The Atomic Pi: Is It Worth It?

Several months ago, a strange Kickstarter project from ‘Team IoT’ appeared that seemed too good to be true. The Atomic Pi was billed as a high-power alternative to the Raspberry Pi, and the specs are amazing. For thirty five American buckaroos, you get a single board computer with an Intel processor. You get 16 Gigs of eMMC Flash, more than enough for a basic Linux system and even a cut-down version of Windows 10. You have WiFi, you have Bluetooth, you have a real time clock, something so many of the other single board computers forget. The best part? It’s only thirty five dollars.

Naturally, people lost their minds. There are many challengers to the Raspberry Pi, but nothing so far can beat the Pi on both price and performance. Could the Atomic Pi be the single board computer that finally brings the folks from Cambridge to their knees? Is this the computer that will revolutionize STEM education, get on a postage stamp, and sell tens of millions of units?

No. The answer is no. While I’m not allowed to call the Atomic Pi “literal garbage” because our editors insist on the technicality that it’s “surplus” because they were purchased before they hit the trash cans, there will be no community built around this thirty five dollar single board computer. This is a piece of electronic flotsam that will go down in history right next to the Ouya console. There will be no new Atomic Pis made, and I highly doubt there will ever be any software updates. Come throw your money away on silicon, fiberglass and metal detritus! Or maybe you have a use for this thing. Meet the Atomic Pi!

Assessing Nozzle Wear In 3D-Printers

How worn are your nozzles? It’s a legitimate question, so [Stefan] set out to find out just how bad 3D-printer nozzle wear can get. The answer, as always, is “It depends,” but exploring the issue turns out to be an interesting trip.

Reasoning that the best place to start is knowing what nozzle wear looks like, [Stefan] began by printing a series of Benchies with brand-new brass nozzles of increasing diameter, to simulate wear. He found that stringing artifacts, interlayer holes, and softening of overhanging edges and details all worsened with increasing nozzle size. Armed with this information, [Stefan] began a torture test of some cheap nozzles with both carbon-fiber filament and a glow-in-the-dark filament, both of which have been reported as nozzle eaters. [Stefan] found that to be the case for at least the carbon-fiber filament, which wore the nozzle to a nub after extruding only 360 grams of material.

Finally, [Stefan] did some destructive testing by cutting used nozzles in half on the mill and looking at them in cross-section. The wear on the nozzle used for carbon-fiber is dramatic, as is the difference between brand-new cheap nozzles and the high-quality parts. Check out the video below and please sound off in the comments if you know how that peculiar spiral profile was machined into the cheap nozzles.

Hats off to [Stefan] for taking the time to explore nozzle wear and sharing his results. He certainly has an eye for analysis; we’ve covered his technique for breaking down 3D-printing costs in [Donald Papp]’s  “Life on Contract” series.

Infineon Buys Cypress For $10B

Infineon will acquire Cypress Semiconductors for nearly $10 Billion dollars. This is the latest merger or acquisition in the semiconductor industry, and these mergers and acquisitions show no sign of stopping anytime soon.

Infineon’s market currently consists mostly of products aimed at the automotive market and power management and control. Cypress, likewise, has a wide portfolio of automotive electronics, from the guts of instrument clusters to the brains of infotainment systems. The automotive electronics industry is going gangbusters right now, and companies in the market are flush with cash; Infineon acquiring Cypress allows both companies to focus their R&D to develop products for the same market.

As with all mergers and acquisitions, there is the question of what may be lost, or what may go out of production. Cypress is most famous for their PSOC microcontrollers, but for now those uCs, and their CapSense capability, seem safe. Cypress is also noteworthy for manufacturing old-school memories, but again it looks like you’ll still be able to buy these years down the line; in any event, Alliance memory is still around stuffing DRAMs in DIPs.

This acquisition of Cypress by Infineon is one of the largest in recent memory. Apple recently bought a $600 Million stake in Dialog, and Microchip acquired Microsemi for $8.35 Billion. Tesla bought Maxwell Technologies for a mere $218 Million. This deal between Infineon and Cypress puts the company in the upper echelon of recent mergers and acquisitions.
