Is there any "Trial" Pro Membership codes?

Hello,  I just stumbled across this site when I was looking for a DIY project off Pinterest and I was wondering if there are any trial offers? There is a PDF I'd like to download for a pallet playhouse for my daughter for this spring and it's so adorable! I wouldn't even mind to pay for one month if that were possible?! I'm just not sure if I would use this site a lot yet to pay for 1-2 years worth. But if I can do a trial it may persuade me otherwise! I would very much appreciate anyone's help this is for my first baby girl who is almost two now and I'm ready to make her spring and summer so much fun but on a budget with this cute pallet play house Thanks!!!!

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, 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. redirects to, while 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.], 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)?

I was just going for a walk, and what do I see? One of those heaters, as shown in the picture.  I immediately saw (pun and hint not intended) the switches, and was anxious to get them home. Unfortunately, I wasn't able to remove the connectors by hand, and didn't have and pliers or wire cutters.  I was 25 meters - less than 5 minutes away from home, and way too lazy to go back and bring some tools. What do I do? Look at the net/grill/cover/protector thing and immediately think that it's sharp and cut through the wires easily, DUH!  Not sure where I got the idea, but I thought that the side, where all of the smaller rods are welded onto the main one, would be pretty sharp. On a second thought, it might not have actually sawed through, but might have ripped through the wires, strand by strand, since it was soft copper. Just thought I'd b̶r̶a̶g̶ share :)

Videos not showing, and cannot remove/ edit videos

Hi troubleshooting team, Here's my info: Windows 8 Firefox 51.0.1 (32-bit) This Instructable, and others I've made, was created many UI revisions ago (back when a "Video Instructable" was a creation option). When I try to load it, a blank space appears where the video should go. There's no way to access the video from the Instructable editor, not even in the HTML. Also, the title image doesn't appear. This appears to only be an issue for Firefox on Windows. I've tried Chrome, Firefox, and Safari on OSX (those work) and MS Edge on Windows (also works). Haven't tried Chrome on Windows. I'd like to know how to be able to remove the video so I can just add YouTube's html code. This is occurring with several of my Instructables. I was alerted to this issue by another user who noticed that a video seemed to be missing, so I feel confident that it's not caused by an issue with my PC. Thanks for looking into this!

USB to Arduino USB Wirelessly?

I am currently working on a robot that has a deadline in about a week, and so far, there is only one problem we haven't solved yet: Communicating with it without a wired connection. Currently, we have a program on a desktop send the Arduino the gcode via USB cable. What we would like to do, is send that information without actually having it connected with a wire. Originally, we were going to have a Bluetooth module connected to the arduino directly, and have the desktop program communicate with it. Unfortunately, due to time constraints, we haven't managed to get it working, and would like to move onto plan B: communicate through the USB port, and essentially leave the Arduino untouched.  I did a little googling, and I wasn't able to figure out very much on Bluetooth dongle -> Bluetooth -> USB that was actually positive and helpful. Currently, we have a few HC06 bluetooth modules lying around, as well as a few spare Arduinos. I was thinking of connecting one of the modules to another arduino, connect that arduino to the robot's arduino, and communicate with the first arduino via the bluetooth. Essentially, the first arduino would be an interface for the second one. Would this work? How would I go about doing it? In short: What would the best method to communicate between a PC and the USB port of an Arduino wirelessly be? Anything helpful is always appreciated, thanks!

Sound location & motion tracking robot head

Hi guys I hope this is ok to ask about as I have followed Instructables for ages but not used the forum part before. I have a bit of experience of arduino projects and doing basic sketches for them but nothing as ambitious as this so am seeking a bit of advice if possible. I'd like to be able to have a droid/robot's head that can rotate to focus on the direction of a sound, then if it sees a person once looking in the direction it heard the sound, to then roughly track them (move its head) with a camera. I'm fine with motorisation and that side of things, but I'm not sure if this sort of fairly elaborate setup would be possible with an arduino or would need something more powerful like a rasp pi? I'd imagine that I would need an array of several mics as inputs around the bot in a 'circle', and code that can estimate the direction by means of the signal strength from the mics when it hears a noise.  I think this might be something I can manage to do, but then it'd need a suitable camera and a means of tracking and I've no idea how the tracking side of things would work with that. I'd be grateful for any pointers to get me going thanks.  It's not something I could do without help but hopefully doing it bit by bit and with some advice I'd be able to do this, as I would really love to make it work! Many thanks! Jim

How to Calculate Viewership

As the statistics page on Instructables has never been particularly reliable, I have used an alternate method to check my viewership for some time. As other people have expressed interest in statistics, I've decided to share how I do it. Overall viewership between two points in time To use this method, you will need to have taken a snapshot of your member page and have logged it into the Internet Archive or recorded the number of views you have attained at a previous date. Compare the number of views between the two dates to figure out the number of views that have occurred during the period between the two recordings. To find average daily views Using the date from the Internet Archive snapshot or your own records, use this to calculate the number of days that have elapsed since the previous entry to find the number of days that have transpired. Divide the difference in viewership between the two dates by the number of days that have gone by to find your average overall daily viewership. To find the average daily views of your instructables Perform the above steps and divide the number of daily views by the number of instructables you have posted. ----------------------------------------- As with most statistics, the figures you will see from these calculations can be skewed. However, they are still good for getting a good general handle on what the situation is for you as far as viewership goes. If you have not used Internet Archive beforehand, it is a harmless way to log this information as well as take a screenshot of something that you and others can look back on at a later date. Statistical use is only one of many this sort of thing can be used for.

Project: bead printer

Hey everyone! My name is Michael and I have a project I'm working on: a fuse beads automatic "printer". After I got my mechanical eng. degree I was looking for a project to prove to myself it was worth it. I guess being a maker was my secret ambition, and I felt I needed some project to be proud of.  While babysitting my little cousins and doing some works with Perler beads, I thought to myself: hey! this is cool- I should try making something bigger! and so, as my works grew larger, I began to wonder- can I make it automatic?   What are fuse beads?  These are small beads made from plastic that come in various colors, and can melt under a regular home iron. Its a kids toy- you place a pattern on a mat, iron it- and get cool results. google it!   What is it supposed to do?  The idea is simple: place individual beads of various colors on a mat full of small spikes according to a pattern. sounds simple, doesn't it? I think its good to first look at a 2 color (black-white) simple scheme and try to print it on a small part of the board. Once the mechanical part is finished, the real programming will start.   Some numbers:  The beads are about 5[mm] in diameter and in height. A typical board is 30X30 spikes. A piece could usually contains 2-10 main colors.   !!STOP!!! Before you read my concept, I would like to know- how would you try to make this project? I have had this idea in my mind for over a year now, and I'm looking for new ideas.   The concept so far: As I've mentioned, its been a long journey already. I am far from having a working prototype and am open to suggestions. The "printer" I designed is similar to a CNC machine: a tube has 15 beads in it. The tube is moved above the board, placing the beads. Refill will be done manually since I wish to prove the mechanics first. I made the printer with Lego and an NXT controller and engines, simply because I had it at home. I tried making a 2 axis motion using a rack and gear (with transmission), moving a tube with beads in it. To my dread, the beads do not like falling off when placed on top of one another (in the tube), so I used a third engine, converting the rotary motion into linear one, applying a small force over the tube to prevent the beads from falling, moving them to the next position, than letting go. I discovered the engines are not as accurate as I would have wanted, and the results are meh. I will add some pictures at a later time as I need to re-assemble it.     Thanks a lot for reading, and I hope we can make this dream come true- lets have some fun!

I didn't think i'd have a problem with choosing some but after searching around the vast majority of switches seem to be rated for AC or 12 or 24VDC and the absolute highest DC rating i've found so far is 28V, the problem is that the highest voltage i'm using is a little under 36VDC so where do i find appropriate switches? I've been getting helpful advice about the speaker project from someone on a forum called SpeakerPlans but they seem to think that i'd be fine using an on/off switch rated at 5A 12VDC despite the higher voltage requirements of my amplifier, i'm not very electronics literate but this doesn't make sense to me and i'm a bit worried about pushing too high a voltage through the switch and perhaps causing a fire or something. I would prefer a rotary switch if possible as i used one on my old 12V speaker and i found that it's a lot less likely to catch on clothes and bodies and break or accidentally turn on while the speaker is being manhandled/transported about. I have 2 circuits in my speaker setup, one is the 36V circuit powering the amplifier/speaker and the other is a 12V circuit powering a small mixer to boost the gain and tweak the sound, assuming i can find a switch capable of handling the 36V is it possible to have one switch that could be wired up to turn on both circuits at the same time?

instructables site: Couldn't see my Drafts after creating new account until logout/login

Hi there, when recently creating a fresh account and trying to create the first draft, i wasn't able to see the drafts in my profile/start page. the draft was however accessible with the direct URL that i used from my browser history once i logged out and logged in (for the first time) again it worked fine for me and i saw the drafts don't know if its a bug or i did something wrong... cheers juergen
