Ada Lovelace Fellowship


Apply to the Ada Lovelace Fellowship for 2018 Open Hardware Summit:

Ada Lovelace Fellowship

The Ada Lovelace Fellowship was founded in 2013 prior to the annual Open Hardware Summit at MIT by Summit Chair Addie Wagenknecht and OSHWA Director Alicia Gibb as a way to encourage women, LGTBA+ and/or other minorities in open technology and culture to actively participate and foster a more diverse community within open source.

For the sixth year, we are excited to offer up to ten Open Hardware Fellowships to members of the community which includes a $500 travel stipend and entrance to the Open Hardware Summit.

By offering the annual travel and summit conference assistance to community members, the Open Source Hardware Association hopes we as a community can encourage more women, LGBTA+ and/or people of color to participate in open source. We have many strong leaders and speakers in our field and we personally want to continue the trend upward.

This is a crucial time in open source where we have the opportunity to shape the future of the whole field together. We invite you to contact us about sponsoring. We are just on the edge of what is possible, Let’s be the change!

DIY 5V-3V Switching Converter in the Space of a TO-220 Package

From  on the Hackaday blog:

DIY 5V-3V Switching Converter in the Space of a TO-220 Package

We’re suckers for miniaturization projects. Stuff anything into a small enough package and you’ve probably got our attention. Make that something both tiny and useful, like this 5-volt to 3.3-volt converter in a TO-220 sized package, and that’s something to get excited about. It’s a switch mode power supply that takes the same space as a traditional linear regulator.

Granted, the heavy lifting in [Kevin Hubbard]’s diminutive buck converter is done by a PAM2305 DC-DC step-down converter chip which needs only a few supporting components. But the engineering [Kevin] put into this to squeeze everything onto a scrap of PCB 9-mm on a side is impressive. The largest passive on the board is the inductor in 0805. Everything else is in 0603, so you’ll be putting your SMD soldering skills to the test if you decide to make this. Check the video after the break for a speedrun through the hand soldering process

The total BOM including the open-source PCB only runs a buck or two, and the end result is a supply with steady 750-mA output that can handle a 1-A surge for five seconds. We wonder if a small heatsink tab might not help that; along with some black epoxy potting, it would at least complete the TO-220 look.

[Kevin]’s Black Mesa Labs has a history of turning out interesting projects, from a legit video card for Arduino to a 100-watt hotplate for reflow work that’s the size of a silver dollar. We’re looking forward to whatever’s next — assuming we can see it.

Midwest RepRap Fest this weekend

11The world’s biggest open source hardware 3-D printer festival is this weekend in Goshen, Indiana (USA):


2018 Midwest RepRap Festival (MRRF)

Friday, March 23, 2018 at 3:00 PM  Sunday, March 25, 2018 at 6:00 PM (EDT)

What is MRRF?   It’s the worlds largest celebration of open source 3D printing with over 1,000 people from around the globe attending in 2017.   If you are a hobbyists, enthusiast or any level of user of 3D printing then come on out and enjoy the weekend with others.  Not sure what 3D printing is or want to learn more about it?  Perfect!  Come out and see what it’s all about.

Expanding the NeoPixel Project — Rebooting Electronics

Playing with some animations of the single LEDs strip of my NeoPixel board was nice but the thoughts soon come to mind: “It would look better if there were more strips”, “…if there were more strips, how could they be coordinated”, to “Could I still use the ATiny1614?”.

Water Level Sensors, Alexa in a Fish, and Modular Synths During World Create Day

On Saturday we saw a flood of interesting hacks come to life as more than 100 community organized meetups were held for World Create Day. Thank you to all of the organizers who made these events possible, and for everyone who decided to get together and hack. Students Learning Hardware Design in Islamabad, Pakistan The…
