Hello! I'm cyanic, and I mess around with Japanese toys. This account will mostly be for personal interests. I'll also repost the start of teardown threads here, but if you want to follow the full thread, check @teardowns.caralynx.com.

Seriously though, I had to shovel half a foot of snow in the past couple of days, and the forecast says it's going to go below -33°C today.

Finally got some stuff from Japan shipped. For the longest time Japan Post wasn't shipping to Canada. Anyway, it's another Punitapichan, specifically this year's rerelease. I mainly wanted to see if it's got new firmware.

Writing serialization code is exhausting. I just want to package up some graphics and JSON-formatted data, not have to figure out how to arrange all the bits in a particular way.

Queuing for #39c3 tickets is super competitive. You refresh the instant it the minute hand hits zero and you get queued anywhere from 10 minutes to 60 minutes. I got queued at around 18 minutes, and it sold out with 7 minutes left.

Today's item: LeapFrog LeapMove. I saw this last week at Walmart, and this week after visiting the Lab Tama, I decided I might as well pick it up.

I finally bought something non-Tamagotchi. It's a Bitzee Hamster Ball.

Brush tests from October were bean bodies in mini costumes. They turned out cute. :>

I received a virtual prepaid debit card as a part of a promo, and selected to convert it to plastic. In the meantime, I spent it, and apparently they issued the card after that, because they printed a value of $0.00 on the card. Funniest thing I've seen all day.
A prepaid MasterCard attached to the letter it came on. The card has "0.00" printed in the top right corner (partially obscured by an activation prompt sticker), corresponding to the "0.00" printed near the top of the letter.

I tried to turn on my PowerEdge R630 that has been sitting around turned off for like half a year, and it is no longer turning on. Getting a ton of errors about voltage levels and CPU thermal trip when trying to turn it on. I think it might be a system board issue. Anyone got any ideas?
Screenshot of iDRAC showing errors, including "The system board 3.3V PG voltage is outside of range.", "CPU 2 has a thermal trip (over-temperature) event.", "The system board VCCIO PG voltage is outside of range."

I spent some time figuring out Ciao Plus' image scrambling algorithm because I wanted to archive the Tamagotchi Manga on it. Let's take a look.

I made a mod for @crittercove.bsky.social for loading custom skins. The loading part is easy; next step is to figure out how to export the model and texture from the current body parts selection so people can have a reference to work from.

Apparently Visual Studio has used up my monthly GitHub Copilot quota already and I have literally no idea what it used them for. I didn't make any prompts at all inside VS. Maybe I should just turn the whole thing off again because clearly I don't understand the benefit.

A look at SNC7300 bootrom's UART console. It's... a thing. There's a few pieces to it. You can access ISP features if there is no valid firmware, or if you interrupt boot. By default, the baud rate is 115200, but you can also use auto-baud (I haven't calculated the range).

Continued looking through SNC7330's bootrom, and here's a perplexing piece of code that I reconstructed. It's supposed to return the block (or page?) to read the load table from (basically a bad block table), but I'm pretty sure it doesn't actually work.
Screenshot of C code: uint32_t boot_load_table_offset_from_bb(const uint32_t *tbl) { if ((*tbl & 0xffff) == 0x4242) { uint16_t count = *tbl >> 16; for (int i = 0; i < count; ++i) { uint8_t entry = tbl[i]; for (int j = 0; j < 32; j += 2) { if ((entry >> j & 0x3) == 1) { return i * 4 + j; } } } } return 0; }

Looking through SNC7330's bootrom again. Apparently it's using double precision floating point numbers to calculate the settings for UART speed. WTF? Not to mention that they hardcoded the desired rate and system clock speed, so they could have just precalculated and saved a bunch of cycles.

These were a journey of discovery, but I got there in the end. Lots of experimentation this time. :>
