It's 2016, and Instructables is owned by a big company now. Why does it still not support HTTPS successfully?

(I thought there was a forum for topics about the Instructables website itself, but apparently not, so I'm putting this in Square Pegs.) Posting this publicly poses no risk to the security of the Instructables website or any user's account. Any attacker who would use this information (which is pretty much all of them) would be able to figure it out on their own more easily than finding and reading this post. It is extremely obvious to anyone who simply looks at the address bar while visiting the website. (I would be very surprised to learn that no one has taken advantage of it already, if that can even be proven.) Instructables appears to be severely behind the times when it comes to keeping its users' accounts safe from hacking, and their communications secure from eavesdropping and tampering. Just about everyone who runs a website or is very active online these days knows the importance of having a secure HTTPS connection between your computer and the website's server. (For anyone who hasn't been paying attention for the past ten years or so, here's a Wikipedia article about it.) Like any security-conscious Web user, I'm reluctant to log into any website that doesn't use HTTPS, especially when I'm on an Internet connection that's not my own. (Just look up Firesheep to see why.) In the early years of the Web, HTTPS didn't exist, and every webpage was loaded and every form was submitted insecurely. Then HTTPS was developed. For years, many websites used HTTPS just for their login pages, and used HTTP (i.e. insecure communication) for the rest of the site, once you logged in. This was better than only HTTP because it kept man-in-the-middle attackers from seeing your password, but they could still manipulate the content you saw or the actions you took after logging in, or take over your session using Firesheep. At that time, website operators didn't want to use HTTPS for their entire sites because it would slow down page loading. These days, however, most websites that you can log into use HTTPS for everything, because it's more secure and there's no longer any reason not to. HTTPS is now much faster than HTTP, because it allows more optimization and compression. The only websites I can think of other than Instructables that let you log in insecurely are those that don't support HTTPS at all, mostly small-time forums operated by people without much website administration expertise. It appears that Instructables has made some attempts to support HTTPS, as evidenced by this forum topic from 4 years ago. That was a complaint that the certificate (from Fastly, the CDN Instructables uses) wasn't valid for Instructables and was therefore rejected by the user's Web browser, preventing a secure connection. One of the replies mentioned that a secure login page was available at https://ssl.instructables.com/account/login, and that login page is actually still available. However, it is not linked to from any other page that I can find, meaning that everyone who doesn't know about it (i.e. the vast majority of users) is logging in insecurely, meaning that the sentence "When sensitive personal information is transferred over the Internet, we encrypt it using Transfer [sic] Layer Security (TLS) encryption technology or similar technology." in the Autodesk Privacy Statement is factually incorrect about Instructables. Furthermore, working HTTPS doesn't seem to be available at all for the user account settings, meaning that when a user changes their password, both the old password and the new password are transmitted insecurely, which also makes that sentence incorrect. Additionally, when I try to use HTTPS for any other Instructables page, it doesn't work. https://ssl.instructables.com redirects to https://www.instructables.com, while https://www.instructables.com results in the above mentioned certificate error because the certificate Fastly is using doesn't include Instructables on the list of (many) sites that it's valid for. (I can bypass the certificate error and load Instructables over HTTPS anyway, but this is a bad security practice, and the connection does not stay on HTTPS as I browse, making it pointless.) In summary, Instructables seems five to ten years behind the rest of the Web when it comes to user account security. However, I think this could probably all be solved pretty easily, by asking Fastly to enable (or fix, if it's supposed to be enabled already) HTTPS for the domain [www.]instructables.com, and either changing all links to point to HTTPS URLs or (preferably) enabling HSTS, which will cause all users to use HTTPS regardless of the URLs they type or the links or old bookmarks they click. This would likely have the side benefit of speeding up page loading for all users. --- P.S. The lack of HTTPS has also caused me to worry about another aspect of Instructables account security. The Privacy Statement says nothing about how users' credentials are stored on the server(s) to prevent breaches of sensitive information by malicious attackers, negligence, disgruntled employees, etc. (It only says that employees are only allowed to access users' information if they need to to perform their duties, and that data is securely destroyed when no longer needed.) Does Instructables use industry-standard salted hashing (SHA-1 or better) to keep users' passwords secure on the server(s)?

Led fading aquarium? Answered

Hello, I have a fish tank, and it has a TL light above it. I made blue Led's above the fishtank. My idea was: - You get like from 8 AM. - 8 PM. the TL ligth (or some led's i have to make) - From 8PM-10PM the blue Led's - And then it all shuts off. - And then the cycle goes aroud. But the thing is, the TL is 220V and the leds are powered by a 8V AC powersupply, I made a diode bridge, so it all works, But my TL ligth will just shut off, becose it has a timer on it, And i have to turn on/off the blue leds myself. So, does anyone have an idea how to do this? maby some extra white led's so i can power it from 1 cicuit? Greetings. Ingmar (Im from Holland, don't mind my shitty english)

adaptive making

Alright, fellow Instructablers, I need help. I'm not usually a forum-poster; I like lurking. But I'm getting a little desperate. About a month ago, I was in a bit of a car accident. The airbags went off as I was trying to turn away from the telephone pole, and so my right wrist was in front of the steering wheel when the bags went off. This means that my right wrist (yes, I'm right handed) is still recovering, with the current diagnosis of "soft tissue injury with a sprain on top." I'm going to see a hand specialist, but in the mean time, it's quite the wrist brace. Though I can use my fingers, I can't do much without pain/stiffness/etc. So here's the problem that I'm posing to you: what can I make? I'm going stir-crazy. I knit, I woodwork, I play with wire and jewelry making, I draw, I take things apart... I'm willing to learn any new medium and play with any new toys. But I can't use my wrist. So, what adaptive techniques or simple projects or mediums do you suggest until I'm back to full powers? TL;DR: Can't use my wrist, but want to keep making things. Ideas?

How to take the project off of the arduino board? Answered

So i have been looking for a long time for a way to "take the project off of the arduino board" (unsure what else to call it so that hampers my search) in order to reuse the board without buying a new one, or dissemble the old one each time i do a new project. Then i stumbled upon this instructable https://www.instructables.com/id/Convert-2-LED-Lamp-to-50-Smart-Lamp/ i see how he just used the arduino only to program it. How do you design this circuit?? i was unaware that the pins on the arduino correspond directly with pins on the chip, without extra parts between the chip and the pin. is this correct or am i mistaken? in theory if i have the blink program loaded up on the arduino and then i take the chip out and wire it up with power going to it and the correct leg of the chip wired "directly" to the resistor and LED would that work?   TL;DR I want to be able to program a different IC (assuming the correct model of chip is purchased) and use that in the final project so that i can then reuse the arduino. Are there instructables for this already? and i dont mind doing footwork, i just need to know what to search for.

Why is transistor constantly open with 12V power adapter?

Hello, Having nearly everything done on my latest project I've run into an issue which leaves me clueless. When using a transistor as a switch it's all good when ran in a test mode of single LED powered from arduino, however, when I try using the 12V power supply I have (220->12V converter of 24W) the transistor is always open. No matter if I try to control the strip I will need or a single LED, no matter that I even tried an arduino code which sets the pin connected to transistor base to low, it's still on. Slight blinking can be seen on the LED strip. I've tried both TIP120 and 3904 transistors (didn't exceed the amperage on that), result's the same. I've already tried 2 different power supplies as well. When the arduino is off power - transistor is closed and LEDs are off. I'm simply not able to connect the dots in this case as of now, maybe someone has dealt with a similar issue? TL;DR Same setup with transistor works perfect on arduino power, but always on when fed 12V && arduino is on. Thanks in advance! Going to sleep on it now, maybe will have ideas myself in the morning as well.

555 frequency control another 555 controlling a servo motor.? Answered

Hey guys, I have another question. I'm in the planning stages of a project, It's basically supposed to be an astable 555 sending out a frequency that's supposed to control the mark space ratio of another 555 that's going to send a signal to a servo motor, causing it to oscillate back and forth. Tl;dr, I want to make a servo wiggle around with two 555s. I have used the output of a 555 to modulate another one before, but I understand that using a 555 to control a servo is slightly different than just audio output. So is there anything I should be aware of? Is there anything I can read or look at to point me in the right direction? Thanks. EDIT: I just had an idea. What if I took the output of the first 555 (thus forth referred to as IC1) and used it to turn on a transistor, which connects a resistor in parallel to some part of the IC2 which decreases mark space and turns the servo. https://www.instructables.com/id/Simple-Servo-Tester/ This one uses some pots to control rotation, if a resistor is connected in parallel using a transistor... something will happen. It moves.

Dishwasher spray arm: make/buy and attach to PVC

What I'm trying to accomplish: a usable dishwasher spray arm, that can attach to a PVC pipe, for reasonably cheap. I'm not against buying one, and I've looked at this one, which is snap-on, and this one, which has a nicer price but it's hard to tell how exactly it might work (or more likely, not work). I mean, how would you ever attach that to PVC? And the former is a little on the expensive side. I've also thought of making one out of PVC, since you could easily drill small holes in a piece of PVC pipe and stick them onto a T. But that has the problem of not being able to spin at all, much less spin on its own. I have searched long and hard and have not been able to find any sort of rotary union that would work (and I'm afraid even if I did, it may not allow free passage of water). A solution for spinning on its own may be as simple as making the pipes "bent," so the water would force it to spin as it goes around the corner. TL;DR: How can I make/buy a dishwasher spray arm that can attach to PVC (actually two of them)? And in case you're wondering, yes, this is for a dishwasher (DIY). Thanks for the help!

My laptop won't connect to my Home Wifi?

Hello, My laptop won't connect to my home wifi. The problem just started few weeks ago, before it was automatically connecting to it with no problem. I have a broadband router, wifi enabled with TP Link (TL-WR340G) Wifi router. My network won't even show up in the available networks list. However, if I reboot the machines or turn on or off my router or broadband router, it somethings catches it and it works fine. I don't know what thing make it works (it automatically connects). Sometimes, it just catches the signal (but don't connect automatically as I have set my home network on auto connect), but when I connect it manually, it don't get connected, instead it shows troubleshooting. And troubleshooting always lead  me to "reset your modem by turning it off for 10 seconds", and nothing happens when i do this. Few things I should mention: 1. My laptop connects perfectly with other wireless networks. After this problem,  I mostly use my neighbour's wifi, that works perfectly everything. 2. My wifi router works perfectly with my iphone, and other wifi mobile devices. The problem is only with my laptop. Please guide me, whats wrong and how to solve it.

You might or might not have noticed me, for even though I've been here for so long I have only posted 17 instructables (almost all of them Knex related), with most of them being 'average' to say the least, and most of them were slideshows with incomplete instructions. One of the few things of my that did recieve a lot of positive criticism though, was my Knex dock, designed for my DS. It wasn't all that special, but it sure was one of the best Knex docks out there. And I did win the third place in the Knex contest with it, along with a nice patch. And today I saw it has reached 4.95 stars, which is an amazing rating! Looking at how good the dock was, I decided to design another dock. But not for a DS this time. I was thinking of a dock for a book. I like reading a lot, and I figured out it would be easier to read if I had a dock with it. No need to put your finger on the pages, easier holding, reading handsfree. Plus, Knex docks have in my opinion a very high coolness-factor. :-D But before I start, I want to know; is it worth trying? Is there anyone who is interested in this? Would anyone want to build it? Are there many book readers and knexers on Instructables? tl;dr, I'm making a knex dock. Interesting, yes or no?

Laptop LCD Cold Cathode re-use

So recently, an old laptop of mine died. It was an old dinosaur of a laptop, slowly running down the remaining years of its life. Then it died. So sad. To honor its death I dismantled it. I got an interesting motherboard, some decent speakers, a 5gb harddrive along with a floppy and disk drive. What really interested me the most though is the LCD screen. At first I hoped that I could re-used the screen as a tertiary screen for my desktop, but later I realized the near-impossibility of this task and gave it up. Instead I chose to take the screen apart for its cold cathode lamp. It's almost 12 inches in length, and very thin. Before the motherboard died, the LCD back light was still working. So I wanted to take it out, along with its inverter, to attempt to re-use it. Soon after doing this I saw a problem in my plans: the input of the inverter is a whopping nine wires. This is a bit more than I'm used to dealing with for power supplies. I was wondering if you guys knew any way that I could go around this? At request I can most more pictures and model number of the inverter in case you can't read it in the photo. tl;dr - Cold cathode inverter in picture. output is two wires, input 9 wires.

Should I ground my amplifier? Answered

This needs a bit of background info. I found this amplifier a year ago in the streets, by the trash, and I took it with me cause I like to open up things and see what I could get (it was obviously broken). I opened it up, and started looking at the parts. The connections are old-school, first time seeing those. I noticed that one cable was not connected, so I took care of it, and tried to power it up. For my surprise it worked, and I had to secure the plug, which had only red and black (+ & - I guess). Fast forward to now, I heard or read that anything connected to a plug should have the ground as well, especially if it had something metal. The amplifier is made of metal on the sides. I'm giving it to my uncle, but I don't want to give him in a dangerous state, so, should I change the plug again and put one with the 3 wires? How or where do I connect the ground? (I saw one connected to a screw in the metal part once) And most important, why? Thanks a lot, sorry for length and for possible grammar or vocabulary mistakes. TL;DR: Found an amplifier without plug, should I put one with ground? How? Where? and Why? THANKS!! I've got answers saying that ground on audio systems are complicated and I've been reading but it's so confusing, and I don't understand it pretty well...

Well this " I like x " thing became complicated Answered

TL;DR version at the bottom, below the line Oh you know, just one of those " I like x " situations, except with a twist. So yeah, I like this girl, we talk for short the small short talk (lasts for about 0.8 seconds). She might know that I have a crush on her (since about 30% of the class knows, of which 80% are friends with this person), but I'm uncertain. Either way, I'm not shy about that. The problem lies in the fact that the 24% of the class that's friends with her knows. Normally, they're always with / around her, which makes talking with her (in the first place) already challenging. Imagine maybe 4 people interrupting your conversation only 2 seconds in. It's like trying to play a video game with the worst ping ever; your talk getting interrupted and all. I would just like to have a chat with her that lasts over 15 seconds, at least, that doesn't involve official business (all talks with her so far involved school projects and such). To my assessment, she's astoundingly similar yet the opposite of me... She's simple, yet highly organized (that's me). She doesn't wanna stand out (like me). Generally silent, shy and reserved (somewhat like me, most of the time anyways). Now here's the part I would like to relate to, but I don't know how: music. She plays the piano, and I play the violin. Now, these are performing arts; you perform these in front of people. We don't play the same instruments, therefore we can't talk about it. Composing a piece? Not a chance. That's my work mode wherein I become secluded from the world (bad impression). Intention: I would just like to make friends, thank you very much (did it last year, too, though without the complications) Age: 13 turning 14 (me) and she's 13 More details: -Freshmen -I can control myself, thank you Additionally: I don't know if she likes me or not. I just need to become friends with her to clear some things up and... make more friends? I'm not bringing my hopes up, though. I have an opportunity to start off our friendship (which is due in less than a week), since we have this Christmas party going and we're supposed to have a gift exchange with a "randomly chosen" person which is done by just pulling out folded pieces of paper and.. yeah, there's the name. The wishlist is simple, yet a tad pricey (just roughly $10, but compared to my allowance). This is getting too long Questions: -How do I make friends now? -How do I sustain this? I'm not good at making friends. I either attract them to me or it was a need that developed. __________________________________________________________________________________________________________ TL;DR version: I like a girl and I want to make friends with her, but then I can't talk with her because of massive external social pressure from her ever-present friends that know I have a crush on her. How can I approach her and sustain our friendship? Thank you.

Ingenuity in the cannabis community

This is an inquiry aimed at the moderators and staff of the site specifically, but should also involve the community. I live in Northern California, which is one of the world centers of marijuana use and culture. My entire life I have been exposed to users of the drug, and it is a drug, although a largely harmless one in comparison to other legal drugs (and let's not make this a debate, please. it's not the issue at hand, argue about that in other places PLEASE). I would also like to add that I do not, never have, and will most likely never smoke marijuana unless I develop a medical condition for which it is prescribed. Being a maker, I have noticed the large amount of art, ingenuity, and design that goes into the smoking devices that these people use. This creativity and design is something that I feel should be shared on this site. Marijuana is a drug that is legal in many places, either freely available or medicinally, or in a legal gray area. In fact, it seems much more legal, and arguably safer than a portion of the projects on this website. From the perspective of someone who does dumb things safely, I have seen some stuff on here that is terrifying at worst, and dumb at best. That said, it's all usually creative, and awesome, and is by no means representative of the vast majority of content on this site. tl;dr: marijuana apparatus can be very creative and artistic, values supported by this site it is legal in various areas and a lot safer than some things I have seen on here The actual question: What is the official position of the mods/staff/community on posting content including or related to marijuana smoking apparatus? I have made many different kinds of smoking things for my friends, and it is a much more in depth and scientific process than one would imagine. If it's okay, I would like to share some of these creations. also, that's not my picture, just an example of an intricate bong.

Basic circuitry help? [not yet resolved]

(I wasn't sure if this should be a comment on the Instructable or not, as it is a bit long, and I have some pictures..) I am following a sound-reactive LE 1.D tutorial and having a bit of trouble. The circuit consists of a SPDT switch, resistor, LED, transistor, and a 3.5mm stereo jack. When I play music using this stereo jack, I get no response from the LED. I'm trying to make something on a breadboard for the first time, so I'm thinking maybe I'm missing something because of that. Here's how the machine is supposed to work: - Positive charge flows to SPDT switch, and if it's in the correct state, continues to the 150 ohm resistor - Anode of LED is connected to the resistor, and the cathode is connected to the "emitter" lead of a TIP31 transistor ("base" is wired to the power bus) - The "collector" lead of the transistor is attached to one of the outputs on the stereo jack - The ground wire on the stereo jack returns to the common lead of the SPDT switch. Perhaps I wired something wrong? I've included pictures if the description is not sufficient. EDIT: I've modified the circuit a bit - maybe I can take pictures / draw a diagram tomorrow. Now, here's how it works: - Positive charge flows from positive side of the power bus to the "base" lead of the transistor - Collector lead of the transistor is connected to the left-channel lead of the stereo jack (also, the ground pin of the stereo jack is connected to the negative side of the power bus) - Emitter lead of the transistor is connected to a 150-ohm resistor - Resistor is connected in series with two LEDs - The cathode lead of the second LED returns to the negative lead of the power bus The LEDs do turn on now, but that's the problem - they are always at full brightness no matter the volume of the music. Even if no music is playing, the LEDs are fully lit. I've used a multimeter to check what's happening, and after pressing the negative lead of the multimeter to the cathode lead, and the positive lead to the anode lead, it shows a constant voltage of 1.986 V. I don't understand how this isn't working - I've verified that the collector lead is correctly connected to the left-channel wire... maybe I should try the right channel? Or a different cable? tl;dr: Rewired and the LEDs are always at full brightness. Transistor doesn't seem to be affecting the emitter output, for some reason..

Advice on A centrifugal pump.

Hello, I recently was given a pet from a friend and after doing some research on what the little guy needs I came to the understanding that the current enclosure he is in is inadequate for his needs. Therefore, I wanted to save up some cash to get him the right size tank set up that I know he deserves. In the meantime though, I have plenty of things laying around the house that I feel could render him a more comfortable habitat till that investment goes through. After more research on the matter, I came to find that for most household aquariums, the bulk of the work falls on your filtration system. That being said, I wanted to go for a Wet / Dry Sump Filter setup as it would be  the most easiest system to setup at home with the various resources laying about. Unfortunately while gravity will be doing the work of siphoning the water from the tank down to the Wet / Dry Filter Media, it will not be moving it back up to the tank. For that I concluded there was no escaping the need of a pump in some shape or form to move that cleaner water back into the tank. From what I read the pump will pretty much determine how big I can make his tank.  So this brings me to my current dilemma. Presented with various motors around the house, I went for the biggest I could find (* excluding the water pumps in our cars mind you). That so happen to be a 1.25 HP Wet & Dry Shop vac that was collecting dust in the garage. I confirmed the motor is working and already came with the impeller attached to it. I was hoping to see if you fine folks could share some wisdom on how I can: 1.) Make it Waterproof. 2.) Adhere the right type of casing around the Impeller and Motor so as to benefit from the  Bernoulli's principle and get the most water moving through my system.  3.) I intend to have this setup not 15~20 feet from where I sleep, this motor is LOUD. I was reading online about creating a sound damping box for it and was wondering what suggestions you guys might have for that? I keep fearing there won't be enough ventilation and it will over heat. ....anything else you would like to throw in. TL;DR :

Emotional Whipsaw Just a personal Blog type post.

This post serves no purpose but to allow me to verbalize my last week, read at your own peril. Man what a strange 10 days it's been. Ten days ago I was going into final with a statistical fail in both my classes. If you're not familiar with grading practices in grad school, a C is a fail. If your GPA drops below 3.0 you lose your eligibility for financial aid, if you get more than two C's you're out of the program. Finals didn't feel like they went well. You can imagine how I felt waiting for grades, here I was, no job, looking like I was going to flunk out. Well, grades came out Thursday, I got B's, not brilliant, but it keeps me in school. That felt pretty good. Friday, I took my wife and her coworker lunch, something I do once a month just for fun.  At least this time I could deflect questions about the eternal job hunt with talk about grades. Got home from lunch and the phone rings......... " Mr.Animal, after a review of the applicants, we consider you the best candidate for the position of..... at....... and you like to extend an offer of employment." Woot! I'm on top of the world, nothing could bring me down.... Except... Except, My wife's dog looks funny, she's all hunched up and whimpering.  I've had enough animals to know that means a back injury.  It's 5, I call the vet, we discuss the maximum I can dope her up and make an appointment for the morning. Except, it's pretty clear by 8pm that she's in so much pain, that she can't even sit or lay down. Have you ever spent 12 hours trying to support the weight of a 60 lb dog? It's a novel experience, by 4 am I was near delirious. After an eternity, morning came. Doc diagnoses a slipped disk. Shoots her full of morphine and gives us a prescription for valium.  She can actually lay down when we get home.  36 hour she's much improved, but has a long way to go. TL;DR Passed classes got job dog sick

Year-to-Data, March 2014

Tl;dr: Check out this pie chart that shows the distribution of projects published in 2014 by category. The outer ring shows the channel within the category that had the highest volume of entries, along with the year to date project count. Do you ever wonder how the projects on Instructables are distributed across categories? I did, too. In a tenuous-at-best connection to the Pi Day Pie Contest, we made a pie chart showing where all the newly-published projects have been categorized since the start of 2014. That outside ring shows the most popular channels within the category, along with a project count for each. Some quick observations: (1) There isn’t as much food as I would have thought. It seems like people are posting food ALL THE TIME, but apparently the overall project volume is coming in via other channels. I guess we’re just getting a lot of good food entries that are being featured more often. The quality of authors’ food photography is getting very good, and the featuring team may be featuring projects under the influence of hunger. (2) Contests drive some (but not all) project builds. Since the start of the year, we’ve run paracord, organization, electronics, and crafting contests. And, wouldn’t you know it, those are the channels receiving the bulk of new projects. Even without a special contest, the Toys channel received an outsized number of projects, so we’ll see what happens later this year when we run a few contests around toys. (Pro-tip: Start stockpiling LEGO and KNEX pieces.) (3) Technology and Living make up just over half of the site’s new content. Sure, the robot has a strong preference for electronics projects, but we’re seeing a lot of great craft projects coming in as well. Either way, an army of hot-tool wielding* makers are creating some really cool stuff. (4) This community may be a little paranoid, but we’re prepared. Paracord and survival projects account for almost all of the outdoor projects we’ve seen so far this year. If I’m stuck in a rural farmhouse surrounded by zombies, I want some of you all right there with me. If you’re worried about the imminent collapse of civilization and are concerned that Instructables won't be around to help with the power out, you can buy a book of some of our best homesteading projects. You’ll be sitting pretty with a chicken coop and some rain barrels while everyone else gets punched over a can of soup. (Don't get punched over a can of soup.) (5) Did you notice anything interesting? Sound off in the comments. I've got some 3 month pro memberships to give away to insightful commenters. :D *or hot, tool-wielding authors.

To Pier 9, Thanks for Everything !

Tl;dr : 1. people are the greatest resource at the pier 2. sometimes it’s hard to work due to too much awesomeness Seriously. Me and my collaborator, Radamés Ajna, had a couple of projects we wanted to do in the spring/summer of 2014, and while looking for some shop space in Oakland, someone recommended we check out the AiR program. We applied. We thought that if we got accepted Autodesk would give us a desk, some nice hand tools, and access to their software. And that would’ve been great. Coming from Brazil, where it feels like we solve everything using hot glue, zip ties and duct tape, that would have been more than enough. Weren’t we surprised when we visited the shop. . . Holy crap, everything is here. Some of the machines are bigger than my apartment, and there’s even a swimming pool ! I’m pretty sure everyone has written about all the great machines, because, yeah, they are great, but to me, the most important aspect of being an AiR at the pier was the people. The shop staff who not only teach you how to use the machines, but also have enough collective experience to help you solve any kind of material/machining/construction problem. Want to vacuum form foam? No problem. Want to glue glass to cement? Someone has done it before. Want to weld titanium? Easy. Having access to the tools is good, but having people that know how to use them is even more awesomenest. The same is true for the CAD people who help you set up and use all kinds of modeling and design software. Not only that, but they get excited when you use their software. Not having had a lot of experience with 3D modeling prior to my residency, it was a great opportunity to learn it using Fusion 360. Another very special group of people were the other AiRs. The ones that came in with us (Anouk, Alex, U-Ram, Adrien, Paolo, Scott, Mikaela) and the ones that were already there when we  arrived (Andy, Aaron, Rima, Andreas, Ben). What a diverse crowd. It was great to get to know everybody, and also to be able to share experiences and expertise. I don’t even know how many times Paolo and Andy saved me from searching for “metal thing with a hole” or “thing with a thing inside” on google, because they knew exactly what I was looking for. Invaluable! Sometimes it’s a bit tricky to explain your project and get everyone excited about it, because everyone has such a diverse background and set of interests, but learning how to talk about our projects from different perspectives was a challenge that I enjoyed. And, last but not least, the IRL Instructables community; another very diverse, active and enthusiastic group of people at the pier. I don’t know how they do it, but it seems like they are always happy, and making cookies. The sum of all of these people is something awesome. There’s always something interesting going on at the Pier (even at night and on the weekends), which sometimes can be a bit distracting, but also motivating. I will sorely surely miss them all.
