Intro & Parts List This tutorial was designed to help you build an in-car infotainment system or carputer using a Raspberry Pi, and a few other components. The concept was something that I found when I got my first Raspberry Pi for a class, and was exploring some of the things that could be done …
It’s easy to get caught up in a build and forget that the final version usually needs some sort of enclosure, especially things with sensitive electronics in them. The [Director of Legal Evil] at the LVL1 Louisville Hackerspace notes as much in his recent radio build. It seems as though the case was indeed an …
The Project Horus team routinely launches high-altitude balloons in Australia. However, despite their desire for it, they haven’t beamed back live video. Until now. Horus 55 beamed video back to the ground from over 100,000 feet using a Raspberry Pi and some software-defined radio gear. Be sure and check out their video, below. You might think this …

With digital semiconductor technology driving system power supplies to lower voltages for higher performance and lower system power, sensitive analog sensor circuits face a growing problem. Much of the inherent noise created in the early stages of an analog sensor signal path is independent of the amplifier bias voltage, so using a higher bias voltage …
USB powered mini speaker amplifier is conveniently powered by USB and it is simple to set up. USB powered speakers are convenient for listening to your media while at home or on the go. Conventional computer speakers that require an electrical outlet to work can be prohibitive because they force you to be close to …
u-blox, a global provider of leading positioning and wireless communication technologies, has announced its new ultra-robust meter-level M9 global positioning technology platform, designed for demanding automotive, telematics, and UAV applications. Thanks to its high performance GNSS chip, UBX-M9140, the M9 technology platform and the NEO-M9N, the first module based on the platform, can receive signals from up …
I have always wanted to build a fairly capable LCR meter that could cope with real world use in my own personal lab. This would mean reasonably good accuracy across a wide range of L, C and R. Fortunately, I got the time to do just that this year in the 3rd year Instrumentation module …
Accurately detects heat to identify types of heat sources and specific human behavior Mitsubishi Electric Corporation announced that it will launch the Mitsubishi Electric Diode InfraRed sensor (MelDIR), a thermal sensor for applications in the fields of security, heating, ventilation and air conditioning (HVAC) and smart buildings, on November 1. MelDIR accurately distinguishes between humans and …

I’ve always wanted to know what the “tube magic” was all about. There is much opinion in the science of music production, probably because music and its perception is highly personal and subjective. Ive always imagined that since transistor amplifiers were “perfect” with their large amounts of negative feedback, great linearity, and low THD that …
IBASE Technology Inc., a world leading supplier of embedded board and industrial computing systems, has released the IB822 3.5-inch SBC (single board computer) supporting Intel’s “Gemini Lake” Pentium® Silver J5005 and Celeron® J4005 processors built with 14nm fabrication, a base clock/burst rate of 1.5GHz/2.8GHz and 2.0GHz/2.7GHz, and integrated Intel® UHD Graphics 605 (18EUs@800MHz) and UHD …
