Just go to slashdot if you want ads, trackers, pictures and video's

I started with making 3d models of objects and weapons for games 15 years ago. Usually based of existing pictures or blueprints. Copy existing stuff is easy, even without measurements because good pictures with good camera can still be used for scaling stuff. I used to have about 100GB picture archive of all sort of stuff to be replicated into 3d models for game us.

Getting to know the tooling before you make something new really is the way to go. I currently use Freecad and Openscad. Freecad really has a way to work, sometimes going at something from a certain direction really helps you curb the complexity and pitfalls you can get yourself into. I can suggest most of the videos made by https://www.youtube.com/user/cad1919/videos on youtube. Usually videos without audio just doing the modeling. Often I am surprised at his route to completion, usually fairly efficient and direct. For the item you want to make I would suggest following his example.

You should draw it out on paper in maybe 2 or 3 perspectives and do all the hard calculation and then just replicate it in 3d.

Freecad is really as user friendly as it gets for actual good small tolerance Free CAD. There are however some usability and or nagging issues. Like how you break your model and can't continue the route you had because the chamfer or join brakes your mesh :).

On a side note are you sure your idea is novel and new, I assume someone has made it before and you can copy ;) a few months ago there was a N mechanical mechanisms link on hackernews, it might be in there :).

Edit: don't look at the videos you find on youtube and just copy the thing their making. Make your own stuff just steal their workflow.

Also do everything using coordinates and measurements not drag and drop. Might help you visualise it better.

It is the formfactor of a portable computer that you could own completely, unlike anything more mobile where at least some of the chips are configured and run by someone else.

Also you would take your I/O with you because it makes no sense if you hardly trust a device you don't let leave your side to interface with some static hardware that any third party could have modified. Current monitors have more processing power than early mainframe computers and more than enough room to hide rf equipment for remote snooping.

Essentially what you really want to build is the University of Twente SDR that's been up for a few years and you can listen in on over the web :)

Iceland? They kicked the banks out and the pro-USA goverment and their three letter ties.

With evolution, if this really was a problem, it would not be one in a few generations :)

Unfortunately the distribution is not optimal for economic reasons. I live in a village (Zoetermeer) (123 000 people) with an density of 9000 people per square mile. Is not uncommon for these densities in the Randstad, where the avarage density over this area is around 4000 per square mile.

I actually have 3 windmills in my back yard (the local industrial estate across the busy through-road)

You never hear them and hardly ever notice them once they are placed.

https://www.google.nl/maps/@52.037446,4.506723,3a,75y,90t/da... < is one of them.

Zoetermeer used to have 3 other windmills about 20 years ago, those were replaced with these.

Only thing i would like is to get cheaper power, that has not happened :|

I have been in the one in The Hague in the old bank building, now owned by massive ISP.

It is a great elevator and you have to do some effort to kill yourself (someone has unfortunately). It had a tray with a cutout switch that when you would get stuck between floor and elevator would stop it and building security had to reset it.

I have done many a lap in the elevator for fun :).
