"Mr. Hat contacted me asking for a help in building a phono preamp for his vinyl record player that he recovered from oblivion somewhere. As you probably know, there are some issues with vinyl records that require audio tracks to be mastered in certain way before they are put into a disc."

"Designed and built during October 2000, this was my first ever microcontroller based project. This one was inspired by an Edmund Scientific instruments catalog. I didn’t see anything like this in that catalog but there were a lot of nice, year 2000 modern multipole cable testers, that made me think and imagine what would be the simplest possible network cable tester that I could quickly build."

"Behold: a complete Nintendo Entertainment System cloned in an FPGA! Originally written in VHDL by Brent Allen and myself while at Washington State University, I’ve recently revisited this project and begun both: rewriting it in Verilog, and adding many new features."

"This is a simple JTAG interface, which can be connected to computer’s parallel port. It is originally designed by Xilinx to program FPGAs and CPLDs… It is a one-sided PCB, the bottom side is made from wires."

"One field of communication and DSP that has always intrigued me is signal intelligence, the attempt to receive and decode an unknown signal. It’s an interesting puzzle that requires a wide variety of hardware, software, and analytical skills…I decided I would try to receive and decode the signal my garage door remote transmits to the base unit to open and close the door."

Are you ready to say Hello World? Today we’re releasing the second lesson in our new course: An Introduction To Microcontrollers is live. Here’s an overview of the lesson:

"Building a ‘hello world’ application signifies a time honored approach to learning how to program. In this lesson, we will explore the first steps necessary for building and loading programs onto a microcontroller."

"The DIY pick and place machine project is now finally running and is able to place the components for our Raspberry Pi expansion boards. This project started in July 2013 when we began to order the various components, bearings, motors, drive systems, frame materials etc and we started to build the machine in September."

"The objective is to use readily available ‘off-the-shelf’ low-cost consumer components where possible, and to design electronic subsystems where such components are either not readily available or are too expensive. In terms of affordability, the overall goal is to design a robot that can be made for around the price of a PC."

"Jonathan Ward from the MIT Center for Bits and Atoms has designed a snap-together, desktop-sized CNC milling machine. The MTM Snap is made from 1/2-inch high-density polyethylene (HDPE) – itself milled on a ShopBot – and can be assembled for about $700. This three-axis CNC machine can mill circuit boards, wax molds, and harder materials in a 5x3x1.75″ working area. "
