Re: FreeCAD on PI4 and Raspbian Buster.

Yep I came here to find the link for compiling, then I thought I would try an install. I noticed Blender was pre-installed, maybe??? OpenSCAD, Wings3D, Inkscape... yep all working. That's great! Blender? Wow - I never got to learn how to use it - but did use to occasionally to convert 3d objects fr...

Re: FreeCAD on PI4 and Raspbian Buster.

Pi4 8GB + SSD (and USB3 case) ordered - all in preparation (and anticipation) of switching to 64bit Raspbian! :D

Thanks for letting us know. I was just thinking of needing to recompile it again as I did it for regular (32bit) Raspbian.

Android SDK Build Tools (for RPi's arm platform)

Hi all,

Does anyone know if is there any pre-build Android build tools version for armhf (except 6 years old https://github.com/skyleecm/android-build-tools-for-arm)? Or how to make my own?

I've got gradle android app which I would like to be able to build on RPi4 (no 64bit version of OS, sorry)...

Re: Remote Java IDE for Raspberry Zero, where to start?

Down the similar path - you can use this (http://remotevm.abstracthorizon.org/source.html - I promise to 'modernise' it these days) - you can push your code from development machine to RPi and execute it 'remotely' (along with reading stdout back in your IDE's console)... Do ask if you need more hel...

Re: good java IDE with Intellisense

RPi3b+ might be a bit tight for developing java on it. RPi4 (with 4GB of memory and fast storage like SSD) is more like it. IntelliJ works perfectly well. Eclipse, unfortunately, switched 32bit support off, so there won't be anything else there... Also, picking up any other desktop/laptop and using ...

Just to be pedantic - .class files are not encrypted so - there's not need to decrypt them. They can be 'disassembled' and hence decompiler link in previous post.

Re: Pi zero W possible to increase wi-fi strength/range?

Quick (lazy) question fired at Google and the answer is:

"As the unit we began with was meters we now know that the wavelength of a 2.4GHz signal is 0.125 meters or 12.5cm."

12.5cm / 4 = 3.125cm or 31.25mm
