Adjustable bed remote fix

I  will have to throw away, at much expense,  and replace a terrific adjustable bed because no one seems to know how to fix the remote control broken red bulb.  After a trip to and from the supposed specialists in WinstonSalem N.C., it came back with NO bulb, and both a screw and a small piece missing!  When I called, he informed me it was working when it left there... How would he know WITHOUT  the bed?  Top that with him insisting it 'doesn't NEED the bulb to work'.   Any advice on what bulb  for a 9 volt, and precisely how to know circuit board terminals ?

Wanted: Electrical Engineer for Tech Startup

Good evening, We are two students who are currently working on our startup project where we are developing a product for the electronics industry. A large amount of research has been made and the theory/concept of our product is in place, but we are of course open to suggestions. As we are in the process of developing our first prototype, we are now actively seeking for an electrical engineer to join our team. As a part of our team, you would become a Co-founder and receive equity in the business entity. We found Instructables and thought that there might be an interest for these type of projects from its members. We are actively seeking a person with an electrical engineering background or similar, who is familiar with the process of prototyping, to join our team. The process of developing a first prototype will include evaluating and matching components, product specifications, product functionality and testing. The goal is a prototype that gives proof of concept with verifiable data that can be used while meeting with investors. Several investors have already been contacted and shown interest, including major angel investors from New York Angels etc.  We do not expect you to know everything, we value commitment and passion over 10+ years of experience and it is important to us that you share our vision and mission. All we require is that you have knowledge within electrical engineering and can bring something to table, especially in the prototyping process. We are located in Honolulu, Hawaii, but are open to working together with you remotely.

How can I multiply/double (or just increase) voltage in a DV 5v curcuit ???

ok i have the following parts to ue for this: (all leftovers from former project..)  :) 1x mosfet IRF510 power transistor 5,6A 100V 9x 2N3904 amplifier transistors 40V 0,2 A .0.625 W ~16x 1uF capacitors 50V ~99x recifier diodes 1A 50V ~35x 2k resistors  0.25 W the idea is to charge a battery pack consisting of 4x 1,2-1,25V = 4,8-5V 3000mah AA nimh batteries using my 5v usb wall charger that has 1A output! i tried connecting the battery pack directly to + and - and 'i think' its starting to charge but after 1-2 hours at full rate (5v 1a) it should be at least 50% charged (3 hours would be full charge -> 5W x 3 = 15W), but if i connect them they last for about 2 -3 minutes and then empty again!! so after this im concerned that i might need at lest 6V-10V to achieve the desired effect !!  -> charge 15W NIMH batterpack with wall charger (nokia ac-60e.. 1-1,5A) i nless than 3 hours (as like a phone would need !!) therefore i need a cuirciut (ONLY DC) to double my 5V OUTPUT to 10V (yiou shouldnt apply more than twice the curent of a batter pack) or ideally 6-7 V but i dont know if thats possible without a swiching IC or more different resistors.. so just doubling would be nice at the moment!!

idea for a simple and thin contact based sensor

Hello instructacles, I'm trying to build a simple contact-based set of sensors embedded in card board, paper or thin plastic sheets. I want to make a simple game for my kids that could detect/react to the presence/absence of some random items positionned on such a board? (empty glass bottle of coke, cereal box, shampoo bootle, you name it) Ideally i would use something like those books for kids where they have metallic threads "printed" on think plastic sheets and when you press them, it triggers a music. But i dont know how to print metal basically. don't really know how to get started. I was thinking of sewing conductive thread but i'm not really sure it would work. I have seen many attempts with aluminium foil (ex: https://www.instructables.com/id/Interactive-Art-With-Scratch-and-Makey-Makey/) but those are based on the fact that a human finger touches them (basically it uses the conductivity of skin), whereas in my game i was to use the weight of random objects from the house (in the 50g to 500g range typically) Any idea how i should get started ? thanks fourchu

A rant about excessive use of acronyms

I am making a personal plea to contributors to Instructables to please, refrain from using acronyms! The same goes for submitted comments. I am not a total novice in computer hardware or programming, but I frequently get caught struggling to understand an instructable or comment because of a needless use of acronyms. Think how someone new to instructables , with little or no background, must feel. I understand that there are times acronyms are used for brevity, but surely a simple explanation of the acronym when first using it would be a help for all readers. In fact a list of acronyms to be used and the meaning of each wouldn't be a bad idea!  The purpose of an instructable (in my opinion) is to pass on a tip, a procedure or even to teach your reader how to do something that you think is worthwhile. An excessive use of acronyms with no explanation/definition strikes me as counterproductive. That makes me feel better, nothing like a good RANT!

What motor should I look into for lifting 50 lbs around 35-40 in. off the ground?

I have a project where I very simply need to raise and lower a flat board with a 50 lbs drill press 35-40 in. and have it stop at the same specific place every time going up and coming down. I've seen TV lift mechanisms and things such as that, but they cost $500 - $1,400. I need this project to cost very little. <$100 if possible. I have a scissor design that I will be made from wood that I already have, so all I need is a motor that can lift 50 lbs up and down, slowly, quietly, and only once or twice a week. But I know nothing about motors.  Here are all the parameters that I can think of.  1.) It will be stationary, i.e. — not require a battery or ever need to be moved.  2.) It must move slowly. Lift the surface approx. 1 in per second. i.e. — around 30 seconds to raise the surface 30 in. or so.  3.) It must be as quiet as is reasonable. It doesn't have to be whisper quiet, but def. not power-drill loud. 4.) It must be as inexpensive as possible.  I do not care about... 1.) Motor weight 2.) Dimensions 3.) Power consumption 4.) Heat production 5.) Longevity... it will be used very rarely so wear & tear is a non-issue really I very much appreciate any help you guys can give.

Safety of your garage door or car remote...

No time and no pics for a proper Instructable, so I just put out some word of warning ;) Around here bad people take advantage of the fact that a lot of new houses have the garage right next to the house. With these you usually also get a door so when you park your car you don't have to get out of the garage again. All controlled by the press of a button on the remote... Some fancy guys got a device working similar to the IM-ME Open Sesame hack a few years back. But unlike the original author the new guys found ways to make money by providing working "universal garage door openers" on dubious websites. Problem with the new model is that it not only fakes a remote with dip switches but also the newer models with so called "rolling code", "intellicode", "changing code" and so on. The old remotes with dip switches should actually by phased out years ago by any owner who values his stuff... But the new models are still deemed secure and next to impossible to hack - well if you trust the advertisement... How does the code hacking work? The old dip switch models allow for a maximum of just over 4000 different codes and come in just 3 or 4 frequency bands. No real problem for anyone with basic electronic and coding skills to hack these - as shown with Open Sesame. The new models all use a so called rolling code, here the remote and opener are paired through 32 bit of ID code and an encrypted part that changes every time. Both remote and opener calculate the next code once a button was pressed or a code received. To overcome reception problems the base usually calculates the next 256 codes in advance - and that is the entry point for bad boys. The illegal device scrambles the frequency detected while storing the code received by the orignal remote. As the door did not open the owner will try to press the button again. Still scrambled to opener does nothing - until the device sends out the first recorded code! Now the owner can drive in and is happy. Of course he still needs to close the garage - again all is scrambled and the code stored as before. You see where this is going.... It is even possible to set the amount of required tries to capture, so in theory a bad guy could get the next 10 or codes in advance for use once the owner is gone out... Worst thing however is that these illegal devices not only open garage doors but also cars as a lot of them use similar systems for their remotes - up to the point of starting the car with it. Took me only 2 hours with Google translate to find a website outside the usual search results that offers these "gadgets", along with WiFi and cell phone jammers, credit card copy devices and more things I don't want know about... What can you do to protect yourself? First check what type of remote your system uses - if there are DIP Switches than replace the remote system or the entire device in favour for something more secure. If you already have a rolling code model that you are far better off but sadly no longer totally safe here. A lost remote should not only be replaced but the old one removed from the system as well - you never know if you just lost it or someone took your remote ;) Alternatives exist, especially if you are not afraid of doing some open heart surgery on the electronics of a garage door opener. You can add a WiFi module and use your mobile phone to open the garage - search Google if you like the idea ;) Another very neat way is using a second transmitter that keeps the relay for activating the opener from working. This can be anything from a BT module paired with your phone or cars BT system over a keycard to numberplate recognition cams. A good system also allows for a "holiday mode" or similar. Here you can set this mode with one remote until you deactivate it with the same remote the system will not react to anything. Great if you leave the house for more than a day or two... As a last resort you can always get a big and angry dog to sleep in your garage.... What if you are renting or a bit limited with the electronics and soldering skills? Not all is lost if you can accept a second remote for added safety. These days you can get plug in converters for your mains voltage outlets that work with a remote control. Unless they use Infra Red for this they are great to disable your opener. Simply plug it in where the power cord for the opener is and then plug the cord into it as well ;) Now you can fully shut off the opener with the press of a button and only if the power outlet is switched on the opener will work. If in doubt you can use a double outlet adapter an extension cord and a night light to indicate wether or not the opener has power. Ok, and what about the door lading from the garage into the house? Well, of course keep it locked and if you are home also keep it locked. At least this way you have some extra time in case someone tries to enter through your garage while you are sleeping ;)

I am willing to PayPal $30 for someone to write this Sketch.

I am willing to PayPal $30 for someone to write this Sketch. I have an Uno board, a motor control board L293D Motor Drive Shield and a 5 volt 4 wire motor NEMA17 Stepper Motor. I'm using #include . I can make the motor run any speed in both directions in a loop. That's all the further I've got in two weeks. I would like it to start idle (hold) and when I touch (momentarily) power to a pin, I need it to run in reverse until another pin is contacted, a switch, and stop (or run forward a small amount). Let's call that home. Then I would like to touch power to a different pin and have it reverse to home and then run forward 200 steppes. 3 more like that, 200 steps, 400 steppes, 600 and 700 steppes. So, i need 4 pins, one the run the motor to home. The 3 others will run the motor down to home and the up to a predetermined spot. The "Stop and stay home" can be a couple steppes up from the home switch. Think of it as running blinds full open & closed with 3 available open positions in between. If you can do that, I'll pay $30. But I don't want 10 people to make it and each expect to get payed. How do we do this? Scott Goldsborough Thank you!

Circuit Diagram for LED bulb running on 120V AC

I have been watching a lot of YouTube videos of building your own LED bulb using a scrap CFL bulb. Since I have watched a lot of those videos, I want to build one. However, almost all of those videos are about making one that runs on 240V AC, and where I live I use 120V AC. Take this video for an example: I also noticed that in that circuit diagram, there is a 5th diode that is unnecessary. So I want to build an LED bulb similar to that one in the video above. But I am not so good with electricity, so I am not so sure how I can modify the circuit so that it will run with 120V AC instead of 240V. Can someone help me with this?

The following I'ble is a good example as it contains a few "I made it" comments: instructables.com/id/Enchanted-Rose-Beauty-and-the-Beast UPDATE: This issue now appears to have been resolved, everything is behaving as expected.

I accidentally invented a device to collimate any light source into a concentrated beam... what should I do with it?

I've been umming and ahhing about what to do with this for the couple of weeks since I accidentally invented the thing (I was working on a solar energy device), and I thought you guys may be your usual well-spring of help and advice. Basically I seem to have designed a device which will collimate an extended light source. Any light source. So you could, for example, turn a 100 Watt light bulb into a 100 Watt laser. Or a square meter of sunlight into a kiloWatt. I haven't made it, but simming on the computer gives an optimal blow out rate of about 1/2 meters per kilometer, so over a range of meters or tens of meters it's pretty much as accurate as a normal laser. The only upper limit I can see on how much power you could put through this thing is when the materials start melting, which would probably be pretty high. There's really nothing fancy about it, it's just a shape. You could print it out easily on a 3d printer and fill it with some kind of settable glass for the total-internal-reflection. It would weigh about as much as a 2 litre bottle of water and be about the same size. I was concerned about it being weaponisable, but even at a kiloWatt the lethal range would probably be less than 100 meters, in which case you might as well just get a gun. I don't know if anyone's already done something like this, I can't find anything online, and people kept telling me it was supposed to be impossible. So, um, yeah...

What is Collection in Instructables?

After reading some explanations about Collections, I still don't get. Could anyone please explain what is Collection in instructable, and what is used for? Why I can edit the collections, which are someone's published instructables? Is there any official guide about how to use Collection? Thanks.

Old Engineering Exercise

Hello all! I was just looking through various Maker projects, here and elsewhere, and was reminded of a collage engineering exercise I was told about growing up.  Apparently, they don't do it any more.  My education is only up to an Associates Degree in Drafting and Design, and I never got this at that level. This exercise (near as I can remember) consisted of a student being given a piece of aluminum (I think) and a set of files, a caliper, and a few other small tools.  The student then had to turn the piece of aluminum into as near a perfect cube as they could, using only those tools. Has anyone out there heard of this exercise before?  Maybe done it themselfs? Namely wanted to through this out there, see what people thought.

I originally posted about converting a John Deere Power Wheels tractor to remote control powered through the RPi. I decided not to for various reasons. Time was one of those reasons. Now, I have been able to come up with a large scale electric remote control vehicle. I'm looking to hook that up in a collaboration with the Raspberry Pi. I have some ideas but just wanted to get some opinions and maybe even a difficulty rate as for as programming and so forth. Any help will be much appreciated!
