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.

AD584 vs. LM399 Voltage Reference Test Setup

One of the upcoming future projects is going to be the build of a high capacity 48V lithium battery bank. In order to be prepared and able to measure cell voltages with single digit mV precision, it became clear that the lab's multimeters may not offer high enough resolution or accuracy. So we are trapped in the chicken - egg situation where we don't have good enough equipment to verify our measuring devices.

Precision Voltage References to the rescue then.

But how stable and accurate are they? In order to help us and share what is learned with all of you, a cheap AD584 and a not so cheap LM399 “precision voltage reference” were purchased.

As you can see, so far (over the last 5 hours) the LM399 really wasnt worth the money…

New Blackmagic Micro Cinema Camera DOA

This should have been the new cam for the lab bench to make it easier and more streamlined to record whats happening. Sadly, it arrived DOA, so the only new footage it could offer was how the dead sensor looks like.

Kudos to, who not only made the RMA process easy, but also covered the shipping costs:

As soon as the replacement arrives, there will be an unboxing and more test footage of it,
so dont forget to Follow!

Building a new Render Beast

Doing videos for LBRY is taking a toll on the current hardware. In order to streamline publishing of more actual videos, Blender rendering, other CPU/GPU intensive visualizations as well as training advanced Neural-Networks, a new and far more beefy Machine is needed.

While at it, we might just build it like a tank as well, completely from the ground up, with custom frames/cases, optimized for highest efficiency, environmental compatibility and lifetime endurance. This picture shows only the cooling part, with the pump/reservoir in the middle, left and right to it two radiators will take care of business.

LimeSDR USB-A Unboxing

Finally the most competent SDR in our LAB arrived: The LimeSDR. Although the rtl-sdr and the sdrplay are great for playing/receiving and the HackRF/rad10 have been great advances, the LimeSDR is a completely different animal. Here's the unboxing of it.

Basic rigging and setup will follow soon.
