Help with Xvfb, Eagle, and permissions on Ubuntu?
Trying to get Eagle working on a headless Ubuntu box using X virtual frame buffer. It sometimes kind of works, and there’s a general feeling that permissions are involved. xvfb-run -a /opt/eagle-7.3.0/bin/eagle -C’EXPORT IMAGE schematic.png 600; QUIT’ /var/www/dangercore/temp_upload/bp.sch xvfb-run -a /opt/eagle-7.3.0/bin/eagle -C’RUN /var/www/dangercore/eagle/ulp/bom.ulp; QUIT;’ /var/www/dangercore/temp_upload/bp.sch Two commands need to be run. The first is a […]
Bay Area Maker Faire 2015
Please have a free Sierra Nevada for us at Friday night’s Maker party, we’re skipping this one. Too much going on here in Mom’s basement to venture out into the sunlight. If you’re at the faire early you can still check Noisebridge hacker space and recreate the Mission District Taco Crawl.
3D model .STL to .PNG preview
Bing search sucks. Tried a bunch of ways to get image previews from 3d model .STL files. OpenSCAD does a decent and fast preview, but you gotta figure out where to put the camera for a good scene. The Linux repositories with OpenSCAD are outdated so you have to compile from source. Fire it up […]
CNC3020 assembled in 30 minutes
Got it bolted together in less than an hour. Works. Except the safety stop that is, it does not work at all. Next the software.
CNC3020 milling machine arrives
Hacker Camp Shenzhen volume 4 was a huge success! It seemed like half the hackers were playing with CNC mills of some sort. On the second day of camp I spent an awesome afternoon brainstorming CNC PCB making with Drew and hunting Depu market for copper clad, rivets and other parts. We also had the […]
Free PCBs massive fail, now shipping
Late last year I spun off the Dirty____ source code into a free PCB fulfillment system (Filthy Hole). The system is modeled after Amazon.com – print packing lists and prepaid shipping/address/customs form on 10x15cm labels. It is way easier for the back office to pick and pack, and follows the same workflow as Dirty PCBs. […]
On the second day of Taobaomas
It is 8:30pm in China. Time to review today’s Taobaomas haul. Taobao recently started taking foreign debit and credit cards, so for the first time I feel fully Taobao-enabled. Today we have another load of food imports. Hope thus isn’t annoying you too much, I just want to show the variety, price, and speed that […]
On the first day of Taobao Christmas
Taobao, the Chinese shopping site that combines eBay, Amazon, and Alibaba, recently got a lot easier for foreigners to use. As Sjaak documented in his Taobao buying adventures a few years ago, most foreigners use an agency that takes payment via Paypal, purchases your babies, and forwards them to you via DHL or airmail. Even […]
PCB Christmas Tree Ornaments
Our office Christmas Tree is decorated with PCBs this year. Bitmap images of classic Christmas iconography were imported into Eagle for the board outlines. Decoration was supposed to be exposed silver areas but something went wrong. Instead, we just traced over the masked copper with markers. Should you like your own next year these will […]

DIRTY TUESDAY: Adventures in SQL with stats and stuff
A few months ago we started a private PCB website so our team can get cheap PCBs from a fab in China. Someone spilled the beans, and it hit Hack a Day, Hacker News, etc. We almost shut it down, but it was too much fun to hack and refine the process. Dirty Tuesday is […]

DANGERCORE: PHP and Javascript developers needed
Good at PHP and/or Javascript and looking for part time projects? We need to hire a couple PHP and Javascript programmers to work with me on several large projects long term. Some of what we do will be open source immediately, some will need to be secured against hacks a bit first, some will be […]
Hacker Camp Shenzhen metro cards
The next hackercamp Shenzhen group gets a customized Shenzhen metro card. Its always a pain to get everyone in the group a card, get it charged, or buy tokens. This time we’re just going to hand them out. These customized cards were the same price as a normal metro card.
