One more go at new enclosures for the Amiga 1200. Yes, it’s a Kickstarter campaign, and we mentioned a similar the same campaign last month. The previous campaign received a little more than half of the desired funding in a 30-day campaign. The new campaign received half its funding in a week. The only difference? Now you can put a Raspberry Pi in a newly manufactured A1200 case. And they say Raspberry Pi consumerism isn’t a thing…

Cheap SLA printing service. [Ian] and Dangerous Prototypes have made a name for themselves with dirt cheap, acceptable quality PCBs. Now they’re going for custom prints on a resin machine. It’s $0.95 per gram (density is 1.3g/cc). That’s cheap.

[James Willis] built a floppy drive orchestra. There are 16 drives in this orchestra, all controlled by an FPGA. Here’s the writeup.

Here’s a video overview of a real, huge, rideable hexapod robot. ‘Wow’ is just about the only thing we got for this.

Western Digital introduced a hard drive made specifically for the Raspberry Pi. It’s a hard drive with a USB interface, and a USB cable that connects to the Pi, the drive, and a power adapter. In other news, externally powered USB hard drives exist. You can buy a 2TB drive for the price of the 1TB PiDrive. What was that thing about Raspi consumerism?

Next week is the Open Hardware Summit in Philadelphia. We’ll be there (or rather, I will). We’ll have a post on the OHS badge up on Monday. Would anyone like to go see the lady made out of soap? It’s right around the corner from the venue.

The Joys Of Shipping From China

October 15, 2014 by 45 Comments

A few months ago, news of a new PCB fab service headed up by [Ian] over at Dangerous Prototypes leaked onto the Internet. It’s extremely cheap – $14 USD for a 5cm square board with free worldwide shipping. [Ian] admits the boards aren’t the greatest quality, that’s not the point; the site’s motto is simply, ‘No bull, just crappy PCBs.’

What began as an internal website to handle all of DP’s PCB orders was now on the Internet, and orders were flying in. At first, shipping a few dozen PCBs around the globe every week was easy, but since Dirty PCBs hit the big time, customers rightfully or not, started freaking out because of the oddities of Chinese shipping and logistics companies.

[Ian] is using Espeed Post for all their shipping, and if you’ve ever ordered anything from China off of Ebay, it’s possible you’ve had something shipped through Espeed before. Because of the oddities of shipping, and the fact that Shenzhen and Hong Kong are right next to each other, even the people at Dangerous Prototypes don’t know which countries your PCBs will go through on the trip from the fab house to your front door. This has caused much consternation with DirtyPCB customers that don’t seem to realize they’re getting custom PCBs for under two dollars a board, shipped to them across the world in a week for free. Some people’s children, huh?

Things get significantly, ahem, dirtier, when Chinese holidays are taken into account. China has a lot of them, and they’re long. They’re just wrapping up the National Day holiday, 10 days in the first week of October. Everyone is backlogged, and the China/Hong Kong border is the mess of trucks seen above.

If a holiday isn’t bad enough, the new President of China is cracking down on corruption. 500 officials were fired at the largest land border with Hong Kong, due in no small part to vans full of meth and tons of counterfeit currency. Every package leaving China is inspected individually, and shipping times have exploded.

To deal with this, Dangerous Prototypes has posted a big red warning on the dirtypcb site, but experience in dealing with people on the Internet tells them this won’t be a viable solution. They’re now dealing directly with DHL, and are apparently getting priority clearance through customs. It’s not fun, as DP will now have to figure out how to work with DHL’s API. It’s a lot of work and a lot of trouble, but DP still has a few tricks up their sleeve – they’re working on an online schematic entry and PCB layout site and the extremely interesting DirtyCables – custom cables shipped to your door.
