Given the low costs and extensive applications that could be possible with flexible paper circuit boards, we've seen many ideas for their production, from printing with silver ink to embedding chips ...

Engineers at FPGA manufacturer Xilinx had a measurement challenge: how to characterize the 28Gb/s serial links in their devices. At such a data rate, even very short connections can cause signal ...

Building electric circuits has been a science-class staple for decades. Using copper wire, a 9-volt battery and a light bulb, students learn about the flow of electricity. That classic lesson is ...

Most of us can do simple math in our heads, but some people just can’t seem to add two numbers between 0 and 3 without using paper, like [Aliaksei Zholner] does with his fluidic adder circuit built ...

As the number of Power Over Ethernet (PoE) powered device (PD) applications grows, market pressures are driving designers to lower the cost and complexity of the DC-DC converters that power them, ...
