*WARNING* This design needs to be revised if you intend to use interrupts for the encoders. I will rework the entire thing to address a few issues, se be warned if you base your design on it.
MSP430-based voltage and current adjustable power supply. Aiming for 0-12V, 0-1A, but can easily be modified for higher voltages and currents. No pre-tracking switchmode for now, might be a good idea for h...
Current Limited Variable DC Supply
A Positive and Negative (+-)2-15V Voltage Regulator Schematic
This is a small pcb that is designed to be used on an electric go-kart to display a stopwatch, motor RPMs, and cart speed as well as record this data on an SD card with a time stamp for analysis. The project is Arduino based and is ran off of 7-59 VDC or directly from a 5V source through any of the 5V or VIN pins on the data logger shield (this is not a protected input). It is designed to have w...
Моя попытка спроектировать регулируемую плату PowerBank'а для ноутбука и/или телефонов.
Проект пока находится на стадии разработки.
P.S. приоритетом данной платы является разводка на одной стороне и компактность.
This simple SMD board can supply 40-300VDC from a 12VDC for Nixie Tubes.
Original design not by me, I just created the board.
Tested and works.
A friend of me side radio amateur office. He wants Variable Regulate Power Supply high current about 10A go up. I then advise this circuit, because build easy. Read more :
[**1-20V, 10A Adjustable DC Power Supply using LM338**](https://www.eleccircuit.com/1-20v-10a-adjustable-dc-power-supply-by-lm338/)
This project - an attempt to repetition (with slight modifications) device developed by Leonid Ivanovich: http://radiokot.ru/forum/viewtopic.php?f=11&t=59168.
A basic lab/bench power supply that I'm designing from bits and pieces around the web. One of my goals is to build this PSU with as many recycled components as possible.
Sources I've drawn from:
This Is Very Easy To Make And It Work Very Good I'v Tested this to 2.5 amps load good result
A power supply for a nixie clock. I am using IN-14's, but almost any type should work just fine.
You can order the PCB cheaply(4pc for 13$, free worldwide shipping) at https://PCBs.io/share/4KX2j
Convert positive voltage to negative one
Conversion old unregulated Tandy power supply to regulated 9 and 5 volt output.
Has also the little Voltage Sensor on board.
A new life for this power supply after 35 years, spending most of it in the attic. Had only a transformer,
capacitor and rectifier bridge. It had a fuse a long time ago ... Mostly all recycled parts with some new in the mix.
