Very sorry for the confusion. [Digi-Key is a proud sponsor of the 2022 Hackaday Prize]( [3602421454791242043.png] Wednesday, October 12, 2022 [Interactive Air Quality Map Lets You Breathe Easy »]( (No More) Time To Get Wild We're extremely sorry for the confusion! Our wires got crossed, and we forgot about the change in the end date for the Wildcard Round. The official rules on [the Prize webpage]( are correct. The round closed last Sunday, and our judges are already at work to see who goes on to the final round. Again, our sincerest apologies for the confusion. Highlights from the IO

[Ethersweep: Monitor and Control All the Motors]( Need easy interfacing between things like computers and machines to motion controllers? It doesn't get much easier than bolting these double-decker delights directly to your NEMA-17s. [project thumbnail](
[Look Ma, No Microcontroller!]( While this portable spot welder may look smart, there isn't a microcontroller in sight, just a bunch of hard-working electrolytic capacitors. The ability to discharge makes it safe to store, and (relatively) safe to use. [project thumbnail](
[Adding Fun-ctionality to Wheelchairs]( If you use a power wheelchair, you're likely to be familiar with the controller already, so why not use it for games, too? JoytoJoy is a simple add-on joystick that revs up the fun by adding an easy-to-use game controller right on top of the chair's joystick. Hack Chat
LIVE CHAT WITH LEADING EXPERTS EVERY WEDNESDAY [Today: RF Hacking Hack Chat]( Join us today at noon Pacific for the [RF Hacking Hack Chat]( with Chris Poore! For as revolutionary as cheap SDRs have been, hacking in the RF realm can sometimes be a bit difficult. To pull off really righteous hacks, you need some kind of framework that lets you build some context around the signals you pull out of the ether. Chris Poore will drop by the Hack Chat to talk about one such framework, called FISSURE, and about RF hacking and reverse engineering in general. Check it out and bring your questions and war stories to share. [Next Week: Lubrication Engineering Hack Chat]( Rafe Britton will host [next week's Hack Chat](. It may seem like WD-40 is the answer to everything, but there's much more to lubrication than just a spritz from the familiar blue and yellow can. Modern lubricants are extremely complex substances that are highly engineered to have specific properties under specific conditions. And while you might not need to know the details of how lubricants are made, getting a little inside information on them from a professional lubrication engineer can help you make better decisions on which oils and greases are right for your application. Rafe Britton will stop by the Hack Chat to talk about all the engineering that goes into that liter of oil or tube of grease, and how to put them to work. Featured Projects
