[Hackaday] Conventional Current Vs. Electron Current [Read article now »]( The Last Minute By [Elliot Williams]( We've always held that the last minute is the sweetest minute. Although every minute you spend on a project contains exactly sixty seconds, most other minutes pass by unheralded.

The artwork is nothing short of fantastic, and if these things fly (tee-hee), it'll be a great hack. Finally, [Garrett] came out with an ESP8266-based badge that [takes advantage of the WiFi chip's extra functionality.](. Besides blinking, this badge functions as an AP scanner, packet monitor, and deauth-packet detector. It's a hacker badge that's a useful hacker tool. Hack Chat [AnnMarie Thomas] is in the [Hack Chat this week]( and she is going to tell us a thing or two about making electronics for education. If you've ever wanted to share the joy of hacking with others, you've probably thought about making a small bot, a kit, or even just an educational toy. [AnnMarie] is an expert in the intersection of technology, education, and converting ideas into products. [Join us]( in the discussion!
