Raspberry Pi CM0 System-on-Module Available on AliExpress Starting at $33

Raspberry Pi CM0

The Raspberry Pi CM0 system-on-module is now available on AliExpress for $33 and up from various resellers, many of which claim to have several thousand in stock. The Raspberry Pi Compute Module Zero was introduced last year with a Raspberry Pi RP3A0 SiP with 512MB RAM,  optional 8GB or 16GB eMMC flash, optional WiFi and Bluetooth, and castellated I/Os, or basically a Raspberry Pi Zero 2 W in Compute Module form factor. There’s just one little issue: it’s only officially sold in China, and the only way to get one is to get a development board like the Makerfabs CM0IQ or a complete product such as the ED-AIC1000 smart camera or ED-IPC1100 industrial box PC. Raspberry Pi CM0 specifications: SiP – Raspberry Pi RP3A0 SoC – Broadcom BCM2710A1 CPU – Quad-core Cortex-A53 processor @ 1.0 GHz GPU – VideoCore IV GPU supporting OpenGL ES 1.1, 2.0 graphics VPU – H.264/MPEG-4 […]

Five Accessories for 3D Printers That You Can Make with Your 3D Printer

considering the purchase of a 3D printer, it’s important to understand that it’s not just a matter of turning it on and watching it create your wildest ideas. 3D printers necessitate various tools and accessories to ensure the machines are kept clean and in good working order. You might be able to acquire these items on Amazon if you’re willing to incur the extra cost, but since you already own a 3D printer, why not utilize it to produce the very accessories it requires?

With appropriate designs and some filament, your 3D printer can generate useful enhancements for your 3D printing environment, ranging from storage shelves and spool rewinders to printing bed scrapers and cleaning tools. With a bit of creativity, you can create all sorts of fantastic instruments, but if you’re in need of some motivation, you can explore 3D printing enthusiast websites, such as Printables or Maker World, to discover various designs and concepts.

Comprehending the Significance of a Steam Deck LED Flashing Three Times

gaming laptop, you may consider investing in a Steam Deck. The console offers exceptional value in the portable console arena, but you will eventually need to put it away. When you do, the console will indicate this with a useful — although somewhat perplexing — LED signal.

Each Steam Deck features a setting called “battery storage mode” that aims to preserve the battery’s health when you don’t intend to use the device for extended durations. When this mode is engaged, the power LED will flash three times. However, this is only true for LCD Steam Decks. OLED Steam Decks utilize a different signaling method: The LED will flash blue twice.

Although battery storage can keep the Steam Deck’s battery in good shape for weeks or even months, it achieves this by effectively severing the connection between the motherboard and its battery at the BIOS level. Consequently, once you enable this mode, waking the Steam Deck through standard methods (i.e., pressing the power button) is not possible. To continue using the device, connect it to a power source, such as an outlet, then press the power button. It’s a bit of a hassle, but it ensures the battery remains in excellent condition. Additionally, if you plan to DIY repair the Steam Deck or, for instance, upgrade it with a higher-resolution display, you should turn on battery storage mode in advance to reduce potential risks.
