Simple Kitchen Timer Circuit – Egg Timer
A kitchen timer is a useful gadget which produces an alarm sound after a predetermined delay, as set by the user for specific time based food recipes that must be cooked only for a certain amount of time for best results. Written By: Suneeta Dixit One example is boiled eggs which may be either hard […]
Circuit Tester Probe – PCB Fault-Finder
This simple circuit tester probe can be used for detecting short circuits, abnormal resistance conditions, continuity breaks etc inside an assembled circuit board or a PCB. The indication will be through an audible buzzer sound or an LED illumination. The described designs are all extremely safe to use even with PCBs that may have highly […]
Cup Full Indicator Circuit for the Visually Challenged
This circuit basically is a fluid level alarm indicator intended for alerting visually impaired individuals regarding the liquid level in a container such as cup, glass or bowl. The unit can be simply hooked up across the rim of any container with the probes such that it detects the full level liquid in it while […]
Simple Ni-Cd Battery Charger Circuits Explored
In this post I have explained many simple NiCd charger circuits with an automatic overcharge protection and a constant current charging. When it comes to correctly charging a Nickel-Cadmium cell, it is strictly recommended that the charging process is halted or cut off as soon as it reaches the full charge level. Not following this […]
Listen to UHF and SHF (GHz) Bands with this Simple Circuit
This simple two IC circuit can be used for capturing and listening to frequencies in the GHz range. Receivers designed to cover frequencies as high as several gigahertz (which is many thousand MHz!) are generally difficult to find, specifically for anyone who is looking for cheap versions of these gadgets. However, it may be possible […]
