Haasoscope is funded!

Thanks to everyone who’s helped make Haasoscope a successful project! There’s still some time left to get Haasoscope stuff at the campaign prices. Once the campaign closes, I’ll make the order for the first production batch!

As far as development, I’ve continued to add functionality to the firmware and software. It’s pretty easy, and you’ll be able to do it soon too (open source everything!). Today I added a “runt trigger” - the ability to trigger on an unusual signal that doesn’t occur often. In this case, I added a trigger that only fires when the signal is above threshold 1, but below threshold 2, for a given amount of time. This lets me capture events like this:

(Please excuse the noise - this is an old prototype board!)

In other news, the latest prototype just arrived in the mail today - I look forward to testing it out!

Best, Andy.

Product Choices

$119

Your very own Haasoscope!

A fully assembled Haasoscope, preloaded with firmware and ready for data-taking! You also might want to grab a USB-serial adapter (for interfacing to a computer) and/or a USB-blaster (for reprogramming the firmware).


$9

USB-blaster

This lets you reprogram the Haasoscope FPGA firmware from either Windows or Linux using the free Altera Quartus II software via the JTAG connector.


$9

A Cool Screen!

This is a 0.96" 128X64 pixel white OLED screen. It communicates with the Haasoscope over an SPI interface, and can show ADC data from a selected channel, or whatever you tell it to! It can plug directly into the header above the FPGA.


$16

Oscilloscope Probes

Two passive 100 MHz bandwidth oscilloscope probes for connecting to Haasoscope 100 MHz ADC inputs using BNC.


$15

High-speed USB Readout Board

In case 1.5 Mb/s is not enough bandwidth for you, grab one of these boards and have high-speed USB2 output from a Haasoscope! Using just 8+2 digital outputs on the Haasoscope, you can get about 4 MB/s, about 20x faster than serial, and still use the same python readout code. It's supported in the stock firmware too! Using 8+4 digital outputs, you could in theory even get up to 40 MB/s using C++ readout code and the free FTDI USB libraries.
