A few of us here are RLab have had an impulse control failure and after seeing the epic post on hackaday about Dangerous Prototypes Hacker Camp we’re off!!
We’re calling it “Continuing Professional Development”.
So in Shenzhen we have a full itinerary of socialising and tasting various cuisine China has to offer as well as following a course based around our own design of a PCB. We’ll get a brief intro into the language, how to barter at the markets and how to find components before we set off on a guided market tour to find the parts for our PCB project.
We’ll also cover off methods of shipping, bank accounts and other commercials.
Next up we’ll spend a few days learning how to solder our projects up at a cell phone repair center.
Top that off with a trip to the Maker Faire and a flying visit to Hong Kong and I think we’ll all be broke and be heavily invested in a shipping container full of lots of electric goodies!
Look forward to the slow boat from China!

In the last quarter of 2013 I helped a group of youngsters at a school in Bracknell build their own 3D printer using a Thames Valley Rep Rap Prusa kit, South Hill Park, a local arts and media centre, made a video documentary of the 13 week project …
The Thames Valley RepRap User Group meets at RLab on alternative Mondays.
We had another session with the X-ray machine last night and got some good images inside larger objects using a Raspberry Pi camera.
We also did some safety tests, and found no X Ray leakage outside the exposure chamber. The region where the Pi was located is looking through a lead glass plate equivalent to 8mm of lead, so no problem there either.
We are inspired by this video
We are getting similar results for large objects, but like Mike we need to go inside the exposure chamber to get the high resolution pictures of PCB and BGA we want.
Next we are going to try to get an x-ray film cassette for the phosphor material unless anyone has one? We can then use a Pi camera on a long ribbon to get through door
Simon Green has put together some amazing interactive shots of our facilities (although they are still a work in process!). Simon backed the Galileo Kickstarter and was after quite a while delivered one of these amazing devices that took the views you can see embedded below.
Here we have our community room, this is where we hang out on Wednesdays and work on projects from software and hardware development. As you can see there is a whole host of electronic scopes, soldering stations, wires, cables, components and desktop PC’s.
In our machine room members have access to laser cutters, CNC machine, vinyl cutter and multiple 3D printers.
Our downstairs workshop with tons of room has equipment for woodwork and metal work with chop saws, a Harrison Lathe, pillar drills, band saws, bench grinders… you name it and it’s probably here – if it’s not post on our mailing list and a member can usually find you it!
We have had a good few spendy problems with our laser cutter over the past few months and it’s one of our most heavily used tools. We need to build up a bit of a kitty to make sure we can replace laser tubes (like this) and power supplies (like we had to recently) as well as mirrors and other consumables.
Step up Andrew Jacobs who built a PIC based monitoring solution, it monitors a pull up on the laser cutter PCB which pulls 8ve when the laser is firing. Andrews design monitors this and keeps a log in the eprom whilst displaying the session usage and overall usage so that members know how much to put in the pot after using the machine.
Simon Green designed and made the case which looks particularly good
The next stage will be to tie the system up to our member RFID cards so we can manage the tabs!
This project by Jon Totham is super cool, using cheap foam insulation boards from Wicks, static grass and acrylic paint with a tad of airbrushing the results are amazing not just for Warhammer but could be really cool on model railways too.
The laser cut buildings are also pretty awesome.
Jon is going to play a bit more with lasers and foam and nitrogen to see if he can get some cooler effects so lets watch this space!
Simon Green has written up a great article about how to create Bump Maps for laser engraving on his blog which you can find here.
Scott recently made a really beautiful lantern for use with a LED flicker lamp. The plywood is laser cut with 4 different designs it clips together and the gaps are cleverly filled with greaseproof paper.
Barnaby turned down some brass hex bar on our new lathe creating a threaded nozzle from scratch with a ø2mm hole 11.5mm deep. The results were amazing you can read all about how Barnaby produced the nozzle on our wiki here http://rlab.org.uk/wiki/RepRap_Nozzle.
