YouTube Streams 1 & 2 Update, Plus Quick Fix for Uneven X Gantry

3D-Printer-X-Gantry-Fix

Hey Karl here with an update on the YouTube Live streams from last week. Live Streams Update The 1st stream went about as well as I expected….Not very well. I was really nervous and I broke the live link that was posted on here at the last minute. My whole reasoning for the Livestream was to show the processes in real time and not do too much footwork ahead of time. On the first one I was planning on migrating from Marlin 1.1.6 to Marlin 1.1.8 but I had already done lol… So I ended up migrating to the bugfix branch which presented additional challenges. Overall it was successful and I hope I conveyed the process. I was able to get it to print but I ended up going back to 1.1.8 due to some error in the bugfix branch that caused weird jittery movement. I will in the future prepare more. 😀 Second was better but not without glitches. …

Dual Display Laptop Made Possible with DUO Add-on Display (Crowdfunding)

DUO Dual Display Laptop

I’m using a dual monitor setup at home since it’s just more convenient and increases productivity, but when I’m on the go, I have to revert to the single screen on my laptop. The guys at Mobile Pixels decided it was not good enough, and worked on providing a solution that allows you to take that dual display setup on the go. This gave birth to DUO, a screen that attaches to the back of your laptop, and that you can slide to the left or right of your laptop’s screen to add another display whether you may happen to be. DUO display specifications: Display Size & Resolution – 12.5″, 1920×1080 pixels Rotation – 270º full rotation, 180° presentation mode Connection – USB type C for power and video signal Power Consumption – 1.6 Watts; 0.3W in “rest mode”. Dimensions – 32.5 x 21.8 x 1.2 cm (ABS plastic) Weight – 680 grams A magnetic mounting system lets you attach …

4G LTE TV Box Battery SIM Card

In some countries, especially in the Middle Easy and Africa, 4G LTE is a popular way of getting broadband Internet, and in the past we covered several 4G LTE TV boxes running Android such as WeTek Hyperion,  SDMC DV8230-AP LTE, or Geniatech ATV329. Shenzhen Tomato now offers another options with their “Onenuts 4G-LTE Android OTT Set-Top Box” powered by Amlogic S905X processor, and that happens to come with a compartment for optional batteries.

$10 H801 WiFi RGB LED Controller Supports Sonoff-Tasmota Open Source Firmware

H801 WiFi LED Controller

This week-end, I played with ANAVI Light Controller, an open source hardware solution based on ESP8266 used control 12V RGB LED strips. The board has the advantage of being open source with KiCad schematics, Arduino firmware, and HTML5 server program available, so easy to get started and modify the features as you see fit, and it also supports external I2C sensors via three headers. That’s a low volume project made in Eastern Europe and as a result the board costs $25, so I was shortly made aware there were cheaper solution, and if you are ready to mess around a little bit, H801 WiFi controller appears to be one of the most interesting solution as it sells for under $10 shipped on Aliexpress or eBay, and is officially supported by Sonoff-Tasmota open source firmware. H801 specifications: Connectivity – 802.11 b/g/n WiFi (2.4GHz) with about 10 meter range Output – 5x PWM (R, G, B, W1, W2) each up to 4A, …

ODROID-GO is an Arduino Compatible, ESP32 based Portable Gaming Console Kit

ODROID-GO

When I first saw Hardkernel made ODROID-GO portable gaming console, I immediately thought they did a Linux device ala PocketCHIP, since so far the company has only designed Android & Linux development board.

Digitize Handwritten Notes with a $10 LCD Writing Pad and CamScanner App

Despite writing about high-tech technology with processors, software, IoT, artificial intelligence news everyday, I’m still very much a pen and paper kind of guy when it comes to taking notes. But this morning, I figured out it’s possible to digitize your notes on the cheap without having to use actual ink and paper, as 8.5″ digital LCD writing pads now cost as little as $10 shipped, and although those are pretty dumb devices with just an erase button and no connectivity nor storage, you can “scan” your notes using CamScanner app for Android and iOS. Specifications for the $10 model: 8.5″ LCD display with 25%-30% reflective ratio Pen Input pressure – 10-20g Power Supply – CR2016 button battery (included) Dimensions – 228 x 147 x 5mm (ABS plastic) Weight – About 110g This will reduce the amount of paper you use and store, and possibly have a positive impact of the environment, although estimating the latter is always harder than …
