Espotek Labrador is s $25 5-in-1 Lab-on-a-Board with Oscilloscope, Waveform Generator, etc… (Crowdfunding)

We’ve already seen ultra cheap (and low end) electronics lab tools like DSO138 oscilloscope kit for $23, or the $5 USB123 USBee AX logic Analyzer, but EspoTek Labrador combines 5 electronics lab equipments into a single board that claims to act as an oscilloscope, a waveform generator, a variable power supply, a logic analyzer and a multimeter for just $25. EspoTek Labrador specifications and key features: MCU – Atmel ATXMEGA32A4U 8-bit AVR MCU @ 32 MHz with 32KB flash, 4KB SRAM, and 1024 bytes EEPROM Functions 2 channels oscilloscope up to 750ksps, ~100kHz bandwidth, -20 to +20 V range 2 channels waveform generator up to 1 MSPS supporting sinusoidal, square, triangular, sawtooth, and arbitrary waveforms 4.5 to 15V power supply up to 1.5W max 2 channels logic analyzer up to 3 MSPS per channels Multimeter with voltage, intensity, resistance, and capacitance functions USB – micro USB port to connect to […]

Aeroscope is a Bluetooth 4.1 Wireless Oscilloscope Probe Using your Android Tablet or iPad for Display (Crowdfunding)

Oscilloscopes used to be rather bulky equipment, but recent full featured oscilloscopes have come down in size, and even become portable and battery operated with products such as DSO Quad. But since many of us already own Android tablets or iPads, Aeroscope wireless oscilloscope probe is quite a neat solution as it transmits images of the waveform over Bluetooth 4.1 to your tablet. Aeroscope specifications: Analog Bandwidth – 100 MHz Sample Rate – 500 M samples/second Connectivity – Bluetooth 4.1 with 200-ft range Input Range – +/-40 V DC Accuracy – +/- 3% Offset Range – +/- 40V or +/- 20V offset for 20mV/div setting Sample Memory Depth – 10k Input Impedance – 10MΩ || 12pF Resolution – 20 mV/division to 10 V/division Battery – 950 mAh battery good for 4 to 8 hours of use depending on settings Activity sensor – (for extended use) Dimensions – 118 x 30 […]

JYE Tech DSO138 is a $23 DIY Oscilloscope Kit

Back in 2012, I was pleasantly surprised when I discovered they made Digital Storage Oscilloscope (DSO) for less than $200, and today, you can find several oscilloscopes for less than $100, albeit with limited performance, such as DS201. But if you don’t need a high speed DSO and just want to have some fun, JYE Tech DSO138 is a single channel oscilloscope DIY kit that you need to assemble yourself, and sells for just $23 on Banggood, or about $30 on Aliexpress, or Ebay. DSO138 key specifications: MCU – STM32F103C8 ARM Cortex-M3 processor Display – 2.4 -inch color TFT display Analog bandwidth – 0 – 200KHz Sampling rate – 1Msps max Sensitivity – 10mV/Div – 5V/Div Sensitivity error – < 5% Vertical resolution – 12-bit Timebase – 10us/Div – 500s/Div Record length – 1024 points Input impedance : 1MΩ Maximum input voltage : 50Vpp (1:1 probe), 400Vpp (10:1 probe) Built-in […]

$359 Red Pitaya Board Combines an Oscilloscope, a Spectrum Analyser, a Waveform Generator and More

If you need to setup an electronics lab, the cost of equipment such as an oscilloscope, spectrum analyzer, can quickly add up and become expensive. There are already some attempts at low cost measurement devices such as the $35 ExpEyes Junior or pocket size digital storage oscilloscopes (~$200), but those are far from the performance achieved with regular measurement devices. Red Pitaya measurement board brings the performance level and flexibility a bit higher, and stays relatively low cost at $359, with a Linux-based solution based on Xilinx Zynq dual Cortex A9 + FPGA SoC. Hardware Specifications: SoC – Xilinx Zynq Z7010 dual core Cortex A9 CPU + FPGA System Memory – 1GB DDR2 RAM Storage – microSD card slot (For system and FPGA images, and data) Connectivity – 10/100M Ethernet USB – 2x micro USB ports (1 for power, 1 for console), and 1x USB 2.0 Host port Signals: 2x […]

$35 expEYES Junior Transforms the Raspberry Pi, Aakash2 Tablet or any Linux Powered Device into an Electronics Lab

I remember in high school in France, our class only had 2 oscilloscopes and few other electronics equipment, needless to say I did not actually get to use an oscilloscope until I went to university. It would have been nice to be able to play around with oscilloscopes, frequency generators, etc… earlier, but due to budget constraints, this was not possible. Dr Ajith Kumar, a scientist working with the Inter University Accelerator Centre of India, has spent several years working on an ultra low cost electronics lab composed of an oscilloscope and a signal generator to provide students attending schools that cannot afford regular equipments. This learning & experimentation tool is called expEYES, and a prototype was demonstrated last year with the Raspberry Pi. At the end of last year, the final version called expEYES Junior (aka expEYES 2.0) was announced, and is now available to schools and hobbyists in […]

Headless Connected Oscilloscope based on Cubieboard or Beaglebone

Warsaw ELHEP (Electronics for High Eenergy Physics Experiments) Group is currently working on MMS (Mobile Measurement System) Project. This project features what I would call a “headless connected oscilloscope”, which can be detected on the network via SSDP, send the data via Websocket, and display it on iOS, Android, or Windows Phone devices. This oscilloscope does not feature any screen, and receives/transmits data via Ethernet, Wi-Fi, or Bluetooth. The original hardware is based on three main boards: CTI-VMAX – ARM9 with Wi-Fi, Bluetooth, and Ethernet connectivity. ARM SCOPE v1.0.1 with 8 channel ADC. ARM SCOPE v1.0.2 with 4 high speed ADC (100MSPS). The ELHEP researchers have been looking at replacing CTI-VMAX with low cost boards, and after considering several options, they chose to design two versions of their oscilloscope: one based on Cubieboard, and the other on the Beaglebone. So they designed expansions boards for the Cubieboard and Beaglebone in […]
