Campaign Ending Soon

Hi all.

Thanks to all of you who have supported the Haasoscope - we’re 135% funded, with just 1 day left in the campaign! If you haven’t got one yet, you still have time… prices will go up a bit once the campaign closes.

I’ve continued to work towards the final prototype hardware. To speed up the development cycle, and cut costs, I ordered some plain PCBs, which arrive in just 1 week, for $50 for 10 boards, as opposed to ~4 weeks for a fully assembled board at $150 per board! The downside is I have to assemble the board myself, which means soldering on all the little resistors and capacitors, and even the 0.4mm pitch 144-pin FPGA, by hand! This is not for the faint of heart. In case you’d like to see what’s involved, here’s a video:

It took me about 3 hours to get this far:

You can see some new features in the prototype above. There’s now a built-in serial -> USB adapter, so it just plugs into your computer directly! I also adjusted the digital IO pinouts in the empty top part of the board so you can plug on the popular USB2 board directly.

Once I finish tweaking things a bit on this prototype, I’ll ask the assembly house for a couple final prototypes, and then assuming those look good, I’ll order the final production of 200 Haasoscopes!

$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.
