TinyPilot: Build a KVM Over IP for Under $100

TinyPilot is my inexpensive, open-source device for controlling computers remotely. It works even before the operating system boots, so I use TinyPilot to install new OSes and debug boot failures on my bare metal homelab servers.

This post details my experience creating TinyPilot and shows how you can build your own for under $100 using a Raspberry Pi.

S42B closed loop stepper motors – No more layer shifts!

If you’ve ever had a failed print from a layer shift, you know how frustrating it can be. Traditionally 3D printers use open loop stepper motors, which means if they lose steps, the printer doesn’t know and can’t compensate. The Bigtreetech S42B is a closed loop stepper motor, which means it monitors the position of the stepper and will compensate for errors. This means no more layer shift failures.

Netflix is testing a ‘Shuffle’ button, because you’re tired of picking what to watch

Does your Netflix home screen — you know, the one with your user profiles — now have a “Shuffle Play” button?

That’s because Netflix is actually planning to bring a shuffle feature to its collection of streaming movies and TV shows, letting you avoid yet another argument with your spouse/housemate/partner/etc about what you’ll be watching this evening. The company tells us it’s actually been running this test since July.

The Ultimate Storage Monster: 32 SATA Ports On A Single Motherboard

Onda has two very peculiar motherboards in the company’s arsenal. The B250 D32-D3 and B250 D32-D3 IPFS motherboards both sport up to 32 SATA ports each.

Chinese motherboard vendors are widely known for creating unorthodox products. For example, Soyo put out an H310C motherboard that supports up to four generations of Intel processors, or Huananzhi, which slapped DDR3 and DDR4 slots on an X99 motherboard. The list of unconventional motherboards continues to expand with Onda’s B250 D32-D3 motherboard.

DIY Smart Lock with Arduino and RFID

You walk up to an invisible lock that only you have the key for, and open it without even touching it. Sounds cool? Today we are going to build a simple RFID-based smart lock using an Arduino as the backbone and a few cheap components.

The technology behind this project is already used in many industries. Anyone who has worked in a modern office or used public transport will probably have used it every day. RFID (radio-frequency identification) identifies data stored on a chip in a card or dongle, and compares them to a list of tags that have already been scanned.

Review : RaspberryPi 4 8 GB performance with max RAM usage. Current and CPU temperature till crash

1. Detailed hardware comparison between Raspberry Pi 4 4GB and 8GB RAM focusing on the change in max specified clock for the two RAM.
2. Step by step set up preparation along with continuous current and core temperature monitor.
3. Whats new in the beta release of Raspberry Pi OS 64 bit.
4. Loading RAM with close monitoring till memory swap starts and then OS kills some apps to release RAM. 5.Conclusion on Core capability with 8GB RAM for potential new usage which was not possible with 4GB RAM version.
