Anyone here into designing their own pcb?

hello readers,

greetings!

i am practically a newbie and also a re-entrant. I was
into bitcoin mining back in those days when cpu mining
was the name of the game.

but it migrated from cpu to gpu and then from gpu to
fpga and fpga to asic and basic asic to advanced asic.

I am more or less a DIY chap!

so my question here is? anyone here into pcb design and
fabrication?

or let me rephrase it. has anyone dared to venture into
screwing around with the various cad files and then modding
and then getting your own board fabricated by yourself?

if so share your experience. I am planning to play around
with the pcb stuffs.

if anyone already working on this, please share your
experience, misfortune/success, rambling, rants
and raves. i am all ears.

thanks!

p.s. did you mass order this chip? if so, how much will you
charge me? i need 8 to play with.
these folks dont sell in 8-10 quantity but 500, holy shit! ;-)

I took a look at the Litecoin code yesterday. It is about a months work for someone like me to fork with very minimal exposure to C ++.

Anyone else who can fork LTC to make an Indiacoin in a faster timeline would be awesome.

We can manage a strong marketing campaign to gain adoption of this as it is based on CPU/ GPU mining.

If it fails, would have atleast been a good project to try. Smiley

well, i dont mind coding on indiacoin/desicoin. but at this very
moment i am stuck with way too many projects. may be in the
near future i might show some deep interest and dig in deep.

plus ccie, theory and lab, due in june if i feel confident enough.
else august end for sure.

but i dont understand economics and politics extremely well, esply
economics. so if i understand the economics well enough i can
adapt myself from the bitcoin code and fork away with something
truely desi.

main problem with me? i am a total big 0 in economics.

thanks!

guys com'on, politics!!! regardless who wins India will always have corrupt bureaucrats, and people in power who once in power will do any thing to stay in power.

We can all see who supports whom. so lets leave it to that. politics is all about propaganda, the less you see the mainstreem media and look your left and right you will know the truth.

Infact why not take a stroll out to the market and come back home. Count the numbers of beggars and homeless you see. If the number is 0 then you live in a  perfect country if not then its time for  every one to look beyond the boundaries of race cast and religion and look into humanity, and question the government system we live in.

Now my rant is over.

BJP highly supportive of religious right. That being said, is not a good thing for a secular democracy.
Congress secular in ways but has lost it way and now the blind leads the blind there.
AAP too small, trying to achieve the impossible, being crushed by mainstream media and big business. Dont think they would be able to make much of a difference in the  government atleast for another 4 years.
Others. many parties started out for a good cause lost it way and now they have become institutionalized in the current political system. (AAP may fall into line this if not checked)

Who do i support .  i support no one.  I dont like fighting with my brothers in are over political differences, race and creed. Fuck the system i say. If you are into bitcoins then you are one of a kind, a thinker, a revolutionary, a rebel, the one who stands out from the crowd .

there i go again with my rant so i am gona  shutup....
 

+1

how about NOTA?

and

"guys com'on, politics!!! regardless who wins India will always have corrupt bureaucrats, and people in power who once in power will do any thing to stay in power."

EC gives us power to NOTA, may be soon power to recall or RTR for ministers also. who knows.
application costs 20 Rs and must be filed under RTI act and a processing fee of 20 INR.

hth!
thanks!

grsec is nice. custom kernel and signing binaries. its a massive job.
avoid binary blobs, you dont know mike whats in the blob.

audit the source and package, use IDS (NIDS/HIDS). audit binaries also.

use decent network devices like something which gives you sources.

switch to opensource networking devices. viz openwrt or debwrt
to protect your network(ing) assets. if your networking assets are
compromised when no matter what you do your system will also
get eventually compromised.

"audit your system and network on 6 hour basis. " automate this
process.

ask application/device vendor for the source code. and audit it.

lastly the bios. its a PITA, try to go for devices which support the idea
of open source bios. disable computrace. computrace is a menace.

lastly security is not a blackbox device, that you install it and forget
everything else. you need to be proactive and must audit it to your
fullest capacity/capability.

look for the hardening guidelines, if you harden your OS, thats
the first step. then harden the hardware second step. then harden
your networking applications viz routers and switches.  then harden
the operation. use strong authentication methods. and lastly have
preying eyes to know who is preying on you. this proactive
approach can help you more than anything else.

lastly look for more information on the web, on what is the threat
scenario and what is/are the counter measures.

hth!
thanks!

hello manekari,

greetings!

dont worry about my way of doing an operation. I never
get it right at first place, then i get up and learn from
my mistake and get it right.

cpu and system board? i am extremely well versed.
especially the blackberry ones. they are the most bastard
system boards i have ever seen.

they literally hide the debug ports except uart via usb
finding the traces on this system board is one heck of
a research project on its own.

there cpu has got 530+ pins/pads and those pads leads
to traces on board. and the TI (texas instrument) even
got pin muxing tool by which the jtag and other debug
ports can be completely shut off.

so you must attack the x-loader which is signed using
TI's m-shield and it stores the data in the cpu in a 128 bit
memory flash called e-fuse.

this cpu got an RTOS which kicks off the rom boot code,
which then kicks off the x-loader, where the signature
and/or authenticity is verified.

and after its verified it send the go signal to the
bootloader or secondary bootloader. this then initiates
the kernel and the OS loads off.

the e-fuse is a special memory cell present inside the
cpu which literally gets blown apart when a specific
voltage is passed say 12-15v dc and thus seals any
further mode or method of modifying the boot sequence.

e-fuse is present in omap3x and omap4x HS cpu chips and
in omap3x and omap4x GP chips this e-fuse is absent.

HS = high security and GP = general purpose. we can attack
the cpu code execution via jtag, but i am well versed with
blackberry and they remove all jtag professionally even
uart except uart via usb.

which leaves me with 2 methods which are SCA and DPA.
SCA is side channel attack and DPA is differential power
analysis.

sca and dpa are full proof method of cryptanalysis since
sca and dpa are known as the "achilles heel" ;-)

like how every strength has subtle weakness, so does
encryption, and SCA and DPA are the "achilles heel" of
encryption. xD!

so if i get this device from you? i will be pleased indeed.
and carry on with my research work.

so i will carry with my project anyway. if i dont get it from
you, i will get it from someone else. and i will eventually
break the encryption. its a matter of time. ;-)

hope i am crystal clear and transparent and i did explain
the method well enough.

thanks!

Hello manekari,
greetings!

this is paul. I am extremely eagerly to get my get a grip on this device. why?

I am trying to port coreboot to blackberry playbook.
from crackberry forum i got 3 damaged playbook systemboards.
but i can never get hold of this device be it single piece
or systemboard as such.

i am working on trying to reverse engineer the bootrom.
which is a sha1 sum stored inside the omap4x cpu.

being this a developer edition i will expect it to have a jtag
interface. if it doesnt have a jtag atleast a serial interface.

yes i am well versed with this CPU and i am currently trying to
reverse the hash/key in omap3430 or omap3x which is
found is nokia n900.

i had some serious arguement with crackberry board members,
which is why i am avoiding the forum and slap them back the
decrypted code once i am done. (serious disgust against 
few forum members from crackberry forum)

this device can prove me very valueable insights on the
omap4x which here is omap4470.

i am not a criminal. i am a developer. all i am trying to do is
unlock the FFS locked OS and bootloader and bootrom.

blackberry OS and u-boot (bootloader) and signed bootrom
(x-loader). i think i can reverse engineer the bootrom, and
thus get rid of the FRIGGIN BLACKBERRY crippled handicapped
OS, which turds me to the corner of the dark dimlit room
in the distant galaxy million light year away.

if you or others need to know more let me know. but i will
for sure like to grab this device and start my development
work on omap4470 as well.

hope i will get a decent rate unless you have not sold it
already. the developer editions only got omap4x which
are of interest to me. the production units have qualcomm
which doesnt interest me.

if you still have it, let me know i am interested, i will never
use it but i am 100% sure i will sooner or later be able to
decrypt the private key hash stored in the cpu.

hoping against hope that you still got it and are willing to
sell it at a decent rate.

and once again, i may never use this device, main motive
is to obtain the .pem files which is present inside the CPU.

yes the OMAP4470 stores the signed m-shield x-load
binary key inside the cpu. and the bootloader houses the
validation key which is stored in the emmc nand flash. which
i need to recover since its very important for my project.

thanks!
