Ender 3 Pro 3D printer in late 2020 – Build and first prints

Karl here. How does the Ender 3 Pro 3D printer stand up in late 2020? The short answer is pretty well. With just a few minor gripes it is a solid printer. According to All3dp the Ender 3 Pro came out in September 2018. Over 2 years ago. It is the successor to the most popular 3D printer: the Ender 3. I usually don’t do any research so I won’t be influenced by other reviewers but I did in this case so I could see what the differences are between the Ender 3 and Pro versions. It has been upgraded to a Meanwell power supply. Better mainboard layout. Wider extrusion for the bed to ride on, which should make the bed more stable. If you have done any research on 3D printers I would say it is impossible not to have heard about the Ender 3. With its low price, print quality, and community support I can see why it […]

Reolink RLC-810A review – A 4K security camera with people & vehicle detection

Last week I received Reolink RLC-810A 4K smart security camera with support for people and vehicle detection. I listed the specifications and check out the content of the package of the first security camera I’ve received with artificial intelligence. That should be great to avoid all unnecessary alerts from motion detection I get from my “dumb” IP cameras. In this review, I’ll write a small guide showing how to use the camera with the Reolink app, the web interface, and check out RTSP and ONVIF support. I’ll also see if people and vehicle detection lives up to my expectations. Reolink RLC-810A Camera installation and setup As noted in the first part of the review, the camera does not come with a power adapter and does not support WiFi. So I had to find a 12V power adapter and used a 15-meter Ethernet cable to connect it to my router. Before mounting the camera, I connected it to the power and […]

Reolink RLC-810A Smart 4K PoE IP Camera Specifications and Unboxing

I have reviewed two Reolink WiFi IP cameras in recent years: Reolink Argus Eco and Reolink Argus PT. Both are powered by solar panels, and they’ve been running at home for many months, but there are many false positives, or on the contrary, sometimes the PIR sensor fails to detect people. What would solve this is built-in AI into those surveillance cameras. The good news is that Reolink RLC-810A does just that with the ability to detect persons and/or vehicles, so you would not receive a notification because some bird or insect flew in front of the camera.  I’ve just received a review sample, so I’ll part by listing the specs and features, and unboxing the package to see what the camera looks like, and check out included accessories. Reolink RLC-810A specifications Video & Audio Image Sensor – 1/2.49″ CMOS Sensor Video Resolution – 3840×2160 (8.0 Megapixels) at 25 frames/sec Lens – f=4.0mm fixed; F=2.0, with IR-cut filter Video Format […]

Kywoo Tycoon 3D Printer Unboxing and User Experience Review

Hey, Karl here. A lot of our readers know I do most, if not all of the 3D printer reviews for the site. I feel very fortunate to be able to review them. It does take quite a lot of time but sometimes a gem comes along. I was fortunate enough to be chosen to review and share with you a new printer from Kywoo. The Tycoon 3D printer ticks all the boxes I have been asking for. Easy assembly Direct Drive Linear motion (Rods and rails in this machine) Smooth filament holder Touch Screen Auto Bed leveling (Until now I didn’t know I wanted this…more on that later) Rock Solid frame There are a few shortcomings and I hope what I am sharing is addressed before the final shipment. I will go into more detail later on. As far as the physical printer I am super happy with the one exception. The rest of the critiques are user experience. […]

Tigard is an open-source FT2232H board for hardware hacking (Crowdfunding)

There is plenty of cheap 5V or 3.3V USB to TTL debug boards used to access the serial console and/or program boards, but FTDI FT2232H based Tigard open-source hardware board does much more than that as it supports multiple protocols, multiple voltages for hardware hacking & debugging. The developer explains Tigard can be used as a drop-in replacement for dozens of other hardware tools based on FTDI chips and includes native support OpenOCD, FlashROM, and more. Tigard board specifications: Main chip – FTDI FT2232HQ dual high-speed USB to multi-purpose UART/FIFO IC Primary port dedicated to UART including access to all flow control signals Secondary port shared among dedicated headers for SWD, JTAG, SPI, and I²C USB – USB 2.0 Type-C (480 Mbps) port I/Os 9-pin UART header Qwiic I2C connector 8-pin SPI & I2C header 8-pin JTAG header 10-pin Cortex debug header 14-pin logic analyzer (LA) header to observe device-level signals Directional level-shifters for 1.8 to 5.5 V operation Misc […]

Raspberry Pi 400 Keyboard PC Review and Benchmarks vs Raspberry Pi 4

Raspberry Pi 400 keyboard computer with Broadcom BCM2711C0 1.8 GHz processor has just launched, and we already published a teardown of the Raspberry Pi 400 hardware to check out the cooling solution and overall hardware design. In this review, we’ll mostly focus on Raspberry Pi 400 and Raspberry Pi 4 differences, since both devices mostly rely on the same chips. After checking the different features, we’ll run Thomas Kaiser’s “SBC Bench” script to test thermal cooling and benchmark both RPi hardware platforms. Raspberry Pi 400 vs Raspberry Pi 4 Model B Features Since under the hood, the two platforms are very similar, we’ll highlight the difference as shown in the table below courtesy of Cytron. Price is not shown in the table above, but Raspberry Pi 400 costs $70, while Raspberry Pi 4 with 4GB goes for $55. That’s $15 extra for a keyboard, case, and cooling solution, so the price is very attractive. Stock performance is a little higher […]

Testing PTFE Tube for 3D Printing

Karl here. I’m back with a short article on some testing that I did on PTFE tube. When I received the Sovol SV02 3D printer it came with some baby blue replacement PTFE tube. It came preinstalled with the regular white stuff that most Bowden style printers come with. I have also been thinking about different ways to use the Retraction Calibration Tool I created. I recommend reading it first to get grounded on what this tool does before going further. I have always heard that Capricorn brand is the best so I purchased some on Amazon. I will test 3 kinds. Generic white, Baby blue Sovol, and Capricorn XS tubing. (Now that I am finding the links to add to the article I see that it is through the Sovol Amazon store. This is just a coincidence.) For the uninitiated, this little tube plays an important role in 3D printing. It provides a filament path from an extruder to […]
