Visiting my local maker space, and playing with 3d printers

So, Last night I payed my second visit to my local maker space here in Canberra, Make Hack Void. A couple of weeks ago, I came to chat about 3d printers, and this week I came in hopes to get hands on experience with the one they have at the space – a Lulzbot TAZ 5. I’d never had the opportunity to play with a 3d printer before, but had read about them in passing previously.

A few weeks back, my father was talking to me about 3d printers, and that his local Mens Shed was interested in possibly purchasing one to learn and experiment with. With this in mind, I began researching printers a bit more seriously, and I finally made the plunge to go visit Make Hack Void, as it seems like a great place to learn about such things without breaking the bank and buying a 3d printer myself.

Getting involved in MakeHackVoid has been on my todo list for waaay to long, so it’s nice to finally get a chance to visit.

All they guys I’ve met so far have been really friendly, and even though I’ve only been there twice, and I’m generally an awkward, shy person in unfamiliar places, I felt comfortable, included and at ease. I actually felt part of the place.

Anyway, back to the 3d printers. I bought with me a few models that I’d like to print, but starting with a fairly basic model that would print fairly quickly, and allow me to get things done.

The model I was printing was a modified version of this model:

I modified the original print to remove the actual Lyre style shockmount for this print. It’s pretty basic, but it prints fairly quickly (this took about an hour), and lets me check the sizing of the clip, and cold shoe, as well as seeing if the arms are likely to snap in half as soon as I try and clip in the microphone. The model I printed is shown below, and I’ve uploaded it to Thingiverse at:


The Lulsbot Taz5 printed my first print fantastically. It was touch and go early on, when the long skinny clip arms came off the print bed, but damage was minimal, and the print kept going, all the way to completion, and I ended up with a very usable print.

3D printers are mesmerising to watch, and the Taz5 sounds like a happy little robot buzzing around the printbed as it worked away.

As I mentioned earlier, the print I did last night took about an hour to print. While it printed, we chatted about 3D printers, and some electronics, and I managed to snap a few pictures of the print in progress, as well as the settings we used:

Finally, once the print was complete I let the printer cool for a few minutes and then the print popped right off the print bed.

Once I got home, I  snapped a few pictures of the completed clip, so you can see the details of the print, and attached the mic to the camera, so you can see it in action.

So my first hands on 3D printer experience went better than I could have expected, and everyone at Make Hack Void are really friendly & inviting. I look forward to coming back again soon so I can have good chat with everyone, and play some more with the printer!


Quick and simple laptop mod – a tape measure

Here is a very quick post to show an idea that I had recently.

Its so small, that It’s hardly worthy of a post, but I thought someone might find it interesting.

Often, I’ll find it handy to know how big something is while surfing the net, or trying to size up something I’m looking at, and I’ll either need to go find a ruler, or make a rough guestimation of the size.

Then I had a brainwave, what if I stuck a ruler to my laptop?

printable rulers can be found at various places on-line, and I found a neat short ruler at, which is the one pictured below:

I printed it out, measured it for accuracy, and adjusted the size a few times and printed again until the accuracy was close enough for my liking before cutting it out and sticking it down with double sided tape.


The little ruler was a neat size, but I thought a longer ruler might be helpful, so I was going to find a larger ruler to print out, then I thought of an easier idea:

Ikea give away paper rulers at their stores, and I’ve had a bunch kicking around for ages. I thought I could save myself some trouble, and use one of those.

Instead of printing off another ruler, this time, I chose to go the lazy route, and cut up an Ikea measuring tape.

I split it down the middle, so i could use both the inches, and the centimetre  measurements, and stuck them down to the laptop with double sided sticky tape like before.

As you can see from the pictures, the results aren’t exactly super neat and fancy, but they do exactly what I want them to do.

Hopefully someone can find this simple idea useful.

Quick Picaxe Prototyping Part 4 – Variable Resistor

The Variable resistor. by far the easiest "circuit" to create

The Variable resistor. by far the easiest

so this installment is by far the easiest of these circuits, only consisting of 2 components, the Potentiometer, and the circuit block. I chose to use a 10k pot, as i have a bunch of them in one of my parts boxes. I’m not sure if it matters what resistance they are, i’m guessing its not overly critical, as i couldn’t see anything in the picaxe manual about values to use.

If you haven’t worked it out already, the terminal block is soldered straight onto the potentiometer. I had to bend the pins of the pot down, so i could get the terminal block nice and close.

So, go have fun kiddies.
