The smart home is becoming more and more common with the development of technology, this article will focus on the security aspects of the intelligent access control project.
A sonicator is an ultrasonic device that relies on caviation to emulsify and/or extract substances. This example operates at 28 kHz and has a power of 100W.
This log describe the steps on building a little and practical vacuum tube based audio amplifier, using Soviet vacuum tubes.
This generator will produce two fixed frequency signals to test electronic devices. It is based on vacuum tubes
A remote control that fits in a light switch to send button presses to a Raspberry Pi.
This is a project is about building a midi controlled synth. I will be going through experimentation and planning of such a project. It will be written from my viewpoint, but I will be open to people making suggestions.
Uses hi-Z sounder IPO original hi-bright LED, runs from single 1.5V D-cell.
As the name suggests it, this is a 8 way Scart switch, bound to be mounted on my wall behind the TV.
MULTIMETER AS TEMPERATURE CONTROL VERSION ONE
ABOUT THE CIRCUIT
-Temperature Control Device (TCD) is single bit digital temperature control device which mechanically turns the relay ON and OFF as the result of temperature change.
-It uses normal digital multi meter as temperature reading screen.
- This circuit designed to control temperature in areas where the constant temperature is required throughout, or where the temperature must not exceed or decrease certain temperatures...
