SImple heads up display circuit? Answered

Hi, i am a sophomore in a small town in eastern Oregon. I need help, a lot of it, in building (from scraps or anything found) the simplest circuit possible to connect a non-webcam camera to an lcd screen from an old cell phone. I have little experience and i know i shouldnt start with this, but dont give me crap for it. I can learn to do things easily but need to build two circuits like this for a helmet i am building. If you people could get me direct help or if there is an engineer floating around i need help. I am planning on becoming an electrical engineer and want to start here. Please either help or point me through the right doors. Thanks. P.S. my budget is kinda low but i can pull it through and ask favors.

You got brains in your head

Ever wonder how your brain sits in your head? How it would look sliced up or from different perspectives. MRI currently allows you to do that, but these crazy Sweedish/Hungarian let everyone interact with brains, not just doctors. Using MRI data and some headtracking they made some interesting visualizations check it out:Brain Mirror

Old Smartphone LCD as Head Mounted Display?

I've got an old HTC EVO 4G, otherwise known as the PC36100.  I'm attempting to create a 1 to 1 display to connect directly to my computer for a cheap Head Mounted Disply.  I've attempted to use various wireless RDPs.  However, the lag while attempting to do ANYTHING is horrible.  So I attempted to find an app that would connect directly to the phone via USB.  I found two.  Neither of which I feel comfortable dropping money on with such poor reviews and trials that don't work. So finally, I decided why not just use the LCD directly.  No messing with the hardware limitations of the phone at all.  So I took the phone apart.  I got right down to the LCD itself and found that it has a 17-pin input.  But, I don't really know much about it beyond that.  I can tell you that the cable reads: Career 06 94V-0 <->2 C36_FPC REV A I even have a picture of it.  I think it's attached.  If not, I'll fix that. Essentially what I want to know is, what do I need to make it be a fully working LCD monitor for my computer.  I know I'll need a module to convert the signal from what it is now to HDMI or VGA whatever the case may be.  I also know I need power to the screen.  But, beyond that, I don't know where to look.  I've tried looking up the cable information, but I'm not getting great results.  Any help in the matter, would be greatly appreciated.  Thank you.

1 Console 4 displays

So here's the problem, my friends and I are in college and love our x-box console, but hate the small screen. Not having a big scren, we are trying to find out how to get the one console to have four screens. We all have smaller TV's and there is on medium one in our living room. The game splits up 4 players into equal quaters of the screen. My thought is that the x-box video should go into a laptop and then be split u into 4 displays, with the laptop screen being the a full screen. The laptop in question has 1 S-video, 1 standard monitor output, and 5 USB ports. How do we do this, for cheap? I'm thinking it would maybe work like those walls of TV's that make up 1 big picture.

Wiimote Head Tracking -- Nintendo: Please do this!

Johnny Lee did it again! Head tracking with the Wiimote!From his blog:"Using the infrared camera in the Wii remote and a head mounted sensor bar (two IR LEDs), you can accurately track the location of your head and render view dependent images on the screen. This effectively transforms your display into a portal to a virtual environment. The display properly reacts to head and body movement as if it were a real window creating a realistic illusion of depth and space. "I really hope Nintendo looks into this -- even though it only works for 1 person. After all, most games are 1-player, and those games are the ones that would best use this feature.If I had a bluetooth adaptor, I'd play around with this some, but, alas, I do not. However, this and his other projects would work the same with a video camera that has an IR filter.Funny, Sony really didn't take enough advantage of thier EyeToy, if it was IR-only, they would have been able to do more...

In over my head - pH automation

Hi all,I'm in need of help. Due to my previous jobs and general knowledge a friend has asked me if I could build an automatic pH regulation system that will monitor and maintain two tanks (it sounded easy to me at the time) but I've suddenly found myself out of my depth.Having spent long evenings searching on the web and on here, I've seen a few builds of monitors and a couple of dosing systems but none are just what is wanted as they are only set up for single tanks, or not combined into an auto-doser, or too "over-tech'd" or multi-purpose orientated and I don't have the knowledge to adapt or alter things to my requirements. Plunging straight in at the deep end with no real idea of what I'm doing and can actually be done, I'm thinking I should be able to (theoretically) assemble and program an Arduino controlled system, with the one box doing the job of monitoring and regulating both tanks independently, so two sensors, pumps etc., from what I gather it's by adding different boards to the base unit (I did say I know nothing). I don't need wifi or anything like that, just a simple device with a basic display showing the current values that will sit there and just do the job.I think I have the capability to actually build and program the thing having a background in electrics and a little knowledge of relay control systems - not electronics, I start getting lost just after the transistor/diode level and BASIC is more my programming level (yes, I may be THAT old, but I'm still trying to learn), and so what would really help me is if anyone out there can point me towards a site or pages where I can find the info I need, hopefully that doesn't assume years of prior experience, to either build or adapt something to what I want, or even aim me towards someone who could be able to supply me a design and components list, either for fee or free. Cheers!

Traveling horizontal lines on a projector display?

I hooked up this projector at work (it's a BenQ) and when I view the projected image (in this case a computer screen) I see horizontal lines traveling up the picture. This projector is the only thing on the circuit right now.  I had to branch off the existing electrical line to add a new plug on the ceiling.  When I plug the projector into the existing outlets I get no lines, when I plug it into the outlet I installed I get lines.  The existing outlets on the circuit are all isolated grounds.  I have tried wiring in a regular outlet and then switched it to an isolated ground when the lines appeared, thinking it could be a ground issue.  I know my wiring is correct as I've installed these projectors before. What could it be?

Can i run a Rasberry Pi and a 10" Display from the same Battery? Answered

Hi, im planning on creating a portable Rasberry Pi Desktop. I found a bunch of circuit plans to run a RPI and a 10" Display - however iam not statisfied with what people came up with. 1. Issue - in the circuits i found they connected a booster to a 3,7v Lipo Battery to run a 5V Rasberry Pi and a second booster and the same battery to run the Display. This is a pretty incomplicated but impractical design if you ask me - the benefit here is that the boosters allow you to charge both batterys whilst the devices are running - but you need to connect 2 different cables. I would like to be able to charge the System with only a single power cable (Micro USB) attached. 2. Issue - The 10" Display does run on 5V, 980mA - but it is not reccomdendet to use it under 6V, 780mA - as a person who likes staying on the safe side - i would like to run it on 6v. Can anyone come up with a concept so i can run both the Rasberry Pi and the Display on the same Battery and charge the Battery whilst the devices are running? I thought about using a 6v Lipo Battery pack - but i need something to lower the voltage to supply the Pi correctly. Is that a good idea? Can you reccomend some other solution? PS - Is there also a way to monitor the remaining Charge in the Battery?

How to view the view of a SQ8 camera on your computer?

So I got this SQ8 camera just for fun. Right now I'm wondering if I can show the the camera's view on my laptop? The SQ8 say it can connect to TV and show it's view, can I do the same with my laptop? Here is what I conclude: The USB port of the SQ8 provides 8 wires. However, the cable is split into 2 wire, 1 to the USB head (which have 4 wires) and 1 to the plug for the TV (by the look of things, there is only 2). I have no idea how data is transferred, but here is my guess. The USB head will provide power for the camera to charge and the last 2 wire may have to do something with shutting the connection (If I press the on/off button on the camera, my laptop signal the device has disconnected/reconnected to my laptop).  The 2 wire that transfer the image to the TV is the yellow head, which I have 0 clue how it works cause I haven't learn about it. My question is: is it possible to take this 2 wire to connect and display my camera's view? Here are pictures that I took. In the pics there is the port that the camera has and the 2 end of the cable.

Hi all. I am having trouble finding how to preset the minimum output of a 4029. Meaning that I want it to start at an output of 5 (0101) and count up to 15 (1111) and then have it start counting at 5 again. My project is an ASCII counter to check that the ASCII displays with 7 bit binary inputs that I have are functioning correctly and I want to use the 4029 as my input. The problem that I am having is possably misinterpreting the data sheets but is seems that in order to preset the input, the preset pin has to be HI but to run, it has to be LO. Does this mean that I have to set the prest HI, input my preset value of 5, and then bring it LO again to run?   Any help would be appreciated. Thank you much in advance.

Setting up two forges...

Basically I have two ideas, one of which I'm pretty ready to make now and another which will take a little longer to make, one is a tiny forge, like desktop sized, for working at home and the other is a much larger forge for big metalwork projects, thankfully the large one will actually require less parts scavenging as I have plenty of acces to scrap material and there's a brickyard over the wall from us which will do me the necessary materials very cheap, mainly because I did a little forklift driving for them for larger heavyweight loads over three tonnes. That's all well and good a big one I can get my head round easily enough, But. How would I go about making a tiny forge and I mean miniscule, it's main purpose is for heating to cast for my specialist parts I prefer making and the other is for low material single cast jewellry my mum makes (she used to own a jewewllry business and still makes the odd bespoke items. But my main question is how I can build a reliable yet compact forge and furnace, from what I have sitting around I'm sure I can come up with a decent fuel source, ranging from butane torches and stoves, both of which can do propane and I could go to natural gas (we have a special plug out the back for gas barbeques the house had it when we came...) but my other questions are a bit more odd, first of all what would make a great crucible, I need something that'll be fairly invincible to the hardships caused by life, as the other liely user of the forge and furnace is very forgetful and sometimes accident prone. Next up is the housing, would it be feasible to use a single block of thermocrete cast to make the main furnace housing, as in everything is but the fuel and air source holes and the crucible hole would be one block, as it stands that seems like the best way to make it simple and effective, plus it would be pretty airtight where needed. Next question is the fuel and temperatures, I know that butane at full combustion get 1300C and 1000C is a practicable operating temp. for a butane item but what about propane or even natural gas, since it would be very cheap and clean burning... I'm a bit of a noob towards this end of the scale, I can make stuff hot and I can do alot with these things but actual forge and furnace making is a little beyond me on this scale, however I can think of several advantages to my baby furnace, including the practical movement of it, as it could be self contained very easily. The pic was just one of the last pictures that's remotely intersting I uploaded, however it raises it's own points as the jet engine basically welded all it's components forward of the flame together.

Suggested Project/Instructable: Holo Display

Hello all, I had an idea a moment ago for a "holographic" display but I realise that I do not currently have the supplies necessary to complete it. It is actually a combination of a couple other peoples ideas to form a new concept. Someone on here, (open new tab>search) NK5, made an instructable on how to make a kind of hologram. Another cool frood, Johny Chung Lee, came up with and did some basic programming for a different kind of simulated hologram and a multitouch system. And lastly there was a group that made a pair of specialised LED gloves to go with the multitouch system. My thought was: make a reflection hologram and use the Wiimote multitouch system to make it interactive. Project the screen onto the floor or put a large screen tv on the floor (if you want to risk it. and place the glass over it at 45 like with NK5's idea. Put the wiimote at the base of the glass. (it would be simpler if it were behind the glass but I think glass disables IR cameras) Then put on the IR gloves and run it all together with a program that supports the multitouch. Once you got the hang of it it would be more or less a "Minority Report" type display. Well, that's it. I can't make this because I do not have a projector or a pane of glass anywhere near large enough. Nor do I have sufficient expandable cash to purchase such objects. Good luck.

I want to share more information about the build, and also get peoples ideas and opinions so lets see what people come up with! I am also happy to answer any questions about how it works, or what I am planning on doing with it. Currently in the works: I have a friend who is "flash savvy" helping me make the HUD interface. We will be streaming the feed from the webcam as the bottom layer of a flash file. We can then overlay well animated and styled objects over top of the feed. This allows the user to access whatever applications they find useful without having to change perspectives. The camera that I am waiting on has a far higher resolution that the screens are capable of outputting, so by selecting areas of the screen to "zoom in on" (expanding the selected area to fit the screen) you essentially have digital zoom. I will upload sketches of the adjustable screen mounts soon. ... and remember kids, the future is now! (for real! look around you)

Rotating Powered Display for GEEK swag

OK, Ill admit it, I'm a nerd.  I'm a Star Wars fan, and I got a new den that I want to geek out. I have a museum-quality X-wing fighter that I want to display on a counter top (&&&).  The piece has a display base, and a acrylic post that the model sits on - and through which three wires go up into the model and illuminates the outer engines, and numerous cockpit fiber-optic display bits.  It is uber-cool to look at in the dark. 8-) But I want to fab a custom display base that ROTATES so the model does a slow 360 revolution over, say, a minute or so.  But I also want to KEEP the lights. So, my puzzle is this.. How can I fab POWER RINGS, so that my model can display its lights as it revolves? -Or- Is there any way I can hack some kind of cheapo commercial wireless power conduction thing, so that I dont really NEED hard wires at all.  I can rig some rechargeable battery pack onto the rotating display base, and something that transmits the power on the table-top base (that doesnt rotate).  To be clear, the motor that does the rotation OF the base I can wire directly to the wall, But for the LEDs built into the model, I figure I need maybe 40mW of DC power that I want transferred to the batteries on the top to juice the model while turned on. I get this idea from my Wii wireless controller recharger.  I only have to put the controllers onto a special plate plugged in to the wall when not being used, and they recharge.  With this, SOMEHOW, power is getting to the batteries in the charger *without* being directly wired to the charging adapter. Anyway, since everyone on this site is a genius, I know the can give me an idea or two. HELP ME GET MY GEEK ON. -Dave &&& If you're interested, it's the eFX Collectibles RED FIVE X-Wing Studio Scale model,

Interfacing with an LCD display from a Canon multifunction printer?

I recently salveged an LCD display module from a smashed Canon all-in-one printer.  So far, I have been unable to search up any information on it.  The manufacturer seems to be "APEX" (see fifth picture), and the circuit board has a backwards "RU" mark.  Any ideas as to how to talk to it, possibly with an Arduino? If, as I suspect, the module is an OEM part, and datasheets are not available, do you have any recommendations as to how I could try to experimentally determine what the contacts do?  (I got it for free, so It's not too critical if I destroy it...) Thanks! - Infinitevortex

My last instructable is not showing up in recent section

Yesterday, I posted a instructable in Technology section under Arduino channel. The public link works, but it is not showing up in recent as well as in search results. Here is the link - https://www.instructables.com/id/DIY-Digital-Clock-With-7-Segment-LED-Display/. Can anyone address this problem and suggest what I did wrong there? This never happened before to me.

IS there a way to hack a Laptop LCD to work on a Desktop??

I bought a couple of broken HP laptops in hopes of making one good one well it hasn't turned out that way but I was thinking that there must be a way to take one of the LCD displays and hacking it so I could use it as a second display off of my desk top if this could be done then i will go look for a older over head display the drop the laptop display into it https://www.instructables.com/id/LCD-Overhead-Projector/ and try that
