Whitehat Wednesday is back – Intro to x86 Assembly

We are bringing back Whitehat Wednesdays! Our first class/workshop will go over the basics of Assembly language. When: Wednesday, December 23 – 7:30pm-9:30pm Class Prerequisites: Must have a basic understanding of the C programming language, as this class will show how C code corresponds to assembly code. Lab Requirements: Requires a Linux system (recommend Kali) with gcc and gdb   This class serves as a foundation x86 assembly language. It teaches the basic concepts and describes the hardware that assembly code deals with. It also goes Read More +

FAA Now Requires Model Aircraft Registration

The FAA has mandated anyone operating model aircraft over 250 grams to register. It’s one registration number that’s used across your vehicles. This does apply to traditional fixed and rotary wing model aircraft. If you don’t want to pay the fee, it’s refundable for a period. “The normal registration fee is $5, but in an effort to encourage as many people as possible to register quickly, the FAA is waiving this fee for the first 30 days (from Dec. 21, 2015 to Jan 20, 2016).” It’s Read More +

Pi Zero

Today we received our first Pi Zero, Priced at just $5, we were lucky to get one the 100 orders available from Adafruit at 2am on Thanksgiving morning. Now just to figure out what project we are going to utilize this in Pi Zero features: A Broadcom BCM2835 application processor 1GHz ARM11 core (40% faster than Raspberry Pi 1) 512MB of LPDDR2 SDRAM A micro-SD card slot A mini-HDMI socket for 1080p60 video output Micro-USB sockets for data and power An unpopulated 40-pin GPIO header Read More +

SawStop – New Tool

Earlier this year we had a successful fundraiser for a new SawStop. We chose the saw for safety reasons, the saw blade carries a small electrical signal, which the safety system continually monitors. When skin contacts the blade, the signal changes because the human body is conductive, this causes the blade to drop and fall so the user is not harmed. All this happens in less than 5 milliseconds! We spent the last week putting it together and testing. Last night member Katie taught the Read More +

Electric Spinner

One of our members Andrew built his wife an electric spinning wheel for Christmas this year utilizing the laser cutter and woodworking tools at NESIT. Check out the details on how he built it ::here:: on his site. Be sure to check the other awesome projects he has built there too.

Casting Aluminum with Mini-Foundry

The goal for our casting experiment is to expand the number of materials our space is capable of working with and creating more durable parts. And at a price of under $20 , this project was perfect. Charcoal foundries can reach temperatures in excess of 1,000ºC which is plenty for us to melt aluminum. It’s melting point is only 660.3°C Roughly following the instructions from the King of Random, we created a form consisting of two plastic buckets and pouring in conventional quick-drying cement.
