SainSmart DS802 Review – A Dual Channel Virtual PC Oscilloscope

DS802 Oscilloscope Arduino

Hey Karl here. Today we’re going to look at the SainSmart DS802 Dual-channel oscilloscope. I have always wanted to have an oscilloscope and add it to my tools. When SainSmart asked to review the DS802, I was pretty excited. I can get my nerd on and troubleshoot all kinds of things. A couple weeks later it arrives and my anxiety kicks in. How the heck do I review an oscilloscope. I used an oscilloscope in high school in a class called principles of technology. But we never really went into much depth and only looked at the signals generated by a signal generator. I understand the basics. This is written from a perspective of a complete noob. SainSmart DS802 Specs Pulled directly from Sainsmarts website: Channels: 2 Analog channels Interface: USB 2.0 Output: 1k HZ amplitude 1.5V, 50% duty cycle square wave signal Maximum sampling rate: 80 MSps per channel Vertical resolution: 8 bit Voltage range: ±5v, expandable to ±50v …

PSLab Electronics Lab Board is Now Available for $65

PSLab Electronics Lab

Pocket Science Lab (PSLab) is an open source hardware USB board that aims to bring electronics labs to the masses, as it can act as an oscilloscope, voltmeter, programmable voltage and current source, logic analyzer, or signal generator when connected to a PC or mobile phone. This is not professional equipment, and instead designed for STEM education. When we first covered the board in August, it was still in development, but I’ve just found it is now listed and in stock on Seeed Studio for $64.90. FOSSASIA and OpnTec are the organization behind the board’s development. Here’s a reminder of PSLab board main specifications: MCU – Microchip PIC24EP256GP204 16-bit microcontroller @ up to 70 MHz with 32KB SRAM, 256KB flash Wireless Connectivity Footprint for ESP8266 module (ESP-12E) for 802.11 b/g/n WiFi (on bottom of board) Bluetooth extension slot 4-Channel, up to 2MSPS Oscilloscope 12-bit Voltmeter. Programmable gain. Input ranges from +/-10mV to +/-16V 3x 12-bit Programmable voltage sources: +/-3.3V,+/-5V,0-3V 12-bit …

Pocket Science Lab (PSLab) is an Open Source Hardware Electronics Lab

Last Saturday I created a virtual schedule for the Embedded Linux Conference Europe 2018 where I listed some of the sessions relevant to myself and hopefully regular readers of CNX Software, but due to scheduling conflicts one talk did not make it to the list: “Pocket Science Lab – An Open Source Hardware for Electronics Teaching & Learning” by FOSSASIA. The project is also referred to as PSLab, and aims to  “create an Open Source hardware device that can be used for experiments by teachers, students, and citizen scientists to learn and teach electronics”. It looks interesting enough so let’s have a closer look. The project is inspired by the earlier expEYES project that combines with Raspberry Pi or other Linux platform to create an electronic labs, and the work by the Open Science Hardware community. PSLab key features and specifications: MCU – Microchip PIC24EP256GP204 16-bit microcontroller @ up to 70 MHz with 32KB SRAM, 256KB flash Wireless Connectivity – …

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 for the desktop programs, and iOS for the mobile app. …

Ikascope WS200 Oscilloscope and ScanaQuad SQ50 Logic Analyzer & Pattern Generator Review – Part 1: Unboxing

IkaScope WS200 WiFi oscilloscope fits in your hand like a pen, and works with devices running desktop or mobile operating systems, namely Windows, Linux, Mac OS X, Android, and iOS. I covered the tool last September, and IkaLogic – the French startup behind the project –  has now sent me a sample for review, as well as their ScanaQuad SQ50 4-channel logic analyzer and pattern generator. Since I had never checked out the latter, I’ve decided to start the review with an unboxing post, before reporting my experience actually using the tools next month. IkaScope WS200 Wireless Oscilloscope Probe The oscilloscope comes with a ground clip, a micro USB to USB cable for charging, and a getting started guide with a QR code to download IkaScope program or app. Once you open it, it really looks like an over-sized Stabilo highlighter. The only needed hardware connection needs is the ground clip, and micro USB port to charge the battery. The …

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 – +/- 20V to +/- 40V offset Input Impedance – 1MΩ …

IkaScope WiFi Oscilloscope Probe Works with Windows, Linux, Mac OS X, Android and iOS

Last year, I wrote about Aeroscope, a portable Bluetooth oscilloscope that looks somewhat like a Stabilo Boss highlighter pen, and sends measurements over the air directly to your Android and iOS tablet or smartphone. It was introduced through a crowdfunding campaign which eventually failed, but Aeroscope can now be purchased for $199 on Amazon US or their own website. If you’d prefer WiFi over Bluetooth, and would like something that also works on Windows, Linux, and/or Mac OS X, IKALOGIC has just launched IkaScope WiFi oscilloscope probe compatible with all popular mobile and desktop operating systems. IkaScope WS200 specifications: Analog Bandwidth  – 30 MHz @ -3dB Sample Rate – 200 MSps Connectivity – 802.11 b/g/n/e/i WiFi @ 2.4 GHz configurable as access point or station Input Range – +/-40 V range CAT1 Offset Range – +/- 20V to +/- 40V offset Input Impedance – 10MΩ || 14pF Input Contact – ProbeClick intelligent probe tip that will only start measurements upon …
