Laundry Bot Tackles The Tedium Of T-Shirt Folding

Roomba aside, domestic robots are still in search of the killer app they need to really take off. For the other kind of home automation to succeed, designers are going to have to find the most odious domestic task and make it go away at the push of the button. A T-shirt folding robot is probably a good first step.

First and foremost, hats off to [] for his copious documentation on this project. Not only are complete instructions for building the laundry bot listed, but there’s also a full use-case analysis and even a complete exploration of prior art in the space. [Stefano]’s exhaustive analysis led to a set of stepper-actuated panels, laser-cut from thin plywood, and arranged to make the series of folds needed to take a T-shirt from flat to folded in just a few seconds.

The video below shows the folder in action, and while it’s not especially fast right now, we’ll chalk that up to still being under development. We can see a few areas for improvement; making the panels from acrylic might make the folded shirt slide off the bot better, and pneumatic actuators might make for quicker movements and sharper folds. The challenges to real-world laundry folding are real, but this is a great start, and we’ll be on the lookout for improvements.

2021 Remoticon Shirt

Last Call For Hackaday Remoticon Shirts

Hackaday conferences have a long history of excellent T-shirt designs and this year’s Remoticon is no different. If you want one of your own, you need get on that before Friday. The only way to score on is to buy one of the T-Shirt + General Admission tickets by November 11th — it gets you into all of the conference events just like the free ticket, but also scores you a shirt. (Shipping within the US is free, international delivery costs an additional $10.) What you see above is the actual test print, modeled by Aleksandar Bradic who designed this and all of the shirt from past Hackaday conferences.

Of course the most important thing is that you don’t miss Remoticon, and there is a free ticket which will remain available through the end of the conference, but you can help us with the logistics by getting one now.

The full list of speakers and the schedule is now available on the conference website. We’re delighted to have Elecia White, Keith Thorne, and Jeremy Fielding present keynote talks, and 16 additional speakers on a range of hardware-related topics. (This is notable: we originally planned for a single day of talks but were blow away by all the proposals and doubled the speaking slots!)

You can’t quite rub elbows with all your friends from afar, but you can certainly spend time together in the conference Discord, during the Hacker Trivia (form teams if you like!), at the Bring-a-Hack inside Gather Town, and at the afterparty which will include a live set from DJ Jackalope.

Everyone Who Bought a Shirt, Read This!

If you bought a shirt and have already claimed it using the code we emailed to you, thank you, you are all set.

If you already bought a shirt but haven’t claimed it, check your email. You need to respond to the Google form we sent you. If you bought a T-shirt ticket and didn’t get an email from us, let us know. All shirts need to be claimed by November 15th! Gogogo!

If you plan to order your shirt right now, here’s what will happen. Buy your ticket following the link at the top of this article. We will email you a poll question about domestic or international shipping because we have to use two different ordering interfaces for these — logistics are hard. We will then email you a redemption code and link where you can choose your size and shipping address.

We Appreciate The Patience All of You Have Shown

Thank you to everyone for your amazing patience through this process. We wanted to replicate the experience of walking into Supercon and getting a shirt at the check-in table. Shipping logistics made that a bit harder, but everyone involved has been super awesome about it and that feels really good. See you at Remoticon a week from Friday!

Wearable Breadboard

We all know what a short circuit is, but [Clement Zheng] and [Manasvi Lalwani] want to introduce you to the shirt circuit. Their goal is to help children, teachers and parents explore and learn electronics. The vehicle is a shirt with a breadboard-like pattern of conductors attaching snaps. Circuit elements reside in stiff felt boxes with matching snaps. You can see it all in action in the video below.

We imagine you could cut the felt pieces out by hand with the included patterns. However, they used a laser cutter to produce the “breadboard” and the component containers. Conductive thread is a must, of course, as are some other craft supplies like glue and regular thread.

Cornell Students Have Your Back

Back problems are some of the most common injuries among office workers and other jobs of a white-collar nature. These are injuries that develop over a long period of time and are often caused by poor posture or bad ergonomics. Some of the electrical engineering students at Cornell recognized this problem and used their senior design project to address this issue. [Rohit Jha], [Amanda Pustis], and [Erissa Irani] designed and built a posture correcting device that alerts the wearer whenever their spine isn’t in the ideal position.

The device fits into a tight-fitting shirt. The sensor itself is a flex sensor from Sparkfun which can detect deflections. This data is then read by a PIC32 microcontroller. Feedback for the wearer is done by a vibration motor and a TFT display with a push button. Of course, they didn’t just wire everything up and call it a day; there was a lot of biology research that went into this. The students worked to determine the most ideal posture for a typical person, the best place to put the sensor, and the best type of feedback to send out for a comfortable user experience.

We’re always excited to see the senior design projects from university students. They often push the boundaries of conventional thinking, and that’s exactly the skill that next generation of engineers will need. Be sure to check out the video of the project below, and if you want to see more of this semester’s other projects, we have you covered there tooContinue reading “Cornell Students Have Your Back”

Visual Guide To The Best Hacker T-Shirts

Head out in the normal “civilian” world and look at the shirts around you. I don’t want to be too nasty about about it, but let’s face facts — the T-shirts you see will be boring and uninventive. Now compare that to your favorite hacker cons. We wear our shirts like they’re oil paintings.

Going into the weekend of SuperCon I had no intention of writing this post. But then I saw a really awesome shirt and already had the camera in my hands so I asked if I could snap a picture. A bit later that day it happened again. Then I don’t know what came over me. Here are my favorites, but I’ve curated an epic number of great garments for your viewing pleasure after the break.

New And Improved Old Hackaday Store!

I am going to start off by saying our zazzle store was pretty sad. The prices were just way too high. I put that store into place because frankly, the one I was running was a pain in the butt.

The good news is that I’ve got a new system in place. It is bright and shiny and looks much easier to use. Not only that, but since we’re not using someone like zazzle, we’re keeping the cost down! Or standard shirts are $18. We have stickers too, and this time, we have both standard stickers as well as the custom cut vinyl decals everyone loved before.

Several products have not yet arrived. Since this is the grand opening and I feel a little bad about how expensive the zazzle store was, I’m running a special. $16 for shirts if they’re ordered before August 31st. 

I’m talking to other people about offering some products besides shirts and stickers in the store. Stay tuned to see what we’ve got going on!


[Ben Heck] is in the Halloween spirit with his Portal inspired “see through” t-shirt. That is, a thin lcd is mounted on [Ben’s] chest, with a not as thin camera mounted on his back; when the system is running, everything behind him is captured by the camera and displayed on the LCD. The concept isn’t exactly new by any means, often by the name of “gaping holes” or “hole through body” or more, but the project goes to show that a creative costume isn’t always the most elaborate, expensive, or even a new idea. Catch a video of how to make your own Portal shirt, after the jump. Oh, and you can win the Portal shirt here.
