PORTLAND, Ore. — Today we have superconductors levitating trains for high-speed transportation, superconductors wired as ultra-sensitive sensors for MRI (magnetic resonance imaging) and superconducting coils powering ultra-strong electromagnets for beam steering in particle accelerators. However, if a room-temperature version of these superconductors — which today have to be ultra-cooled — could be found, then they […]

The USB keypad reference design demonstrates crystal free USB operation. Microchip has partnered with Lumvatech to demonstrate a low-cost aesthetic design, with touch capability and LED lighting integrated. All features are driven with a single PIC16F1459 MCU. USB is one of the most common serial interfaces used in a wide variety of applications. The USB […]

When I saw the Aurora LED 9×18 Instructable, I was inspired.  However, it’s built on the PIC microcontroller while I am most familiar with the AVR microcontrollers.  Plus, I already have the development and programming environments for AVRs, so I set about a redesign as a personal challenge.  I wanted to make something (almost) just […]

Running NodeMCU on a battery: ESP8266 low power consumption revisited Over the last year I have standardised on the ESP8266 for all my small IoT projects. Its low price, ease of use (now that the Arduino IDE is available), tiny size and built in Wi-Fi makes it a compelling option. Using Wi-Fi is a convenient way to link […]

Professionals, school laboratories and amateurs can now gain this new, extra affordable digital MSO oscilloscope in a limited offer. Probably you may have noticed, that company Hameg became a member of Rohde&Schwarz group and new oscilloscopes already carry only an R&S logo. However the name of series HMO remains, which represents for several years products […]

Preparation In addition to the power supply that you created on your breadboard in Lab 2, you will need the following equipment/components to complete your PIC prototype board: (1) multimeter (1) PIC 24HJ32GP202 chip (2) alligator clip leads (1) LED (1) 1K Ohm resistor (1) 2 K or 2.2 K Ohm resistor (1) 10 micro […]

The first question I often get about this creation is “Why?.” The answer is quite simple, I am an engineering student at Stony Brook University. We play a game on campus called “Humans vs. Zombies.” That fact coupled with my over competitiveness, and my drive to engineer things most people wouldn’t is what ultimately spawned […]

Week 01 January 11, 2012 (1 hour): Met with professor Talavage to discuss the basic functionality of the headset sensor devices that will be used to collect data for this project. Discussed challenges of interfacing these devices to the base station using the USB protocol standard. January 11, 2012 (1 hour): Met as a team […]

Many homes in the United States have water that contains higher concentrations of dissolved minerals, which is called hard water. Although there is nothing toxic about hard water, it is less desirable for cleaning, it leaves mineral deposits, and it can shorten the lifetime or efficiency of equipment such as water heaters. A water softener […]

Ok, so there are heaps of immobilisers out there but with most of them, if someone has your keys, they have you car.  What good is a car alarm with 3+ point immobilisation if someone manages to get the keys and of course the alarm remote. This is a simple immobiliser based on a PIC12F629 and […]
