"Palette" chain, featuring slides, a dial, and buttons. Looks like a DJ's dream. (via kickstarter) Kickstarter brings us chainable devices that are poised to change the way computers are used - and it is a throwback to simpler ways. Personal computers have changed the way business is done around the world, and while the functionality of a personal computer is broad, Calvin Chu and Ashish Bidadi believe the usability of personal computers leaves a lot to be desired. That’s why they dev ...
Introduction This post is about building a frequency synthesiser for various uses such as for a home lab or as a module for a larger project. The implementation can be useful from a few tens of kHz up to 160MHz; not anywhere near the capabilities of a commercial signal generator, but still very usable. It primarily generates sine waves and square waves but can also handle some forms of modulation and controlled sweeps. This should cover many use-cases, particularly radio related. So far, single ...
Thermal cameras can be a huge help around the electronics lab. With the ability to instantly visualize the many different temperatures of an area, there are applications beyond the obvious heat sink performance characterization. An engineer can use them when troubleshooting a board, to understand sensitive circuits, calculate junction temperatures, and work through power consumption issues. In the past these tools have been very expensive, on the order of $20 – 30k, such as the instrument- ...
The Agilent 34461A provides many different connectivity options, USB, LAN and GPIB (as an optional extra), which means that it should easily fit into a modern lab or test system. For test systems, it is likely that custom software will be written to control the entire system, however, for a lab this is often not the case, relying on the manufacturers software. Agilent provide two connectivity utilities to do this, the first is meant for Windows computers and the second is meant for the Apple iPa ...
