Have you wondered how much faster the Raspberry Pi 4 performs than the Raspberry Pi 3 at running computationally intensive TesnorFlow object detection models?
This video gives a performance comparison between the Pi 3B+ and the Pi 4 4GB, showing what framerate is achieved when running TensorFlow and TensorFlow Lite SSD-MobileNet detection models.
It also shows how much faster the models run when using Google’s Coral USB Accelerator.

3D Printing your own thermal insert press.
Thermal inserts are a big thing when it comes to engineering with plastic. They make it easy to use threaded fasteners with plastic parts, and they work great with 3D printing too. There’s a bit of a knack to installing them without damaging your workpiece, however, and [John Culbertson] wanted to make using them as easy as possible. Thus, he created a thermal insert press of his very own!
If you’re not using heat-set inserts with your 3D printed parts you’re missing out. Hackaday’s own [Joshua Vasquez] wrote a great guide on thermal inserts which you heat up to securely melt the plastic as they are pushed into a slightly under-sized hole. While it’s possible to install these inserts by hand, using a press means much more consistent results.
Sipeed Teases Tang Nano Sub-$5 FPGA Development Board with On-Board Programmer
Embedded computing specialist Sipeed has announced final specifications for an ultra-low-cost field-programmable gate array (FPGA) development board, the Tang Nano, which it claims will cost under $5.
Analogue announces the Pocket, an all-new, all-encompassing retro handheld
In what has become somewhat of a yearly tradition, boutique console manufacturer Analogue has just announced another new machine in the works for 2020 and, for the first time, it’s a portable system. Christened the Analogue Pocket, this new system offers a unique take on portable retro gaming that has a lot of potential.
The first main feature on the menu is support for a wide range of portable gaming systems. Out of the box, the focus is on the Game Boy line full support for Game Boy, Game Boy Color and Game Boy Advance. Analogue also promises support for Sega Game Gear, Neo Geo Pocket Color and Atari Lynx using cartridge adapters which, hopefully, won’t fall too far behind the release of the system itself.
A series of mysterious bleeps and bloops defined the early days of the internet
Once upon a time, going onto the internet was a journey through sound. Before all our phones were online all the time, before there were wifi connections in houses, planes, libraries, and coffee shops, we were logged off before we made the conscious decision to log on. Doing so meant listening to familiar dial tones, then a series of mysterious bleeps and bloops, and finally a loud static-y crash that sounded like a radio stuck between stations (if you remember that sound too).
Making a Digital Dashboard! (w/ Google Calendar integration)
Is a plain old paper calendar too boring for you? Well, it is for me! So I built this digital dashboard with live Google calendar and to-do integration.
Linear advance guide – Free and easy print quality improvement
Linear advance is a firmware feature that controls the timing of the extruder separate to the other axes, with a focus on managing pressure inside the nozzle. The result should be more consistent extrusion, especially around corners and other changes of direction. You should also be able to print faster without the quality dropping off so much.

SwarmTouch: Handheld Interaction with Multiple Drones at Once
One drone is easy enough to control, with hours of practice of course, but operating two or more simultaneously is — if not impossible — extremely difficult. As reported here, a team of researchers at Skolkovo Institute of Science and Technology, or Skoltech, in Russia have developed a swarm control system that interfaces with one’s hand and fingertips.
AMD adds the Ryzen 9 3900 and Ryzen 5 3500X to its growing Zen 2 garden
As expected, AMD followed up the recent launch of its Ryzen 9 Pro 3900 CPU for businesses with a non-Pro variant for consumers, the Ryzen 9 3900. It also further fleshed out its latest generation of Zen processors with new Ryzen 5 3500X processor.
We have been anticipating the 3900 part since Biostar tipped its pending launch on its CPU support list a couple of weeks ago. It’s essentially a lower power version of the 3900X, one of the best CPUs for gaming, with slower clocks. It has 12 cores and 24 threads, a 3.1GHz base clock and 4.3GHz boost clock, and 64MB of L3 cache. It also has a 65W TDP.
