Da Vinci 3D Printer Arrives

Yesterday my XYZ Da Vinci 3D Printer arrived. I had a really fun day setting it up and doing some test prints. The first print I made was the “key chain” print that is on the firmware. This created a rather lame “XYZ” logo that I assume you can attach to your keyring.

Next, Helen created a model in XSI of an egg cup that looks like a bird’s nest. She exported it to Blender and then we created an STL file which we then imported into the XYZ Printer software. The print for this took about 3 hours, and the results were less than perfect. The egg cup still looks pretty cool though.


This morning I printed a 3D printed shell and ordered an Arduino so I could reset my filament cartridge as described here.


So far I’m pretty happy with the printer. It was pretty cheap at £500, and I’ve really enjoyed playing around with it. I’m keen learn a lot more about 3D printing, and I think that this printer is a great one to start with.

Configuring a Jaalee iBeacon Transmitter

I received 5 iBeacon transmitter units from ibeaconmodules.us today. They arrived unassembled, so I put them together and configured their local names with my iPhone.

The first hurdle I found in setting them up was getting the battery in the right way around. Each unit comes with a watch battery, and you need to have the side with the plus sign facing away from the circuitry.

Surviving Post-Scarcity

I’ve been reading the “Beyond Scarcity” series on FTAlphaville recently, and it’s made some very interesting points. The posts argue that the current economic environment is deflationary with regard to goods. I think that is true, and one of the reasons is because of technology. Firstly technology is constantly making everything more efficient and because of global competition this is both reducing the production costs and making goods cheaper. Secondly technology is causing structural unemployment, which means less people have money to spend and there is less money flowing around the economy. Other factors causing deflation are the tight monetary conditions, the aging population, and potentially the effects of quantitative easing.

Hacking the EZ430 Chronos Watch on the Mac

Today my TI EZ430 Chronos Watch arrived, and I spent a little bit of time hacking it on my MacBook Air. It turns out that even though the documentation seems to require either a Windows machine or a Linux box, you can communicate with the watch from the Mac by modifying the serial port information in the TCL source. I learnt this from a Google Groups post, and I’ve copied the modified TCL source onto my Github account.

Race Against The Machine

I just finished reading the Kindle book Race Against The Machine, a book I thoroughly recommend. This was the driver of the NPR article I blogged about recently.
The book is mostly oriented towards the US, although the issues they discuss seem to be prevalent across all major economies. The authors make the case that technological improvements are severely impacting every job market except those for highly-skilled individuals.
