In this strangely fascinating talk, you can follow along as [Natalie Silvanovich] reverse engineers some tomogotchi. Even if you have no interest whatsoever in tomogotchi, you’ll probably pick up a trick or two by listening to how she went about taking over the toy. She can now push her own images to the screen, and evolve her tomogatchi at will.
Listening to her story you might be able to pick up a few tricks as she takes almost every angle possible. She uncovers the black blobs, she attempts to socially engineer her way into datasheets, decaps chips, she dumps and breaks down code. It is also worth noting that, in the beginning, internet electronics enthusiasts were adamant that it just had a PIC processor inside and they were wrong. Having an internet full of experts is a wonderful thing, except when it isn’t.
Then again, having that internet full of experts might be her savior in the end, she’s missing a piece of software and asking if anyone has it available.
Cool! Why don’t they put this stuff on youtube?
Feel free to put it there. ccc relies preferably on own infrastructure.
Thank you for posting this. A lot of people tweeted that it was one of the better talks, but then I couldn’t find it anywhere.
I wonder if she’s willing to share the data she managed to pull of the chips. Sounds like it’d be a trivial thing to get up and running in MESS.
at the end she says something about it all being on github.
Doesn’t she say that the actual code haven’t been dumped?
on github are the hacking tools.
I love how there’s a lot of armchair hackers… ooops, morons that insist that every microcontroller based device out there uses an AVR, PIC or more recently, ARM. It’s like those morons can’t conceptualize the idea that a 6502, or any other architecture for that matter, can actually be a microcontroller core.
I guess it’s a second generation of Internet Experts. The first one grew up with PICs being synonymous with microcontrollers. The current one does not even know much about microcontrollers but remembers some PICs.
Don’t know what generation number I’m in, but circa early 90’s I grew up desoldering IC’s from matrix printers, vcr’s and anything with a hint of digital to salvage whatever looked like a controller or RAM/EEPROM. Then off to the library with a list of numbers to photocopy the specs from the dead tree catalogues. Most of us (we had a club) were programming without knowing the controller family – the serial numbers were often variations with long suffixes.
Yeap, PICs aren’t even that price efficient for jobs like that.
Isn’t that where everyone hacks from? Their armchair.
My pet peeve is EE types that don’t know much about OS design, network integration or much anything bigger than a microcontroller yet claim they know all about computers, servers, and networks. It’s like a dentist deciding he is an expert on knee replacement surgery.
It’s always 6502!
You’re very mistaken. It’s a z80.
It’s not. Where did you listen it was a Z80?
EVERYTHING is a Z80.
For the longest time, I was given to believe that PIC was Programmable Integrated Circuit, which would make it synonymous with microcontroller. 
Still waiting for someone to hack a way to reset single use temperature loggers.
In the talk she mentions that there are high resolution die photographs on her blog. I could not find any at http://www.kwartzlab.ca/author/natalies/. Any pointers?
Other than suspected in the talk, the mask version of the chip still has the test interface present: The datasheet lists a test input pin and in the memory layout, there is a “test program area” and a “test interrupt vector”! I would guess that toggling that pin (or holding+reset) will execute a test program.
The only challenge might be that the test pin is not accessible on the pcb or it might not be bonded to the pcb (high resolution photographs!). It you are lucky, the epoxy removal process could leave the chips working tough!
Wish the pictures were a better, but it gives an better idea of the IC at least.. I’d like to decap them on my own but I have neither the nitric acid nor the necessary microscope.. Being able to “dump” the mask ROM right from the chip itself would be a dream.
The link is dead. https://www.youtube.com/watch?v=KxeA33yhm7o seems to be the same thing the original one was.What IP addresses does Abaciscus.xyz resolve to?

French doom metal masters Monolithe unveiled some fresh news, regarding the upcoming effort. Their eighth full length album, the follow-up to 2018' Nebula Septem, is almost completely written. The band has planned to hit the studio in 2019 for a tentative early 2020 release. More news to follow.
Nebula Septem was released back in January 26th, 2018 through Les Acteurs De l'ombre (LADLO) Productions. It was the first full length product, released by LADLO.
Joint Wireless Fronthaul and OFDMA Resource Allocation in Ultra-Dense CRAN

Ultra-dense (UD) wireless networks and cloud radio access networks (CRAN) are two promising network architectures for the emerging 5G wireless communication systems. By jointly employing UD network with CRAN, a new appealing network solution is proposed, termed UD-CRAN, which can achieve ultra-high-throughput wireless connectivity. In UD-CRAN, a wireless fronthaul is practically favorable to connect a central processor (CP) with distributed remote radio heads (RRHs), due to its lower cost and higher flexibility to deploy. As the wireless fronthaul capacity is limited, it motivates considering the downlink transmission in a UD-CRAN where the wireless fronthaul is shared among the RRHs via time division multiple access~(TDMA), while the RRHs jointly transmit to the users via orthogonal frequency division multiple access (OFDMA). The joint resource allocation over the TDMA-based wireless fronthaul and OFDMA-based wireless transmission is investigated to maximize the weighted sum rate of all users. Although the problem is combinatorial and non-convex, we propose a Lagrange duality based solution, which can be efficiently computed with good accuracy. To further reduce the complexity, we also propose a greedy search based heuristic, which achieves close to optimal performance under practical setups. Finally, we compare the performance of proposed solutions with other benchmark schemes by simulations, which show significant throughput gains of the proposed joint resource allocation approach.VRay Render, If you’re tired of waiting on the display screen for lengthy hours ready for the subsequent pixel to look, you have the choice of building your individual render farm. The perfect factor about building your individual render farm is that it’s a reasonably priced and quick course. When you intend to render scenes with VRay, you actually need to have quick processors. The excellent news is that development in expertise has made it attainable so that you can render your scenes quickly. Nevertheless, earlier than taking a look at how one can construct your individual VRay farm, it’s important that you simply perceive what is supposed by VRay.
VRay is a software program that’s principally utilized by render farms. This can be very straightforward to arrange and has an inbuilt community rendering possibility. Earlier than establishing your VRay render farm, there is a selection of issues that you simply may want.
– The very first thing you will have is to have VRay put in your computer systems. Important to notice is that there isn’t any standalone model of VRay, so it must be put in with Maya or Max amongst others.
– Additionally, you will want a neighborhood community of computer systems with entry to one another. It is important that the computer systems are all linked and that they’re a part of the identical community. As well as, the connection shouldn’t be blocked or interrupted by firewalls.
– It is important that you’ve got entry to a quick community. It isn’t acceptable so that you can have a gradual community or wi-fi connections. Additionally, it is not really helpful that you simply use Wi-
