Re: Stuffs to read before going to bed
I thought I posted this a while ago but I guess I didn't: 10 Ways to Destroy an Arduino http://ruggedcircuits.com/html/ancp01.html It's about all the different ways a circuit can be destroyed (in this case an Arduino), and how protection measures can be added. In terms of making a more robust/safe p...

Re: Stuffs to read before going to bed
Here's the transcript of Michael Barr testifying about his analysis of the firmware in Toyota's engine control unit: http://www.safetyresearch.net/Library/Bookout_v_Toyota_Barr_REDACTED.pdf The gist of it is that too many tasks could be running at once, causing a stack overflow that would lead to sy...

Re: Stuffs to read before going to bed
This guy made a battery charger using the LM317 which is a adjustable voltage regulator. http://www.dinamousers.net/tiki-index.php?page=Battery+Charger What's cool is that he used a binary weighted ladder controlled by a DIP switch to control the adjustment, instead of using a regular potentiometer....

Re: Stuffs to read before going to bed
Here's a good article about how voltage at an I/O pin of an unpowered chip can find a path to the supply rail through ESD protection diodes: http://www.analog.com/library/analogDialogue/archives/42-10/off_amps.html I have an interesting real-world example to add to this: The Sega Saturn Action Repla...

Re: [Translation] Nazo no Masquerade
Awesome! Sounds like serious progress.
Will all the tools and stuff for this project be released like they were with Marchen Maze?

Re: Stuffs to read before going to bed
This page links to a PDF transcript of a discussion with the Motorola 68000 design team: http://www.computerhistory.org/collections/accession/102658164 There's a lot of cool stuff in here, like all 680x0 circuitry was tested on breadboards until the 68040, at which point they finally started to simu...

Re: [ASM] Tips and tricks
Accessing quantities larger than 8 bits can be problematic on the HuC6280. Normally you have to do something like this to get a 16-bit word from a table: lda <index asl a tax lda table+0, x sta <lowByte lda table+1, x sta <highByte ; table: .dw $1234 .dw $5678 Here, 'index' is limited to 0-127 which...

Re: Stuffs to read before going to bed
This is the homepage of Ryuichi Takahashi, one of the designers of the NEC V60 CPU: http://homepage3.nifty.com/alpha-1/index.html He describes his time at NEC amongst other things, and has a lot of insight about microprocessor design. Almost everything is in English, though the sections are quite sm...

I wish there were more PS/PS2 developers willing to discuss their methods, it's fascinating stuff.
