.. that meld the functions of sensor and heater into a single device: FET, BJT, or even a simple length of fine gauge copper wire. A virtue inherent in thermostat designs that use a transistor as combined sensor and heater is that independent ...
.. drives a DS2423 pulse counter. A host PC or µC reads the output of the pulse counter via the Dallas Semiconductor one-wire bus ( Reference 1 ). The circuit uses approximately 150 µA of current, allowing the circuit to steal its ...
.. system comprising a solar photovoltaic panel mounted outside sustainably converting sunlight into electrical power a run of wire to conduct said power into the interior, then suitable circuitry and LEDs to re-convert the delivered power back ...
.. for a bulky, multipole switch; the feature works with just one pole. The design uses a PCB-mounted phosphor-bronze-plated wire against a gold post, an almost no-cost and no-real-estate switch. Without a processor or a digital clock, the ...

.. First, prepare these materials: Core: ferrite, EE-20-10-6 (B66311G0000X187) Primary winding: 2.88 mH (124 turns of 0.2 mm wire) Gap: around 0.25 mm (mathematically) Secondary winding: 6 turns of 2×0.7 mm wires (two 0.7 mm wires in ...
.. industry, in which the goal is to produce cars with simpler, lighter wiring looms, any interface that uses just one wire instead of two offers a distinct advantage. The circuit in Figure 1 implements a bidirectional link using a ...
.. DI (see the Figure 1) follows the melded concept but takes it in a somewhat different direction by using fine gauge copper wire (e.g., 40 AWG polyurethane insulated) as an integrated temperature sensor and heater. Figure 1. Miniature ...
.. can use two simple bipolar transistors to latch-off the whole SMPS in the case of an optocoupler failure (Figure 3a). You wire the bipolars in a thyristor manner using a dual-transistor device, such as the MBT3946D . a) b) Figure 3. You can ...
.. is ostensibly a buck converter to provide a 5 V output. The optimum solution would be a bifilar wound coil with heavy gauge wire for the main 5 V output and smaller wire for the overwinding. To avoid a custom coil design, an off-the-shelf ...
