Hugo just turned one, and to celebrate we bought him a Duktig kitchen from IKEA. Like everyone else we painted and added fake subway tiles, but I wanted to take it a bit further and add a working microwave panel. Hugo is obsessed with pressing...
Somehow, I was busier with life and work than I was during grad school, when I built my first two Mechs, so Numa 2 took me 3 years to finish. Major components of this work included: - Converting the original Numa's C++ codebase into micropython...
If external power is connected to the tinyUPS the input voltage or vcc of the ATtiny13 is delivered by this source, otherwise by the battery. The ATtiny13 monitors the input voltage and tells the connected device to shutdown by pulling the SHUTDOWN-line...
Theory of Operation The project is split into two circuit boards. The one on the left is the battery, the other is the power supply. The battery board holds six Lithium-Ion cells, the protection and charger circuitry, and a microcontroller to keep track...
A note of caution! This project involves the repair of a 15W CO2 Laser! Appropriate certified Laser safety glasses and safe working practices are a requirement if you intend to duplicate any of the work described here! Additionally I have heard remarks...
An RFID or radio frequency identification system consists of two main components, a tag attached to the object to be identified, and a reader that reads the tag. A reader consists of a radio frequency module and an antenna that generates a...
A K-type thermocouple is a type of temperature sensor that is widely used in industrial applications to measure temperature. It is made up of two different metals, typically nickel-chromium and nickel-aluminium, which are joined together at one end to...
This project was developed in partnership with the company JLCPCB. When performing the reading, you get 5 free units of a printed circuit board for you to assemble your project. The automatic fish feeder with Arduino is a great idea for anyone who wants...

1) Oxygen saturation and Covid-19 In this incredible period of our life we've learned a lot of things about viruses, lungs, surgical masks, soap and washing hands. Everybody read about symptoms like coughing, fever and breathing difficulties....
How can light accelerate healing?Although having super powers would be fun, it is not possible at the moment. However, accelerating healing through light is possible and is backed up with years of research from the likes of NASA, the Military, and Research...
The Internet of Things has made it easier than ever to set up a smart home in which you can remotely control your door locks, lawnmowers, lights, thermostats, vacuums, and even pet feeders, using your smartphone and an app. It's also made it very easy...
Overview Kelp forest decline is a severe global climate problem. In Northern California, more than 90% of kelp forests along 350 km of coastline were lost [1]. Satellite View Northern California kelp forest coverage. Image source: Meredith McPherson...
