, you have to make sure that once the thread and the servo are assembled there is no gap between the servo case bottom cover and the nut-washer assembly. Once again, the better the fit the more your linear actuator will endure.   - Once you find the optimum position carefully disassemble the servo, remove the washers from the thread and use a drop of cyanoacrylate on the side of the nut that was in contact with the washers in the assembly. Let the glue to settle for 5 minutes. Unscrew the second nut by 10mm towards the flat end of the thread, and prepare a small epoxy mix.   - Put the mix between the two nuts and screw the second nut back in place. Once in place also use some epoxy on the back of the second nut as well. Ideally you should sand all contacting areas before you apply the epoxy glue. Leave to settle for at least 6 hours (even if you use a 5 min epoxy). - Secure tightly the 4mm diameter brass tube onto a vice by flattening the mounting end and use the M4 tap VERY carefully tapping as deep as possible (at least 15mm). Using the dremmel cut 10mm out of the threaded part of the tube and then verify that the created thread runs along the whole length of the small threaded tube by screwing it onto an M4 screw. Keep the 4mm threaded tube on the screw for handling purposes. Apply a layer of solder on the outside surface. - Take the 5.8mm diameter brass tube pick one end and try to sand at least 5mm into the tube (on the inside). Mount the brass tubing on the vice without squishing it and apply a thin layer of solder on the inside.   - Ignite the flame torch, take the 4mm threaded tube (holding it by the screw) and move it on the soldered end of the 5.8mm diameter brass tube which should still be mounted on the vice. Using the flame torch heat-up both tubes and carefully insert the 4mm threaded tubing inside the 5.8mm tubing until is fully inside. Use a pair of pliers and insert the brass tube by holding the end of the screw that sticks out. Hold the threaded tube levelled inside the 5.8mm tube until the solder settles. If you do not have a flame torch use a candle, your soldering iron and your patience :). Remove the screw. The end result will be the cylinder of your linear actuator. - The cylinder length should be equal to: the actuator’s desired working length (stroke) + length of the 4mm threaded tube which is inside the 5.8mm tube + 10mm for the mounting hinge at the cylinder end.   - The thread length should be: the actuator’s desired working length (stroke) + length of threaded tube which is inside the 5.8mm tube + length of the thread which resides inside the servo casing, which is model-dependant.   - Take the non-threaded/non-soldered side of the cylinder and drill a 2.5mm hole through, 5mm from the tip. - Cover the entire length of the cylinder with heat-shrinking tube and cut-off any excess bits. The 2.5mm through holes made earlier on the non-threaded side of the cylinder are now covered. Use the drill again to expose them and tap them through, using the M3 tap. Screw a 20mm long M3 studding or simply cut-off the head of a 20mm long M3 screw. This will act as your cylinder mounting hinge.   - Take the 4.8mm styrene tubing and M4 tap it 10mm deep. Cut a small ring 5mm in length and screw it in the M4 thread fully, from the side of the nut that was in contact with the washers (long side of the M4 thread). This will act as bushing between the thread and the servo’s case bottom cover. Ideally you should use nylon, copper or metal bushing. - Secure the motor cables inside the servo casing using a glue-gun and use heat-shrinking tube to cover them. Assemble the servo including the thread, the styrene bushing and the washers.   - Screw-on the cylinder and you are good to go! Here is a video of the small actuator lifting 10kg For those of you that have watched my video on the MTR Rover     will understand where the idea of hacking the servo came from ;))   Soon we will be posting assembly instructions, code and schematics on how to modify a standard servo to get full PID speed and position control with 10-bit resolution over 360 degrees – continuous ;)     I look forward for your comments!

Can I run different voltage LEDs off a 9V battery?

I have a small project that uses a 3 light LED list that runs off of 3 AAA (4.5V) batteries, but I also want to power a 12V LED string (for cars about 24" long) and I am uncertain the mA draw for either. This is for a follow-up to fine tune my son's 2014 Halloween costume. I run the 12V string off of 10 LR-44 batteries and get about 3 hours use out of these, so I know the mAh draw is relatively small. I'd like to extend the use of the 24" string. The 3 LED light goes for days on the AAA's.  Because both lights are used for the same application, I wanted to see if I could join them together in a single power source and power off of 1-9V or 2-9V (in serial for a total of 18V) batteries. I think my preference would be the 18V with an in-line resistor, but I do not know which resistor to use. Is this the correct approach? What are other alternatives?

FAA Ruling ends FPV and will destroy RC Model Aircraft industry is USA

Hello, This is a serious matter. Please read and act. Deadline is July 25. Please see this video: Then please go to this website and read  the document "Interpretation of the Special Rule for Model Aircraft".!docketDetail;D=FAA-2014-0396 To summarize, the FAA has deemed that a sweeping, blanket regulation is necessary to take care of an issue created by a few dumb individuals making bad decisions. Because a very, very small few people who never touched a RC model aircraft before buy a DJI Phantom and decide to fly it over crowded city streets crashing into buildings and and almost hurting people, the larger hobby community is now paying the penalty of those dumb people. Why it matters to me: I just got into the hobby and I am not flying FPV yet. Actually I cannot fly FPV until I get my FCC Ham License. I am following the rules. I do NOT fly over people, cars, streets, buildings. I do not fly over private property other than my own. I DO fly within line of site of my aircraft, under 400 ft, in open fields or isolated locations. I do keep my aircraft in good working order. I am an AMA member, have insurance in case of RC accidents, have my AMA number inscribed on my model. So I do everything within regulations. Most RC modelers and AMA members do. But we all pay the price because some bonehead goes to amazon and buys a ready built aircraft and on the first flight takes it to a crowded school playground and crashes it on someone's car. I want to grow into this hobby and advance to FPV. I do it legally, responsibly, and safely. I use this hobby to freely express myself in a safe, harmless way. this hobby is enjoyable, challenging and has forced me to be innovative. I actually invented something that I want to share in instructables one day. Why it should matter to you: The government is slowly eroding away our rights. This regulation criminalizes a hobby that has been enjoyed by generations. Done responsibly, the hobby is safe, enjoyable, promotes innovation and gives people a way to express themselves. It is also an industry that many people rely on to make a living. The FAA as a government agency, is overstepping their authority and threatening our freedom to conduct ourselves are citizens in a safe manner. under this ruling, a RC model operator does something innovative (it does not have to be FPV related) shares it on instructables, and wins a prize from one of the many GREAT contest in intructables... Guess what, that instructables member is NOW a CRIMINAL. You are not allowed to get any compensation for RC Model hobby. under this ruling, you cannot fly FPV in an isolated forest capturing wonderful video and posting that video on the internet as an expression of your creativity. That my friends is Freedom of Expression being undermined. That video is now incriminating evidence that you broke the law. Even though that video harms no one. Under this ruling, an individual who invents a new RC airplane, mass produces it and sells it to others is a criminal because RC models is only for amateur hobby. Any monetary gain is criminal. So it is criminal for someone to innovate and try to make a living from that innovation. Do not let the government overstep their authority over us citizens. I ask that you respectfully tell the FAA to consider reversing their ruling. Ask them to go not take the easy route of making a over-generalized, sweeping, blanket regulation that impacts everyone in the hobby, past, present and future. instead, have them create regulation that target the the unsafe operators who make poor choices. thank you.

Wiring 2 pots together?

Ive mostly seen it in hobby applications. Anyway, I was wondering, am I missing some crucial part or fact that would make this unsuitable for a bicycle power source? thanks.
