Chinese Chipmaker Loongson Enters GPU Biz with New iGPUs
What grabbed our attention was the phrase that the LS2K2000 features the LG120 GPU 'core independently developed by Loongson, further optimizing the graphics algorithm and performance.'
Given the applications that the LS2K2000 is aimed at, it is unlikely that we are dealing with something very advanced in terms of performance. In fact, we believe it would be pretty much underwhelming when it comes to power consumption. Yet, a basic GPU from a CPU-centric company looks curious, and these types of foundations can be built upon.

Control your mouse by playing the trombone | HackSpace #63
Figure 3 shows a finished controller. The handle on the left-hand side contains a sensor which measures the distance to the target on the handle on the right. The target is connected to a piece of pipe which slides over one connected to the handle. This means that the balance of the controller will change during play, just like a real trombone. It also means that the handle will fall off the end of the trombone if you move it too far, which is just like a real trombone too.

Inside the Globus INK: a mechanical navigation computer for Soviet spaceflight
We recently received a Globus from a collector and opened it up for repair and reverse engineering. In this blog post, I explain how it operated, show its internal mechanisms, and describe what I've learned so far from reverse engineering. The photo below gives an idea of the mechanical complexity of this device, which also has a few relays, solenoids, and other electrical components.

An Open Hardware Automatic Spinning Machine
The team at the Berlin-based Studio HILO has been working on ideas and tools around developing a more open approach to small-scale textile production environments. Leveraging open-source platforms and tools, the team has come up with a simple open hardware spinning machine that can be used for interactive yarn production, right on the desktop. The frame is built with 3030 profile aluminium extrusions, with a handful of 3D printed, and a smidge of laser cut parts. Motion is thanks to, you guessed it, NEMA 17 stepper motors and the once ubiquitous Arduino Mega 2560 plus RAMPS 1.4 combination that many people will be very familiar with.
