Arduinos and Macs

Posted by ian.rees on August 08, 2015 in Projects tagged with , ,

This evening, I finally got around to unwrapping the Arduino clone that came with my DSpace membership. Starting a project for the board couldn't be easier, using the nice Arduino IDE from https://www.arduino.cc, but I ran into a little snag when it was time to upload the program onto the board. It turns out that these clone Arduinos use a newish low-cost USB to serial converter chip called a CH340G, rather than the FTDI brand chips used in the genuine Arduino boards. The CH340G that isn't supported by MacOS by default, and I use MacOS, so the board didn't show up in the Arduino applicatio

As you may have heard, the Dunedin Maker Space is getting ready to move to a new location in the Northeast Valley. The Allen St Workshop provides exciting new opportunities for the maker space including a concrete floor, collaboration with other like-minded folks, and there's a fibre optic box out front! We'll continue to meet in the current King Edward College location as usual until 8 August when the move to the Allen St Workshop will commence. Stay tuned!

Sourcing RepRap parts around Dunedin

Posted by Luke Easterbrook on October 31, 2013 in Projects tagged with

Things to note Don't get too hung up on bolt length. Get something longer than required and cut it down with a dremal or hacksaw. Some reprap parts lists don't include the extruder parts, so make sure you read what you need for those as well. Please add comments for other places you have bought stuff or for things I need to fix. Fasteners: (Nuts and bolts etc.) Get them from a fastener shop Hylton Parker fasteners EDL Fasteners You can also get stuff from Mitre 10 or Bunnings but it costs a bit more for some things and not everything is available. 8mm Threaded rod Can ge

Electronics 101

Posted by Paul Campbell on June 01, 2013 in Talks tagged with

I've included here the electronics1 talk I gave this week as a PDF Remember the simple takeaways from this talk: - the relationship between voltage, current and resistance - in particular bigger resistors mean less current - capacitors pass AC and block DC - inductors block AC and pass DC - bipolar tranistors control a large amount of current with a small amount of current - FET transistors control a large amount of current with a voltage Please go and play with the excellent circuit simulator at: http://www.falstad.com/circuit/e-index.html try playing with resisto

Using solder stencils

Posted by Paul Campbell on April 23, 2013 in Meeting Notes tagged with

I talked last week (April 18th) and gave a demo of using solder stencils to  make surface mount PCBs  and promised to post useful links. I had my stencil made by Smart Prototyping ( http://smart-prototyping.com) - they offer stencils starting at $20 when boards are made (http://smart-prototyping.com/index.php?route=product/product&product_id=142) Seeed (http://www.seeedstudio.com) also offer stencils for $70 (http://www.seeedstudio.com/depot/pcb-stencil-service-p-1391.html?cPath=185) I ordered the stencil jig from AliExpress from: http://www.aliexpress.com/wholesaleproduct/w

Fab8NZ Un-Conference and Academic Symposium

Posted by Reece Arnott on September 27, 2012 in Talks tagged with

Here are the Fab8nz conference talk slides that I used for the talk I just gave. Included in these slides are three video clips that can be found on YouTube: - The KamerMaker Grand Opening with a first print of their 2x2x3.4m 3D printer is here. - The making of the conductive ink for a ballpoint pen is here. - The Solar Sinter video is here. There are also a number of other resources that are also mentioned: - Vik Ollivers website where he has blogged about some of his techniques for constructing the "fiddly bits" of a Reprap extruder. - The FabLab Store where you can buy the

We spent tonight doing a guided build.  We had two goals: 1) Learn how to take 3D pictures with one camera and the open source GIMP software. 2) Make our own funky anaglyphic glasses using Lee colour filters 026 (bright red) and 354 (special steel blue) and paper, cardboard, cheap sunglasses, or our Reprap printer!   Step-by-step instructions are here -> AnaglyphsPDF .  GIMP software is available here -> www.gimp.org

G'day everyone.  Thank you for your kind attention during Thursday's (9 August 2012) presention on my initial playtime with Paul's Shapeoko CNC router.  Paul encourages people to use the router (with care) to MAKE! As requested, I have posted the presentation slides here.  Too late to include in the presentation, but cool tools for CNC folks to use include the OpenScam toolpath visualistion tool at http://openscam.com/ and the ubercool half-tone application that MetalFusion made to convert grayscale images into .dxf and Gcode files so that you can engrave photos into materials with a con
