390Ω in the opto-led circuit means that ~5mA passes through the opto-coupler when ever the probes are touched. 5mA is the design current for the X-suffix EL816 (salvaged from a commercial fluorescent ...

We’re interested in any device that can make a PCB out of a copper-clad board, and this entry for the Hackaday Prize might be the simplest machine for PCB fabrication yet. It’s called t… ...

Δ V (T ) = 2.8 × 10 – 4 T This equation predicts outputs of Δ V = 20.5mV at -200°C, 83.4mV at 25°C and 132.0mV at 200°C. Amplification using op amps can boost the output to the required level. In the ...

Manufacturing and Utility plants depend on their IIoT devices such as PLC, CNC, SCADA Systems, HMI, robots and more, to achieve their production goals. These devices and their logic programs are vital ...

From the micromixer topology by Barrie Gilbert [1], this amplifier allows a single-ended input to be converted to a Class A/B current output from a single supply. Wow the engineering world with your ...
