An Easy Way To Roll Your Own Programmable Power Supply
Adjusting the output voltage of a power supply is a feature
typically reserved for highly integrated handheld power-management
units (PMUs) with multiple integrated power supplies. You
can implement this feature, however, with any power supply
by adding a single resistor and an inexpensive digital-to-analog
converter (DAC) (Fig. 1). While this technique isn’t new,
the equations to select... — Marc Davis-Marsh , et al.

Proximity-Sensing Intercom Uses Standard Programmable SoC
Designers can use specialized ICs as a simple way to add touch-sensing
capabilities to a circuit. For instance, the Cypress CapSense
devices can handle several touch buttons and a touch slider.
In some designs, however, one button might suffice. One example
is a “touch-to-talk” intercom application. In this case, a
mixed-signal programmable system-on-a-chip (PSoC) will do.
The PSoC has digital blocks that can be configured as a sensitive
proximity detector and... — Chris Paiano The purpose is as
follows.... we have software video capture program, and we
have an external usb switch mapped to start and stop recording
via a simple momentary button switch. The rub is that there
is no visual feedback that the button has been pushed, eg
that recording is happening. Until the software coders get
around to a send on start to the usb bus, we can't get feedback
out, so we have to fake it by having the same switch toggle
an LED at the same time as it toggles the start/stop button
in the software.
Having constructed several test circuits posted on various
DIY electronics sites, I realize I know too little to make
any needed changes to the designs...and we need it sooner
than I am likely to learn all I need to know. Hence this post.
On power up of the computer, the LED should stay off, and
on pushing the momentary button the LED should go on, and
go off when the switch is pushed again. Very simple in theory.
Not so easy in practice!
I used this bistable flip-flop Circuits Page 9 and substituted
a resistor for the left hand LED, but it is not reliably "left-handed"
on startup. I also added the mentioned 1K resistor in parallel
with the LED to make sure it really goes off as the flip-flop
changes states. I also added a 1uF capacitor to the base of
one of the transistors as was suggested to add a delay and
ensure handedness, but it didn't do what was expected and
I've run out of experimentation time...I need a circuit that
So...the board should be either 5V or 12V, eg power supplied
from a standard ATX power supply, preferably 5V via the USB
bus. It should have one set of terminals for the LED, one
for the switch, and one for power. Otherwise choice of approach
(555 IC, 4013 IC, a modified version of the one I tried) is
up to you, as long as it does those few things.

Micro-Structured Transducer Accurately Measures Pressure
Today’s micro- and nano-structured sensors boast excellent
linearity, resolution, and wide measurement ranges. As a result,
microelectromechanical systems (MEMS) are playing an increasing
role in many more applications. This design describes a novel
use of such a sensor—a non-contact differential variable-reluctance
transducer (NCDVRT)—in the pressure port of a system. The
application involves the selection of a stainless-steel membrane
and... — J. Jayapandian , et al.

Tame Switching Supply Noise While Maintaining Efficiency
A number of situations could benefit from the high efficiency
of a switched power supply, save for the supply’s intrinsically
high noise level. For example, an optical communications application
using a large number of laser diodes could employ a switched
power supply to avoid the need for heat-removal techniques.
However, the laser diodes require a noiseless environment.
A hasty decision to use a switcher would not be rewarding
