Raspberry Pi, again. Note, the defect in the Raspberry Pi 2 power supply is particularly interesting. Because the power supply chip has no packaging, flashes of light can cause malfunctioning.

This page is particularly useful for determining the feasibility of taking some digital data interface and transferring it across USB.

The Long Now Foundation? Always use 5-digit years? Really, it it were up to me, I would not be padding out my years to any number of digits if they were shorter or longer than the typical expected length.

Proprietary hardware? This is what you get for hiring an EE or ME. No engineers at these low levels, no new incompatible and nonstandard hardware. That being said, the reason why older electronics tended to feature much more nonstandard hardware configurations is because there was a lot more engineering done at the lower levels for earlier generation electronics.

VERY Helpful Raspberry Pi FAQ. Yeah, I may have jumped too soon on some of my adapters. However, hopes are high for me, I’ve got reports that they will work alright. See my other Raspberry Pi notes for more information.

  • From the FAQ, powering via batteries. “Mobile phone emergency chargers.” Apparently this hints that these devices are capable of accepting AA batteries directly and then converting the current into a steady 5V power supply, which is perhaps the most convenient way to get a power supply for your Raspberry Pi.

Good information on HDMI. Most interesting is Mobile High-definition Link (MHL), a USB form-factor connector that carries HD video. Yes, but although MHL has good prevalence, the main problem is an awareness problem. People are simply unaware that MHL exists and how to use it.

Does the iPad have an HDMI video output? No, but you can buy an adapter for the iPad to get one.

Feasibility of a USB optical disc drive. Overall, yes, a USB 2.0 optical disk drive is feasible. However, it won’t offer the fastest possible data rates for Blu-Ray discs.

Let’s not get the naming wrong. DB-9 is a common misnomer when the correct naming is DE-9. That is, it is a connector with a D-shaped shell of size E and 9 pins on the inside. Nevertheless, DB-9 is a common misnomer.

More information on Super I/O and supported peripherals. All of these peripherals detailed in the article are things that I potentially need to buy an adapter for.

Seriously, I’ve got to figure out what that infrared port is on the back of the ProGen computer.
