I know that it is beyond my capabilities but I love it. This suit not only make you "feel" the objects perimeter by stopping your hands and fingers when you reach it, with some sort of piston I guess, but also let you feel the weight of the objects that you lift, with the same pistons. Or maybe the resistance of a door that you open. How can this thing be 3d printed? What parts sensors and elby Autarkyboy - Let's design something! (I've got an idea ...)
What do you think of this for a RepRap? It's a brainstorm for a control system easily pluggable in any machine with a single fiber optic cable.by Autarkyboy - Controllers
After seeing the solar sinter by Markus Kayser I thought that maybe selective sintering is easier than I previously thought and I want to build a direct metal sinter machine eventually, I had a few brainstorming ideas but I am not sure if they will work at all, so before doing stupid things I am going to ask more knowledgeable people on the forum. You can replace the laser with a fresnel lens poby Autarkyboy - Powder Printing and Selective Laser Sintering
As for the cost, the plastic filament costs 45$ for 5 lbs, natural, coloured a little more That's about 20$ / kg What's the weight of the miniature? 20 grams (a random guess)? that's 40 cents to print plus some energy, a minor cost.by Autarkyboy - General
What about commercial 3d printers like Stratasys? Do they have the resolution to print this? What about a 5 axis mini milling machine? Like this , it cost 1225 $. Has anyone any experience with milling?by Autarkyboy - General
What MAKERBOT did is totally in the spirit of the GPL license, they created a fork of the product. The gpl will let anyone to take your software, to make changes and to redistribute it. Let's suppose that there is a guy that develops a software, you make a change but he disagree with your change and he doesn't want to incorporate it, or let's suppose that he takes a decision on the development oby Autarkyboy - Administration, Announcements, Policy
And besides, it's counter-productive to be open source, to let all the people copy your software, modify it, redistribute it for money and to hide to be open, actually open source scams are the exact opposite, people claiming to be open source where they don't redistribute the source code, or creating new open source licenses incompatible with existing ones, making it difficult with other means tby Autarkyboy - Administration, Announcements, Policy
There are so many companies that claim to be open source when they are not, that are open source but in the closest possible way, that distribute open source software but at the same time they say that open source is inferior to closed source, makerbot is definitively not one of those and accusing them just creates confusion.by Autarkyboy - Administration, Announcements, Policy
The frostruder is under the GPL license, you were misled to think that it is under a creative commons license cause the creative commons made these little icons and summaries about some common software licenses putting CREATIVE COMMONS before their name, misleading people to think that these are creative commons licenses where they are not. This is something that has already been criticised. Thby Autarkyboy - Administration, Announcements, Policy
Maybe to use a lathe on scrap metal was too optimistic, what can you use on lathes as a base? I made some calculations based on the M8 nuts and washers, you need 104 nuts and 104 washers. I found on the metaldepot site that a 9.5mm (3/8 inch) stainless steel rod can be bought for 5.6 euro / meter, I don't know if you can just buy one of those and put it in the lathe. The density of steel is 7.by Autarkyboy - General
Hello, I was looking at a pic of "Mendel Hardware plus Belts" at the reprapstores website and I have god this idea, to me it seems that almost all the hardware parts required for a Mendel can be made on a metal lathe, bolts, nuts, washers, smooth rods and threaded rods. I thought that a RepRap and a metal lathe together can replicate more parts, in a RepLab kind of way. I have no experience whaby Autarkyboy - General
Sorry if I am a little off-topic, I downloaded some stl parts from the repository, like and I noticed that it has 2388 vertices but after an operation of "remove doubles" in blender the vertices go down to 384. I think that there are some wrong vertices too, they are not really duplicate but they are really near and I can't understand why they are there, maybe if you remove them you can have prby Autarkyboy - General Mendel Topics

Hello I posted a similar message some time ago but I think that it was filtered by an anti-spam bot cause it was full of commercial links, so I rewrite it with no links. I want to build a greenhouse so I searched the web about the topic. Greenhouse glazings usually are made of glass, polycarbonate or acrylic, they must let the light pass through but they must retain the heat and they must be liby Autarkyboy - Let's design something!

Hello, is it possible or economic to print isolating panels for greenhouses with a reprap? I ask cause they are usually made of glass, polycarbonate, acrylic or other plastics. They should let the light pass through while at the same time they should thermally isolate the greenhouse and they must have a lifespan years. Usually their performance are measured in R-value, % of the light that can paby Autarkyboy - Let's design something! (I've got an idea ...)
