LEAP#389 Two-Stage Amp Design
Reviewing techniques for two-stage CE amplifier design.
Gobsmacked that my calcs put me within 3% of actual performance,
and I got a workable Class A amplifier to boot!

LEAP#387 GPS Modules
This is the first time I’ve played around with a GPS module, so it was an interesting dive into NEMA standards.
But at the end of the day, the TinyGPSPlus library makes it a piece of cake
to get GPS readings. I log these to serial and display the main facts on an LCD.

LEAP#386 The Blue Pill
Popularly known as the Blue Pill, the STM32F103C8T6 Minimum System Development Board seems like an excellent gateway drug for getting into ARM Cortex-M3 development.
This is particularly true as it is possible to program it with the familar Arduino IDE.
It is my first look at one of these boards, so I have simple expectations - follow along some of the tutorials on the web/youtube and at least get a simple program running on the board. In the process I’ll learn a bit more about the board’s capabilities and quirks.

LEAP#385 BoldportClub Widlar Blinky
The µA723 voltage regulator is a classic from 1967, and was celebrated in the Boldport Club “Widlar” (Project #21). It is a bit boring to just regulate voltage, but since the µA723 contains an error amplifier and voltage reference … yes, it is possible to make an oscillator instead. My version of the Widlar glows an orange LED…
