Hantek PSO2020 is a $53 USB Oscilloscope Pen

I previously covered IkaScope & Aeroscope oscilloscope probes that are both portable and connect wirelessly to your mobile device or computer over respectively WiFi or Bluetooth. The former has slightly better specifications and sells for 300 Euros, while the latter goes for $200 US with 20 MHz bandwidth and 100 MSps capabilities. Several people mentioned it was more expensive than they were prepare to pay, but I’ve been informed about another portable solution: Hantek PSO2020 oscilloscope pen with about the same key specifications as Aeroscope 100A, except it relies on a USB port instead of a wireless connection. This also means it does not need a battery, and sells for much less at $53.20 including shipping. Hantek PSO2020 specifications: Analog Bandwidth  – 20 MHz Sample Rate – 96 MSps Host Interface – USB 2.0 port Input Range – +/-50 V range Input Sensitivity – 20mV/div to 50V/div Offset Range – […]

Fedora 26 Supports Single “Unified” OS Images for Multiple ARM Platforms

The decision to use device tree in Linux occurred several years ago, after Linus Torvalds complained that Linux on ARM was a mess, with the ultimate goal of providing a unified ARM kernel for all hardware. Most machine specific board files in arch/arm/mach-xxx/ are now gone from the Linux kernel, being replaced by device tree files, and in many case you simply need to replace the DTB (Device Tree Binary) file from an operating system to run on different hardware platforms. However, this is not always that easy as U-boot still often differ between boards / devices, so it’s quite frequent to distribute different firmware / OS images per board. Fedora has taken another approach, as the developers are instead distributing a single Fedora 26 OS ARMv7 image, together with an installation script. Images for 64-bit ARM (Aarch64) are a little different since they are designed for SBSA compliant servers, so […]

How ARM Nerfed NEON Permute Instructions in ARMv8

This is a guest post by blu about an issue he found with a specific instruction in ARMv8 NEON. He previously wrote an article about OpenGL ES development on Ubuntu Touch, and one or two other posts. This is not a happy-ending story. But as with most unhappy-ending stories, this is a story with certain moral for the reader. So read on if you appreciate a good moral. Once upon a time there was a very well-devised SIMD instruction set. Its name was NEON, or formally — ARM Advanced SIMD — ASIMD for short (most people still called it NEON). It was so nice, that veteran coders versed in multiple SIMD ISAs often wished other SIMD ISAs were more like NEON. NEON had originated as part of the larger ARM ISA version 7, or ARMv7, for short. After much success in the mobile and embedded domains, ARMv7 was superseded by […]

DLP LightCrafter Display 2000 EVM Adds a Pico Projector to BeagleBone Black for $99

Back in 2012, Texas Instruments introduced DLP LightCrafter pico projector evaluation module powered by a TMS320DM365 ARM9 processor @ 300 MHz running embedded Linux, and selling for $599. Since then, we have seen many products including projectors based on DLP technology such as standalone tiny projectors, Windows mini PCs, Android TV boxes, tablets, an even light bulbs. However, so far I can’t remember seeing any easy way to easily integrate DLP projector with the cheap ARM Linux development boards available today. Texas Instruments has now filled that void with DLP LightCrafter Display 2000 EVM that adds a pico-projector to BeagleBone Black (or Green) based on the new 0.2″ DLP2000 DMD (Digital Mirror Device) chip. The board is comprised of two subsystems: Light engine (top) with the optics, red, green, and blue LEDs, and the 640 × 360 (nHD) DLP2000 DMD configured to deliver around 20 lumens by default (this can […]

Silicon Power C50 3-in-1 USB Flash Drive Comes with micro USB, USB Type C, and USB Type A Ports

USB flash drives are convenient ways to carry data around, and load on other computers. They are usually based on USB type A found on computers, laptops and even TVs, , but if you plan to connect it to your smartphone or tablet, which may only comes with micro USB or USB type C port, you’ll need an OTG adapter to connect the USB flash drive. It works, but if you don’t like to look for the adapter each time you can want to connect, Silicon Power C50 USB flash drive offers a solution as it includes all three types of connectors. Sorry no mini USB port 🙂 Specifications of Silicon Power OTG Mobile C50 flash drive: Capacity – 32GB, 64GB, or 128GB Interfaces – USB Type-A (USB3.1 Gen 1), Micro-B (USB 2.0), Type-C (USB3.1 Gen 1) Dimensions – 41.7 x 7.0 x 15.0mm Weight – 5.2g Operating Temperature – […]

GIGABYTE GA-SBCAP3350 Celeron N3350 Single Computer Computer Offers Upgradeable Memory and Storage

The other day I wrote about MeLE PCG35 Apo mini PC which comes with soldered RAM and eMMC flash, and one person commented about having a model with more than 4GB RAM, but I explained it would  not be cost-effective to add more RAM for low cost Windows 10 mini PCs since they would not qualify for Microsoft discount, and it would significantly add to the price. So Microsoft has a big impact on this market segment, and even if you’re going to run Ubuntu or other Linux distributions, those requirements indirectly affect your choice of hardware.  One solution is to buy barebone mini PC, or at least with upgradeable RAM and storage, but there aren’t that many with an Apollo Lake processor. Intel NUC6CAYS NUC or GIGABYTE GB-BPCE-3350 are options, and on the Chinese side, you could consider Voyo V1 VMac Mini. AFAIK, none of those options are fanless, […]
