Possible future printer upgrades methinks :)
The PolyStroooder Tri Hotend is three separate hotends all rolled into one! This three nozzled all-metal bowden hotend is capable of printing materials that melt under 300 degrees Celsius, including nylon and polycarbonate. Explore new technologies that are only available with the Tri Hotend, like a Titanium alloy thermal isolator, as well as Tungsten Disulphide, which is used in certain areas of the hotend to prevent blockage.

Looks like something from the millennium falcon.

Five pack of Arduino Uno just arrived, one step closer to having next month's Hackspace introductory course ready.

Yes, they say "made in italy" on the back, but they definitely came from china.

Every time I 3D Print a pointer, I get the strangest error... :)

Still I suppose the old "Printer on fire ?" message is now technically believable

Cheapy level converter works great, LV reference pin is actually an output (150mA max) it seems. Tested with the cheap RFID card reader I received the other day, works fine.   Hint of the day: if your going to be lazy and use rfid tag serial numbers for access control, dont use a passport, the number changes every time you read it :)

This little fella seems to work pretty well, MIFARE rfid tag read/writer, at a bargain price too; it, a tag and a card for only £2.65

Only downside is that its a 3.3v device, and these darned Arduino boards are 5v. a cheap level converter is now on order.

I will be covering how to use the various open source tools to take a 3D model from the web and print it, as well as giving a simple guide to using some of the easier to get started 3D CAD programs
 
A gentle guide to how a 3D printer works and its limitations, where to find objects to print, and how you go about printing them. Also covering a few simple and easy to use ways of creating your own 3D objects.
