How to Use 3G and GPS on Raspberry Pi with ThaiEasyElec 3G HAT Expansion Board

Venus Supply is an embedded systems company based in Bangkok, Thailand that sells products through their ThaiEasyElec website/brand, as well as a act as a local distributor for popular DIY electronics items. I previously tested their ESPino32 ESP32 board, and the company has now send me another of their new product called “3G HAT Expansion for Raspberry Pi” and based on Quectel UC20-G that support 3G and GPS/GLONASS connectivity globally, meaning it should work in any country with 2G or 3G coverage. After listing the specifications, going through unboxing and assembly with a Raspberry Pi 2/3 board, I’ll write some quick start guide to show what I had to do to use GPS and connect to 3G with a Hologram SIM card. 3G HAT Expansion for Raspberry Pi Specifications Quectel UC20-G wireless module supporting Cellular 3G – UMTS @ 800/850/900/1900/2100 MHz 2G – GSM @ 850/900/1800/1900 MHz Data – HSPA+ […]

Vorke V1 Plus Celeron J3455 Mini PC Review with Windows and Ubuntu

Most Intel based mini PCs use processors classified as ‘Mobile’ as these have lower thermal design power (TDP) ratings which is the maximum amount of heat generated by the processor: However, the new Vorke V1 Plus has incorporated a ‘Desktop’ processor namely the Intel Celeron J3455. On paper this processor looks like it should perform similar to the Intel Pentium N4200 processor but with a tradeoff between being a cheaper processor to purchase but more expensive to run due to the increased power requirements. Geekbuying provided a Vorke V1 Plus for review so let’s start by taking a look at the physical characteristics. The device comes in a plain box and was supplied with the ‘right AC Adapter’ for my country. The first observation is that it is quite a large device. At just over 6” square (153mm) and nearly 1.5” tall (38mm) it is the biggest mini PC I’ve […]

Getting Started with IkaScope WiFi Pen-Oscilloscope, and ScanaQuad SQ50 USB Logic Analyzer & Signal Generator

A couple of weeks ago, I received IkaScope WS200 pen-like WiFi oscilloscope, as well as ScanaQuad SQ50 USB logic analyzer & signal generator, and I’ve already checked out the hardware both both in a aforelinked unboxing post. I had also very shortly tried IkaScope with GOLE 10 mini PC, but just to showcase potential use case for a Windows 10 mini PC with an inclined touchscreen display. But at the time I did not really a proper measurement, as it was more to test the mini PC than the oscilloscope itself. I’ve now had time to test IkaScope desktop program and mobile app in respectively Ubuntu 16.04 and Android 8.0.0, as well as ScanaStudio for ScanaQuad USB device using Ubuntu 16.04 only, since there’s no mobile version of the program. While I’ll focus on Ubuntu and Android, most of the instructions will be valid for Window 10 and Mac OS X […]

HE3D K280 Delta 3D Printer Review – Part 2: Upgrades, Calibration, and More 3D Prints

Karl here with part 2 of my experiences with the K280. In the first part of HE3D K280 3D printer review, I spoke about some of the challenges with the K280 getting it calibrated and getting Marlin to work and the initial build. In this part, we are going to look at the new effector, cooling solution I designed, calibration, and general use. If you purchase a machine now you get an injected molded effector and 2 24v cooling fans which HE3D sent over after they saw my initial review. If you purchased a kit before they started including these parts you can pick them up here to upgrade. I would like to point out that this is my first Delta printer. I don’t want to really call this a review but a way to show my experiences. First things first If you purchase this kit I urge you to […]

Getting Started with TinyLIDAR Time-of-Flight Sensor on Arduino and Raspberry Pi

TinyLIDAR is an inexpensive and compact board based on STMicro VL53L0X Time-of-Flight (ToF) ranging sensor that allows you to measure distance up to 2 meters using infrared signals, and with up to 60 Hz. Contrary to most other VL53L0X boards, it also includes an STM32L0 micro-controller that takes care of most of the processing, frees up resource on your host board (e.g. Arduino UNO), and should be easier to control thanks to I2C commands. The project was successfully funded on Indiegogo by close to 600 backers, and the company contacted me to provided a sample of the board, which I have now received, and tested with Arduino (Leonardo), and Raspberry Pi (2). TinyLIDAR Unboxing I was expecting a single board, but instead I received a bubble envelop with five small zipped packages. Opening them up revealed three TinyLIDAR boards, the corresponding Grove to jumper cables, and a bracket PCB for […]

Intel Compute Cards Review – Windows 10 and Ubuntu 17.04 on CD1C64GK, CD1P64GK and CD1M3128MK

The Intel Compute Stick revolutionized the mini PC market through the introduction of x86 based processors making Windows available as an OS option. However, for Intel the biggest target market turned out to be business rather than consumer with digital signage being a key user. As a result Intel have responded with the introduction of the Intel Compute Card. So far they have released four versions of card: and they they differ from compute sticks by no longer being standalone mini PCs but dependent on a dock or host device. The card itself is relatively small with a footprint slightly larger than a standard credit card: and is distinguished by the back being printed with details about the card including the model: The lack of emphasis on the consumer market is also evident in the rather unobtrusive plain packaging: On the end that inserts into the dock or host device […]

Pandora’s Box 5S Arcade Game Console – Teardown and Mini Review

Last year – and even in 2016 – , there was a fair amount of new retro gaming news, with products such a Nintendo SNES Classic Edition or GameShell Portable Retro console, as well as community supported firmware such as RetrOrangePi 4.0. GearBest asked me if I wanted to review something a little different: Pandora’s Box 5S (aka Pandora’s Key 5S) arcade game console with 999 games most (all?) designed for two players. This looked fun, and I was particularly interesting in checking out the hardware design, and hacking potential, e.g. if there could be a way to replace the board or firmware with your own. So in the review, I’ll focus mostly on the teardown, before shortly testing out the system and a few games. Pandora’s Box 5S Unboxing The device comes ins a large package (~70 x 24 x 16cm), so I’m surprised customs did not ask any […]

Getting Started with ANAVI Light pHat Starter Kit with RGB LED Strip, Light Sensor

ANAVI Light pHAT is an expansion board best suited for Raspberry Pi Zero (W/WH) boards, but also working with any other Raspberry Pi boards with a 40-pin header, that can control a 12V RGB LED strip and sensors. The project’s crowdfunding has just been successfully completed on CrowdSupply with 82 pledges, but you can still pre-order the board or kits for $25 and up. The developer – Leon ANAVI – had sent me a starter kit a little while ago, and this week-end I had time to test the basic functionalities of the board. The package includes the pHAT board itself, a one meter RGB LED strip, an I2C sensor, and some stickers. The sensor is based on BH1750 ambient light intensity sensor. The light pHAT boards include a 4-pin 12V/RGB blue terminal, EEPROM, three I2C connecter, a 3.3V UART connector to access the serial console for debugging / running […]
