April brought another great meeting! Thanks again for the Milwaukee Makerspace for hosting us. Klaiviel taught us quite a few things about locks, he had his collection out for display.

We then toured the facility again, always a great time to explore the Makerspace! We were able to see this crazy subwoofer in action!

It’s a booth you sit inside and /FEEL THE G’s/ Here’s Vlad inside:

We had to tone it down after threats of the police being called for noise were voiced. 🙂

After that, we went back and saw a cool piece of machinery that Mike put together, cooling a computer and GPU with a dehumidifier!

We then spent the better part of the evening debating the merits of salted butter, vs unsalted butter. Seems Faraday really has a strong opinion about it! here’s this… equation that lays it all out for us:

All in all, another great meeting. See you next month at the Meetupery!

March came in, and was an awesome time. Too bad ngharo and vlad missed it. We were hopping at the Meetupery!

dw5304 got things started with some radio hacking, with his HackerRF board that he’s managed to un-brick. We swept some bands, and learned that car FOBs generally work around 300mhz for sending signals. And Chrysler FOBs have some good output!

After that, we had some fun with a giant lock that Klaviel tried his hand at. This thing is used for some serious security!

We also reminisced about previous dc414 meetings, like a certain laser incident, and RF jammers. W also got to see a neat piece of hackery, an ammo can turned into a self contained power supply, with lithium drill batteries and an inverter. Awesomesauce!

Thanks for everyone who came out, and we’ll see you again next month!
