Printed It: Do More with Lockable Ball And Socket Helping Hands

In one hand you hold the soldering iron, in the other the solder, and in two more hands the parts you’re trying to solder together. Clearly this is a case where helping hands could be useful.

Luckily helping hands are easy to make, coolant hoses will do the job at under $10. Attach alligator clips to one end, mount them on some sort of base, and you’re done. Alternatively, you can steal the legs from an “octopus” tripod normally used for cell phones. So why would you 3D print them?

One reason is to take advantage of standardized, open source creativity. Anyone can share a model of their design for all to use as is, or to modify for their needs. A case in point is the ball and socket model which I downloaded for a helping hand. I then drew up and printed a magnifying glass holder with a matching socket, made a variation of the ball and socket joint, and came up with a magnetic holder with matching ball. Let’s take  look at what worked well and what didn’t.

Friday Hack Chat: How Do You Collaborate With Hardware?

Our guests for this week’s Hack Chat are Pete Dokter and Toni Klopfenstein of SparkFun Electronics. Pete is formerly the Director of Engineering at SparkFun and now the Brand Ambassador for SparkFun Electronics.

He hosts the According to Pete video series expounding on various engineering principles and seriously needs a silverburst Les Paul and a Sunn Model T. Toni is currently the product development manager at SparkFun. She’s served on the Open Source Hardware Association Board and participates in the Open Hardware Summit yearly. In her free time, she spends fifty weeks out of the year finding dust in her art and electronics projects.

This Is The Last Weekend For The Coin Cell Challenge

This is it. This is the last weekend you’ll have to work on the most explosive battery-powered contest in recent memory. This is the Coin Cell Challenge, and it’s all ending this Monday. You have less than 48 hours to create the most amazing thing powered by a coin cell battery. Joseph Primmer slapped a coin…

LED ring

Jens Hauke designed this charlieplexed 20 LED blinker controlled by an ATTiny45 for the Hackaday Coin Cell Challenge:

156251514462780263

LED Ring

This is a small blinky with 20 LEDs powered by one CR2032 coin cell
and with an ATTiny45 brain. The firmware is written in plain C and
compiled with the avr-gcc toolchain. The PCB is a two layer design made
with KiCad.
Space efficient daisychained LED placing with shared anode/cathode soldering pads.

Firmware and gerbers are available on GitHub:

jensh/attiny-20led-ring

 

Jens has shared the board on OSH Park:

BeagleLogic Standalone featuring the Octavo SiP

BeagleLogic Standalone – Featuring the OSD3358-SM

Three years ago, as a student under the Google Summer of Code program for BeagleBoard.org, I developed BeagleLogic – that turned the BeagleBone Black and its variants into a Logic Analyzer using the Programmable Real-Time Units (PRUs) on the AM335x SoC to capture up to 14 inputs up to 100 MSamples/sec. It is possible to fill up to 300MB of the 512MB DDR RAM in the BeagleBone with logic samples – that’s 3 seconds of data at 8 channels (1.5 secs at 16 channels). I also designed a cape for the system – called the BeagleLogic cape that would allow buffering the external logic signals up to 5V TTL so that they do not damage the BeagleBone.

The launch of Octavo Systems and its OSD3358 SiP got me excited, and the idea of a turnkey version of BeagleLogic was rekindled as the design would be greatly simplified due to the SiP integrating the core components, leaving me to focus on the features I want to add to the system.

beaglelogic-timeline-1024x225

From concept to completion, this project took 4 months working on it part-time. I relocated in August so work happened at an even slower pace during that month

The schematics were originally based on the OSD3358, however Jason encouraged me to design based on the newly announced OSD3358-SM as it was smaller and had a more optimized ballmap. The schematics were then migrated to the OSD3358-SM in late July. At the beginning of the routing exercise, I was really apprehensive if the design could be routed in 4 layers but thanks to the optimized ball map of the OSD3358-SM, the routing was easily completed so.

Reflowduino: Circuit Board Assembly for Everyone

Timothy Woo has launched a Indiegogo campaign to manufacture his open-source, Arduino-compatible, wireless PCB reflow oven controller:

Reflowduino: Circuit Board Assembly for Everyone!

Reflowduino is the first completely open-source, Arduino-compatible reflow oven controller of its kind that enables practically anyone to assemble their own beautiful circuit boards at home!

Reflowduino comes loaded with features, all in a compact Arduino-compatible package, with full documentation, example code, demo app, and comprehensive wiki on Github.

ecriw1wwk9mpio5pmbz4

Reflowduino is designed to be extremely easy to use! The general concept is to switch the power of the appliance on or off with a solid-state relay as shown below, measuring the temperature by placing the thermocouple tip inside the oven during the whole process.

If nothing else, please share this campaign to your friends, family, and anyone who might be interested on social media! Remember that every view counts for me, and I’m depending on you to make this happen!

Silicon Valley Hardware Meetup – Reboot!

Wednesday, Dec 6, 2017, 6:30 PM

Evil Mad Scientist
1285 Forgewood Avenue Sunnyvale, CA

106 Members Attending

It’s been a while since our last Meetup, so it’s time for a reboot!Mark December 6th on your calendars, and come by the new fancy Evil Mad Scientist Laboratories shop for food, non-alcoholic drinks, and talks. Come meet hardware enthusiasts from around the South Bay and Peninsula to show off and discuss projects you are working on. We’ll even hav…

Check out this Meetup →

The first meetup will be the Silicon Valley Hardware Meetup at the Evil Mad Scientist shop in Sunnyvale. It’s going down Wednesday, December 6th, from 6:30 until 9:30. At least some of the Hackaday/Tindie/Supplyframe crew will be there, and the night will be filled with lightning talks, demos, and the cool hardware people you know and love.

Speakers for this meetup will include [Mitch Altman], hacker extraordinaire and owner of far, far too many TV remotes. He’ll be talking about hardware successes and failures in his own businesses. Also headlining the event will be [Clarissa Redwine] from Kickstarter. She’ll be talking about crowdfunding hardware, and the fact that making a thousand of something is a million times harder than making one of something.

62 Hardware Developers Attending

Tonight, we’re featuring talks by people who are working on making electronics design more accessible.We welcome Tiffany Tseng, lead UX designer at Autodesk. Her work supports creators in capturing the design process and she’ll be discussing some of the design decisions behind the Eagle CAD interface. Tiffany has a PhD from the MIT Media Lab, an…

The day after, on December 7th, we’re also going to be opening the doors at the San Francisco Supplyframe office to host the Hardware Developers Didactic Galactic. These Didactics are fun and popular, and you don’t need to go to the South Bay. Food and drink will be served, and there’s a sweet Rick and Morty mural in the alley across the street.

On deck for this month’s Didactic is [Tiffany Tseng], lead UX designer at Autodesk. Her work involves creating and implementing the design decisions that go into Eagle CAD. If you’re wondering why the icons changed a few years ago, she is not the person to talk to; that happened before the Autodesk mothership bought Eagle. If you’re wondering how the awesome push and shove routing actually works, [Tiffany] is the person to talk to.

Also at the Didactic will be [Asaad Kaadan]. He’s a robotics engineer working on cinematic tools for his day job and is currently exploring a very, very cool modular electronics project called Hexabitz. He’ll be talking about Hexabitz and designing for modular electronics.

Look for Drew Fustini in purple at both of these events!
