Apollo-NG Mobile Hackbase

Apollo-NG Hackerspacecraft

Apollo-NG is a mobile, self-sustainable, independent and highly-experimental Hackbase, focused on research, development and usage of next-generation open technology while visiting places without a resident, local Hackerspace and offering other Hackers the opportunity to work together on exciting projects and to share fun, food, tools & resources, knowledge, experience and inspiration.

UmTRX publicly released

The UmTRX is a dual-channel, wide-band SDR transceiver (so it can send & receive) with 1GbE connection. It is developed by Fairwaves team to be used as a transceiver for OpenBTS GSM base stations, but due to its software defined nature, it could be used for many other radio applications as well.

[UmTRX SDR]

If the speed of development continues at this pace and more and more people finally realize the benefits of open resources and release their projects under an open & free licence, in less than 10 years, there won't be any proprietary, patented and overly expensive, hardware-based radio left on the planet. Awesome!

HOWTO disassemble a brushless outrunner motor

Shortly after the collet-chucks-for-picocnc-arrived, the brushless outrunner motors for this project followed suit. After closer inspection, both motors appear to be as equal as their datasheets suggested so the first prototype will be assembled with the brandless 50EUR C5045 890KV brushless outrunner (the red/black one on the right).

In order to progress picocnc we have to replace the original shaft with the new collet. But how do you take it apart without special tools? The following 7-step HOWTO will guide you through the simple dis-assembly process:

Motor-Porn: Honda GX25 moved into new APU rig

What started out as a simple thread on a mobile-home board, ended up in more than 50 pages of discussion about a neat and small generator project based on a Honda GX25 and a Torcman 430-30 brushless outrunner motor. Some people always seem to ask, why anyone would build something like that, if they could get more output power for less money from a ready made product? Because available products don't really match the requirements and why would anyone pay money for something one actually doesn't really want or need?

Apollo-NG needs multiple independent energy sources to be able to function autonomously and independently from grid infrastructure. Although the basic requirements are supposed to be covered by alternative power technologies like solar and wind power, it never hurts to have a fallback for a rainy day. That's where the apu comes into play:
