Creality Ender-3 S1 Pro review – Part 2: Engraving and 3D printing

Creality Ender 3 S1 Pro 3D Printer laser Engraver

Earlier this year, I received the Creality Ender-3 S1 Pro 2-in-1 3D printer & laser engraver and in the first part of the review, I showed the package content and how to assemble the system either to use it as a 3D printer or a laser engraver, but didn’t start it at the time. I’ve now had time to play with both laser engraving (less luck with cutting) and 3D printing, so I’ll report my experience in the second part of the review. Creality Ender-3 S1 Pro laser engraving Since in the last part of the review I had the 10W laser module installed on the 3D printer, I decided to start the testing with laser engraving and cutting. Contrary to the TwoTrees TS2 laser engraver I reviewed last year, the Creality Ender-3D S1 Pro laser engraving kit does not support autofocus, so I used the provided multi-level fixed-focus bar […]

BIGTREETECH Pad 7 7-inch 3D printer control display runs Klipper on Allwinner H616 SoM or Raspberry Pi CM4

BIGTREETECH Pad 7 Settings

Yesterday, I wrote about the BTT Pi V1.2 Allwinner H616 SBC designed for 3D printers, but also mentioned I had received the Pad 7 from BIGTREETECH which is a software-compatible, but more complete solution with a 7-inch display and an Allwinner H616-powered CB1 system-on-module compatible with the Raspberry Pi CM4. The BIGTREETECH Pad 7 should be more convenient to use with its integrated 7-inch touchscreen display, and if you ever decided you didn’t need it to control your 3D printer anymore, it could always be used as a small Linux computer running Raspberry Pi OS or another operating system. BIGTREETECH Pad 7 specifications: Supported modules BIGTREETECH CB1 v2.2 (included in the kit) – Allwinner H616 quad-core Cortex-A53 CPU with Mali-G31 MP2 GPU, 1GB RAM, 802.11 b/g/n WiFi 4 Raspberry Pi CM4 module with Broadcom BCM2711 quad-core Cortex-A72 CPU with VideoCore IV GPU, 1 to 8GB RAM, 0 to 32GB eMMC […]

Using Pico:ed V2 board as a replacement for BBC Micro:bit

Pico:ed V2 BBC Micro:bit Alternative

We’ve received a sample of the Pico:ed V2 board developed by ELECFREAKS and will show how to use it as a replacement for the BBC micro:bit in a project using CircuitPython. We’ve already covered the board in detail with specifications, block diagram, and pinout diagram before, and it’s basically a Raspberry Pi Pico RP2040 board with BBC Micro:bit form factor including a 17×7 Dot Matrix LED display, some buttons, a buzzer, but no wireless connectivity, relying only on USB instead. CircuitPython firmware installation on the Pico:ed V2 board The board supports C/C++, MicroPython, and CircuitPython programming languages, and for this review, we’ve decided to download the CircuitPython UF2 firmware. Press and hold the BOOTSEL button after having downloaded the firmware file… … and connect the board to your computer using a USB cable before releasing the BOOSEL button on the Pico:ed V2 board, which should then show up as the […]

SONOFF iHost Review – A future-proof Smart Home Hub for local control

SONOFF iHost review

ITEAD has sent us a Sonoff iHost Smart Home Hub for review, and this device seems to be what many SONOFF fans have been waiting for, especially in terms of local control. meaning it can work without an Internet connection. SONOFF is known for its durable devices and good interoperability, but they are still catching up with other companies in terms of local control. Finally, the iHost Smart Home Hub fills the gap. In addition to local control, it also comes with privacy features as data stay local. SONOFF plans to expand its ecosystem by including devices from other brands compliant with standards such as Zigbee 3.0. Furthermore, the iHost Smart Home Hub is more like a platform than just a product, as it has add-ons to add more capability over time. In the future, it can be expanded to support the new “Matter” standard, similar to Home Assistant. The […]
