Ordering from OSH Stencils is now easier

Back in 2019, we added ability to order a stencil for your board design from OSH Stencils:

We have extended that capability so you can order from OSH Stencils based on the paste layers from your past OSH Park orders:

Printed TS100 Case Beats the Heat with a Bearing

As we’ve said many times in the past, the creation of custom cases and enclosures is one of the best and most obvious applications for desktop 3D printing. When armed with even an entry-level printer, your projects will never again have to suffer through the indignity of getting hot glued into a nondescript plastic box. But if you’re printing with basic PLA, you need to be careful that nothing gets too hot inside.

Which was a problem when [Oleg Vint] started work on this 3D printed case for the popular TS100 soldering iron. But with the addition of a standard 608 bearing, the case provides a safe spot for the iron to cool off before it gets buttoned back up for storage. Of course, you can also use the flip-out perch to hold the iron while you’re working.

As [Oleg] explains on the Thingiverse page for the case, he actually blended a few existing projects together to arrive at the final design. Specifically, the idea of using the 608 bearing came from a printable TS100 stand originally designed in 2017 by [MightyNozzle]. Released under Creative Commons, [Oleg] was able to mash the bearing stand together with elements from several other printable TS100 cases to come up with his unique combined solution.

Custom 16×16 matrix display PCB

Erik van Zijst writes about their latest project made with our “After Dark” service:
EdUOhStU0AAK80C
For a previous project I explored what it would take to create a text marquee on an 8×8 LED matrix display without microcontroller, using only 7400 chips, an old EEPROM and breadboard components. Matrix Displays I was interested in using an LED matrix display and I picked up some cheap 8×8 ones on Amazon. medium.com That worked, but 8×8 is very small to do anything interesting and so I wanted to give it another go, create a larger 16×16 panel, design a custom PCB and ultimately hook it up to a microcontroller this time to write some games for it.

iCE Bling FPGA – Beautiful LED Earrings with Lattice iCE40

It’s the same story every year. At the horizon is a loved one’s birthday, or an anniversary, and I want to make them something special. Buying something won’t do. Oh no, I have to design and build it myself. I would then start with a simple idea, and then complicate it progressively to the point where it would take several anniversaries to finish the project.

This time, I wanted to build a pair of earrings for my wife’s birthday. Since I am learning about FPGAs these days, I wanted to incorporate one into the design. Having gotten older and wiser, I decided to enlist help early on. I would focus on the overall design and the programming part, and leave the PCB design and assembly to my trusted friend and engineer Siva.

Jerry Lawson: Father of the Video Game Cartridge

Jerry Lawson was an engineer from New York who had arrived at Fairchild Semiconductor in 1970 after having worked at various companies in the defense electronics industry. Working as part of their customer engagement effort, he achieved prominence in the company by revolutionising the point of contact with the customer using an RV (yes, a camping vehicle) converted as a demonstration lab for Fairchild products. He was lucky enough to be in the right place at the right time to be a member of the famous Homebrew Computer Club, cradle of so much of the later microcomputer industry, which put him at the center of a web of contacts covering the games business as it was in the early 1970s.

Though his employer was not involved in gaming, Jerry got his start in that field as a side project. When his friend Allan Alcorn installed the first Pong machine in Andy Capp’s Tavern it suffered from customers interfering with its coin mechanism to score free plays, so Jerry produced a game cabinet of his own called Demolition Derby that had a more robust system. This led to Fairchild Semiconductor International offering him the chance to start their new video game division, and the road to the Channel F was laid.

[..]

There are many names from the annals of computing history who roll off the tongue. People such as Jobs and Wozniak, Bushnell, Dabney, Sinclair, Miyamoto, or Miner. We should also add Jerry Lawson to that list, as his vision to make one console and sell multiple games, done inexpensively with the use of the PCB edge connector, set the standard for decades to come.

RC2014 backplane constructed with flex PCB

We were exited to see this use of a flex PCB to create a backplane for the RC2014:

RC2014 is a simple 8 bit Z80 based modular computer originally built to run Microsoft BASIC. It is inspired by the home built computers of the late 70s and computer revolution of the early 80s. It is not a clone of anything specific, but there are suggestions of the ZX81, UK101, S100, Superboard II and Apple I in here. It nominally has 8K ROM, 32K RAM, runs at 7.3728MHz and communicates over serial at 115,200 baud.

Alvaro Prieto Walks Through a Year of Chaac Weather Station Designs, Upgrades, and Enhancements

Alvaro Prieto has published a write-up of his latest weather station board, the Chaac v4.0, which adds Bluetooth connectivity to his existing XBee-based design.

The Chaac project has been ongoing for some time: Prieto documented his original efforts to build a weather station a year ago, walking through a range of improvements that went from an nRF52-based Bluetooth Low Energy prototype through to a breakout board for the Nucleo development board, and the integrated Chaac board versions 1.0 through 1.2 — the latter adding in solar panel voltage monitoring.

In the year since, Prieto has been working on upgrading the Chaac design — and has gathered all the improvements into a single write-up, beginning with the Chaac v2.0 which combined the existing XBee-based communication system with an nRF52811 for Bluetooth connectivity.

Printed It: Print-in-Place PCB Gripper

The goal of Printed It is to showcase creations that truly embrace the possibilities offered by desktop 3D printing. The most obvious examples are designs that can be printed quickly and cheaply enough that they’re a valid alternative to commercially available products. But as previous entries into the series have shown, there are also technical considerations. […]

Roboticist Grant Imahara has passed away

We are saddened to read the news today that Grant Imahara has passed away.  Mike Szczys writes more on Hackaday:

We awake this morning to sad news of the premature passing of Grant Imahara at the age of 49 due to a brain aneurysm. Grant was best known for his role on the wildly popular Mythbusters television show on which he starred and built test apparatus for seasons three through twelve. He landed this role because he was a badass hardware hacker as much as he was an on-camera personality.

Grant received his degree in electrical engineering from USC in 1993 and landed a job with Lucasfilm, finding his way onto the Industrial Light and Magic team to work on blockbuster films like the Star Wars prequels (R2-D2 among other practical effects) and sequels to Terminator and The Matrix. Joining the Mythbusters team in 2005 was something of a move to rapid prototyping. Each of the 22-minute episodes operated on a 10-day build and a film cycle in which Grant was often tasked with designing and fabricating test rigs for repeatable testing with tightly controlled parameters.

After leaving the show, Grant pursued several acting opportunities, including the Kickstarter funded web series Star Trek Continues which we reported on back in 2013. But he did return to the myth busting genre with one season of The White Rabbit Project on Netflix. One of the most genuinely geeky appearances Grant made was on an early season of Battlebots where his robot ‘Deadblow’ sported a wicked spiked hammer. Video of his appearance in the quarter-finals is like a time-capsule in hacker history and guaranteed to bring a smile to your face.

Grant Imahara’s legacy is his advocacy of science and engineering. He was a role model who week after week proved that questioning how things work, and testing a hypothesis to find answers is both possible and awesome. At times he did so by celebrating destructive force in the machines and apparatus he built. But it was always done with observance of safety precautions and with a purpose in mind (well, perhaps with the exception of the Battlebots). His message was that robots and engineering are cool, that being a geek means you know what the heck you’re doing, and that we can entertain ourselves through creating. His message lives on through countless kids who have grown up to join engineering teams throughout the world.

Grant was the headliner at the first Hackaday Superconference in San Francisco back in 2015. I’ve embedded the fireside chat below where you can hear in his own words what inspired Grant, along with numerous stories from throughout his life.
