Cyborg Ring

cordwood + smt + jewelry + blinkies + zinc-air batteries

This project evolved from Splinter, the SMT cordwood project I did last summer/fall. The ring is powered by tiny size 10 hearing aide batteries which should give 4-6 weeks of intermittent use, once I come up with a design that doesn’t break after a few days of wear and update the firmware to put the ATtinyx5 to sleep. The first rev (labelled ‘blink-ring’) used deep red 650nm LEDs. Searching for particular component lengths gave me an excuse to use strange 0508 resistors. And somehow, this is my first Charlieplexing project. Yaay novelty soldering!

Reflowduino: Open Source Reflow Oven Controller

 writes on Hackaday about Timothy Woo’s Reflowduino:


Hackaday Prize Entry: Reflowduino, the Open Source Reflow Oven Controller

Face it — you want a reflow oven. Even the steadiest hands and best eyes only yield “meh” results with a manual iron on SMD boards, and forget about being able to scale up to production. But what controller should you use when you build your oven, and what features should it support? Don’t worry…


Dubbed the Reflowduino for obvious reasons, Timothy Woo’s Hackaday Prize entry has everything you need in a reflow oven controller, and a few things you never knew you needed.

Learn to Surface Mount Solder with Sean Hodgins

Sean Hodgins has a great tutorial on surface mount soldering:


Learn to Surface Mount Solder Using an SMD Challenge PCB

I feel like surface mount soldering has a bad reputation. It can seem daunting to someone who has never tried it. Since a lot of my project involve using surface mount components, I thought it would be a good idea to make something to inspire people to try it out (without risking expensive components or their custom project).


Decide how you want to assemble your SMD Challenge Kit (re, the video) you can choose to use a soldering iron, or a reflow oven. They take about the same amount of time but using the soldering iron can be a little more challenging and doesn’t require a cheap toaster oven.

Apertus SMT workshop at Maker Faire Berlin

The Apertus° open source cinema team will be running a Surface Mount Technology (SMT) workshop at Maker Faire Berlin this weekend in their AXIOM booth #121:

Surface Mount Technology (SMT) Workshop

In the course of attending a lot of fairs and exhibitions, we’ve noticed that our cameras and components attract the attention of people from all walks of life. We’ve found that despite our reassurances, people discovering the world of Open Hardware tend to doubt their capabilities where soldering tiny components by hand is concerned.


This is why we hold Surface Mount Technology workshops – so that with a little confidence, the right tools and some initial guidance from members of our team, anyone can have great fun learning to make their own PCBs. The workshops are very popular and we have visitors designing pendants and earrings with colour LEDs and blinking patterns – which always creates a buzzing atmosphere.

An “Unfortunate” SMD Project

If you like happy, easy to build projects, this is not for you. This is only for people who like to grind their teeth and pull out hair.

Be warned that trying to hand solder a 0201 package may be considered evidence of insanity and get you committed to bad places by your loved ones or arch nemesis.

Hack Your Hot Air Station

It used to be hot air soldering gear was exotic, but not anymore. There are plenty of relatively inexpensive choices. Many of these appear to be the same despite having different brand names and model numbers. One that is common and inexpensive is the 858D. These run about $50. [Gabse] has one and decided to…
