Precision Digital Altimeter - The current concept incorporates a wireless
transmitter and receiver and is thought to be used for remote controlled airplanes or
appliances with two seperate parts. In other words, we have one dedicated transmitter
(acquisition, filtering) and one dedicated receiver part (user-interface, look-up
table, calibration, storage),.....(added 4/05) |

Programmable Charger Fills Capacitor Banks - 10/08/98 EDN-Design
Ideas.....Designed for the use with a pyrotechnic pulse generator, the charger in
Figure 1 uses low-cost components to charge the C1 capacitor bank to a voltage
as high as 75V, or to 25V in a few seconds. A 555 timer, IC1, controls a flyback
converter via the Q1 transistor switch.....Contains several designs, scroll to

Programmable oscillator uses digital potentiometers - 7-Mar-02 Issue of EDN
Digital potentiometers are versatile devices; you can use them in many filtering and
waveform-generation applications. This Design Idea describes an oscillator in
which setting the resistance of two digital potentiometers independently programs the
oscillation amplitude and frequency. Figure 1 shows a typical diode-stabilized Wien-bridge
oscillator that generates accurate sine waves fro..... [Design Idea by Alan Li, Analog

Pushbuttons and digital potentiometer control boost converter - 17-Feb-05
Issue of EDN Digitally controlled potentiometers are useful for generating
analog control voltages under the control of a microcontroller. In some applications,
manual pushbutton switches could replace a microcontroller and simplify product
design. Mechanical switches exhibit contact bounce, and, when a user actuates them,
they may open and close many times before reaching a stable state..... [Design Idea by
