- .. bias voltage for Q 2 . The breadboarded circuit’s transformer, T 1 , comprises eight turns of AWG #30 insulated wire wound around the body of an unshielded 100-µH axial-lead inductor, producing approximately 400 mV p-p ...Jan 23, 2018
- .. part of the circuit comprises two conventional noninverting stages. The proposed circuit can be useful in many two-wire or two-electrode applications, in which you need to maintain high amplifier input-impedance values. Figure 2. ...Nov 24, 2017
- .. At the same time, the minimum-allowed transmitter-terminal voltage, which determines the maximum loop length for a given wire gauge (or the minimum wire cross-section needed for a given loop run), should be minimized. The transmitter ...Oct 20, 2017
- Rex Niven.. the host. Figure 1. A typical LCD module. This hardware interface Design Idea (Figure 2) reduces the connection to just one wire, allowing a basic microcontroller with limited I/O to drive a large display, either directly, through a standard ...May 24, 2017
- .. (as in a relay or transformer) unless you can remove the iron. The resulting coil should be a simple solenoid like wire wrapped around a nail. Don't try to wind your own it takes too many turns. Evaluate several coils simply by ...May 9, 2017
- .. L1 22 mH Inductor, 5% tolerance L2 0.68 mH Inductor, 10% tolerance L3 3.85 µH Inductor, 27 turns of AWG #28 magnet wire hand-wound on T37-2 mixture (Carbonyl E) toroidal core S1 NA DPDT panel-mounted toggle switch J1, J2 NA 50 W BNC ...Apr 26, 2017
- .. interface (not shown in Figure 1) features the ability, using the SDI input, to daisy-chain several ADCs on a single 3-wire bus and provides an optional busy indicator. It is compatible with 1.8 V, 2.5 V, 3 V, and 5 V logic, using the ...Mar 14, 2017
- Stephen Woodward.. the surface of a heated sensor and the ambient air temperature increases as the square root of air speed. The popular hot-wire anemometer exploits this principle, but it suffers from the disadvantage of using a specialized and fragile ...Jan 31, 2017
- .. current may be harvested from the doorbell transformer by using the voltage across the open switch, leading to a simple two-wire connection. To ring the doorbell, the device shorts its supply, and an electrolytic capacitor keeps the ...Jan 18, 2017
- .. of the circuit in Figure 1 uses one-half of a 12-bit-current-output AD5415 dual DAC that operates as a voltage divider. Wire the split-feedback resistors, R FB and R 1 , to produce a composite-feedback resistor equal in value to the ...Nov 18, 2016
