Catch The Eclipse With A Wearable Pinhole Camera

You say you didn’t have enough warning to order eclipse glasses, and now they’re too expensive to buy? Or maybe you did order some but they ended up being those retina-combusting knock-offs, and now you’ve got nothing to protect you during the partial phase of Monday’s eclipse? Don’t dump a ton of money on unobtainium glasses — just stick your head in a cardboard box.

You may end up looking like a Box Troll with the aptly named [audreyobscura]’s box on your head, but it really is a safe and effective way of watching the eclipse, or for gazing at our star anytime for that matter. It’s nothing more than a large pinhole camera, with a tiny hole in a scrap of aluminum soda can acting as an aperture. The pinhole in one end of a box casts a perfect image of the sun on a paper screen at the other end of the box. A hole for your head with a proper gasket around your neck — maybe the neck of an old T-shirt would be a bit more comfortable and light tight? — and you’re ready for the show. The bigger the box, the bigger (and dimmer) the image will be, so you’ll want to cruise the local home center for long boxes. Because walking around with a water heater box on your head is totally cool.

Really, though, Hackaday readers can’t say they didn’t know this was coming. We started covering this in January, we’ve got hundreds of eclipse meetups across the country, and we’ve even covered some citizen science opportunities you can partake in on Eclipse Day. If you don’t have your head in a box, that is.

Thanks to [Roger Guess] for the idea on this one.

Get Your Eclipse Glasses Emblazoned With Hackaday

We’re getting ready to stare at the Sun for a few hours when a total solar eclipse is visible across the United States on August 21st. You could protect your eyes with some welding goggles, but why not wear a pair of Hackaday eclipse glasses instead?

UPDATE: And They’re Gone. We had a huge response to this with over 200 event pages made in just a few hours (and more coming since then; thank you, you’re awesome!). We had 500 glasses to give away and are sending them out in envelopes of 4. We would still love it if you made an event page but unfortunately we’ve run out of glasses to send out.

Let us know where you’ll be watching the eclipse and we’ll mail you some custom-printed Hackaday eclipse glasses (sorry, they’re all gone).  Head over to the Eclipse Meetups page, click the “Host a Meetup” button and tell us where you’ll be. We’ll add you to the map and contact you for the shipping address and the number of glasses you’ll need.

Whether you want others to join you or not is your choice, but we want to see a map full of pins where the Hackaday community is taking part in this momentous event.

As you can see, there are already a number of meetups watch the partial eclipse and that’s fine with us. No matter where you are, if you can see the eclipse we’re ready to send you some glasses. Hurry up though, they need to arrive before Monday!
