Help build a mini e-reader with arduino, lcd and micro SD card?

Hi all, I am wanting to start a project to make an e-reader. It will comprise text files on an SD card which are then read and displayed onto an LCD screen plus the ability to scroll up/down (and/or left/right). I plan on using a DOGM204 lcd module and probably a pro micro (sparkfun). I would really appreciate any help as to how I could make this.

Anyone know where to buy some really cheap USB flash drives or MicroSD cards?

Frenzy's instructable on USB dead drops got me inspired, but I don't want to set up just one!  I'd like to set up several around my little town here, and I don't want to break the bank doing it.  Does anyone know where to buy maybe six to twelve thumb drives or micro SD cards for super cheap?  I don't need anything particularly fancy, I'm sure 512mb or 1gb would be plenty of space.  I found some stuff on ebay but I'd still be paying around $35 for 10, and I'd like to get that down around $2 each or less.  What do you think?  Pipe dream or do you have some ideas?

Nexus 7 (2013, Gen2, FLO) - internal micro SD mod

With games getting bigger and bigger with every new release and limited storage capacity some of you might think the same: Why not add a SD card to my Nexus 7? The lates Lollipop update basically killed the normal USB OTG funstions, so if you do want to use a USB stick or external SD card in a reader you will need a powered USB OTG cable. I am not sure if this was intentionally or another bug but it is damn annoying. After openeing my tablet to check m options I realised my main problem is space. Even adding a micro SD with a similar small reader is a major pain as there simply is no empty space left inside. So I was hoping someone here might be interested in such a mod and contribute with good ideas during the build and maybe even copy the mod (if I manage it) to confirm it is in fact doable. My findings so far: A custom rom is a must have due to the OTG limits of the original. It might be enough to just find a suitable kernel but so far I settled for the Team UB Lollipop release. It offers some mods based on Cyanogen and claims full OTG support. Other roms also added support for external WiFi and TV dongles, so there is room to play. As said space is a problem I am working on ;) For an internal mod and due to the lack of physical support on the mainboard the only option is to use the standrad USB port for this mod. This means SD, reader and OTG mod must fit inside somehow. It also means some sort of physical switch is required for the times when you need full power during the recharge - although I have to test if this still works with an external SD while the tablet is switched off. In that case I could accept 500mA charge during normal use and 1A or more when the tablet is switched off. The rom should support fast USB charge but I am not sure if this olaso works in host mode. It is possible to use some extra app and scripts to make good use of such a mod. Not only can you use the SD for music, movies and other demanding files but with scripting you can also move the big data files from games to the external storage. Works similar to the apps you can get for devices with a real SD card, where you often find the "Move to SD" option in the app manager. This mod will not be for the faint hearted as it requires serious soldering skills on these tiny components, so if you only know how to solder copper pipes you might need some training on old electronics first ;) Let me know what you think and if you would be interested in such a mod as otherwise I won't bother taking pics during the progress. And without pics there will be no Instructable follwing ;)

64 GB compact flash cards

How do i identify drone camera wires?

Hi I have a small drone which was run over, but the camera survived and i'd like to re-purpose the little camera. The camera has only three wires on a connector, it has a space at the back for a micro sd card too. On the pcb where the three wireds are connected the black is marked vb-, the red is marked vb+ and the blue wire is marked P12. Obviosly vb+ & - are easy to desypher. Can anyone help me identify the P12 connection? Would this be a trigger wire of some sort and how do i connect it to actually trigger between capture picture/capture video/off? Also, is it safe to assume that if connected correctly, that this camera can work as a stand alone camera with no other interface being that it has a slot for micro sd card? Thanks in advance for any help :)

'Hacking' old advertisement touchscreen from Avengers display

Can anyone give me some advise on how to go about using this for something more useful? It's a touchscreen micro-computer of sorts that has an SD card installed. On that card are several videos files that run automatically and upon touchscreen prompts. I'm thinking that it'd be nice to upload a video for the applicable season (think Halloween theme) and place it in my window so passers by can admire a scrolling video of something amusing. The SD card is a 4GB card and is only partially used (just over 3GB free)

can i mod a memory stick pro duo adapter (psp memory card) to instead fit a usb stick or maybe a SD card?

Im trying to find a way to modify a memory stick pro duo adapter to fit a standard usb stick or even a SD card. the reason for this is that i got ripped off on a online perches for a psp memory card adapter to fit for a MicroSDHC which i could use, but it instead it uses a micro M2 card, i do not own one of these, nor do i have the money to get one (tight on money), so i was looking around for the pinouts of the adapter and for USB and was hoping i could solder the like pinouts of the two to each other (do have proper soldering skill) so that when finished i could have a memory stick pro duo adapter that would adapt for a (preferred) usb stick, for my psp. any ideas?

Code to draw Graphic on nokia 1202 LCD (STE2007 driver)

I've bought a nokia 1202 LCD recently (very nice one, have their pinout ready to use, micro SD headers and a regulator). I've tried hard to find an library for it, and finally found one that's usable. Now printing text is no longer a problem, but graphic is one big mess. Can anyone help me with it? I've already make the image into an array, but stuck with the "display the logo" part. Apparently, the number did something, but I don't know what. Everytime I tried to change it, the screen output something different. I've included the library (which I downloaded it somewhere on the net) and the code I've modified. Thanks in advance, and sorry for my terrible english.

WTV020M01 sound module need help

Hi I recently bought a cheap WTV020M01 (WTV020SD) sound module from china. i know you get what you pay for but i cant really afford to spend big on that kind of electronics or else i would have. Any ways my problems is i have wired up the component as instructed, loaded up the audio files as per instruction on the micro SD card and connected it to power and hit the play pin. And NOTHING happened. i then tested to see if it was getting power and yes the power was fine. After being frustrated i tried moving around the power connector and discovered that if i placed the power in the reset pin the module lit up as if it was working and all the buttons worked but still no sound. i am not sure that as its a cheap component its a dud or have i just wired it up up wrong, or an i missing something like an amp. any help would be good thanks. here is some links to the component specs http://www.datasheetq.com/view.jsp?pn=WTV020M01&fac;=ETC⟨=en

OggVOSH: The (soon-to-be) Open-Source Ogg Vorbis Player

I've been eying the VS1000, a little bitty chip that is basically an all-in-one Ogg Vorbis player, just add a crystal & memory. Its so beutiful, so tiny yet so complex... it even has a great default firmware. I've finnally got around to making this. I'm sending the PCB off to be made, and getting parts to prototype. Stats? Size: 2.19"x1.48", roughly twice the size of a new shuffle, or half the size of a new nano. I haven't figured out depth, but it uses li-on batteries, so it will not have a lump on the back, it should be comparably thin.Capacity: uses microSD cardsConnections: 3.5mm stereo headphone jack, microSD card, and miniUSB. Via miniUSB, you can charge the battery, as well as read/write to the SD card.Audio Support: Only Ogg Vorbis, but then again, it is the best codec, you can convert everything to it ;-) Max bit rate: 500 (beat that Apple!)No screen :-(Cost:This is tricky. For me, if I didn't buy any spare parts, its going to cost me $100. If I had an SD card, it'd only be $80. If I semi-mass produce them (more than 20), I know I can cut at least $10 off that price.So, it pretty much beats the Daisy, our, the OS/DIY community's, current audio device all around. Except one thing... it isn't a beginners project, involving nearly all SMD components, the only exception being the headphone jack. And the main chip is a bit of a pain to solder -- 12 pins on each 1 cm side ;-)Still, I think this is promising... along with my micro-POV... in making things smaller, like the "real" devices :P

RPi Zero and GameBoy - Can the New & Old Work Together?

So I recently found out about the Raspberry Pi Zero earlier last week. After looking at the size of the board and comparing it to the size of a GameBoy/Color/Advance/SP cartridge along with the back of a Gameboy Color/SP system, I had an interesting thought. I know that the RPi's have a great use as a video game emulator (with some case or hardware modification to the original gameboy system). I even saw one DIY article that had a GameBoy cartridge hollowed out and a Micro SD card adapter put into it, just so a heavily modded GameBoy Brick with most of its guts replaced with other techbits (mainly an RPi Zero and plenty of wires) could be used to play NES, SNES and GameBoy games while on the go. So since the Zero is slightly larger than a GBA cartridge, would it be possible to make the Zero connect to the hardware of say a GameBoy Color via the cartridge slot on the back of the console? Or what about other RPi's with other GameBoy consoles? I would try to find out about this myself, but i missed out on buying a Zero when they were first announced and i dont want to buy one from a scalper.

RetroPie system hanging problems

Not too long ago I ordered a Raspberry Pi 3 and used it as my main computer for about a day and while it did most things pretty well, internet browsing, as usual, was painful, with the browser tabs loading very slowly and crashing frequently, probably due to the small about of RAM and poor RAM management. Anyways I decided that while the Pi 3 may still not be suitable for me in desktop use, what about game emulation!?!? ----------- So I download the RetroPie distro and flash that to a quality SD card, and get it set up. I installed a few experimental emulators and messed with the CPU/GPU RAM allocation a bit but any time I try to emulate a system, or even exit an emulator and get back to the emulation station, the entire system hangs!!!! Being a hardware guy, I get the osciloscope and measure the power supply. I did notice that when the PS3 is connected via USB, the red light on the Pi goes out. Surely enough the red light goes out because the nominal 5V input drops to below 4.5V, which causes the 1.1V regulator powering the processor to drop out for some reason. I replaced the dodgy 6 ft USB cable and 5V 2A power adapter with a much shorter 2 foot long and thick micro USB cable and use a quality samsung 5.3V 2.5A charger, and this seemed to fix that problem and reduce the frequency of system hangs. Now I can no longer observe a correlation between a system hang and low voltage dropout. The minimum voltage observed was 4.8V. However I still sometimes get system hangs when exiting emulators, and it is just about guaranteed to hang when trying to use the SNES, N64, and PSP emulators. I might try to reflash RetroPie over this weekend if I have time, but I want to know if anyone else had this problem or might have a solution. The SD card used was a 32GB SONY UHS1 card nominally rated at 40MB/s transfer rate, and benchmarked the highest of all my 32GB cards with 4Kbyte random read/write. I used Win32DiskImager to flash the card in windows 10.
