RC Network Eliminates Precision Reference - 08/04/94 EDN-Design Ideas The circuit in Fig 1 uses a magneto-resistive sensor to detect small magnet displacements without resorting to a precision voltage reference. A simple RC divider takes the place of the reference, eliminating an expensive component__ Circuit Design by Christophe Basso, European Synchrotron Radiation Facility, Grenoble, France
Resolve 0.1-Ff Change from 100 Pf - 01/06/00 EDN-Design Ideas The circuit in Figure 1 can resolve 0.1-fF changes in a 100-pF bridge element and can accommodate large-scale changes in the bridge without adjustment. You can use changes in capacitance to measure applied pressure, rotation, torque, liquid level, the wat__ Circuit Design by Derek Redmayne
Reversing H-bridge - This H-bridge variant was one of the first in which the reversing circuitry is built into the driver, rather than (as is more-commonly done) into the control circuitry upstream of the driver. This is a handy circuit, though, for 2-motor walkers -- as all that is required to reverse one is to reverse the phasing of one of the motors. It is built from 4 transistors and a mux. __ Designed by Wilf Rigter

Soldering iron driver bridge controls temperature - 09/06/13 EDN-Design Ideas With a power supply and a replacement soldering handle you can implement this temperature-controlled soldering iron driver. One way you can control the temperature of a soldering iron is with a microcontroller, using temperature feedback from the thermistor in the handle near the iron's tip. This Design Idea presents a soldering iron driver that does this using only analog components. __ Circuit Design by Kiril Karagiozov

Wattmeter - The extra input B is for a later SWR brigde project, also the TX serial output will be in use later. The uncalibrated signal response is: +1/-1 dB from 1MHz to 450MHz. Input SWR vill varry from 1.00 to 1.30, depending on input frequency. To make the SWR this good, you need to assemble the input circuit correct and adjust the capasitor. Input power range: -60 to +30dBm that is 1 nW to 1 Watt. __
