Chapter 11 is off to an interesting start. First, this early circuit is done so that I can use a multimeter to read DC voltage, not AC as in earlier experiments. The circuit from Chapter 10 is stripped down. . . no LED, no electret. Just a trimmer and two pair of matching resistors (2k and 100k). The LM741 chip is still in play, and the schematic in Figure 11. 1 is really easy to understand if you flip back to page 64 and really understand the pinouts of the LM741 and what it's doing in this new.......

The circuit presented here is for a DC-CDI which are used in motorcycles. A DC-CDI is the one in which the high voltage (200-400VDC) is converted from 12V supply voltage. Researched and Submitted by: Abu-Hafss Studying the circuit, we see that it has two parts i. e. the CDI unit, enclosed in the pink box and the remaining circuit on the left is high voltage converter. The working of .......

by Travis Goodspeed extending the work of Thorsten Schröder and Max Moserof the KeyKeriki v2. 0 project. Similar to Bluetooth, the protocols of the Nordic VLSI nRF24L01+ chip are designed such that the MAC address of a network participant doubles as a SYNC field, making promiscuous sniffing difficult both by configuration and by hardware. In this short article,.......

A previous Design Idea de-scribes an astable multivibrator that gets hysteresis from the positive- feedback stage using a technique you can characterize as positive-capacitive feedback (Reference 1). It creates hys- teresis by a charge transfer to its main timing-capacitor. The circuit uses two logic inverters to generate complemen- tary logic outputs. In contrast, the cir-.......

This oscillator circuit permits crystals to be electronically switched by logic commands. The circuit is best understood by initially ignoring all crystals. Furthermore, assume that all diodes are shorts and their associated 1kO resistors open. The two 1kO resistors at the non-inverting input of IC1 (LT1016) set the output to half the supply, ie, +2.5V. The RC network from the output to pin 3 sets up phase-shifted feedback and the circuit looks like a wide-band unity gain follower at DC. When cr.......
