La Frite Amlogic S805X Board Runs Mainline Linux, Goes for $5 and Up (Crowdfunding)

Libre Computer first started with their AML-S905X-CC (aka Le Potato) board powered by Amlogic S905X processor last year, and they’ve since then launched several other boards based on Allwinner or Rockchip processor. But their latest “La Frite” board – also known as AML-S805X-AC – is an even lower cost version of the “Le Potato” board, with an Amlogic S805X processor limited to 1080p60 output and video decoding, a smaller footprint based on the one for Raspberry Pi Model A+, and price starting at just $5 on Kickstarter. AML-S805X-AC “La Frite” board specifications: SoC – Amlogic S805X quad core ARM Cortex-A53 processor @ 1.2 GHz with penta core ARM Mali-450MP GPU @ 650 MHz, and Amlogic Video Engine 10 System Memory – 512 MB or 1GB DDR4 @ 2400 MHz Storage –   eMMC module connector, 128 Mb SPI NOR flash Video & Audio Output – HDMI 2.0 port Video Codecs Decoding […]

Genmitsu CNC 3018-PRO CNC Router Review – Part 1: Build & First Etches

Hey Karl here. Today we are going to look at something a little different. I am writing about my experiences with building Genmitsu 3018 CNC router upgraded version provided by Sainsmart for this review. While waiting on the unit to arrive I did some research and found that there are several different versions on the market labeled CNC xxxx. The xxxx represent the build volume in the x and y. So the one I was sent has a 300x180mm build volume. The 3018 is called upgraded because the new mounting for the X and Y rods and lead screws. On the previous version these had to be mounted and manually aligned which from what I read can be a pain. Building Genmitsu CNC 3018-PRO CNC Router The build went very well. The 3018 user manual was mostly pictures but they called out anything that might be questionable. I had been […]

How to Make a Low Cost DIY SD Card Duplicator

If you have to duplicate many SD cards for example to boot Raspbian on multiple Raspberry Pi board, one option is buy one of those SD card duplicators, but the problem is that they are not really cheap, for example the Systor 1-to-7 cards model sells for $540. Bob Brown, a retired senior lecturer, is now teaching K-12 students how to get started with Raspberry Pi boards, and must prepare bootable SD cards for his class. In order to save time, a duplicator would have been nice, but the price is too high, so instead he went with a DIY solution. You’ll first need some hardware, including a powered USB hub with the number of cards you want to duplicate, and corresponding SD card reader, and a larger micro SD card to hold Raspbian and/or other operating systems (optional, only for Raspberry Pi based duplicator). Mr. Brown made a 10-port […]

Seeed Studio Introduces 1 to 8 Channels Grove I2C Solid State Relay Modules

I’ve been playing with products or boards with AC relays for a while, but I never really cared to check about different types of relay. So far, all platforms I tested came with largish blue or black boxes which are SPDT electro-mechanical relays. But as I browsed through Seeed Studio, I found some weirdly-shaped relay modules, much thinner than usual, and fairly more expensive. The main difference is that those are solid state relays, and the boards also include a grove connector that allows microcontrollers or other boards to control the relay over a simple I2C connection. The modules are available in 1-channel, 2-channel, 4-channel, and 8-channel  versions with the following specifications: MCU – STMicro STM32F030F4P6 Arm Cortex-M0 micro-controller Relay –  Omron G3MC202P module Input Voltage – 4~6V (Rated Input Voltage: 5V) Load Voltage Range – 75 to 264 VAC 50/60 Hz Rated Load Voltage –  100 to 240 VAC 50/60 […]

TableX Arm Linux Tablet Runs Armbian Ubuntu, To Launch for 89 Euros

If you want an Arm Linux laptop, you have already some choices with products such as Pine64 Pinebook,  or Olimex TERES-I open source hardware laptop,  but if instead you’d rather do without keyboard, and get an Arm Linux tablet, choices are much more limited, if any at all. Back in 2012, Allwinner A10 based PengPod 700 & 1000 tablets were available for the company has since folded, and this year, RasPad case launched to allow you to build your own thick tablet with a Raspberry Pi 3 (B+). However, if you want to normal looking tablet, your best option right now is to get an Android tablet and mess around to install Linux on it. That’s not for everyone, and the good news is that what looks like a proper – albeit low-end – Arm Linux tablet is coming to market soon with TableX. TableX preliminary hardware specifications: SoC – […]
