“This project is a simple linear bench power supply with adjustable voltage and current. It is meant to be a learning experience, putting ideas of circuit design, feedback, stability into practice building a complete practical power supply. I have intentionally …
“I have been using Nathan Chantrells Tiny328 for quite some time as my swiss army knife ISM radio node. Now I wanted a more slim ISM node as my setup with a Tiny328 on a breadboard is not very deployable …
“This is cheap adjustable 0-30V 3A Laboratory DC Power Supply circuit. It is high efficiency regulator circuit by using IC regulator UA723 and TIP3055 as power transistor so easy to install. It is designed to protect over current load maximum …
“This is a small bench power supply that is powered by two lithium-ion batteries. The project was inspired by Dave Jones from EEVblog but the design is completely mine. The voltage range is 0-20V regulated in 10mV steps and maximum …
“I found a very nice toy of the case. I was thinking trying to make a very nice clock with the toys of the case.”
“I have updated the Attiny85 keychain game making it easier to source and assemble. The new snap case has been updated to allow enough height for the screen header as well as a factory made CR2032 battery holder.”
“Ive got a lot of relays in the parts bin with 24V coils. This is a common control voltage in industrial and telecommunications equipment, so the relays are common in surplus equipment. Many will actuate equally well on AC or …
“Recently i made shield for arduino which can measure ECG, respiration, eventually after some changes in PCB and code, EEG and EMG. Big advantage of this shield is possibility to make it easily at home. The shield is equipped by …
“A logic probe is not only the poor man’s logic analyser but often more usable.”
“Current Sensing Switch is designed to operate a Relay Contact when there is a DC current through the sense resistor exceeds the set point, Set point adjustable from 1A to 3Amp using on board potentiometer. This circuit can offer over …
