Simple Mechanism Gives Support for SMT Assembly

To fight the shakes, you can do one of two things: remove the human, or improve the human. Unable to justify a pick and place robot for the former, [Tom] opted to build a quick hand support for surface-mount work, and the results are impressive considering it’s built entirely of scrap.

It’s just a three-piece arm with standard butt hinges for joints; mounted so the hinge pins are perpendicular to the work surface and fitted with a horizontal hand rest, it constrains movement to a plane above the PCB. A hole in the hand rest for a small vacuum tip allows [Tom] to pick up a part and place it on the board — he reports that the tackiness of the solder paste is enough to remove the SMD from the tip.

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.

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!

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.

Advanced soldering training at Maker Faire Orlando

For the past six years at Maker Faire Orlando, members of FamiLab have taught attendees how to solder with a cool little Makey pin with 2 self-flashing LEDs.  We’ve been asked for more advanced soldering training, and we responded with the addition of a PIC-microcontroller-based board twinkling several LEDs, and with a switch that can be used to change the LED display pattern.

We opted to design the board such that it can be used as a pendant on a necklace (lanyard) or as a keychain (especially for those of you who like large keychains). The design is a scalloped 2.7″ circle with LEDs on the outside circle, and a hole at the top for a keyring. Batteries are on the back of the board.

Workshop: Assembling the Tinusaur Kit in Varna, Bulgaria

This Saturday, September 2nd, we will have one day workshop for assembling the Tinusaur kits for those who supported our Indiegogo crowdfunding campaign. It will take place in Varna, Bulgaria, our host will be VarnaLab – the local hackerspace. We will learn the basics of electronic components, microcontrollers – ATtiny85 in particular and, of course, […]
