Bus Pirate 5 is the latest version of the multi-tool hackers trust since 2018. RP2040-based, color LCD, 1-5volt power supply and IO buffers, and more! Firmware, hardware and a fresh new forum are hosted at BusPirate.com, which I rescued from spammers a few years ago. The software...

Happy New Year! Thank you for reading the blog and being part of our community in 2023! We’re looking forward to more open hardware projects, more how-tos, more videos, more free PCBs, and more hacking in 2024.

Merry Christmas and Happy Holidays to all. May you find many PCBs and other electronics wizardry under your tree or pole. Remember, support is available on Christmas. Just give us a shout in the forum.

App note from Bourns’ comparing current shunt resistors and hall effect current sensing pros and cons. Link here (PDF) Current sensing is an essential design function that is necessary in a broad range of applications. For example, current sensing is needed to detect a battery’s ...

Bourns’ new thermal cutoff device for LED protection can be found in this paper. Link here (PDF) Compared to traditional lighting technologies such as incandescent and fluorescent lamps, LED lighting has a much longer life span, consumes far less energy and offers shock and vibra...

App note from Bourns on linear motion potentiometers and how they can be used to detect position by voltage division ratio. Link here (PDF) The elements of the LMPs are manufactured with conductive plastic (CP) for extended wear capabilities. Unlike Trimmers, which are “set and f...

Great read from Bourns’ white paper about the new SiC Schottky diode which revolutionize power handling capability and other benefits compared to Silicon diodes. Link here (PDF) For diode applications, the ideal component would be one with no voltage drop during forward conductio...

App note from Bourns about the robustness of trimmers used on surveillance system, typically sealed to protect agaisnt harsh environment. Link here (PDF) Trimmer technology is designed for use in applications where the unit must be calibrated before it is shipped to a retailer, a...

App note from Vishay going back to the fundamentals of humble fixed resistors. Link here (PDF) In the shadow of microelectronics, passive components such as discrete resistors would seem to have fallen out of the field of view in electronics. Yet, it is the rare circuit that can ...

Nexperia’s app note on their load switches, combining multiple load switch functions in to one chip. Link here (PDF) Nexperia load switch ICs are highly integrated Power Management Integrated Circuits (PMICs) designed to efficiently control power rails within electronic systems. ...
