Project update 9 of 21
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!
