how to convert a 9v battery to 3.7v
A regulator circuit is needed for this DIY project. Familiarity with electronic components, circuitry, the use of a multitester, and a soldering iron is essential. The schematic diagram provided can accept an input voltage ranging from 6 to 24 volts...
USB Live Oscilloscope: ADCV Board
The analog input is initially connected to a fast non-inverting buffer amplifier (OPA353) configured for unity gain, which safeguards the analog-to-digital converter from out-of-range voltages. The ADS830 is an economical 8-bit analog-to-digital converter that accommodates sampling clocks ranging from 10...
A four channel X/Y oscilloscope multiplexer
The project involves the design of a custom multiplexer for a four-channel oscilloscope, allowing for simultaneous display of multiple figures with distinct X/Y inputs. The instrument is intended to enhance the functionality of existing oscilloscopes, particularly in conjunction with analog...
USB Live Oscilloscope: Digital Input Board
The digital input board features eight distinct digital inputs available on connector JP1. Each input is equipped with separate pull-down resistors (RN1, with a recommended value of 1 MΩ) and a Schmitt-trigger. To prevent damage from improper input voltages, HC14...
