So here's the deal, I am totally stuck. I've been looking all over and can't find what i need. my church has 3 projectors for one stage, two on the sides and one in the center, we are planning on buying a couple rgb panels and playing some video loops on them, what I need to happen is for a vga or dmi signal to go to the arduino then convert to rgb and then to dmx to control the panel's. I have little experience in arduino programming so any help would be great.

Alright so, I've recently aquired a keyboard from a desktop computer made in 1983 and I fell in lovewith it at my first sight of it. However I am a lot younger than this keyboard so I know nothing about it so I was wondering if any of you could give me any background info on this keybaord and and any thoughts on whether it would be possible for me to convert it so i could plug it into my slightly outdated desktop computer and how i would go about doing so. Pictures below.

Hey, I was just wondering, could we turn a turbocharger into a generator that would produce electricity as water flows into one gate and out the other? Similar to a hydroelectric generator using the mechanical energy of flowing water through a turbine to produce electricity.

Ok so long story short i want to make a serious home theater system. i have all the amps and speakers, but they are from a car. so i will need to run them from 12ish volts from my home outlets. so i cam wondering what kind of adaptor i should be making or using. i see pre-made ones that have an output of 12v with their amps ranging from 3-15 and watts from 3 to 300. i am no electrician and have little electrical experience, so i am wondering if i should go with more or less amps and watts, i dont need to fry anything as the amp and speakers i have are expensive! THANKS!

Question by purbasha | last reply
I have a Dell computer ATX power supply which I want to convert to a hobby power supply providing +12volts and +5volts. The Dell power supply does not have a switch which I do not require anyways. 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?

I'm looking for an AC to DC power converter. It needs to be 110V input and i need at least 30 Amps of output. Output voltage is not as crucial but at least 50V would be ideal. I need either a product i can purchase or instructions on how to build. Im not an electrical guru by any means so purchasing a product would be better. I am aware that this is going to be costly. It does not have to look nice. I will be wiring it directly into a unit and will have my own casing. Can anyone help?
Question by aeudy | last reply
I currently have bought an aquarium pump from the UK and am using it in the United States. I have bought a step up transformer that goes from 110v input to 220v output. The pump works, but is not functioning properly, it loses flow rate over time and gets pretty warm. One thing that I think may be affecting the performance is that the frequency difference between what the pump is rated at and what is supplied here in the US. What would be a cheap (<$100) easy way to test if it is the frequency issue? How would I convert it? Thanks!

Hello, It happens to have a wireless mini keyboard with touchpad, like the one in the photo ( not this model, but something like this). The problem is that I did a terible mistake and I bent it a litle (some milimeters) and after that it keeps sending repeated characters. I do no think I can fix it. I like to convert and keep alive old things so I had the idea to use the RF modules of the keyboard and make an old PS2 or USB keybord wireless. Do you think that there may be a chance I could do it? Hope you will come with some ideas

Ever since i saw the 'ible on converting a land camera to take 35 mm film, I figured there had to be a way to take this even further. I'm even thinking the first baby step shouldn't be too hard- simply mounting a digital camera to the frame. Now, it would be a little more complex than this- taking the lcd screen off of the base, and putting it on the back of the camera, mounting the actual machinery of the camera where the original lens was, and perhaps even mounting buttons (or on some digital cameras, the wheels for 'scene selection' on the base of the land camera. The only problem I can find with this simple conversion is the fact that it seems most digital cameras use micro ribbons now, which would be (as far as I can tell) incredibly hard to splice and extend (which would be necessary to get the lcd screen, and other components mounted on the frame of the land camera). Does anyone have any ideas for this, or are is my goal too lofty? THanks.

I know this is a long passed DIY. But while building a ATX Power supply I separated all the wires as stated. I then put the green and a black wire to a switch and added the 3 brown leads to the orange leads. When I plug in the unit the supply light comes on, but when I turn the green wire switch the main power LED goes out and no fan comes on. It acts like the switch is shutting the unit off. Can anyone help. I am 60 years old and just getting into doing some bench work to pass the time. Thanks for any help.

Hi Again, My question is when building an ATX power supply, Can you join the 12 volt leads with the 5 volts leads to make 17 volts? If not how can I get lets say 20 volts. I am going to use a DC to DC converter to make a variable power supply. I would like at least 20V in then I can adjust from 1.2 to 60 volts out. I use it now running directly off battery but would like to add it to the ATX build case. Thanks for any help again.

I didn't make this into an Instructable because my wife is visiting Minnesota and took the digital camera with her. If anyone wants to build this and photograph their process, just include me as a collaborator and I'll be happy... :) I just acquired a new (used) video card for my Mac. Unfortunately, it has a ADC (Apple Display Connector) and a DVI (Digital Video Interface). While the card is capable of driving two displays, I only had a DVI-VGA adapter and ADC-VGA adapters run $50-100US! I decided that I'd just have to figure out how to wire my own adapter and run it to an unused PCI plate. The following schematic is a DVI-VGA adapter. I've included the pins that would be used for the equivalent points on an ADC connector. I just finished wiring an ADC connector to a VGA connector on another plate. It works perfectly! I hope this saves someone else a few bucks... Vegas

Hello there! I am building a custom digital weighing scale. My issue is not about how to do A2D, but on how to use the least amount of power doing so. So imagine you just placed an object on the scale, i want the microcontroller to notice a change in weight and perform a2d on the load cell voltage. Now i only want to perform this a2d once(or a few times to make sure it works), saving the value in the register, and then i want the microcontroller to go back to sleep. The microcontroller will keep sleeping unless the object is removed or the weight changed, where the A2D works again for a couple of times, notes the value, and then sleeps again. So my question is, does the A2D have to keep working to notice a change in the weight? or can that happen some other way? I basically want to make my battery last a long time, and i want to do that by using the A2D only when needed. On another note, does a2d even use up alot of power? If i keep it running would it consume alot of my battery? If things are unclear please ask. I'm afraid i didn't articulate well. Thanks!

Hi everybody. I have a quick question I would like to throw out there and hope somebody can help. I am in the early stages of making an autonomous robot and one of the functions I would like it to have is the ability to hold a conversation with people. I have made a previous cardboard robot as a proof of concept for my next build and used an iPhone chatbot app which worked quite well, but I would like to make my own stand alone chatbot. I am aware of the likes of "Pandorabot" and "Cleverbot" ect, but what I would love to do is program my own stand alone chatbot using the available hard drive memory on an old laptop I have laying around collecting dust, and use the Windows xp voice recognition to talk to it (speech to text) and have it respond with a spoken voice (text to speech) which would come out of a Bluetooth speaker located in the robot. I know my way around a computer to some degree but do not know how to program (although I did follow a program written down once to make an analogue clock many moons ago), but with some hopefully straight forward instructions I am willing to learn and give it a go. I have a rough understanding what AIML is but don't know what I would need to use it. I want to go down this road as I want to have it off line, i.e not have to rely on an internet connection, except maybe my home network to connect to another device, not to rely on a second party server, and would like to put the old laptop to some use. I know I bit about teaching or training a bot to respond, i.e, giving multiple phrases or questions with one meaning (eg Hello, Hi, What's up, Hi there ect,) and the bot to recognise and respond accordingly, and I'm aware it will be time consuming, but it's the basics, or starting blocks that I'm after, getting a bot up and running and ready to be taught or trained, and if it's something I can get my head around and it's something I could realistically do, I would love to give it a crack. So, Is it reasonably possible for me to use my old laptop for the sole purpose to use it as a chatbot, what would I need to set this up, Can what I need to know, be broken down in to easy to follow steps for me or anyone to follow who does not have experience in this field, And what recourses are there that I could use if needed? Any help, thoughts and suggestions that anyone can offer to get me started on this idea really would be greatly appreciated, and may be of help to others too as I have not seen this sort of question asked anywhere on the inter web in regards to just using a home computer / laptop. The only information I can seem to find relates to online bots. So thank you in advance for any help offered and I look forward to any responses. Steve.

My girlfriend has had a few requests to have the photos she takes (Currently edits everything herself and sends to users via dropbox) in a cd format. Now, she claims that the file sizes are too large for a cd to hold, but there has to be a way to do this. I was thinking loading everything onto a SD card or putting a few images onto 1 cd. Is there any software that would hold approximately 10-25 pictures and not be a lesser quality product than what she is currently doing? (She really needs the product she hands over to be good-great quality, she only takes customers via referals.) She has professional camera equipment, a samsung galaxy s 5 and a laptop to edit.

I have an 19" LCD monitor that the backlight finally went out on. I'm assuming it's the ccfl since they starting flickering and changing colors months ago but now they are dead. I opened it up and it use (4) 16.1 ccfl tubes. I was thinking of maybe converting it to use LEDs. The thing is that I don't want to use a separate power supply. I'm figuring I will probably need about 40 or more LEDs. How do I find the power I need from the monitor to power 40 or more LEDs? Has anyone had any experience with this sort of thing?

I need to create a 90 Volt DC Power Supply using a capacity, toroid and bridge rectifier. I know that with a toroid you have a primary (input) voltage and then you'll conserve power but have a different secondary (output) voltage. I know that if you put say 120 VAC in the primary, the outputs might be, for example, 50 Volts out, which are also AC. I want the voltage to be DC, so I know that I need a bridge rectifier that will boost the voltage by 1.41 because of the AC to DC conversion. However, you also need a big fat capacitor, and I have no idea how to size and select this. Help?
