AOC 16T20 Portable Monitor Packs a Budget Full HD Second Screen for Travel

By Jackson Chung October 3, 2026

AOC sells the 16T20, priced at $47.49 (was $70), as a 16-inch portable monitor, though the panel itself measures 15.6 inches on the diagonal. Resolution sits at 1920 by 1080, the panel type is IPS, and the refresh rate tops out at 60 Hz. AOC lists a 4 ms gray-to-gray response time, 178-degree viewing angles, a rated brightness of 250 nits, and a static contrast ratio of 1200:1. Color depth is 6-bit, which works out to 262,000 colors. Independent tests have come in a little short of the brightness claim, and the color range is narrower than a desktop monitor built for photo work. For email, documents, video calls, and a movie on a hotel desk, the panel holds up well enough that the low price starts to make sense.

Peter Knetter’s YouTube in Game Boy Puts a Handheld Through Studio Work

By Bill Smith October 3, 2026

Peter Knetter has spent years asking old machines to do a modern job. His series, YouTube in, treats a console or a dusty operating system as a whole production desk. A few days ago, he posted the one fans had been waiting on. ‘YouTube in Game Boy‘ documents his journey to make a YouTube video using only a Game Boy.

Penguin DIY Built Invisible Earphones That Vanish Inside a Custom Ear Cast

By Jackson Chung October 3, 2026

Penguin DIY started with a pair of ordinary true wireless earbuds and finished with two objects that barely read as audio gear. One half is a clear resin plug cast from a mold of his own ear, meant to sit fully inside the canal. The other half is the tip of a pen. Both still pair to a phone over Bluetooth, and both still take a charge from a case he opened and rewired so the original contacts could reach the new shapes.

Gamer’s GCVHS Project Brings Night Trap, Mario, and DOOM to a VHS Tape

By Bill Smith October 3, 2026

Throaty Mumbo already spent an hour proving a vinyl record can cough up a SEGA game if you are patient enough and a little mean to the format. His follow-up, posted as Can We Port Video Games to VHS?, asks the meaner question. A cassette is linear. A videotape is also linear, except it also carries a moving picture, two audio tracks, and a deck that can be told to wind forward or back. GCVHS is his attempt to turn that mess into a console.

Living Muscle Cells Power a Paper-Thin MIT Aquabot Through a Maze

By Jackson Chung October 2, 2026

Living muscle cells, the same kind that pull on bone inside a body, now pull a paper-thin robot through water. Researchers at MIT built a gum-stick-sized aquabot whose two fins beat when light hits them, and they steered it through a simple maze in a petri dish by flashing that light from outside the dish.
