Pretty little 4V Sealed Lead Acid (SLA) or Sealed Maintenance Free (SMF) batteries are widely used in portable electronic gadgets such as mosquito bats, kitchen scales, healthcare instruments, etc. The most common 4V SLA rechargeable […]
Recently I have received a few messages from a follower who is interested in making a simple relay box that will help him operate some regular electrical devices using the control signal from a common […]
This post describes the construction of basic crystal oscillator. The key parts in the experimental setup are a KDS4.000 quartz crystal (4.000MHz) and a SN74HC04N hex inverter IC. It should be easy to use an […]
Mixtile has just unveiled 18% OFF discount for pre-ordering the Core 3588E. Mixtile Core 3588E System-on-Module (SoM) is driven by the potent RK3588 chipset, delivering impressive performance while consuming minimal power. Key features of this […]
Circuit configuration of a Window Comparator usually consists of a pair of inverting and non-inverting voltage comparators in which the output indicates whether an input signal is within a voltage range defined by two different […]
Every once in a while, I have found myself needing a quick circuit to blink a light emitting diode. It is quite easy to build simple microcontroller circuits which performs this task thru a few […]
The decade resistance box is an indispensable test gear for any electronics lab as it can be used to substitute different values of resistors during prototyping and/or experimenting with electronic circuits. Using it is easy […]
An optocoupler, simply put, is a little device consisting of an independently-powered light transmitter and light receiver unit packed inside a light-proof shell that can be optically coupled together. Actually optocouplers are very easy to […]
The real inspiration for this post actually came from lots of lame designs seen on the web. The last drop was a reasonably great written article presenting a number of blueprints to build timer circuits […]
Do you know? You can govern the speed of brushed DC motors without any additional sensors, but using a basic characteristic – the speed-dependent back EMF (BEMF) voltage! The BEMF motion control technique has been […]
