[CreativeLab] purchased an inexpensive arbitrary waveform generator and famous that it solely had a two-pin energy twine. That has its ups and downs. We really feel sure the intent was to isolate the interior switching energy provide to stop floor loops via the scope probes or the USB connector. Nevertheless, it’s good to have all of your gear referencing the identical floor. [CreativeLab] agrees, so he determined to do one thing about it.
Opening the field revealed that there was hardly something inside. The principle board was behind the entrance panel. There was additionally the ability provide and a USB board. Plus a lot of empty house. Some argue the case is made too massive to be misleading, however we desire to suppose it was to present you a beneficiant entrance panel to make use of. Possibly.
It was a easy matter to floor all the pieces to a brand new three-pin connector, however that left the issue of the USB port. Fortunately, because it was already out by itself board, it was straightforward to wire in an isolator.
Truthfully? We’d have hesitated to do that except we had made completely positive it didn’t pose some security hazard to “leap over” the switching energy provide. They’re usually remoted for some purpose. Nevertheless, the chances are it’s simply tremendous. What do you suppose? Tell us within the feedback.
An identical unit had a reverse engineering venture featured on Hackaday a few years in the past. Whereas these was unique gear, when you don’t thoughts some limitations, it is rather straightforward to roll your personal lately.
