I really like WordPress and was kinda hoping I’d make it to SF WordCamp this year. Unfortunately, it is not to be. If you’re going, I’ve got a silly frivolous request –
If you spot one of those WordPress “W” stickers, would you snag one for me?
I’m getting a new laptop (actually, I’m getting an old relatively unused laptop from someone else) and I’d like to slap an official WordPress, MakerBot, PHP, and MySQL sticker on it.
I can’t help liking the NBC show Chuck. A show about a nerd getting the girl? Sign me up.
After the last episode NBC put up a “playlist” from the show. The music from the show has been really good and I rather like several of the songs from the playlist. In any case, here it is (mostly for my own future reference):
- “Heart Skipped a Beat” The XX
- “Swim” Surfer Blood
- “Rhinestone Eyes” The Gorillaz
- “Polyesterday” Gus Gus
- “Step It Up” Stereo MC’s
- “Tape Song” The Kills
- “Light & Day / Reach for the Sun” The Polyphonic Spree
- “California Desert Party” Jonathan Richman & The Modern Lovers
- “Feeling Good” Nina Simone
- “Friday On My Mind” The Easybeats
- “Ain’t No Sunshine When She’s Gone” Bill Withers
- “Lump” The Presidents of the United States of America
- “October” Broken Bells
- “Drunk Girls” LCD Soundsystem
- “Should Have Taken Acid With You” Neon Indian
- “My Chick Bad” Ludacris & Nicki Minaj
- “The Girl and The Robot” Royksopp
- “In The Sun” She and Him
- “Get Free” The Vines
- “I’m Your Man” Leonard Cohen
- “Holiday” Vampire Weekend
- “Love in Vain” The Big Pink
With Charles Pax’s recent proof-of-concept of a motorized conveyor belt print platform, we’re going to need some software/firmware changes to make full use of these improvements:
- Queuing print tasks
- Removal/auto-wiping of the test extrusion
- Moving the print platform to the front/back/side of the MakerBot for ejecting the finished print
- Ejecting the printed part
- Returning the platform to 0,0,0 / center
From the video posted on Charles’ site, it looks like he’s managed #3 and #4 already. The extrusion path around the print that we see in Nophead’s prints probably would work at #2. I also seem to recall some (such as Zaggo?) have mounted a toothbrush head on the build platform for auto-wiping of the extruder head.
Returning the platform to 0,0,0 is an interesting proposition. This would seem to work best once the opto-endstops are installed. I’ve got my set of six fully assembled opto-endstops sitting in a box next to my MakerBot because I haven’t really needed them and they tend to get in the way of printing. Although the opto-endstops have been removed from the standard MakerBot kits, I think we may now start to see them returning.
Charles Pax has developed a working MakerBot motorized conveyor belt print bed. (Is it heated?) There’s a lot of reasons why this is a big deal:
- This is the fourth MakerBot “milestone.” We’ve reached milestone #1. Milestone #2 (different threaded rods and internal electronics) and #3 (Gen 4 electronics) are noble, but not really transformative goals.
- Continuously cranking out parts is a way to turn a simple MakerBot into a portable factory – rather than a modest means of prototyping.
- Unattended printing is one of the criteria for the RepRap / Kartik M. Gada Humanitarian Innovation Prize.
That title is a little misleading.
I suppose it would be more accurate to say I bought a copy of it. :)
I just started reading Makers by Cory Doctorow and I’m really impressed. He’s managed to capture the giddiness of the dot-com era in a very plausible-near-future sort of way. I’m reading the HTML version on my ‘Droid right now, but reading the first few chapters has convinced me to go old skool and pick up a meatspace copy.
Hey Doctorow! Your evil plan of reverse psychology has worked! By handing me a free digital copy I’m convinced to buy an analog copy of your work!
As a sidenote, by making his work open source there’s all sorts of amazing things sprouting out of it – the entire novel printed on a cash register roll? And other wild stuff you and I never thought of…
I like the mini-Mendel, don’t get me wrong, but there isn’t nearly the kind of documentation for it as you would find for the full fledged Mendel. Sure, it’s a little cheaper, but a Mendel gives you nearly four times the build area. Since the price barrier to entry into the RepRap project just isn’t that high, the bigger issues are probably going to be quality of documentation, support, skill level required, and interest. Is there a detailed mini-Mendel construction guide somewhere?
Just as an FYI for anyone who’s having trouble upgrading your MakerBot Cupcake CNC plastruder firmware, the instructions built into ReplicatorG don’t tell you to unplug the TTL cable from the motherboard and plug it into the extruder board.
So, save yourself 5 minutes of frustration and googling for the answer… and just plug the TTL cable into the extruder board. :)
Yeah, well, that’s what happened to me.
Thanks to Steven, this problem was fixed in all of 30 seconds as I reformatted the SD card as a FAT 16!
I don’t have killer 3D modeling skills – but am able to build a reasonable model using Sketchup. It may be closed-source, but it’s got a fantastic UI. (Heck, Apple has made an entire business model out of this proposition).
I’m trying to design a printable nut and bolt – and have a pretty good design. The diameter of the threads on the bolt is almost 1cm, so it’s pretty large. Constructing spirals manually is a real pain, so I used a plugin/script for generating the internal and external helixes. (Helixi?)
The difficulty with Sketchup is that it’s not really a 3D modeling program – it’s a sketching program that makes really good looking images and reasonably good 3D models. The problem is that it doesn’t really check to make sure triangles are properly oriented, sides are facing the way they should be, or that it is manifold. Oh, and when the model is small it will start making little holes in your object.
There are plugins for exporting Sketchup files to STL files, but either due to a flaw in Sketchup or the plugins, they results are not as good as what you would find in other programs. The end result is that to get a really good STL out of Sketchup I have to design in Sketchup, export as a 3DS model, import into Blender or NetFabb, fix it up, and then export back to a fixed STL.
If you’ve got a better way for transmuting a Sketchup file into a reliable STL, please let me know!
