We are a hackerspace/makerspace! We're a community workshop where people can come to create prototypes, art, and projects.
We are primarily supported by donations of time and money, and member dues.
During open hours, the public can join us entirely free of charge. But donations are appreciated!
Check our calendar at https://heatsynclabs.org for upcoming events!
We have no paid staff, but our volunteer hosts can answer your questions! Every open hours has a host. If you don't know who today's host is, ask around!
Our discussion board is on Google Groups. The link is on our site at https://heatsynclabs.org
We use the Slack app for chat. The link is on our site at https://heatsynclabs.org
Our tools, our workbenches, our wi-fi... Everything starts out a volunteer seeing something the lab needs, and making it happen!
HeatSync has to pay rent for this space. Your donations help!
Our volunteers run classes and workshops! Check the calendar at https://heatsynclabs.org
Our current Open Hours schedule is Mon-Wed 7pm-10pm, Sat 12pm-5pm. See our calendar at https://heatsynclabs.org
Coffee and Coworking is every Wednesday from 9am-3pm. Bring a laptop and work together!
Only our most trusted, knowledgeable, and helpful members get card access! They are nominated and then voted in.
Want to donate? You'll find boxes around the lab. You'll also see QR codes that will let you donate via Zelle, PayPal, and more!
We can't make your project for you, but you can use our tools! Our volunteers may have helpful knowledge, too!
Using any equipment requires signing a liability waiver. Ask your host for info!
Our laser cutter station features 60 watt and 80 watt cutters! Certification required, check the calendar for classes.
Our laser cutters can cut and etch plywood, acrylic, and more! Certification required, check the calendar for classes.
Vaporwave is the best aesthetic. It's true!
Why is certification required to use our laser cutters? Because you need to know what materials may release toxic gases when cut! (It's a thing!)
Why is certification required to use our laser cutters? Because you need to know what to do if your materials catch fire! (It happens!)
At our vinyl cutter station, you can cut stickers, t-shirt transfers, and more!
Stations in the lab include 3D Printing, Vinyl Cutting, Wood Shop, Metal Shop, and more!
Certification is required prior to using any metalworking tools. Ask your host for more info!

Each station is lovingly maintained by one or more volunteer Station Champions. If you see them, thank them!
Our board is elected by our members. They help keep the lights on and the rent paid. If you see a board member, thank them!
Hack Your Hackerspace is our twice-monthly forum where members vote on proposals, then help clean up the lab!
Our lost and found is on a metal shelf next to the member storage boxes, near the laser cutters. Also try asking on Slack or Google Groups!
We know tools break sometimes! But please notify your host about it immediately!
If you think anything in the lab is unsafe, please notify your host immediately!
Our Bylaws are the rules by which the lab operates. https://wiki.heatsynclabs.org/wiki/Bylaws
How does the lab work? Check our wiki! https://wiki.heatsynclabs.org
There are free public parking lots nearby! https://wiki.heatsynclabs.org/wiki/parking
Everyone in the metal shop must be wearing protective eyewear if any machines are running!
Please keep the floors clear of trip hazards!
Please share photos of your projects with us. We'd love to share them on our social media!

Our First Aid kit is next to the bathrooms.
Flammable chemicals, such as oil-based wood stain, should be stored in the flammables lockers near the kitchen.
Please clean up your trash, but especially food trash! We don't want any smells (or pests)!
We're a makerspace first and a meeting space second. It can get noisy. But please avoid operating loud equipment during scheduled meetups (check the calendar)!
Proposals must be posted to our Google Groups forum 9 days before Hack Your Hackerspace to be eligible for voting.
We provide a friendly and safe environment for all. Please notify your host if you see anyone acting otherwise.

The "phosphor" and "starwars" xscreensaver hacks can read their display text from a program such as fortune, enabling cycling text messages. A Raspberry Pi (as early as a Pi 2) can be configured thus:

$ sudo apt install fortune xscreensaver*
$ sudo systemctl enable ssh
$ sudo systemctl start ssh
$ sudo chmod ugo+rw /usr/share/games/fortunes/

On your main system, create and scp over your custom fortune file:

# The extra "-\n" is for spacing because "phosphor" just crams lines together.
# Can't just use "\n\n" because "phosphor" squashes whitespace.
$ rm my_fortunes; cat my_fortunes.txt | ruby -ne 'puts "-\n#{$_.chomp}\n%\n"' > my_fortunes
$ scp my_fortunes xscreensaver@${pi_ip}:/usr/share/games/fortunes/

On the Pi, create an index file and a link. (You need to use the Pi's own installed strfile for this; other versions may be incompatible!) Then test it.

$ cd /usr/share/games/fortunes/
$ strfile my_fortunes
$ sudo ln -s my_fortunes my_fortunes.u8
$ fortune my_fortunes
I am a line that was in your my_fortunes.txt!

In the file ~/.xscreensaver on the Pi, find this line and change it:

textProgram:    fortune my_fortunes
