PiFinger is a Fingerprint HAT for Raspberry Pi (Crowdfunding)

“There’s a HAT for that” they say, or something close to it… We’ve covered many HAT expansion for Raspberry Pi boards over the years, but so far, I don’t think we’ve seen any HAT with a fingerprint sensor, probable because tiny USB fingerprint readers are a thing. But if you’d like a HAT with a built-in fingerprint sensor, the guys at SB Components have you covered with PiFinger HAT equipped with a 2D capacitive fingerprint sensor and a small display. The expansion board is also powered by a Nuvoton Cortex-M23 MCU with Arm TrustZone support and on-chip crypto-accelerator. PiFinger specifications: SoC – Unnamed Nuvoton Arm Cortex-M23 microcontroller with Arm Trustzone (likely NuMicro M2351 since it’s made for fingerprint applications) Display – 0.91-inch OLED display Sensor – 2D capacitive fingerprint sensor with 176×176 resolution connected to MCU over SPI Host interface USB to computer UART up to 115,200 baud + GPIO […]

HotDive converts your smartphone into a dive computer and underwater camera (crowdfunding)

Many recent phones are fitted with a pretty good camera, and some are waterproof, but not quite enough to go snorkeling or diving. If you could, your phone could also double as a dive computer, and that’s exactly what HotDive provides: a waterproof enclosure for your smartphone allowing you to dive up to 80 meters deep, and convert your phone in a dive computer, underwater camera, and fill light at a fraction of the cost of specialized diving equipment. HotDive enclosure includes an independent auto-pump air extraction system creating a vacuum for your smartphone to make sure all photos are clear of fog, as well as a fill light to take clear photos even during night dives. The fill light is made of CREE LED lights delivering 800 lumens, and providing with 130° illuminance and 5800-6500K sunlight-like color temperature. The HotDive Pro version includes hardware to create a built-in dive […]

DIY Pi KVM: An easy and cheap KVM over IP for Raspberry Pi

Traditional IP-KVM systems may cost you hundreds of dollars. DIY Pi KVM over IP is a very simple and fully functional Raspberry Pi-based KVM over IP that you can make yourself. If you do not know what IP-KVM is, it stands for keyboard, video, and mouse. It allows you to connect to a computer or a server remotely. With this, you can fix problems such as configuring the BIOS or reinstalling the OS using a virtual CD-ROM or flash drive. You can see the v2 example implementation in the above image. Pi-KVM v0 and v2 are ready-made images available for download for Raspberry Pi. You will find all the required hardware in the “Getting Started” section for the v0 and v2 platform for Raspberry Pi. In the figure below you can see the B101 HDMI-to-CSI bridge connected to the Raspberry Pi. The team is working to launch the v3 board […]

CodeBug Connect IoT development board is designed for young makers (Crowdfunding)

In 2015, a UK-based team launched a mini IoT development board called CodeBug. The same team has now come up with the CodeBug Connect IoT Development Board. CodeBug Connect is a new wearable micro-computer that brings IoT to everyone and aimed at educators and young makers. Upgrade to the original CodeBug This comes as an upgrade to the original CodeBug. The new development board retains its original cuteness and petite proportions but adds full color to the grid of 5×5 LEDs. The original buttons have been upgraded to mini joysticks, making them more suitable for games. The touch-sensitive, croc-clip connectors ‘legs’ that serve as I/O pins remain, as does the 0.1” header socket. “This year has shown our reliance on connected technology — with CodeBug Connect we wanted to make this technology accessible so everyone can build their own IoT devices and no one is left behind. The technology in […]
