Where has moogle been? Why did every thing suddenly stop?

Back In 2011 I was going though some tough times trying to get help with my work related back injury. It had gotten to the point where just sitting down was unbearable. I had just got home from a session of getting cortisone shots in my spine, when speedfan started warning me of hard drive issues.
http://wtfmoogle.com/wp-content/uploads/2011/08/failingdrive.jpg
 Being medicated out of my mind I could only sit and laugh then went to bed (a very bad mistake).

During my slumber the drive crashed hard, so hard the drive next to it was now failing. Thus my raid 5 was doomed.

I tried for months to recover any data. Copied the drives to new fresh disks and used multiple tools with the help of friends and family.
http://wtfmoogle.com/wp-content/uploads/2011/08/raidsetup.jpg
http://wtfmoogle.com/wp-content/uploads/2011/08/fixraid.jpg

Every attempt failed. 3 years of code, music, circuits, designs, notes all lost...

Being on all the pain killers wasn't fun and it got to the point where I had trouble even soldering headers onto the DJHI so I stopped the sales.

I've finally managed to get though the pain and buy a decent laptop. and clean up my lab more http://wtfmoogle.com/wp-content/uploads/2013/01/DSC00260.jpg

I plan on starting sales of DJHI again soon and I am working on a DJHI with a ESP8266 module wifi connectivity :)

I really want to try and revive the community again

Yea that would be great. I don't know enough to do more or I would.  I can connect to the device through the leappad manager that me and is0-mick made and I created a theme maker, but would really like to see some emulators on this thing and custom firmware :)

I have my preliminary sketchout of my DJHI Nand Hacker Edition PCB, just waiting for etch solution to arrive, just before i etch it, does anyone have a Gerber file or alike PCB layout file already to hand? That's not to say that mine won't work, but it would be nice if there is one already made up...  I'm thinking about adding an STM8 onto the board with a button for enabling/disabling developer mode through ttl but before i solder anything down can anyone else think of a useful command to add? and make my button dual purpose...

here is the original schematic. I believe there is a mistake it in. this was done late at night so it was quick and dirty. http://wtfmoogle.com/wp-content/uploads/2010/10/djhinhesch.png

I was also working on a compact flash version
http://wtfmoogle.com/wp-content/uploads/2010/08/cfDJHI.png
and a xd card version
http://wtfmoogle.com/wp-content/uploads/2010/09/DJHI30.png

I even had an expansion xd card board i was working on that failed horribly as i messed up the pinouts to the xd card
http://wtfmoogle.com/wp-content/uploads/2010/09/DJHI-Ev1.png

this one the xd card was backwards and didnt have enough room to slide into the system
http://wtfmoogle.com/wp-content/uploads/2010/09/vxd10.png

had a ton of these made but the pin out on the xd was all wrong for power :( http://wtfmoogle.com/wp-content/uploads/2010/09/xdbreakout.png

I was working on a bluetooth enabled djhi
http://wtfmoogle.com/wp-content/uploads/2010/10/bt.jpg
had working breakout board.

The DJHI nand hacker edition did work.
http://wtfmoogle.com/wp-content/uploads/2010/09/DSCN5444.jpg
I was even able to make a factory test cart from the files originally left on the units.

I was also working on a breakout board that would let you have your own bread board hanging off your didj / explorer /lp

http://wtfmoogle.com/wp-content/uploads/2010/09/DSCN5443.jpg

It worked very well
http://wtfmoogle.com/wp-content/uploads/2010/09/DSCN5442.jpg

concept art for the breaker.

Here is a full high res scan of both the front and back of known good DID NHE and the breaker

On top of that I was working on a Flash Upgrade Kit
FUK

http://wtfmoogle.com/wp-content/uploads/2010/09/fukv1.png
an embedded flash upgrade you could solder inside your system

One of my ultimate dreams was to add another uart via a spi adapter add a gps to that and a odb2 reader to the usb to have a full car gps + diagnostic unit.

http://wtfmoogle.com/wp-content/uploads/2010/07/gps3.jpg

spi - gps sd card adapter http://wtfmoogle.com/wp-content/uploads/2010/07/mSDGPS.png

I was even working on a simple usb adapter for the explorer
that would be cheep and easy to install with on board 5v power boost circuit
http://wtfmoogle.com/wp-content/uploads/2010/07/adapter.png
http://wtfmoogle.com/wp-content/uploads/2010/07/adaptusb.png

I hope this helps and explains some missing info on the wiki

Jason,

Is there a OpenLF wiki of which to add how to do things?

Due to a lack of interest and me just having other stuff to do, I'm going to close down the community, in a week or so, unless someone wants to take over. Anyone is free to, just let me know, I can transfer ownership.

Did anyone ever take the job?  (Not that I'm volunteering, I just noted that things seem pretty active now... I'm hoping anyway).  Both of my girls have Leappad 2s and I'm interested in modding a few things in... One, a timer to shut it down after a while... 2, They say you can have apps on more than 1 device, but I can't figure it out with their stuff and I find open stuff much easier to deal with in general.  So I'm hoping the community is still active even though its been a while since Leapfrog has created these (not that they don't have new stuff, but I did read they are getting hammered by other types of devices, which is a shame).

This years new product, a wearable. No idea if this is running Linux or what, my guess is probably not. From what I can tell it has some basic animation sequences, and is mostly a data logger/simple game machine. If anyone knows different, let me know and I'll post up the specs.

Not familiar with G+ but was curious on any developments of a custom kernal for the LP2 to get a nes emulator playing, or even simply loading via an "app"

Yea read that and it says it works on the LP2, but needs button mapping and he was going to post an image when he had it working in a good way.

I've started working on a buildroot for the new hardware and figured I'd take notes along the way. This is more than likely the beginnings of a how to for the wiki, so any tips, tricks, better set ups, and suggestions on demystifying the process would be great.

I still have about a dozen unopened Didj units. It looks like there isn't much work on these anymore (there weren't very many made in the first place). Is there any point in keeping these? Compared to the Explorer, the 32MB of RAM makes them pretty limited.

Whats inside that blob chip in the original leap frog units?
http://wtfmoogle.com/wp-content/uploads/2013/05/lfsomething.jpg
I decapsulated it with some nitric acid to find out.
Looks to be some sort of flash chip
http://wtfmoogle.com/wp-content/uploads/2013/05/lfsomething1.jpg
best info I could find off the chip die
http://wtfmoogle.com/wp-content/uploads/2013/05/lfsomething6.jpg

fyi the LF1000 has some sort of top later to protect from decapsulation

Wow, hard core RE.  Nice.  It does look like quite a bit of flash.  Could you tell if it was NOR or NAND?

I may have a few LeapPad 2s with various issues.  If someone wants one and can cover shipping costs, let me know.  I can mail them out Priority mail in the USA for $6

i have had a look through the wiki's but i can't find out if there is a CLI command or something that i can use to stop the Leappad from automatically shutting down after a certain amount of inactivity... if there an application i have to kill or echo a timer value into a proc interface somewhere?... anyone know?

Hi All,
Just got my leappad 2 and going through disassembling it.

I have ttl serial working. I figured out the developer mode and have Ftp working.

Been able to dump my Mr. Pencil game and put it into flash and then run it without the need for the cartridge.

Just trying to make a new background and add it to the current list of backgrounds, but every time I drop it in and reboot it, the leappad says I need to reconnect it to the PC. So I ended up repairing the installation and then starting from square one.

Currently drawing up pcb design for my own version of the Didj nand hacker edition cartridge as no one seems to have the pcb design files for version 3.0.

Has anyone else managed to put on a custom background onto the leappad 2? I know about the md5 sum in the package file and the order list that exists in the other file on the folder with the background swf files.

Richard

Hey all, I've picked up a few leappad2s to have a play with and try interface with an arduino etc.

I've been poking around and I've spotted a built in developer mode in /etc/init.d/rcS

It looks in /flags for a dir named developer

If the dir is there it enables a usb network and ftp and telnet servers.

Sadly I've been playing and semi bricked mine. I've tried recovering with surgeon and the leappad software but no luck, could do with some pointers to get it back to factory to start again.

Awesome, good to hear, let us know what you get up to.

I bought my son a Didj at a store close out in March 2013. I put it away in a closet until his birthday Nov. After only a few hours of play, it was having problems, wouldn't sync Bitz needed connecting to the computer, etc. So I call Leapfrog to get some help, they tell me it's toast and out of warranty. I felt awful he had it for only a day, and there was nothing Leapfrog would do about it.

I got it back up and running and stumbled across the eLinux site, etc. Found out how to take a copy of the USB drive portion of it and was going to do some comparing of the drive to figure out where the "Bitz" were being lost.

I thought while I was doing that I'll flash EmeraldBoot and when I want to I can use the three button push to get into it. The part I read didn't include the little tidbit about boot panic because it would no longer find the Didj.

That started my journey.

More Buildroot.
http://blog.mechcalc.com/buildroot-02-init-to-win-it/
http://blog.mechcalc.com/buildroot-03-left-to-our-own-devices/

Continuing on I wrote a couple basic posts about Linux init dev/ proc/ and sys/ and an option for dealing with the old hardware's lack of devtmpfs support and Buildroot expecting it to be there.

Requests, corrections, what ever, let me know. Hoping to demystify the process for new people and myself.
Init. Previous Article: Buildroot 01: The Rocket Surgery Part. At this point, the bootloader has initialized the low level stuff required for the kernel to start up, and got it up and running. The kernel is loaded into memory and has taken care of it's tasks, so now everything is ready to bring ...

Ah that sounded familiar, thanks for mentioning it, there is a couple choices for the init system, Busybox, SystemV, Systemd, or None. I figure later I'll try some different stuff out.

Tools: Meld
http://meldmerge.org/
Earlier tonight Jeff tipped me off to this GUI file/folder diff tool. It worked really well, if you're still just using diff, I suggest giving it a try. Meld compares the files side by side, highlighting what is different. For directories it shows a tree, opened to the files with differences, just click on them, to inspect their contents. I was able to navigate a kernel with much ease, highly recommended.
