Raspberry Pi Direct: buy RP2040 in bulk from just $0.70

1 Share

Almost exactly a year ago, we launched Raspberry Pi Pico, the first product powered by our own microcontroller, RP2040. Since then, we’ve sold nearly 1.5 million Picos, and thousands of you have used RP2040 in your own electronic projects and products.

Since June, RP2040 has been available through our worldwide network of Approved Resellers, for a single-unit price of $1. This remains the best way to get your hands on the chip for prototyping, and for small- to medium-scale production. But as RP2040 products begin to ramp to scale, and the global semiconductor shortage has transmuted most other microcontrollers into unobtainium, we’ve started to see people asking to buy tens of thousands of chips at a time.

To allow us to serve these customers better, today we’re launching Raspberry Pi Direct.

Raspberry Silicon, direct from Raspberry Pi

Raspberry Pi Direct is an online storefront, which currently sells exactly two products:

  • Reels of 500 RP2040 chips, with a unit price of $0.80
  • Reels of 3,400 RP2040 chips, with a unit price of $0.70

Simply create an account, add products to your basket, and check out as you would do in any online store. We’ll contact you to arrange payment by bank transfer (Raspberry Pi Direct does not support credit or debit card payments), and ship your products once funds clear.

1: Log in
2: Buy your reels
3: Check out
4: Pay your invoice, and wait by the mailbox

Unobtainium no longer

RP2040 is built on a more modern semiconductor process (TSMC 40LP) than most other microcontrollers. As a result, it makes extremely efficient use of scarce silicon wafer supply: each die occupies just 2mm2, and each 300mm wafer yields roughly 21,000 dice. We have sufficient wafer stock on hand to produce 20 million chips, with more on the way.

If you want to build your product on a microcontroller you can actually buy in 2022, RP2040 is your friend. Head on over to Raspberry Pi Direct to get yours today.

Machine Learning Detects Distracted Politicians

2 Shares
People in meeting, with highlights of detected phones and identities

[Dries Depoorter] has a knack for highly technical projects with a solid artistic bent to them, and this piece is no exception. The Flemish Scrollers is a software system that watches live streamed sessions of the Flemish government, and uses Python and machine learning to identify and highlight politicians who pull out phones and start scrolling. The results? Pushed out live on Twitter and Instagram, naturally. The project started back in July 2021, and has been dutifully running ever since, so by now we expect that holding one’s phone where the camera can see it is probably considered a rookie mistake.

This project can also be considered a good example of how to properly handle confidence in results depending on the application. In this case, false negatives (a politician is using a phone, but the software doesn’t detect it properly) are much more acceptable than false positives (a member gets incorrectly identified, or is wrongly called-out for using a mobile device when they are not.)

Keras, an open-source software library, is used for the object detection and facial recognition (GitHub repository for Keras is here.) We’ve seen it used in everything from bat detection to automatic trash sorting, so if you’re interested in machine learning applications, give it a peek.

Acid-Damaged Game Boy Restored

1 Share

The original Game Boy was the greatest selling handheld video game system of all time, only to be surpassed by one of its successors. It still retains the #2 position by a wide margin, but even so, they’re getting along in years now and finding one in perfect working condition might be harder than you think. What’s more likely is you find one that’s missing components, has a malfunctioning screen, or has had its electronics corroded by the battery acid from a decades-old set of AAs.

That latter situation is where [Taylor] found himself and decided on performing a full restoration on this classic. To get started, he removed all of the components from the damaged area so he could see the paths of the traces. After doing some cleaning of the damage and removing the solder mask, he used 30 gauge wire to bridge the damaged parts of the PCB before repopulating all of the parts back to their rightful locations. A few needed to be replaced, but in the end the Game Boy was restored to its former 90s glory.

This build is an excellent example of what can be done with a finely tipped soldering iron while also being a reminder not to leave AA batteries in any devices for extended periods of time. The AA battery was always a weak point for the original Game Boys, so if you decide you want to get rid of batteries of any kind you can build one that does just that.

A DIY CAD Mouse You Can Actually Build

1 Share

When you spend a lot of time on the computer doing certain more specialised tasks (no, we’re not talking about browsing cat memes on twitter) you start to think that your basic trackpad or mouse is, let’s say, lacking a certain something. We think that something may be called ‘usability’ or maybe ease-of-use? Any which way, lots of heavy CAD users gush over their favourite mouse stand-ins, and one particularly interesting class of input devices is the Space Mouse, which is essentially patented up-to-the-hilt and available only from 3DConnexion. But what about open source alternatives you can build yourselves? Enter stage left, the Orbion created by [FaqT0tum.] This simple little build combines an analog joystick with a rotary knob, with a rear button and OLED display on the front completing the user interface.

The idea is pretty straightforward; you setup the firmware with the application you want to use it with, and it emits HID events to the connected PC, replacing the mouse or keyboard input. Since your machine will take input from multiple sources, it doesn’t replace your mouse, it augments it. It may not be very accurate for detailed PCB layout work, but for moving around in a 3D view, or dialling in a video edit, this could be a very useful addition to your workstation, so why not give it a try? The wiring is simple, the parts easily found and cheap, and it’s only a few printed parts! This scribe is already printing the plastics right now, if you listen carefully you might be able to make out the sound of the Lulzbot in background.

There are many other takes on this idea, with varying levels of complexity, like this incredible build from [Ahmsville] that sadly doesn’t make the PCBs available openly, and here’s one we covered earlier mashing the expensive 3DConnexion spacemouse into a keeb.

Thanks [baldpower] for the tip!

For the second time only, Oru is offering its popular origami kayaks in a limited edition black. The Oru Kayak by designer Anton Willis is a compact and lightweight(25 lbs) boat that floats a maximum of 300 pounds, folds like an origami, and fits into a small suitcase. It folds down to a 33 x 14 x 29-inch box that has a padded shoulder strap. It is quick to assemble (only 5 min) and is fast, stable and handles incredibly well. This special edition is offered with a sleek and stealthy black finish, and comes with a carbon paddle, a seat wedge, a waterproof backpack, and a set of float bags. The black package re-launches on Friday January 14th, 2022, so get you order in fast, these things will sell out fast.

Waves of Engraved Lines Texture the Emotional Figures Sculpted by En Iwamura

2 Shares

From hunks of clay, artist En Iwamura (previously) sculpts minimal forms with wildly varied facial expressions that range from shock and surprise to moody contemplation. Etched across the surface of each character are neat pathways of parallel lines, which evoke the clean, sweeping patterns in zen gardens, that are a physical manifestation of the Japanese concept of Ma. The philosophy identifies “the space between the edges, between the beginning and the end, the space and time in which we experience life. Ma is filled with nothing but energy and feeling.”

Although his aesthetic and process remain relatively consistent—Iwarmura is generous about sharing works-in-progress and studio shots on his Instagram—his approach to spatial questions continues to evolve. “My work size has physically got bigger,” he tells Colossal. “That can have (a) different relationship with Ma, either micro (or) macro.”

Iwamura is currently living in Shiga near his hometown of Kyoto, and if you’re in New York, you can see his oversized faces in January at Ross + Kramer Gallery.
