So lets talk about 3D printers and their fumes. I’ve been heavily into 3D printing for about 2 and a half years, first building a Prusa i3 clone and later buying an Ultimaker 3. One of the things that has always bothered me was the possibility of toxic fumes. About 2 years ago, a study came to light that, yes, indeed, 3D printers do emit things that aren’t good for you. There was a lot of discussion about it around that time, but it seems to have died down.
So you’ve got this awesome Ultimaker 3 printer with a build-in webcam. But no way to record and review your prints later on. Are you going to sit around, babysitting your printer at night?
One of the great things about 3D printing is that you can print an entire model in one go. The typical example is the fully assembled “print-in-place” ball bearing as shown in the image above. This is printed in one go, no assembly required. However, the tolerances are pretty small which requires a well-tuned 3D printer. In this article, I describe how I tune my machine for perfect fit.
It’s that time of the year again. Time to look back and look forward.
Make: Paper Inventions is a book about things you can do with paper. This is a very practical book with projects going from actually making paper, to paper machines and even a bit of origami. It took me over 10 months to get through this book. Read on to find out why.
There are many tips out there to improve your blog. There are just as many people out there who claim to have found the one true way to maintain a blog. Over the last 10+ years I’ve run a blog in some form or other, I’ve read it all. So why would I read yet another book that claims to offer the magic formula for technical blogging?
Today, I’m soldering. I’m putting together a basic electronic circuit, just because I can. Thanks to the Boldport club, this is going to be a monthly thing and, on top of that, I get an insight in the history of the circuitry that I’m making.
Jekyll is a static site generator. It allows you to run a blog on a minimal server with minimal security worries and no spamming. Because it’s all based on files, it tends to be a bit more technical than blogging in WordPress. I’ve previously written about Jekyll, but now it was time to actually migrate a site from WordPress to Jekyll.
Over the Christmas break I built a RepRap 3D printer. Everything went well until it was finished. The information on getting started with actual printing is very fragmented and all over the place. So here’s a short guide for any budding RepRappers who can’t wait to get started.
Last year, I followed the Functional Programming course on Coursera by Martin Odersky. It was a thorough introduction to Scala. Right now I’m reading Pragmatic Scala by Venkat Subramaniam. So it was about time for some actual Scala code.
