Building a low-cost, precision digital oscilloscope – Part 2
Editor’s Note: In this DI, high school student Tommy Liu modifies a popular low-cost DIY oscilloscope to enhance its input noise rejection and ADC noise with anti-aliasing filtering and IIR filtering. Part 1 introduces the oscilloscope design and simulation. This part (Part 2) shows the experimental results of this oscilloscope. Experimental Results Three experiments were…
F1 25 hands-on preview, part one: MyTeam 2.0 goes full team boss by “retiring” the owner driver
The MyTeam mode of the last few F1 games has been arguably the bit that’s most easy to skip or just forget exists. You’d certainly not have missed much new stuff by doing so. Codemasters is aiming to change that with F1 25, though, by introducing the first significant revamp the mode’s gotten since it…
The Last Of Us Part III Should Break The Cycle Of Violence
In a recent interview promoting the second season of The Last of Us, the hit HBO drama inspired by the games of the same name, series co-creator Neil Druckmann had a surprising answer when asked if we should expect a third game to come along and continue the story. “I guess the only thing I…
A pitch-linear VCO, part 2: taking it further
Editor’s Note: This DI is a two-part series. Part 1 shows how to make an oscillator with a pitch that is proportional to a control voltage. Part 2 shows how to modify the circuit for use with higher supply voltages, implement it using discrete parts, and modify it to closely approximate a sine wave. In…

Apple’s spring 2025 part II: Computers, tablets, and a new chip, too
Another week, another suite of press release-only-announced products. With the exception of the yearly (and mid-year) in-person WWDC, will we ever see Apple do another live event? I digress. Some of what Apple’s rolled out (so far…it’s only Wednesday night as I write these words) this week was accurately prognosticated at the end of my…
“Many Startups Selected Under DLI Are Part Of SFAL’s Portfolio” – Sridhar Kaip, SFAL
