Circuit for measuring motor speed uses low-cost components -  8-Nov-07 Issue of EDN  A microcontroller-based circuit provides both an LCD readout and an analog motor-speed output....[Design Idea by R García-Gil, J Castelló, and JM Espí, Escola Tècnica Superior d’Enginyeria, University of Valencia, Spain]
Circuit for Soft-Start Module -  Simple circuit that reduces surge current on start of an induction motor.  ….(electronic schematic added 06/09)
Circuit Monitor 2 -  This is a circuit monitoring device. It runs for over 10 days and can log up to 32k events both digital and analog. Samples are logged either on a timing basis (.01 to 2.5 seconds), or on a triggered basis. Four inputs are provided, up to three of which can be analog....[Luhan Monat - Mesa Arizona]
Circuit programs Atmel AVR µCs -  30-Mar-00 Issue of EDN  Atmel AVR mCs feature an enhanced RISC architecture that purportedly offer the highest MIPS-per-milliwatt capability in the 8-bit mC market. Figure 1 shows an easy-to-build ...[Design Idea by Guo-Yin Xu, XuMicro, Houston, TX]

Circuit Programs Atmel AVR microControllers -  03/30/00 EDN-Design Ideas EDN is migrating links. This link is not verified.  Search the "title" + "EDN" for new link.
Circuit provides 4  to 20 mA loop for microcontrollers -  27-May-04 Issue of EDN  The 4- to 20-mA current loop is ubiquitous in the world of controls in manufacturing plants. Discrete logic, microprocessors, and microcontrollers easily cover the digital portions of control schemes, such as limit switches, pushbuttons, and signal lights. Interfacing a 4- to 20-mA output to a rudimentary microcontroller can be problematic....[Design Idea by Robert Most, Dow Corning Corp, Auburn, MI]

Circuit provides watchdog for microcontrollers -  26-Dec-02 Issue of EDN  The watchdog circuit in Figure 1 uses a single NAND Schmitt-trigger IC. The circuit iscost-effective than dedicated, commercially available watchdog ICs. The circuit generates an active-high reset signal upon power-up and remains in a low state as long as the control input receives pulses. Whenever the pulsing at the control input stops, whether the circuit is in a high or a low state, th....[Design Idea by VM Holla, Bangalore, India]
Circuit translates A law to m law -  05/07/98 EDN-Design Ideas....Two common methods exist to compand voice for transmission through a PCM channel. In Europe, A law involves converting a 12-bit input signal to an 8-bit encoded output. In the US, m law involves encoding 13 bits to 8 bits. You can use a translator to convert from A law to m law....NOTE  Page includes several designs, scroll to find this one....[Design Idea by Rolando Herrero, Instituto Tecnol�gico de Buenos Aires, Argentina]
