Over the last half decade I have developed 100+ projects. Well, some are barely projects in my opinion. These are mini projects like dev kits, proto modules or project snippets.
They aren't good enough to document individually. But when gathered around together, these look like a family of minions with some big brothers. Starting from LEDs to Power Supplies, Programmers to Driver Modules - there are lots.
Enjoy your tour of my Electronics Art Gallery!
Let's talk about Power Supply projects. I made this one capable of delivering fixed 3.3 and 5.0 Volts, 1.25 - 6.0 Volts adjustable and 9-25 Volts boost capable power by a rechargeable Li-Ion battery.
Now, sometimes you need to buck (step down), boost (step up) or create negative supply for Opamps. Here are some of my Buck/Boost/Invert converters based on MC34063 IC:
Plug and Play 5V out module for using with 3-5 watts solar panel:
LED modules with pre-soldered series resistors:
Some IR LEDs:
Switching current with the relay or transistor, ready to go with any microcontroller:
More switches - mechanical:
Some electronics signal switches:
Loading Arduino codes to unofficial AVRs, an SPI programmer with little bit of proto area and a Touch+UART input board from Cypress:
How about fuse for breadboard?
A DAC (Digital to Analog) voltage converter module - any PWM will become Analog voltage:
A speaker driver based on LM386:
And what else?
A motor driver module!
Strip a relay and get an Electromagnet Coil to make a programmable magnet. There is a vibration motor module, too.
Remember ESP8266 board with the stupid pinout, well, here is the dock for boradboard programming. One for Arduino Uno, too!
Some failed prototypes are:
As for my complete projects and work in progress projects:
Some of these are documented on Hackster. Don't forget to check here.
Thank you for your time.
