Raspberry pi and MHL

Can you control a raspberry pi through MHL. My aftermarket radio supports MHL to control android phones and display the screen as well all from the USB and the cable. So, I was wondering if the raspberry pi could be controlled the same way. I've though of installing a USB touch screen overlay on top of the radio to control the raspberry pi that way and provide video with rca converters or just the rca 3.5 jack on the raspberry pi. Any clues or advice?

Using an old laptop's display with Raspberry Pi?

I'm making something using the raspberry pi and I needed a small display.  So, I took the screen out of an old, broken 11" laptop, but the screen still works.  But I cant just plug the screen into the pi because there are different wires needed.  The laptop screen was connected with a video lcd cable and to connect to the pi you need hdmi, a video wire, or if possible a usb connection.  So is there such a cable that could convert a lcd video cable to either hdmi or just a video input? I searched for one but found nothing.  Thanks

PS1 LCD Screen into a Raspberry Pi Monitor

So i finally purchased a Model B Raspberry Pi. I'm quite enthralled by the stuff ill be able to do with it, but i figured i would start by making it a case. That idea somehow resulted in using a cigar box i had lying around to turn the whole thing into a laptop-esque build thing. The inside dimensions being 8.5" x 5.4" x 1.5", i looked around and i have a PlayStation 1 with an LCD screen. The console and screen are fine but the hinge is broken. And given the size of the screen, i thought it would be really nifty to disconnect the screen and use it as a monitor. The only problem is im not sure if i could make it HDMI or RCA compatible. Any Tech people think this could be done?

Raspberry pi Portable: One battery for screen and rasp? How?

I'm trying to make a Portable Raspberry with an old laptop screen. My doubt is if I should rearrange the battery to deliver ~5V to the raspberry and use a boost converter (XL6009E1) to deliver ~9V to the LCD driver, or if I should make the battery pack deliver between 9 and 12V, and power the LCD driver directly, and use the boost converter to step down the voltage to the raspberry. Thanks Guys ;)

How to use ipod screen as raspberry pi monitor?

I have several ipods that more or less seem to have puked on me; i have one-5gen Ipod Video, one Ipod classic and one 16gb gen2 Ipod Touch.  The two former ipods have failed hdd's, but the screens should still theoretically work. The ipod touch is more or less fully functional, minus the speaker/headphone jack. It is also jailbroken.  I wanted to make a super small portable gaming setup with my raspberry pi, and im wondering how (if it is possible) i might be able to salvage one of my ipod screens to use as the display. Does anyone know how? Also, seeing as the raspberry pi has the hdmi output, how would i go about incorporating speakers into the unit as well?

Good TINY colour lcd/screen for RPI? +What LCD is this?

(My LCD in comments) In need of a  tiny screen for my raspberry pi, the best one I have seen is 1.44"  https://www.adafruit.com/products/2088 But I am actually looking for something smaller and as high quality as possible while keeping my budget under the £25 mark. Optimum size would be 15 by 25mm but obviously that is impossibly as this for the main display. To be used as a computer right next to your eye; (I am using focusing lenses) (Raspberry pi) Brilliant is around 15 by 25 Good is 20 by 35 Kinda bad is 3.5 by 3.5 Preferably detached from board (wires-  unlikely) and rectangular ratio. Must be Raspberry Pi Compatible. UK please! You guys here, are incredible that you can answer me and my persistent waffling and stupid questions for free, so thanks so much. Regards Rowan

IR source detection on a screen?

Hello everyone, I'm trying to find a way to detect a IR source -a LED- from 100m. I only need to detect the source, I do not need to transmit data.  When I turn the camera towards a IR source the software would put an icon on the source BUT without seeing the beam. Namely, the led should look like it is off but the icon on the image should indicate that it is a IR source when it is on. Thank you all!

Reading Electric Meter with Raspberry Pi

We have a meter outside of a building which displays how much energy the building produces (Solar Power) and pumps back onto the grid, how much the building uses from the grid, and the difference. Every day we record these numbers, and enter them into an excel spreadsheet, so we know exactly what the efficiency is of said building. The issue is, is that this building is empty for most of the week, and driving to and from the building costs time and money. So, the idea is that we have a Raspberry Pi connected to a camera photograph these numbers, and send them to us via email. How would you have the Pi take pictures? Specifically, what camera would you use? The screen is a ~3cm x 12cm LCD display (Similar to an alarm clock display, no colors) The clearance inside the box is about 10-15cm from the screen. The box itself is transparent, but we'd like to keep the camera inside the box, as the plastic isn't 100% clear (weathering), and it would also look more professional.  The box is waterproof, but not moisture proof, so it would need to be outdoor rated. Or is there some type of device we can put over the screen, and then have it copy what the screen displays? The screen/meter itself cannot be tampered with, as it belongs to the electric company.  This camera/device needs to be able to be sourced in Europe, and would be nice if it wasn't too expensive. Semi off topic: Would it be possible for the Pi to somehow analyse the images, and convert the numbers in the pictures to text?  Taking it one step further, would it be possible to have it automatically enter these numbers into a spreadsheet? This display cycles through about 10 different "screens", of which only 3 are needed. Could the camera be used as a motion detector, and when the numbers change, it takes a picture? This would be repeated 10 times, so that every screen would be captured, and then the needed images would then be sorted out, manually or automatically. If any more information is needed, just ask. Thanks!

Raspberry pi 2 processing capability?

Hearing the announcement of the new latest and greatest Raspberry Pi 2, now a backwards compatible computer with a 0.9GHz ARM Cortex-A7 quad core processor and 1GB of LPDDR2 SDRAM, I was wondering of the feasibility of using it as a very cheap and basic solution for a simple computer for my lab. Currently, I am using a compaq presario C700 Pentium Dual-Core laptop, that has been maxed out with 2GB 800MHz kingston RAM, and is running Kubuntu. I should also not the HDD has been replaced with a 120GB one from an old and broken Xbox. I do not like it much anymore, because although the performance of it is acceptable, the screen is a bit low res, at 1280x800, it's pretty dark (or at least until it 'warms up' to full brightness), it had a major scratch on the screen, (no idea how it got there) and after buffing it out with many methods, including with an eraser, the area has became discolored, like a portion of the screen has higher gamut and brightness, and lower black levels. :( Oh well. The main killer for it is that it's form factor. It is too big, heavy, the screen is too small, and it is very cumbersome to use far away in the corner of my workbench. Of course being a laptop, the 'base' of it is fixed to the screen, and to move it closer to me takes away lots of valuable space on my really messy bench. I mostly use it to research part numbers, get schematics off of google, watch YT videos, log data from serial ports (including my UNI-T multimeter with basic data-logging capabilities), and stuff like that. I may have as many as 20 tabs open at a time, which did tax my old compaq C700 when it had 1GB of RAM, but that was likely due to a memory leak issue with chrome, since I have the SAME issue with my main desktop, with 8GB of DDR3 RAM. If the video by MAKE is anything to judge, it looks just as powerful, as this embedded video is large! https://www.youtube.com/watch?v=pZz8MW3DSqA My hope is to replace it with a raspberry pi, and be able to use it for these basic operations w/ a old LCD monitor which can be picked up off of craigslist for cheap. Maybe I can even find one in the dump :P. Maybe I can configure the GPIO pins to be COM and parallel ports, w/ clock, Tx, Rx, and everything else! That way an external FTDI chip and using the limited number of USBs is not an issue. Is that possible?

RPi2: OSMC Terminal Issue

I am trying to make some changes to OSMC through the terminal, but there is an issue with the login portion of it. When I quit OSMC, and wait for the boot screen, I hit Esc, and it goes into the terminal. Next, the login. I enter "osmc", then its to the password. But, it refuses to let me type anything in when I get to this stage. If I hit enter, it tells me that my password is wrong and then it goes back to prompting me to login. After about 15 seconds, it just continues to boot into OSMC. Why on earth will it not let me enter a password, and how do I fix it?

Digital Music stand with timed page turning.

I really need to make a digital music stand.  Setting up multiple paper pages on a stand is extremely inconvenient.  It takes longer to set up the music than to play the song!  Plus, even with the arms extended on my music stand, it can only hold 4 pages max.  Some songs can be 10 pages or more. So here's what I'm thinking: A raspberry pi running a program to view .PDFs and a flat screen TV or monitor mounted to a music stand. W. Wayt Gibbs, here --> (http://spectrum.ieee.org/geek-life/hands-on/diy-handsfree-sheet-music) has already built the exact thing that I'm thinking of.  However, I'll be using this for drum music so my feet will be busy enough without having to use a foot pedal to turn the page (Maybe I'm not that coordinated. Definitely won't be chewing gum while playing!) So I'm wondering if anyone has any ideas about automatic page turning. My idea would be a .PDF viewer that can display 3 pages (so that the page turning doesn't have to be exact) and can be set to automatically turn the pages at a timed interval after i click start.  The problem with this is that each song will have a different timing.  Does anybody know of a program that can turn pages via a timer AND remember different timings for each file? I suppose I could just write the timing setting on the top of each .pdf and set it to that every time I open a file. Also, I'm not a computer programmer.  I have built a home theater pc which gave me a little knowledge.  But, when it comes to raspberry pi's I've never used one.  Is it powerful enough for what I'm proposing? Is that the route you would take? I'm also not sure what to use as an input device.  Maybe I'll just mount a percussion table to the drum rack somewhere and use a mouse on it. I'm open to any and all suggestions about every aspect of this idea. Thanks for any help or suggestions!

Raspberry Pi 3 Interactive Led Strip Wall

At the moment we're working on an interactive led screen wall for the entrance hall of our new studio. I've setup the following frame (http://i66.tinypic.com/33ll30j.jpg)  with 17meters of WS2812B addressable led strips.We're using the Neopixel library for rasp (https://github.com/jgarff/rpi_ws281x) and it works like a charm with the rasp 3. Anyway they next step is to control these ledstrips so they work as one big display. I had a look on the internet and a lot of people advices to work with the FadeCandy from Adafruits but I want to know if there are other solutions using only Python and write software to control the ledstrips. The purpose is to use the rasp's camera module like this guy did http://andydoro.com/ledmirror/images/stills/ledmirror01.jpg so when someone is entering the room, his reflection appears on the wall... Any information / tips / other solutions about how to achieve what I described above are welcome. Thanks

Does anyone know exactly what kit i'm going to need.  THere seems to be hundreds of different ways of doing this and I've got no idea where to start.

How do I attach an LCD Screen to an IP DVR Camera Module?

Hi, I have a neighbor who moved in across the hall and brought drama with her in the form of more than one angry drunk boyfriend.  Security and police have been called to their door on more than one occasion and they blame me.  Garbage has mysteriously been left at my door and when they did not know I was listening have made some really nasty comments about me.  For my own protection I would like to install a peephole camera.  Since none of the ones I can find in my price range have both a dedicated screen and an ip camera would like to make one. I have found 1) IP Camera with DVR module like the one in the picture: http://www.amazon.ca/dp/B00STKFDDC/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid;=25HQ29KSVC2OB&coliid;=I5BW4KF2XAIZR 2)  a billion different lcd screen kits, some generic, some for arduino, some for raspberry pi. This would be my first arduino or raspberry pi project but I am willing to learn.  But I think it may be redundant to use an arduino or raspberry pi as all I need is output, but I could be wrong I have no clue. If anyone could point me in the right direction of  an existing project plan or describe how to do it I would really appreciate it.  I have spent a couple nights searching but it is possible I don`t know the correct terms to find what I am looking for. Totally grateful for any help. Thanks!!!

Question by Bhabeshr  


At a stand still in my Raspberry Pi project. Help?

So I have been posting a couple questions concerning the raspberry pi and things related to it lately and I have trying to keep it vague because I'm attempting to build something with the pi and I don't know if it has been done before (it probably has and I just haven't found it).  Anyway, I want to make a rear view camera in my car, like newer model cars come with.  But i Have run into a few problems and i need the great people of this website to help me be able to figure these things out.  The problems: 1. I want to hook up the pi to the power supply in the cigarette lighter in my car, so that when the car turns on, the pi also turns on and boots up.  However, I want the pi to boot up and automatically open the camera preview function (with the Pi Camera Module) upon booting up. I do not know how to do this. 2. The display connection.  I want the display for the camera to be mounted to the dashboard somewhere, but the Pi, with the attached camera module, would need to be in the trunk somewhere, looking out to the rear of the car to actually function as a rear view camera.  So, I would like to connect the display to the Pi wirelessly and I'm not sure if that's possible.  I've seen a few boards and shield that you can mount on the Pi to enable wireless connectivity, but I'm not sure if that would work for a display. My display was originally going to be a screen i salvaged from an old laptop, to keep the price down low, however i have no way to connect the screen to the pi.  So now i figured I'd just put out the money and buy a touchscreen display. So please people help me figure out how to solve these problems, and keep in mind I'm fairly new to the Pi and programming. Thanks in advance!

How to connect a 12v/5v dc converter to a standard 12v plug? And still use the plug?

I need to power both a Raspberry Pi and a 12v touch screen from the same 12v source. I know that I can use a dc voltage converter (like this one: http://amzn.com/B00GQ4DTGQ) to step the voltage down to the 5v for the pi. The power supply has the circular 12v adapter (e.g. http://amzn.com/B00GUBVI9K). My question is how to I attach the voltage converter to the 12 supply, and still be able to use the 12v supply for the touch screen? Thanks!

Advanced Helmet

Advanced Helmet By: Arseny Ratnikov I want to create a helmet that looks like a sci fi helmet (mass effect, titanfall, halo, etc.) and that; **Want to make cool helmet, need help with having multiple camera feed output to multiple screens** * Protects my head (able to decrease force from impact by significant degree) * Can filter the air I breath (does not need to be super extreme filter, just filter out general junk, the better the filter the more pleased I am, but if it becomes too bulky/expensive then it is unnecessary)(Optional/Most Likely) * Has a HUD with my vitals on it. I would wear some sensors, such as HR monitor to have some cool biofeedback, maybe also include other information.(option) * Maybe even have it be a digital display where there are cameras on the front and maye back of the helmet that then are displayed on the interior screen, where I have voice commands setup for some different things. * Have the helmet be as sound proof as possible and have microphones where my ears would be, then inside the helmet speakers, so that I can modify the noise around me to be how I want it to be. I understand this would be rather difficult (at least including all of the bullets) and that it could even be a touch silly. Yet, I find this a rather intriguing pursuit and think it will help contribute to becoming a cyborg. Any tips would be greatly appreciated as I don't really know where to start for this. I can imagine a lot of the work might be done on an arduino, but I simply don't know the feasibility of modifying noises of the world around you and having the cameras on the helmet. So here's a little prioritization sheet I worked out, it is not exactly in order, and maybe you all have some suggestions on what might be more critical to design and functionality. Prioritization 1. Functionality a. Head protection a1. Padding/Inertia dampener a2. Sturdy/solid b. Control of phone through bluetooth b1. In helmet speakers b2. In helmet microphone b3. Voice control c. Control of other systems such as screens c1. Voice control of screens c2. Screen modification c3. Screen HUD and other functions (maybe GPS map, time, etc.) d. Camera view d1. Camera live to screen with little to no latency d1a. 360 degree view compressed to 180 degree screen (maybe) d2. Computer control of camera feed d2a. Visuals, different HUDs e. Sound modulation e1. Sound cancelling e2. Sound reproduction at low to no latency e3. Sound modification e3a. Changing pitch e3b. Change decibel levels e3c. Change relative level of external sounds f. The HUD f1. Display of vitals f1a. Heart rate, oxygenation, etc. (Requires some monitor) f2. Display of time and other running interests f3. Display of current location on google maps/GPS system g. Air Filtration g1. Filtration of air, relatively high quality g2. Seal on head or seal over mouth and nose or full body suit that connects to helmet h. Extra Features 2. Style a. Look good b. Look like popular sci-fi media c. Does not interfere with functionality and accents functionality How should I do this? I am planning on using some old phone screens if I can for the screen part and multiple cameras. I plan on using a raspberry computing system (might need multiple) to modulate the output from the cameras. How could I make multiple camera outputs lay onto multiple screens that looks good at three to five inches from the eyes? Also how can I make the raspberry pi control my phone and computer via voice, or at least change a screens properties? Thanks

can i send serial monitor data from ESP32 board to B+ via Bluetooth?

Hello guys how are you doing ?so I'm currently working on a project from long time ago that was devastating and depressing for me , i will tell you the idea and what progress I made through the past 6 weeks and see if you can lead or help me ,, so the idea is I'm currently connecting esp32 Arduino board with six senses , 5 of them are flex sensors and one of them is the mpu6050 sensor which reads the angle of x y and z I was able to connect those sensors to esp32 and read all the values on the serial monitor as you can see below the code and the serial monitor https://ibb.co/92qBsh0, now my next step that I didn't know how to do is : I want to send those data, the serial monitor data continuously every 6 second to raspberry pi via the Bluetooth of the esp32 to the Bluetooth of the raspberry pi in order to program those data , i want to program those data to an LCD and a speaker ,For example if I received the following values from the esp32 I want the Res pi to put a certain word to the LCD screen and and then convert it to speech through the speaker , I already connected the LCD to the raspberry pi. , but now how I can send the serial monitor data continuously to the pi so I can program it

Sub-mm precision ultrasonic or inductive distance sensor for use with Raspberry Pi?

Hi there, I am trying to keep my hardware/ coding skills alive and spruce up my bicycle wheel truing stand. I need to figure out the required hardware + software for the following: I want to build a non-contact distance measurement sensor system and get the output "into" my computer for display in a graphical user interface. I know I could omit the latter step with going directly onto a mini-LCD screen, but trying to use this a learn-another-programming-language learning experience (I've coded Matlab galore, pondering Python for this project). General system components: Sensor - [something - RasPi or Arduino I guess] - laptop (running debian) - GUI displaying continuous sensor reading Sensor: I've web-searched the hell out of this, but not finding anything quite answering my questions. I want to continuously measure the distance from the sensor to a bicycle wheel rim braking surface. Material is aluminium, shiny, though not smooth. Biggest problem with the web-search is being swamped by proximity sensor results (on/off) rather than a distance proportional output signal and much lower resolution projects. I rule out IR or optical sensing, now stuck between ultrasonic and inductive sensing, though tending to the latter for a faster response/adjustment to change time. Sensor criteria (other than reasonable $$): - total sensing range: ca.5mm - sensing accuracy 10 to 100micron/ 0.01 to 0.1mm - don't ask if that's needed, a bit of overkill, I know, but a bit of OCD doesn't do any harm, eh? - fast-ish sampling rate (so that when I turn the wheel, the number on the screen updates nice and fast, guess >25Hz is sufficient). [Something - RasPi or Arduino]: I know that I could omit the laptop GUI part (mini-LCD, LED array, etc), but keen to learn/ practice a little Python with this project, so I guess I am tending to the RasPi, but I am open minded. All I want is the analogue sensor out to end up as a digital reading "inside" my computer to be passed to my GUI as a reading. Essentially a mini A2D converter. Not fussed whether the output is in actual distance units or in arbitrary units/ current units (I guess the sensors put out a proportional current signal?). GUI: Depending on the above, how do I best get the signal "into" a Python program? A moderate fast sample rate >25Hz should suffice. Any help with this would be greatly appreciated!

Idea: piPod, piPad, piPhone

Okay, so here's the idea.  Inexpensive RaspberryPi computers have lots of horsepower, an SD slot, audio jack, and place to hook a screen...  Why not kludge together your own iPod or even iPad.  Also, slap on one of MIT's cell modules and you've got the iPhone. Sure it might look funky and may even cost more than the real deal, but half the coolness is just to say you did it yourself! (P.S.  Since I just coined the terms piPod, piPhone, and piPad, you've got to send me one if you make it work!  Please?  Pretty please?  Maybe??)

Battery Powering an Rpi3 and Monitor?

So I have plans to assemble an Rpi3 laptop with a battery and display and all that. So I need a way to battery power my Pi. Could I power my Pi3 (5v@2.5a) a usb power bank (one that could provide 5v@2-2.5amps obviously) with perhaps a step down/set up regulator? But I still would need a way to power the screen. Most driver boards want 11-12v and I don't know how to provide that. Maybe wiring batteries in series or parallel? I'm not exactly sure on how that works but I'm new to LiPo's so I'd like some help please. Thanks!

Sciences PI Plate

Hi every ones, I'm a young engenner in plant biotechnology. On my free time i try to create an open source plate for the Raspberry pi which has lots of functionality very usefull for science project (Plant growing, Invitro cell, hydroponic control, compotemental study...) I'm really a beginer in electronics, but i read a lot electronic book, looking schematic and see video. This plate have : -8x relay 220V 5A control by a Darlington Array -8x Analog input -4x BNC connector connect to 4 Atlas Scientific Stamp (Ph, EC, DO...) -RTC clock (to be sure of time when data are store on database) -LCD screen 16x2 to facilite the reading without computer -This project will come with backend/frontend distribution Before i order all parts and PCB, i wondering if you be able to check my schematic to validate it and maybe improve it  :P Schematic Image files (2Mo) Fritzing file FZZ I have few question too  : 1/ Can i connect all my ICs and LCD to my external power supply, i read on internet this is better than connect on the 5V from the Raspberry PI? 2/ If i connect all 5V on my external supply how many amps i have to provide (the sum of all amps require by parts)? 3/ Do you know an I2C IC can replace the 74HC4052 to make all the plate in I2C and made it usable by more than a Raspberry PI ? (if it interesting) 4/ Which width is recommand for the wire on my pcb 24 mil (or smaller), and for the 220V Relay the biggest ?? Thanks you for your help, and your website ! Regards Erwan

Where would I begin if I wanted to create a commercially available gadget (Think home automation)?

I have an idea for a gadget that I would like to market. Lets say it a home automation system with a touchscreen where you can play bluetooth music, read Rss feeds etc. Where would I begin to make it? I have indepth experience in programming but I don't understand what system I would build this upon. I doubt I would go out and buy a raspberry pi and design it on that because that is their own hardware and OS that is not mine? I fee like an Arduino is not powerful enough for a clean and intricate UI with a touch screen. Does anyone know what system/board I would use for this idea?

What should I buy to make a tablet?

I'm trying to build a tablet, I'm planning on making the case out of wood. I want to be anywhere from 10"-13". The tablet needs a usb port for plugging in a controller or mouse, a Hdmi port for plugging into a tv, a way to charge it, Wifi, memory need to be run by a sd card for weight and size, ram 4-8Gbs and bluetooth. I don't now what motherboard to get and where to buy a touch screen. I also want to be able to install any OS I want. I was thinking about getting a Raspberry pi but it wont allow me to install just any OS and the memory was too low. I also don't know what kind of wood I should buy for the case I want it to look cool, I'm also going to burn a logo on the back of the case.

Building A SHTF Computer Using This Pistol Case, Need some Advice

So some time ago, i was at an Academy store and did an impulse purchase. Spent $50 on this durable, watertight pistol case as seen in the accompanied image. For a few weeks, i have just let it sit in my room and thinking about what to do with it. Then i thought "What about a Portable PC?". So i did some measurements, the interior is roughly 12x9x5 inches in Length, Width, and Depth (if you count the lid's interior). At best i have some components, such as a 10 Inch screen from an old netbook, i already have the controller board to make it a regular monitor for a few purposes. But a few things im not clear on is what components would best fit this case? I know its too small for most motherboards, and im not intending to use a Raspberry Pi or a Linux OS. And i also want to do as little drilling or cutting into the case as possible to retain its moisture resistance. If i had to list any criteria for such a build, there would be: Information Storage Connectivity to Larger Screens (aka stationary "tower") Wifi Capability Emergency Power Source Thats just off the top of my head, tbh. In short, im wanting to make a utilitarian computer that could survive (and possibly thrive) in a disaster situation of non-biblical proportions, all crammed into a case that was meant to hold a handgun. Keep in mind i have little to some electronics experience, but i have built a pc before. So who has any advice or what-have-you to point me in the right direction? (i hope this evolves into something pretty dang good. i do believe its kind of a challenge to pull something like this off, going with a case roughly half the size of your standard PC tower)
