Building a better thermostat

I'm setting up an automated temperature control system for brewing beer. My computer is only going to be communicating with heating and cooling elements using on/off control (no ability to set the elements to operate at 50% power, say). I'm hoping there's a better way to control this system than just having a hysteresis range. [more inside]

Can a “linear array” PA system work for a rock band?

I’m tasked with buying a new PA system for a band. I’ve been a working musician for most of my life and have worked with all kinds of sound systems. But I haven’t worked with the new hotness of linear array-style portable PA systems. They seem to have proliferated and I am encountering quite different views of how they work for a *bar-playing rock/country band* situation. If you’ve got experience with this or have been hearing bands work with these systems I’d love some opinions. Details .... [more inside]

I Haven't Played Video Games For Decades. How Do I Start Again?

I haven't played video games since I was a teenager. The games and controls were simple. Super Nintendo, left to right screen layout and a handful of buttons. The games weren't as primitive as Space Invaders, but not as sophisticated as modern games. I want to start gaming again. Where do I start? [more inside]

How to make an easy mailing list for a facebook-centric artist?

I used to employ the RSS-to-email option to give people an easy way to tag tumblr/wordpress posts and convert them into mailings without entering the Mailchimp interface. This doesn't work for people who are facebook or instagram-centric. I have yet to check out Email Beamer and Tinyletter, but I'm wondering if there's any way to more seamlessly integrate a mailing list with facebook somehow, such that post content can be ingested and distributed via email.

Kidnapping, or just camera-shy?

Traveling up in an elevator from the ground floor, I noticed something interesting in only one of the 4 ceiling corners, by the lights. A little before I reached my floor, I snapped a picture of it with my phone, wanting to zoom in later to figure out what it might be. [more inside]
