Tinkerfest in Oakland this April

tinkerfestlanding
Tinkerfest will be at the Chabot Space & Science Center in Oakland on Saturday, April 14th:

Tinkerfest is a one-day festival that celebrates the creative, curious, and innovative spirit in all of us. Tinkerfest brings together makers, artists, and tinkerers to showcase their work while inviting attendees of all ages to join in DIY fun.

During the daylong event, the entire Center will be activated, both interior and exterior spaces, with activities that highlight creativity and curiosity.

A hallmark area of Tinkerfest is the “take apart” zone where tinkerers can see, touch, and learn how something works by assisting in dismantling it. Tinkerfest is geared towards a family audience but intriguing for everyone! The event is a platform for where all ages can experiment and learn together.

Miasma: Classic Dual Voice Eurorack Synthesizer Module

Miasma is a pure analog oscillator module based on the Curtis CEM3340 chips used in legendary ’80s synths, with new & innovative signal patching:Screenshot from 2018-02-17 12-51-02.png

Miasma: Classic Dual Voice Eurorack Synthesizer Module

We designed the Miasma Voltage Controlled Oscillator (VCO) to bring that classic ’80s synthesizer sound back to Eurorack modular systems. We just couldn’t find any currently available oscillators with the sound textures and capabilities that we wanted, so we had to design our own; and now you get to own one as well.  

There are many unique capabilities built into Miasma that you won’t find in any other oscillator module, like the built-in patching and cross modulation structures that make Miasma so flexible in your rack. However, it’s all about the sound – so let’s start with some Miasma audio samples, before we go into the technical details of how we make that sound possible (best listening with Headphones!)

Dock for Onion Omega2

Valerio Backslashnew has designed a small dock for the Onion Omega 2 and 2+:

My Omega 2/2+ dock\new

I needed the smallest dock i could do, that featured:

  • Ethernet
  • Type A USB host
  • Micro USB for power

Here’s what i came up with, i called it dock\new.

layout

It has an onboard linear voltage regulation (i didn’t bother going with a switching one for such low power), magnetics integrated in the RJ45 connector to save space, USB host ESD protection (diode array), USB host PTC fuse.

On the left side there is the RJ45 connector and nothing on the back side of the board, so that you can easily access the MicroSD card on the Omega 2+.

On the right side (the antenna side of the omega) you have the USB type A connector, facing outwards, and the microusb connector for power, facing inwards.

The project is open source (CC-BY-SA 4.0), and the KiCad schematics, board layout and the other files are available on GitHub:

Friday Hack Chat: Making A Makerspace

For this week’s Hack chat, we’re going to be talking all about making a makerspace. These are community hubs where people come together and share resources to bring their inventions to life. It’s not as simple as it may seem. You need insurance, you need a building, you need a landlord who’s cool, and there are a thousand and one things that can go wrong. Who best to steer you through the storm of opening a Hackerspace? Who can you solicit advice from?

Our guests for this week’s Hack Chat are Vaibhav Chhabra, a mech E from Boston University. He spent two years working on an eye diagnostic device, is an instructor at MIT REDX health care innovation lab, and is a founder of the incredible Makers Asylum. Eric Michaud is a Hacker, runner, and author, currently working on Rift Recon, Shellcon, and hackerspaces.org. He has written tutorials on Adafruit, and was a founding member of HacDC before he took off to Chicago and started PS:One.

Magnetic Imager Tile v3.0

 writes in the latest Hackaday Links:

A while ago, [Peter Jansen], the guy who built a tricorder and a laser-cut CT scanner, made a magnetic camera. This Hall Effect camera is a camera for magnetism instead of light. Now, this camera has been fully built and vastly improved. He’s capturing ‘frames’ of magnetism in a spinning fan at 2000 Hz (or FPS, terminology kind of breaks down here), and it’s beautiful.
