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.
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.
Early Bird tickets for Hackaday Belgrade have just gone on sale, but they will not last long. This is Hackaday’s premier European hardware conference with talks, workshops, great food and drink, entertainment, and a hardware badge for hacking and demos.
Although recent versions of KiCad have made improvements to the way part and footprint libraries are handled, the big upcoming change is that footprint libraries will be installed locally. The Github plugin for library management — a good idea in theory — is no longer the default. Spice simulation is also coming to KiCad. The best demo of the upcoming Spice integration is this relatively old video demonstrating how KiCad turns a schematic into graphs of voltage and current.
The biggest news, however, is the new ability to import Eagle projects. [Wayne] demoed this live on stage, importing an Eagle board and schematic of an Arduino Mega and turning it into a KiCad board and schematic in a matter of seconds. It’s not quite perfect yet, but it’s close and very, very good.
There are, of course, other fancy features that make designing schematics and PCBs easier. Eeschema is getting a better configuration dialog, improved bus and wire dragging, and improved junction handling. Pcbnew is getting rounded rectangle and complex pad shape support, direct export to STEP files, and you’ll soon be able to update the board from the schematic without updating the netlist file. Read that last feature again, slowly. It’s the best news we’ve ever heard.
This project evolved from Splinter, the SMT cordwood project I did last summer/fall. The ring is powered by tiny size 10 hearing aide batteries which should give 4-6 weeks of intermittent use, once I come up with a design that doesn’t break after a few days of wear and update the firmware to put the ATtinyx5 to sleep. The first rev (labelled ‘blink-ring’) used deep red 650nm LEDs. Searching for particular component lengths gave me an excuse to use strange 0508 resistors. And somehow, this is my first Charlieplexing project. Yaay novelty soldering!
One reason is to take advantage of standardized, open source creativity. Anyone can share a model of their design for all to use as is, or to modify for their needs. A case in point is the ball and socket model which I downloaded for a helping hand. I then drew up and printed a magnifying glass holder with a matching socket, made a variation of the ball and socket joint, and came up with a magnetic holder with matching ball. Let’s take look at what worked well and what didn’t.
