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.

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.

DIY Vacuum Pickup Tool

We are always surprised how much useful hacking gear is in the typical craft store. You just have to think outside the box. Need a hot air gun? Think embossing tool. A soldering iron? Check the stained glass section. Magnification gear? Sewing department. We’ve figured out that people who deal with beads use lots of fine…

Surface-Mount Edge Connectors

FacelessTech designed this small board to act as a surface-mount edge connector:

SMD edge connectors

So you want to joint two boards together, You decide to use through hole female and male 2.54 pitch headers. Normally you would use through hole than ether have a 90 degree headers or just bend them over. For years this is how I did it, I would have to make sure I made sure the holes were just the right distance from the edge of the board.

The KiCad design files are available on GitHub:

reDOT: Tiny 5×7 LED matrix

al1 created this remake of the old Texas Instruments TIL305 display with tiny surface mount LEDs:

TIL311 had a alphanumerical brother the TIL305. This was a 5×7 LED matrix in the same form factor

Here is a video of reDOT in action:
