Sunday evening, May 20th, at BJ’s in San Mateo, 6pm to 12am
From Ben James on the Hackaday blog:
There are few scenes in life more moving than the moment the solder paste melts as the component slides smoothly into place. We’re willing to bet the only reason you don’t have a reflow oven is the cost. Why wouldn’t you want one? Fortunately, the vastly cheaper DIY route has become a whole lot easier since the birth of the Reflowduino – an open source controller for reflow ovens.
This Hackaday Prize entry by [Timothy Woo] provides a super quick way to create your own reflow setup, using any cheap means of heating you have lying around. [Tim] uses a toaster oven he paid $21 for, but anything with a suitable thermal mass will do. The hardware of the Reflowduino is all open source and has been very well documented – both on the main hackaday.io page and over on the project’s GitHub.
The board itself is built around the ATMega32u4 and sports an integrated MAX31855 thermocouple interface (for the all-important PID control), LiPo battery charging, a buzzer for alerting you when input is needed, and Bluetooth. Why Bluetooth? An Android app has been developed for easy control of the Reflowduino, and will even graph the temperature profile.
When it comes to controlling the toaster oven/miscellaneous heat source, a “sidekick” board is available, with a solid state relay hooked up to a mains plug. This makes it a breeze to setup any mains appliance for Arduino control.
Hardware Developers Didactic Galactic (HDDG) is tonight at SupplyFrame in San Francisco featuring talks by Roy Jui Liang Hung, Tanya Fish (Pimoroni) and Jason Kridner (BeagleBoard.org Foundation):This HDDG should be an awesome crowd as makers from all over are in the SF Bay Area this weekend for Maker Faire.
(look for our Drew Fustini in purple)
Can’t make it? SupplyFrame will have LIVE STREAM starting at approximately 7:00pm US PDT:
Enjoy delicious food (that is unlikely to be pizza) and beverages while listening to fascinating technical talks by these crazy and creative engineers.
Tanya Fish – Explaining Electronics to the Unitiated
Roy Jui Liang Hung – Mastering Animal Mechanics with the 3D Printer
Jason Kridner – Simplifying Hardware Design with System-in-Package Tech
#HDDG LIVE STREAM –> http://bit.ly/2sPgORW
Tanya Fish (@tanurai) has been working at Pimoroni for the past couple of years, and is on a mission to explain how all their boards work to a wider audience. Hear her discuss the issues of explaining the “invisible magic” to complete beginners at electronics, and how the school system in the UK ill-prepares students for anything beyond building a simple circuit.
Roy is founder of Perkūnas Studio and an artist who’s passionate on tinkering. He first learned about 3Dprint in 2011, teaching himself how to master the machine. He is the most renowned 3DP expert in Taiwan. Roy will be talking about the process he used to make his incredible 3D sculptures, which he will be showing off at Maker Faire this weekend. He will even bring one of them to HDDG!
Jason Kridner is the co-founder and board member of the BeagleBoard.org foundation, and spends a lot of time defining strategy for growing open platform ecosystems. Jason will be talking about simplifying hardware design with system-in-package technology.
After the talks, there will be demos, community announcements, and socializing. If you’d like to give a 2 minute demo/ community announcement, please see the organizers when you arrive to get set up.
A community announcement includes looking for a project partner, a job, offering a project/ job, the announcement of your startup launch, your Crowdfunding pitch, etc.
We’re looking forward to seeing you Thursday, May 17th, at 6:30p!

Part hackathon, part geek social, these biweekly meetings are a time for you to come join others for insight, inspiration or just insanity.
Bring your toys for others to see, or come see what others have been painstakingly chipping away at in their spare time.
Whether it’s code or chips, hacking of all sorts is encouraged. But we also like to hear your crazy ideas, so please come join us and bring your willingness to share your brilliance.
We’ll be the kids with all the coolest stuff on the table. Hope to see you there.
p.s. This event is open to everyone, dork or robot. No ^H membership is required to attend.
Maker Faire Bay Area is this weekend, and the Hackaday and Tindie crew are getting ready to jack some cupcake cars. The Bay Area Maker Faire is one of the greatest gatherings of…
