A new blog post from ED, and a official hackers manual!!

http://www.openpando...manual_v100.pdf

Here's the post if you're interested:

Phew - just answered over 100 eMails to day and did now catch up with my Inbox.

notaz and me also did work some more on HotFix 3, while DJWillis is currently setting up the official Pandora repro (including sourcecodes).

I'm also trying to catch up with infos about what happened in assembly (news you're all working for).

I'll post a longer and comprehensive post within the next days - also including infos about what you can expect with Hotfix 3 (which should be ready next week)

But I got some nice little interesting document for you guys today:

The official Pandora Hacker Manual v1.00, straight from the creator Michael Weston himself!

Enjoy.

Be sure you know what you're doing though - we take NO RESPONSIBILITY if you kill your Pandora while hacking around!

Confirmed : Some mixed up numbers on "spare LEDs" (p.4)

It should be :

- LED7 --> TP22, Q17, R165 & R166
- LED8 --> TP23, Q18, R167 & R168

Edit: The last schematic is a good example of getting things done imho
Edit2: Confirmed bit (see 4 posts below)

Whoa, that's beautiful! Especially love the hand drawn diagram on page 21... I'm going to study this a bit...

[Line O'Sevens]

See if you can get one of these for your iThingy! HA!

[urjaman]

Nice

NOTE @MW (for next version): put the Nub AVR ISP header pinouts there, too.

And yeah the LED7 and 8 transistor & resistor numbers seem swapped in the text, as noted above.

[MWeston]

If you start from the LED tag, it should probably be as follows :
- LED7 --> TP22, Q17, R165 & R166
- LED8 --> TP23, Q18, R167 & R168

You're right, I did mix them up a bit. There was some cutting and pasting at one time and I screwed up the order. What you list is correct and I have modified the document. Thanks!

NOTE @MW (for next version): put the Nub AVR ISP header pinouts there, too.

I can do that but the code should be protected (if the fuses were programmed right by the company that did them) and you would have to erase them to change the code. I still don't have any permission to release a binary or anything.

....
As i've joined the one-nub club, I just MIGHT (someday) be upto erasing one of the AVRs to develop a free alternative on. Still, it is a HUGE leap of faith to just think "OK, I'll just erase this nub controller, ought to be simple enough to code new fw from scratch...", and I consider myself a relatively good AVR programmer*.
I'm wondering what the big secrecy around this nub tech is about.
Are you allowed to give a pinout of the world (what is attached to me and in what pin) from the AVRs point of view?

Spoiler

*(spoiler because of OT) I want to float here a bit, my AVR stuff:
- Stereo 8-bit LPT sound card from an ATTiny26L, two 62.5kHz 8-bit PWM channels, on-chip nearest neighbour samplerate upscaling (written in assembler, binary size 426 bytes)
- Firmware to a bluetooth controlled RC car (quite simple actually).
- One flash chip programmer fw, another one unfinished (theres a external programmer driver in flashrom for these).
And a lot of fiddling around thats not worth much mentioning.

Thank you very much MWeston! I was not expecting this at all, I think you have probably saved me hundreds of hours of misguided reverse-engineering. I am definitely going to make use of this document, as I am all about LED mods. I would also like to make use of the Expansion Port at some point down the road, maybe for a Pandora-bot of some sort, but yeah I'll have to get my Pandora first....getting a little ahead of myself. Anyway, Thanks again!

MWeston, you are incredible!

[panik]

I love you.
We're going to have sooo much fun!

[Alerino]

will you guys be offering pandora add-ons?

[SomeGuy99]

I love stuff like this that I don't understand!

[Canguy]

I just wanted to confirm something concerning the expansion port pinout. If I read the diagram right, that is looking end-on at the plug on the end of the cable right? I don't want to muck things up.

[Gruso]

This is awesome MWeston.

Sadly I can't log in to the blog to post anything right now. Hopefully it's fixed soon. Fixt.
