- Ana Gómez Jorge MarcosMany electronic-control systems have digital outputs that use transistors. One method of improving the security in these outputs is to use an oscillating signal to represent a logic-high state instead of a fixed voltage level (Figure 1). This type ...Dec 19, 2022
- Stephen WoodwardWhen applied to pharmaceuticals, the term “off-label” suggests the (frequently discovered) practical and beneficial uses for a drug that are different from the one it was originally developed for. This happens for electronic components ...Oct 28, 2022
- John GuyAs Moore's Law plunges us into the realm of multigigahertz processors and PCs with gigabytes of RAM, engineers face the task of removing the heat that these state-of-the-art components produce. Cooling such systems poses a dilemma. If you ...Aug 15, 2022
- Kunal VermaIn this project, we will be using the ESP8266-01 Wi-Fi Development board to make a small IoT home automation that has Wi-Fi featured in it. The system operates on a local web server and is easy to use for the novice. With this project, we can ...Aug 9, 2022
- V GopalakrishnanWith just a few NAND gates, you can control sump pumps and other pumps that keep your basement from flooding and maintain water levels in tanks. The circuit in Figure 1 receives 12 V signals from L 1 , the lower water level, and L 2 , the upper ...Aug 4, 2022
- Kieran O'malleyAlthough rechargeable batteries offer many advantages, they can suffer damage and shortened service lives if they're fully drained of their charge. The circuit in Figure 1 shuts off a battery-powered appliance in this instance, an LED ...May 30, 2022
- Sajjad HaidarPower control using the linear region of an active device, such as a MOSFET, is not an efficient option. However if the range of power control is restricted to the lower or upper end of the range, using the linear region is not a bad choice. For ...Apr 7, 2022
- Raju BaddiThe simple circuit in Figure 1, which can be powered with a 3.6 V nickel-cadmium rechargeable battery, lets you use an LED to detect light. The circuit consumes practically no quiescent power. Two LEDs act as photodiodes to detect and respond to ...Mar 8, 2022
- Anthony SmithMost readers are familiar with the current-limiting circuit in Figure 1, in which the load current, I L , is limited to a value of where V BE is the base-to-emitter voltage and R S is the sense resistance. Under normal conditions, in which the ...Feb 27, 2022
- Paul MoffatI was using a thermoelectric cooler for a camping trip and discovered the next morning that my car battery was dead from the load. I never expected a 3.5-A load to drain the battery in eight hours. So I went about making a circuit that could be ...Dec 1, 2021
