Replicator 2X has arrived!!!
My Makerbot Replicator 2X has arrived! I won this baby in the Makerbot Thingiverse Customizer Challenge (: www.makerbot.com/blog/2013/03/10/makerbot-customizer-chal... :) and it arrived in less than 2 weeks.

Sadly it got damaged a little during shipping. From the cardboard box it's obvious that the fedex guys must have handled it quite rough :( but thanks to the excellent and super fast Makerbot support I got it repaired in a few hours :)

I immediately tested the two material print by printing the makerbot coin that is on the SD card that comes with the printer. This worked out of the box :)

Because I really like PLA much better than ABS I then decided to switch to PLA. The switch somehow clogged the right nozzle but this was not really a problem since it's super simple to get to the hot end to clean it :) On the other printers I've used so far a clogged nozzle usually means you spend a few hours taking the extruder apart so it was a very positive surprise that it only took me 15 minutes to clean the nozzle this time :)

Then I printed an emmet bearing because gears are awesome: www.thingiverse.com/thing:53451

And then the first "useful" parts: Two customized spool holders (both in the picture): www.thingiverse.com/thing:44906

After taking this picture I printed the replacement parts that I need for my old 3D printer which broke a few days after I had won the Replicator 2X...I guess it was jealous ;)

To summarize the day: I'm really impressed by this machine so far and I have to print more two color designs ;) Stay tuned for a two colored music box...

Next Iteration of Fully Printed Parametric Music Box
Next Iteration of the fully printed music box. I closed the case that holds everything in place and now it's much more stable and also sounds better.

The snapping axis holders are now very tight but the gears will stay in place even if you drop it on the floor...I tested this ;)

Fully Printed Parametric Music Box With Exchangeable Song-Cylinders
This is my entry for the Makerbot/Thingiverse/Customizer Challenge :)

It's a: Fully Printed Parametric Music Box With Exchangeable Song-Cylinders :))

This specific one's has 13 vibrating teeth that are calculated to each half tone covering one octave :) While they might not be perfectly tuned the relative frequencies seem to match :)

I used the formulas from this Wikipedia article (sorry it's in German):
de.wikipedia.org/wiki/Durchschlagende_Zunge#Berechnung_de...
Basically this gives me a function to calculate the length of the tooth given the frequency I want, the height of the tooth (like the thickness of the wire in a piano), and the density and the elastic modulus of the material I use: PLA :)

Fully Printed Parametric Music Box With Exchangeable Song-Cylinders
This is my entry for the Makerbot/Thingiverse/Customizer Challenge :)

It's a: Fully Printed Parametric Music Box With Exchangeable Song-Cylinders :))

This specific one's has 8 vibrating teeth that are calculated to be matched to C,D,E,F,G,A,B,C' (like the white keys of a piano). While they might not be perfectly tuned the relative frequencies seem to match :)

Pb free soldered DC/DC boost converter PCBs
These are the new DC/DC boost converter boards based on the TPS61200 chip from Texas Instruments: www.ti.com/product/tps61200

It can convert any voltage from 0.5-5.5V to any other voltage up to 5.5V and can also be used as a constant current source for LEDs witch you dim by PWM with an optional enable input. So to test all those options I soldered 5 different versions, from left to right:
* 200mA constant current source for high power LED
* 500mA constant current source for even higher power LED
* 4.65V voltage source
* 5V voltage source (TPS61202)
* 3.3V voltage source (TPS61201)

Board size is 19x14mm and they can be used on a breadboard :) They seem to output the correct voltages but I have not tested the current sources yet. If they work as expected you will soon see them at the hackerspaceshop.com ;)

MagicShifter Prototypes
Everything works as expected :)

Yesterday I had a hacking session with clifford and although we wanted to work on the firmware we ended up designing and test-printing snap-fit designs for the case :) Here are some of the snap-fit prototypes along with the current prototype fleet (well some are missing because I did not have enough batteries)

MagicShifter V2.4 FINAL!
I soldered the LEDs and both prototypes work like expected. I have not tested the IR PWM yet though...(have to write more firmware for that) Just waiting for the new case...it's printing right now ;)

MagicShifter V2.4 FINAL!
one of the two new boards we soldered tonight. I plan to assemble the LEDs tomorrow. So far it looks very good :)

First intricate print with new Printer :)
"Snowflake, a hexagon chain mail"
Created by: Ablapo
www.thingiverse.com/thing:32437

Parts that, when sliced, have many small islands are hard to print without a raft because eventually one of those islands will seperate from the building plate and your print will soon look like a game of life spaceship with a one cell error ;) So this is what I had to try out ;) It still does not stick perfectly because the base plate is not 100% straight but these things are just calibration details ;) I'm so happy about my new Solidoodle because although I dont have all the building plans it runs on a complet open source toolchain (well I'm using KISS Slicer but I COULD replace it with a real open source one if I bothered). Next (when I get more money ;) I want to try the new Makerbot 2X ;) I had some troubles setting my Solidoodle up so maybe the instantly works magic is better at Makerbot. It should be because it costs way more... I really need two colors (black and transparent) for my MagicShifter case ;)

DIY MIDI Organ
A video of it can be seen here: www.youtube.com/watch?v=qeIU2NyJtTs

First organ module 16 tones, another 16 tones will follow.

Solenoids: hand wound, 2200 turns, ~0.5A at 12V, a nail with permanent magnets on the top and bottom, rubber valve cut from a broken bike tire, the green LEDs are fueled by the inductive kickback :)

Pipes: PVC tubes 20mm diameter, lowest note: B (plugged)

Wind chest: plastic food storage box

Wind supply: still an issue, at the moment a 12V air pump

Electronics: MIDI signal to Arduino to Shift Registers to MOSFETs to solenoids
Arduino source code: bitbucket.org/wizard23/arduinomidiconroller/

Built at Metalab, Vienna metalab.at
