After more than half a decade of inactivity, I’ve moved this blog over to Hugo. Does this post mean that there’ll be life in this blog again? Who knows… I’ll at the very least document what I’ve done and learnt during the migration to Hugo. Expect posts on basic Hugo setup, automated builds and and overly engineered release (hey, this was an excuse for me to rub on a little DevOps… I blame #gdbc).
My Oculus Rift dev kit arrived last week and I’ve been playing with it as much as I can… when I’m not consumed by the urge to purge the contents of my stomach (due to playing with said rift) that is.
One thing that I noticed since day one was that the left adjustment knob on my unit was extremely loose. So loose infact that if you were to bump the screen on the left ever so slightly, it’d move out of alignment with the right side.
I haven’t been on IRC for over a decade. But lately, I’ve decided that I should spend more time in my local hackerspace’s IRC channel. Previously I used mIRC, but since my computer isn’t on all day, and I’d like the ability to be connected from multiple devices at the same time under the same nick, I decided that I maybe should use a bouncer. Enter Quassel. It seems to do what I want (for now) and here’s how I got the core up and running on my NAS (639).
Feeling a little nostalgic today, I dug up an picture of a project that I undertook during my undergrad years.
If I recall correctly, this was made while I was in an Experimental Multimedia unit in 2000 and we were learning how to hook up physical sensors to a computer (using an EZIO board and Macromedia Director). However this wasn’t my final project, it was something that I used to explore and experiment.
No, not that kind of e-famous.
I’ve been working on a little project lately. It’s nowhere near complete but after performing the first mechanical test, I figured that I put it up on Thingiverse anyway as a WIP.
The project in a nutshell is to produce an animatronic tentacle that responds to one’s mental state.
The parts were printed with PLA on my Ultimaker. I’m not sure how I should tackle the ball joint as it’s brittle when printed with PLA, and I think the print was too solid (and hence too heavy).
The Ultimaker has arrived!
Can’t wait till I have some time to start work on it. But in the mean time, maybe I should stain the wood a nice mahogany.
A few weeks ago, I replaced Ubuntu on my laptop with Linux Mint Debian Edition (LMDE).
During this time, I haven’t been doing much printing, just waiting for the geared stepper and other parts. This also meant that up to now, I haven’t attempted to connect to the Cupcake via LMDE.
When I attempted to connect to the printer, ReplicatorG 24 could not find the USB-serial port, but the FTDI drivers were installed, and it was listed as /dev/ttyUSB0.
Just yesterday, my geared stepper from MakerGear arrived.
I’ve already upgraded my electronics to Makerbot’s Gen 4 set, so for the firmware and electronics standpoint it was pretty easy.
I made a 6-pin to 10-pin cable to hook up the Gen 3 stepper driver. The MakerBot wiki didn’t give much detail if it was supposed to be the first 6 pins or the last 6 pins of the 10-pin connector that needed to be wired up, but after studying the images, it looked like it was the first 6 pins that had to be wired up.
When someone asks you to name the printers that are able to print themselves, you might have listed the Mendel and/or Darwin. But now, you can add the Makerbot Cupcake to that list!
This isn’t some mini, pint-sized version either. The entire chassis along with the X & Y stages are printable. However, the laser cut acrylic parts are not printable yet.
Along with other printable items/replacements such as Zaggo’s Printruder II and holders (aka dino replacements), insulator retainer, and Z-Stage, you might have an almost fully printable printer (sans rods, extruder heater, build platform, electronics).
A week or so ago, I decided to switch over to Skeinforge 007. Mostly because the Raftless script only works with that version.
Skeinforge being Skeinforge, it didn’t carry over all its settings and I had to manually transfer them by hand. Having said that, thanks to the built-in profiles, there was one that for the Cupcake. It seemed to work well enough, but had a few issues such as the “extrusion over” ratios not working at all for me.
I’ve always wanted a laser cutter. If I could get one, I’d do so in a heartbeat… but I do not have a few grand of pocket change to splurge for one, nor do I see myself being in such a position any time soon.
But just today I heard about the Lasersaur. It still hasn’t really gotten off the ground yet and they are seeking funding to start this project.
After tons of wrangling, I’m slowly getting closer to my goal of producing prints of an acceptable quality (and doing so consistently). I had printed Zaggo’s whistle, but due to extruder issues (as explained below), it was missing a few layers, causing the finished product to be fragile, but if you pressed the layers together hard enough, you can use it.
First there was the firmware issue. Going up to the 2.
