I'm building a SCPI shell for Linux. I have the basis working over TCP/IP on a Raspberry Pi and a BeagleBone.   In this post I'll show the basics: the Pi or BB listens to SCPI commands and sends replies. I'll include the LabVIEW test bed that I used to get this working.     In this series, I'm focusing on the specifics for TCP/IP communication with a SCPI service. I will not make an instrument but this project can serve as the basis of a SCPI programmable Linux device.  ...
Disney’s research team is pushing augmented and virtual reality to the next level with a jacket that let the wearer immerse his senses into whatever game he is playing.

One such company i ...
Analog Time ! I've prepared the DC Load to measure the behaviour of the circuit. In this blog series I'll show dynamic aspects of the instrument. The first blog shows the points of interest and some initial teaser measurements. If you want a particular measurement to be done, ask in the comments.     Test Points  I've wired the main points of the control circuit - an opamp integrator: the inputs of the integrator (set point and measured feedback) the output of the integra ...
A newly designed driverless car called Roborace will make a new spin on wheels, and it isn't something ordinary, either because the vehicle isn't operated with a human driver behind the wheels. It's completely AI-controlled. The leaders behind Roborace hired Daniel Simon to do some navigating in designing the car. Simon is also responsible for designing the vehicles in Tron: Legacy, Oblivion's drones and spaceships and Captain America's hydra vehicles.   Since Roborace is influenced and g ...
I recently received a new oscilloscope, the Keysight DSO1102G, for my workbench. I’ve had the Tektronix TBS1202B-EDU on my desk for a long while. Having never read through its manual I thought now would be a good time do a thorough read of both manuals. This would give me a better and more complete understanding of these two oscilloscopes. It would also allow me to have a greater appreciation of the differences between the two oscilloscopes without missing anything.   Out of the box ...
Introduction This short blog post explores the difference between home-made, low-cost, a mid-cost and a high end 50 ohm load! They have many uses. The larger ones are often used to test transmitters, such as for Ham radio or Citizens' Band (CB) radio.   I used the Rohde & Schwarz FPC1500 Spectrum Analyzer in its Vector Network Analyzer (VNA) mode to examine them. There is more detail about the FPC1500 and how vector network analysis is used in the FPC1500 review here.   What ...
Insight lander offers an enhanced vision of Mars beneath the surface. The mission will take 6+ months to complete. Pictured, an artist's concept of InSight with its instruments on Mars. (Photo Credit: JPL-CALTECH/NASA)   A new mission to Mars hopes to expand and enhance our understanding of the red planet's internal structure. On Saturday, NASA had launched a robotic instrument with a hammer and quake monitor. However, the journey had a different approach - one that launched for the first ...

Soldering Irons

Posted by fluxcap May 4, 2018
I'm looking to step up my soldering game. I've seen the relatively new intergrated heating element into the soldering iron tip, like the JBC stations. Does anyone know a budget version that uses the same tech? ...
A San Francisco based technology firm, Osterhout Design Group released the prototype for a new smart glass that will allow aircrafts pilots to land safely in case of emergency when the cockpit is filled with smoke.
