No updates from krtkl since April 10, 2018. I don’t know if I even care when it arrives. There’s no way I’d give them anymore money if I was to develop a product using the snickerdoodle black. Time to look more for alternate platforms.

Well, there’s been an update from krtkl, but snickerdoodle black wasn’t mentioned. I guess no news is bad news. They mentioned the supply chain has completely broken down, they just can’t get parts. Not that that helps the backers. They still haven’t gotten to the point that they are making piSmashers. So the snickerdoodle black wouldn’t do me too much good. Maybe if I could get the software I could start developing something for the vapor hardware.

Well, there haven’t been any updates from krtkl about progress on shipments, so I’ve started to look around for another vendor that supplies an SBC integrated with an FPGA for a project I want to do. Results for my search so far has yielded the SYZYGY Brain-1 at $350 which comes from a company with a little more street cred, Opal Kelly, and the Z-turn board at $119 from MYIR Tech Limited. The $99 part is a Zynq-7010 part whereas I’m interested in the more powerful Zynq-7020 at $119. I sent off an inquiry to the company, but so far I haven’t heard back from them.

Well. still waiting for delivery. I contacted Krtkl and told them it was a waste to ship me the snickerdoodle black without the pi smasher. So maybe they’ll just ship them both a the same time.

Here’s their video of the snickerdoodle:

Well, I’ve got another update. Snickerdoodle black is now due December 28, 2017 and the piSmasher SBC is now due March 8, 2018. Just another disappointment. I wonder if it was just an overly ambitious project. There’s been a number of schedule delays .Krtkl does keep us updated on the latest delay, I’ll give them that. I’ll be interesting to work with a Xilinx processor after being away for about 15 years. Yeah, 2003 was the last time I touched one of their processors.

The one positive thing is that if I ordered the snickerdoodle black now it’s up to $195 and the piSmasher SBC board is up to $195, but I’m not sure whether what I bought are the same devices. It’s taken so long to get these, I don’t even know what I’m going to use them for, because the project I was going to use them for has been shelved.
