|Mini-Mendel X Axis mini-carriage|

From the beginning, tuesday it's meeting day at AltLab and I've discussed with Mauricio the possibility of using the Mini-Mendel with an adapter, a Pen Holder to write the pcb's layouts. The X axis carriage from the Mini-Mendel was disassembled and after I've finished assemble it, it looked a little wobbly, and we don't want a wobbly printer!
So, Thingiverse to the rescue, and we found the Mendel Mini-Carriage, and of we go... to the Makerbot!!!
This was my first interaction with a 3d Printer, and everything went well... until... when the print reached about 1cm of height, the extruder decided stop the extrusion... damn!
We started over, but there was a suspicion over the laptop, so we've tried using the SD Card to print... it didn't work! Now the suspect is the version 3 firmware... and the laptop... it's a cabala or lack of luck :p
Did we give up? No, of course not, we've selected a smaller piece of the Mini-Carriage and pressed "BUILD", and all went as expected, the first piece of the Mini-carriage was a success!
Let's try another... and all went well.. until the 1cm of height... the extruder failed again :p
It was getting late, so we've closed the shop for the day... err... night.
But not everything was lost, we've plotted a plan to develop a Gen8 electronics, just wait for it :)

Piccolo is a pocket-sized stand-alone CNC platform. For less than $70, you can assemble your personal Arduino-compatible kit for tinkering, developing and deploying basic 3D output. Be it plotting quick graffiti, printing a one-off business card on the fly, or multiple Piccolos working together to create a large mural, this kit provides a platform for experimenting with 2D or 3D digital fabrication at a small scale. This open-source design emphasizes simplicity, and is entirely composed of digitally manufactured components and inexpensive off-the-shelf hardware.

This is Tantillus, a portable self replicable mini printer.
Brad (aka Sublime) went on vacations and brought along his Prusa, there's no need to say... it's big, clunky and not so portable.
He decided to create a mini Ultimaker and this is his prototype.
The building area is very similar to the original Makerbot in a quite smaller package (225mm x 225mm x 300mm), simply amazing :)

Since he was here, he was invited by AltLab to give a small workshop on "PCB Making... The Fernando Afonso way". :)
The method used was Toner Transfer, where you print the circuit layout with a laser printer on cheap magazine paper (the more glossier is better), then, with the toner side over the copper side and woot... the "sandwich" off it go into a slightly modified laminator (around 10 times) and the it's submerged in freezing cold water.
The low quality magazine paper it's easily scrubbed off the pcb and it's ready to the acid bath.
We used Acid Cupric Chloride as etchant, when the pcb is submerged it turns into a... kryptonite green... spooky I say!
In the end we've got a Generation 7 Electronics pcb for the Prusa Air... next step, buy the components and soldering it :D

But something caught my attention, Mónica Mendes using DIY microscopes! She hacked some poor webcams, well, some say lucky webcams (me included), and she was taking a peek into leafs, and I say, nature always amazes me.
Suddenly, at midnight the lights went out... a little piezoesc song starts to play... wait... that's "happy birthday to you" song.... and there it is, a delicious chocolate cake, garnished with some led throwies (what you expected?!?) appeared, Maurício's birthday!!! He got a surprise ehehe!!!

No, this post it's not about the Blender from Blendtec. If I'm going to build a 3D printer, I will need to learn how to make complex objects in 3D on my computer, right?
So, before taking a peek in RepRap.org for recommended software, I took a look at Blender... no, not Bender Bending Rodriguez from Futurama, it's Blender, an Open Source creation suite, offering a broad range of essential tools for the creation of 3D content, including modeling, uv-mapping, texturing, rigging, skinning, animation, particle and other simulation, scripting, rendering, compositing, post-production, and game creation... It's not per se a CAD tool, but it can be used for it :)
And guess what arrived at my mailbox early in the morning... A 7 hour workshop "Blender Beginners Class" by AltLab!!!! I've enrolled already, I can't wait for it :)

This is the printer I'll be building this semester, so, now I'm looking thru my social network, ways of cutting the acrylic.
Meanwhile, I may have found even more partners in crime... building wise and as members of AltLab... who knows?

Maurício Martins (the coordinator of AltLab ) introduced me to Tiago Rorke, a guru on ReplicatorG, Skeinforge, GCode and Makerbot operator.
For 3 hours, I watched and learned how important is the calibration of the printer, the ability to control all variables involved in 3D printing.
Can't wait to get back :D
