Did you know there were typewriters that used ball point pens to draw not just text but also graphics? I’ve collected several of these over the years. Read on to discover a world that you didn’t know existed.

Modern TVs are very poorly suited for kids. They require using complicated remotes or mobile phones, and navigating apps that continually try to lure you into watching something else than you intended to. The usual scenario ends up with the kid feeling disempowered and asking an adult to put something on. That something ends up on auto-play because then the adult is free to do other things and the kid ends up stranded powerless and comatose in front of the TV.

Sometimes it’s handy to have a repeater to extend the range of a radio transmission. The particular usage I have in mind is to be able to receive telemetry from a landed payload that is too far away (or hidden by buildings or geography) to receive directly, but could possibly be received via a repeater up on a mast or flying on a drone.

The South Philly sign was not installed by the Southeastern Pennsylvania Transportation Authority. Instead, it is one of several signs placed by local street artists who program digital screens, charge them with solar-powered batteries and carefully examine the ins and outs of sign design.
