It’s probably not much of a stretch to say that many of us have taken on a project or two that were little more than thinly veiled excuses to add a new tool or piece of gear to our arsenal. There’s ...

It’s always a pleasure to find a hardware hacker who you haven’t seen before, and page back through their work. [Bettina Neumryr]’s niche comes in building projects from old electronics magazines, and ...

Unlike digital RF generators that produce only sine waves, function generators can produce repetitive waveforms of different shapes such as sine, square, triangular, sawtooth, and pulse. Function ...

The possibility of creating a frequency-tunable function generator with rectangular and triangular pulses of constant amplitude and electronic synchronous control of equivalent capacitances in the ...

Commercial curve tracers have existed for decades. But designers without access to one can create a simple circuit that uses a function generator and oscilloscope to generate JFET transfer and ...

A former coworker friend sent me a Tektronix 3-slot mainframe and several plug-in modules (Fig. 1). The TM500-series mainframes are 1970s vintage, but like a lot of old test equipment, can still work ...

Wind Engineering, Vol. 12, No. 6 (1988), pp. 333-340 (8 pages) A slip-ring induction machine with power-electronic control of slip-energy can provide a cost effective variable-speed generator for ...
