Opensource USB HUB
https://www.electronics-lab.com/opensource-usb-hub/
Christian @ hackaday.io build his own USB Hub based on GL850G IC: I was looking to make a custom USB Hub for a project but I couldnt find any of them that worked and using the chip GL850G. The chip is pretty old and cheap, but in my case I didnt need to use any […]
Store Data in Nanomagnets
https://www.electronics-lab.com/store-data-nanomagnets/
Imagine if a bit of data can be stored in a single atom or a small molecule, then massive volumes of data can be stored in a tiny amount of space. This theory was the topic of a research tries to develop a new method to store data magnetically in atoms. As the magnetization of an atom can […]
Pool Buddy – Monitor your pool water quality
https://www.electronics-lab.com/pool-buddy-monitor-pool-water-quality/
Monitor and log water quality (pH & ORP) and temperature from everywhere. Instead of performing regular checks with tester kits to maintain adequate pH and chloride levels in our (small) swimming pool, I decided to build a project that monitors the water continuously and registers the data online so I can easily inspect it. Pool […]

Bosch glue pen teardown
https://www.electronics-lab.com/bosch-glue-pen-teardown/
electrobob @ electrobob.com tipped us with his latest teardown of a battery powered Bosch glue pen. He writes: On the right side we can see the fuse and a IRF3711Z 6mΩ 20V HEXFET driving the heating element. At the glue melting end there is no temperature sensor, they are probably relying on the positive thermal […]

Integrated Load Switches versus Discrete MOSFETs
https://www.electronics-lab.com/integrated-load-switches-versus-discrete-mosfets/
Alek Kaknevicius @ ti.com discuss about load switches and the advantages of intergrated switches over discrete ones. The most common approach to load switching solutions is to use a Power MOSFET surrounded by discrete resistors and capacitors; however, in most cases using a fully integrated load switch has significant advantages. While both discrete and integrated […]

Water Out Of Thin Air
https://www.electronics-lab.com/water-thin-air/
Due to the advances of technology, we are able now to produce water out of thin air without using the resources usually applied like mains utilities. Such approach would be perfect in places that lack natural resources like deserts. Working from the effects of direct solar radiation, a group of researchers at UC Berkeley had designed such […]
Soldering pen for Weller RT tips with OLED display
https://www.electronics-lab.com/soldering-pen-weller-rt-tips-oled-display/
vlk @ hackaday.io build a very nice soldering pen with a OLED display. I found some projects where is used Weller soldering tips designed for WMRP soldering iron with standard 3.5mm jack and inside the tip is also thermocouple for sensing temperature. These tips are not so cheap but the quality is really great, especially […]
