- David Johnson-Davies.. is 0.000001 ohms. I often use it to measure contact resistance of a relay or the resistance of big chunk of heavy gauge wire or the resistance of a copper trace on a circuit board. You can also use it to measure the voltage drop of a ...Jun 26, 2025
- Jayapal Ramalingam.. “DIY RTD for a DMM” ( Ref. 1 ). With a fortnight’s struggle, I completed the design of 4 mA to 20 mA, two-wire temperature transmitter using a platinum resistance temperature detector (RTD) sensor, as shown in Figure 1. ...Jun 11, 2025
- Stephen Woodward.. fabrication of supersharp, atomic-scale needle tips. One way to make the tips is to etch them from short pieces of platinum wire in a calcium-chloride electrolyte bath. Applying an ac voltage between the electrolyte and the wire generates a ...Jun 9, 2025
- Will Hadden.. attenuation between H 1 and W 1 (pins 11 and 9). The IC contains two potentiometers controlled by a 16-bit code via a three-wire serial interface. To set the LED current, drive RST high and clock 16 bits into the D terminal of IC 1 , starting ...Apr 14, 2025
- Tim Davis.. circuit board (PCB) with ground plane. The board used a special scope probe-tip test point with a fitted, spiral ground wire, into which the probe’s ground-sleeve can fit. (This technique is often employed to reduce parasitic ...Apr 9, 2025
- Rod Elliott.. where it's easier, cheaper and more convenient to use the circuits shown than to have to source relays, or to try to wire up CMOS switches for muting. While it is possible to use the ideas shown here for source switching, there will be ...Apr 1, 2025
- Swagatam Majumdar.. set-up of an antenna. Placing an antenna in a close proximity of a large metal object helps generate additional power. The wire of an antenna should be more than 150 feet long, which has to be placed horizontally on a higher platform to ...Jan 15, 2025
- Mark D Braunstein.. the system shown in Fig. 1, you can quickly test a cable containing twisted-wire pairs and detect open or reversed pairs, shorted pairs, and shorts between unrelated pairs. The tester consists ...Nov 11, 2024
- Mike Hardwick.. 1 depicts a subsystem that receives power from its host system and simultaneously transmits a clock signal back on the same wire. The circuit uses the clock in the remote system to modulate power-supply current via an open-collector driver or ...Oct 3, 2024
- Alexander Bell.. shipping moving-coil meters, manufacturers may short-circuit the meters' terminals with a length of wire, which provides effective electromagnetic damping and results in better immunity to external mechanical vibration ...Sep 30, 2024
