They’re having an open house:
Join us for pizza, beer and tours of our newly remodeled, high-tech facility as we celebrate 14 years in business. Bring your co-workers too!
The Open Hardware Summit is coming on Thursday, September 27th at MIT. OSH Park and Screaming Circuits are producing an electronic conference badge this year for the Summit. The badge features an e-paper display and an ESP32 microcontroller.
All 300 badges assembled by Screaming Circuits have arrived!
Thanks to Duane Benson and the rest of the team at Screaming Circuits for all the support on this project.

Would you believe that you can take a cheap 3D printer and easily convert it into a full function pick and place machine to help assemble your PCBs? No? Well good, because you can’t. A real pick and place needs all kinds of sensors and logic to identify parts, rotate them, make sure everything is aligned, etc, etc. There’s no way you could just bolt all that onto a cheap 3D printer, and let’s not even talk about the lack of closed loop control.
But if you have a very specific use case, namely a PCB that only has a relatively large single part that doesn’t need to be rotated, [Connor Nishijima] might have a solution for you. He bought a $150 USD Monoprice Mini, and with the addition of a few printed parts, was able to build a machine that drastically cuts down the time it takes for him to build his LED boards. Best of all the modification doesn’t involve any permanent changes to the printer, he can just pop off the vacuum attachment when he wants to print something.

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.
Timothy Woo has launched a Indiegogo campaign to manufacture his open-source, Arduino-compatible, wireless PCB reflow oven controller:
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!
We are proud to be a sponsor of this Maker Faire Orlando soldering kit:
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.
Designing pcbs for assembly is easy, right? We just squirt all the footprints onto a board layout, connect all the traces, send out the gerbers and position files, and we’re done–right? Whoa, hold the phone, there, young rogue! Just like we can hack together some working source code with variables named after our best friends, we can also…
