CrowView adds a 14-inch portable monitor to your laptop for $115 and up (Crowdfunding)

CrowView 14 inch laptop monitor extender

Elecrow CrowView is a lightweight 14-inch portable monitor designed to be attached to your laptop adding a secondary monitor to it through a clamping structure that works with laptops having a 13-inch to 16.5-inch display. We’ve seen this type of laptop monitor extension for years, and you’ll find various models on Amazon. But the Elecrow is now offering the CrowView at a significantly lower price than competitors especially if you pledge $114.90 for the super early bird reward on Kickstarter. The regular price ($179) can still be interesting as in this price range you’d usually get an 11-inch or 12-inch display. CrowView specifications: 14-inch IPS display with 1920×1080 resolution, 60 Hz refresh rate, 400 nit brightness Compatible with 13-inch to 16.5-inch laptops with 4 to 8mm thick displays thanks to a telescopic snap 230° hinge enabling face-to-face mode.

KOKONI SOTA 3D printer handles 600mm/s prints, 7-color printing (Crowdfunding)

KOKONI SOTA 3D printer

KOKONI SOTA 3D printer with an inverted design (the printing head is under the hotbed) that supports printing speeds of up to 600mm/s, as well as 7-color printing through a filament tower adding support for 5 extra filament rolls. The upside-down design was made to move motors and rails to the bottom base of the printer to lower the center of gravity and help improve stability, reduce the vibration to virtually nothing, and enable the faster printing speed. KOKONI also says the SOTA 3D printer offers 0.1mm accuracy thanks to AI radar detection and error compensation and operates relatively silently at 30dB one meter from the 3D printer. KOKONI SOTA specifications: Printing size – 200 x 200 x 200 mm XY axis – Linear rail Z-axis SOTA Lite – Lead screw SOTA – High-precision ball screws Drive motor SOTA Lite – high-speed stepper motor SOTA – Closed-loop motor with magnetic […]

ESPi Ethernet & info display board comes with ESP32-S3 module or Raspberry Pi Pico W board (Crowdfunding)

ESPi board ESP32 S3 Ethernet Display Joystick

SB Components’ ESPi is a WiFi-enabled Ethernet board with a 1.14-inch information color display either coming with an ESP32-S3 WiFi and Bluetooth module or designed as a carrier board for the Raspberry Pi Pico W board. I have no idea who needs this, but the ESPi board looks cute and can be used as a 10/100Mbps Ethernet to WiFi (or BLE) gateway with a small TFT display, and there’s also a small joystick on the board to control a potential menu or user interface rendered in the display. ESPi board specifications: Module/Board (one or the other) ESP32-S3-WROOM-1 module with ESP32-S3 dual-core LX7 microprocessor @ up to 240 MHz with Vector extension for machine learning, up to 16MB flash, up to 8MB PSRAM, WiFi 4, and Bluetooth 5 with LE/Mesh Raspberry Pi Pico W board with Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 133 Mhz with 264KB RAM, 8MB SPI flash, […]

Convert your 3D printer into a metal cutting machine with an Electrical Discharge Machining kit (Crowdfunding)

Powercore EDM 3D printer kit

Rack Robotics’ Powercore is an Electrical Discharge Machining (EDM) kit that converts your existing 3D printer (or CNC router) into a machine capable of cutting high-precision and detailed metal parts. We’ve already seen 2-in-1 3D printers and laser engravers such as the Creality Ender 3 S1 Pro, but while this type of machine can usually cut plywood or engrave stainless steel, the laser is not powerful enough to cut through aluminum. The Powercore EDM kit changes that by enabling the cutting of aluminum parts up to 4mm thick, although aluminum sheets that are 1mm or thinner are recommended. But before we get into Powercore details, what is Electrical Discharge Machining exactly? Engineers Edge explains: Electrical Discharge Machining, EDM is one of the most accurate manufacturing processes available for creating complex or simple shapes and geometries within parts and assemblies. EDM works by eroding material in the path of electrical discharges […]
