Bookmark or Share- Simple & Inexpensive Ideal-Diode MOSFET CircuitsThe components are inexpensive, consisting of a P-MOSFET (for use in the positive rail) with a dual PNP transistor and two resistors. Q1 and Q2 form a current mirror circuit that act as a differential amplifier which responds to the voltage drop across the MOSFET.
- Making a momentary switch into a latching switchToday a more elegant solution is an inexpensive 8 pin PIC. With proper programming it can deal with switch contact bounce, initial output state and other tasks that would take more components to duplicate.
- Oscilloscope for EMG signals | Electronics Forum (Circuits, Projects ...I am looking for an inexpensive USB oscilloscope for analyzing EMG signals. I found the Hantek 1008A which is an 8CH USB scope. Is this scope good for my application? I know that this scope is used for vehicle testing, but since it is inexpensive and has 8CH (i.e can monitor multiple signals simultaneously) I thought it would by a good option.
- Simple PWM control | Electronics Forum (Circuits, Projects and ...Here's the first of two simple PWM control circuit using inexpensive readily-available components. The circuit component values shown are for a 12V supply but could be altered for other supply voltages less than 15V. Most of the work is done by a CD40106 hex Schmitt inverter IC. U1a/R1/C3 form an oscillator running at ~22kHz.
- An inexpensive yet quality soldering station | Electronics Forum ...Not an advertisement either but as someone that was VERY pleased with the construction and performance of a product received, I'd second Hero's recommendation. I think I ran across MPJA from Hero's recommendation for this iron on a similar post from someone looking for a good inexpensive iron shortly before I chose it.
