Painfully Obvious.

Let’s make the poor‐man’s version of LEDBlinky: a way to light up specific buttons for specific games using a Pac‐Drive and some shell scripts.

How to wire up a hardware knob that controls the Pi’s software volume level via GPIO.

I wanted an easy way to power the system on or off without going through a menu. I managed to do it with a hardware add‐on and a simple Python script.

All the stuff I wish I’d known about RetroPie and MAME that wasn’t written down in one specific place.

Before your attention flags, I want to wrap up the hardware portion of this series and move into the software. But first I need to cover some odds and ends.

Last time I told you a story of how I built an arcade cabinet out of a couple sheets of MDF. The part I left out was the making of the control panel — the MDF board that will hold the buttons, joysticks, and other controls.

In part one of a too‐many‐parted series, learn how I turned a couple of sheets of MDF into an arcade cabinet with several pounds of sawdust as by‐product.

I don’t have the patience to learn new skills for their own sake. Most of what I know about computers, including everything I do at my day job, was something I learned because I needed it to do something cool. In 2001 I needed to learn PHP to make a…

Last time, I treated you guys to some Solomonesque baby‐splitting between Steve Klabnik and DHH, and then spent two dozen paragraphs talking about how Gowalla’s API was pretty groundbreaking and how Scott Raymond was like the Lou Reed of hypermedia APIs. To balance out all this ridiculous self‐praise, I’ll talk…

Before I convince myself it’s a bad idea, let’s take a retrospective look at the Gowalla API (which, by the way, was started in 2008–2009) and see how it measures up against a hypermedia rubric.
