"Bug" - Issue with image importer converting .PNG files to .JPEG

Update: posting this topic further illustrated that something weird is happening with how Instructables handles images. The image as shown above shows both left and right sides with the text blurry. If you click on the image, the left stays blurry (as it should because it was) whereas the text on the right shows clear and sharp. I give up on the root of the problem, but it's frustrating how the image quality gets messed up.I put "bug" in quotations since you never know if it's a bug, unintended side effect, technical limitation or external problem. I'll let Instructables be the judge. Regardless, I thought it might be worth bringing attention to since I'm probably not the only one to have experienced it.While I use RAW images converted to JPEGs in Lightroom for my main project images, which tend to look beautifully, I normally use Canva to design my title images. Mainly due to being able to add text, shapes or any other elements in layers. Canva exports by default in .PNG format, which is probably the most popular image format after .JPG due to its support of transparencies and lossless compression. For that reason it's normally preferred for header images and graphics. I tend to use a ratio of between 4:3 and 16:9 to make things easier for the file uploader, as well as a longest edge of 1024px since that looks like it's what Instructables wants so it won't be resized. Despite trying to make things easy for the uploader, my title images have always been the blurriest, noticeably more so than the rest of the images or the image uploaded. Today I finally did some tests and found out that on import of .PNG files, the uploader noticeably deteriorates the quality of the image when converting it to JPEG, even if it isn't resizing it. A picture is attached as evidence. It seems to particularly affect portions which are highly saturated or text, greatly desharpening it. It makes a good image look like it's been carelessly edited. For the image to maintain its quality, I have to take the original .PNG and convert to .JPEG on my own (Photoshop), and then upload the .JPEG to Instructables (instead of the .PNG). As a user, what I'd optimally like to see done is: Fix the importer to properly support .PNG images without deteriorating the images. It is way too popular a format to not accept. I do realize it might be a Canva color space or other such issue, but it probably wouldn't be limited to that program anyway. Nonetheless, if this isn't possible, I'd be happy for the system to simply not accept .PNG and to throw-out an error message telling me to convert the images on my own and only upload .JPG. That would at least avoid image quality being inadvertently affected. Make available an up to date FAQ page where all information regarding images is available: what formats are natively accepted, what is the optimal ratio for images, what is the optimal resolution for images, to what sizes an image is resized on import, or any other relevant technical image details. I've researched this multiple times in the past and there are a lot of people with the same questions in the forum. Especially when it comes to sizes and ratios (cut off images, etc). Most of the information is from years ago (ex. 2010) and cannot be trusted to be up to date. Up to now I've uploaded plenty of 18 megapixel images when it is unnecessary given that the largest size shown, I think, is "LARGE" size at 1024px (I believe). A place to educate ourselves objectively on this particular site's preferences would be appreciated.Anyway, thought I'd comment this since it was a relief to finally find out the origin of the problem.

Help! My low voltage, outdoor lighting wont light up - transformer error codes?

I bought a Portfolio 300watt transformer for low voltage outdoor lighting and hooked up a 100' 12 gauge cable (outdoor rated lighting cable) to it. Then I hooked up 4 low voltage lights (12volt 20 watts each). I plugged the transformer in to a gfi outlet that I ran out from the house. And turned it on. The little display flashes "E" and then "1" . The instructions say that the E means that there is a fire hazard so check the circut. So I unhooked every light except one. Same error. I hooked on a different light and unhooked the first one. Same error. Instructions say the cable needs to be under 250'. And the load less than 300w. I am there, except it won't run. Do I have a bad transformer or is there something that I am missing? Oh, and this is to light my haunt in my front yard, so I am running out of time! Thanks for any advice! Matt

Gifs just run once

On the drafts I am writing, I have noticed that the gifs I add run just once when I click on "Full preview". This is the case for the gifs added in the "regular" photo frame, but not for the gifs embed in the text (they are run in infinite loops). And I have the same problem with the last Instructable I have published (https://www.instructables.com/id/Universal-Arduino...), it looks like the gifs are played once then they stop.Is that a bug? I really like to add gifs to my articles to give a better overview of the project, but if they stop after few seconds or even less, I guess no one can see them...Thanks!

Can you help me brainstorm a better way to make a vaulting barrel?

Hi, Thanks for your interest.I want to find someone to make a vaulting barrel. What is a vaulting barrel you may ask? It is a "fake horse" used in the sport of equestrian vaulting , which is gymnastics, essentially, on horseback. There are lots of instructions around involving the welding 55 gallon drums, etc. The problem is these barrels are very heavy and unwieldly. I am not persuaded this this is the best design. I am wondering, for example, could they be made from PVC or something else? Is there a better way to attach the padding? Can the handles be removable easily. The legs, adjustable. I would love to figure out a better approach. Here are the specsspecs (PDF) from the American Vaulting Association and here are some picturespictures.I would appreciate any advice. Thanks so much!muggle

Pin-pointer metal detector front end not working.

Hi,I breadboarded the pin-pointer metal detector and am having trouble with the front end. pcounterA reads 11-14 on the serial port monitor.See previous question on instructibles reproduced below:_________________Asked by jont4e 2 days ago Hi, I bread-boarded your circuit for just the end coils to start, and loaded the sketch. It seems to be pulsing the coil OK but the leds aren't responding nor the buzzer. I uncommented the serial port code and it shows ledthreshold1 always at .97, pcounterA at 12, and calav1 at 81. Is this OK? (The other reported variables are always 1000.) I wound the end coils with some bifilar wire I reclaimed from a microwave HV supply transformer. I assumed that was OK? Do you have a flow chart or description of how the code works so I can troubleshoot? Any help or hints would be greatly appreciated. Jon T 0 Answer from TechKiwi... 2 days ago The pcounterA value should be much higher 200 to 800 at least. My advice is to focus on one channel. Try reversing the polarity of one of the coils as this often is the problem as the pulseIn function needs to have a clean leading edge to trigger the timing process. Ensure your breadboard connections to the coil are short and well grounded. If this does not work direct message me with a link to some photos of your setup and I will try to assist. I'm just building a second unit so your timing is fortuitous as I can provide some test measurements._______________________________Attached are images of the front end scope traces and a shot of the breadboard. Coils are off screen to the left.Swapping coil polarity did not seem to change any waveforms.Hope someone has some suggestions I can try.JT

'Can I connect 2 TPA3118 60w Mono Module to create a Stereo Amplifier?'

This is the only amplifier I had lying around and since it was a mono amplifier, it only accepts 2 inputs. By using two boards at the same time feeding the same signal wherein the LEFT channel and GND goes to the 1st board and the RIGHT channel and same GND to the second board will it work smoothly as a stereo amplifier creating a 120w Amplifier? ~(Also, I'm using only 1 power supply to power the two boards.)

2 months delay in discussion notifications

My "Discussions" tab showed no changes for about two months, and then yesterday it dumped about two months of replies that people had made on my various comments I made on the forums here. I think that qualifies as a bug. I mean, ideally my "Discussions" tab would notifiy me of replies in a matter of hours, so I could reply to those replies in a timely fashion, if it was the sort of thing where someone was expecting a reply from me.I am guessing this problem was maybe related to the recent big "improvements" to the site, to make it more readable for mobile lusers, and other changes to make the site more comment-able, question-able, tip-able, by everyone.Just wondering: Has anyone else experienced this same problem, i.e. a several weeks, or months, delay in notifications of replies to your comments?

Facebook - some things to consider before making full use of it....

As "A last Hurray" so to say I will do it one last time....What am I doing exactly you wonder and why do I bother writing it here?I will write a little story that is spiked with some information that I deem to be worthy to share.And I do bother to show my friends, followers and those who care what might have been a weekly or even daily thing otherwise :)At work recent changes and ongoing problems with our IT systems required that those who need contact with those in charge or above to sign up with Facebook.I tried what I could but Emails appearently don't always show if someone actually ready them and it was down to keeping my job or refusing Facebook.And yes, I tried to raise my concerns about privacy and control of it through the company...Anyway, let us start, shall we?Signing up for Facebook is as easy as asking Google for the name and to follow the obvious links.But those who know me can confirm that I take privacy seriously and that I like to question why someone thinks they need certain information.Which brings me to the point....Anyone these days is on Facebook with one or more accounts - this includes your boss, manager or anyone interested in your name, resume or other background info.Facebook provides just that, the chat and messages are as obsolete as anything else in terms of actually giving you privacy of any kind.When I signed up and was dumb enough to use a well known Email provider for my account details, I was shocked by the following offer.I was asked for my Email password to make signing in and finding friends easier!A quick but endlessly long search through the terms and conditions confirmed that indeed everyone in my contact list would be mis-used for data collecting and referencing - including the content of my Emails.Of course I had to reject this great function several times until Facebook got the massage that I like to keep control over my Email account.Thinking this was already enough for the day I rejected images and other private info, like where I was born, where I worked and such before signing off.Next day I suddenly had a list of friends as long as the shopping list of a childcare centre for thanks giving.At first I though I don't know any of them until I started to do what Facebook wants and looked the people up.Most where contacts I had on long dead messengers like the Yahoo! messenger.You can understand my confusion until I realised I had used the same Emal account for those messengers.Facebook simply reference their records of dead systems with my Email address and was happy to provide friends I really tried to avoid....The hardest hit however was when I realised that even contact backups I did from my mobile, using Google services, appeared.Thankfully most as possible friends but some directly added to my friends list, due to other links they found in their databases.Needless to say that even several of my skype contacts showed up...The last thing that confirmed why I avoided Facebook was the simple fact that all privacy options in the profile are set by default to public!Of course, if you don't mind stripping down your privacy to the entire world while Facebook is using the data for not always legal purposes you shall be fine.But if you only care a little then check the following, hopefully before stripping down:1. Never, ever type your Email password into anything coming from Facebook - no matter what reasons they claim!2. Before you complete your profile with address, phone number or similar, type in nonsense so you can get access to your account settings.After all Facebook does not bother to offer you privacy before you finnish your details and keeps nagging about adding more so they get the vital data they need first....3. Check all account settings in regards who has access!Unless you really want to strip down noone but your friends should have any access to anything.And even for that you should make sure to enable the function to review them before you allow them to show up on your page, history or elsewhere.Things to always keep in mind:1. Your account is not yours as Facebook has all rights to it, you can not even request to have your informations deleted from their databases or remove your account for good.2. Anything your friends see on your page or profile they can share, like or comment on.This means that even if don't like it, it can spread through the community within seconds and as a worst case ruin your life.3. Anything Facebook does or offers, like games, recommendations, things you should know about, have only one goal: To gather more information about you.Like for example using your Google cookies to find out what search for on the web or watch on Youtube....4. Things you like attract more things you might like, again mostly to gather more info about you, your personality, preferences and your friends.Ok, I know!You are using FB for years, have tons of friends there and keep updated about every minute of their life they share...So there is little to no chance to see what I am talking about LOLBut I would not post all this openly without a backup plan ;)If you really dare to challenge me on this then you might have to waste several hours of your precious time, but I think it is worth your time!This is how the game is played:1. Find someone older who does have a vital Email life of sorts but so far no use for Facebook.2. Ask kindly for his support on a test with Facebook that might require him to forawrd correspnding Emails to your account.3. Clearly state that neither his email or FB account will be used to post anything, add friends manually or give out any info the person does not feel confortable to share.4. Point out the possible benefits of having FB with the option to use the persons real name so he can continue using FB after the test if considered a good thing to have.5. If you manage the above successfully then only use the provided name, email and residential address to create a new account.6. Observe and wonder about the things to come.....You will notice that usually quite soon possible friends or persons that could be connected show up.Also that FB will continue to ask about the history, like schools, work, places.If you do an online search on the name often takes less than a week to get a hit refering to FB.The more info about the person you offer FB (with consent!!) the more people will show up to be considered.At this stage and I guess in less than two weeks time after creating the account comes the question about how to continue.Show the person what and who is already present in the created account and if there is an interest to keep the acount for personal use.If so, kindly ask the person to add a friend or more, fill out more details, provide a picture and so on.Hand over full control to the account either by asking the person to change the password and not let you see or know it.Again, ask kindly to get some future updates, screenshot or similar to see how the account evolve, or add yourself as a friend and keep track that way.I do not suggest in any way to create an account without consent!This includes all activities that might seem harmless:Don't use the identity of someone you "found somewhere"!Don't create a fake account, especially not in the name of someone popular or someone that might be harmed in any way by your creation - the person might have good reasons not to appear on FB!If you don't have Facebook already feel free to use to do the test with your own details!Never, ever use pictures that are not your own or that you don't have the explicit permission to use even if you took them!

Awesome stuff you can do with high-speed internet?

So I recently thought up the idea that I can get free high speed internet at the computers at the public library in town (I can only get dial-up at my house). I have to ride my bike a few kilometers to get into town but I can get like 100 KB/s!! Gah, I wish I'd thought of this a long time ago. When I went in yesterday I just downloaded a bunch of crap. I got 60 MB of stuff, mostly podcasts, in about ten minutes. That would've taken me over five hours to get on my dial-up. But is there any thing else that I should try, other than just downloading a buttload of stuff? I've never had broadband, so I'm kinda just dumbfounded by the possibilities.

Variable height desk: replace hand-crank with some kind of electrical motor

Hi, First time poster here, sorry if I'm misplacing this. I have near zero knowledge of engines, though I understand physics, at least from my civil engineering college years. I bought a variable height desk from IKEA (Skarsta model), which has a 12cm radius hand crank (see photos) that ends in a hexagon shape, h=6mm (so diameter around 6,93mm). This hand crank works fairly easily, needing little effort to crank the table up, with ~45kg of weight on it (it's supposed to go up to 50kg). So basically I was thinking if there was a easy, cheap and safe way of automating this with some sort of electric motor (I even looked up those Lego Technic motors!). Any suggestions? Thanks

What 3D printers can do... and what they can't

3D printers have seen insane amounts of attention in the past year with lots of stories coming out about how amazing they are. How they can make replacement parts for anything that breaks. How they’ll revolutionize manufacturing. How everyone will have one and they’ll do everything that you need ever. Long story short, 3D printers are pretty amazing, but they aren’t quite the miracle on a stick that the hype is pushing them to be. So let’s sift through and see what there really is to get excited about right now. Consumer 3D printers AKA what most people will be using The 3D printing that’s available to consumers right now is fused deposition modeling or FDM. These printers build up a model layer by layer by extruding ABS or PLA into the build area. It’s basically a much fancier version of a glue gun. A tiny glue gun controlled by a computer, that is. These 3D printers typically run $1k - $2k, but smaller ones can be had for as little as $200. The MakerBot Replicator 2 is the most popular printer of this kind, but there are dozens of others to choose from as well. With some fiddling and work you can pretty much print any shape that fits inside the build volume. So if the printer can fit it, you can make it. That’s simplifying it a bit (OK, a lot), but that’s the idea, and it’s a very cool idea. After some practice you can learn how to design new things like jewelry, ornaments, or toys. Since everything is printed out you can customize any piece that you’d like. Take a couple hours to learn 123D Design and you’ll start to have new things to print out. That’s the power of 3D printing right there. You can quickly go from an idea to a design and then to reality. Your skills in making things by hand don’t matter here. This is why it’s so amazingly helpful to use a 3D printer for prototyping your ideas. I recently worked on a flash drive case and the first model took about 2 minutes to design. After that it was about 15 minutes to print out on a Replicator 2. Then I tested it and adjusted the design for another print. I repeated the process a few times and within 2 hours I had a file that I was happy with. This is even better considering that I only spent about 20 minutes of those 2 hours actively working. The rest was spent on other non-related work. All about the materials So that’s the power of 3D printing. With services like 3D Creation Systems you can upload your file and get it printed on much fancier machines with better resolution. There’s no immediate gratification, but you still get a high-quality print quickly and access to more materials. Even with this expanded selection of printing materials, it’s still a very limited selection. If we were just to look at all the plastics out there we’d be here for days. There are thousands of them and that’s just plastics. There’s also wood and metal and more beyond that. Each different material in this insanely huge selection has a different quality to it. I’ve seen countless people print out items in ABS or PLA and complain about how their printer must not be working since the printed piece doesn’t work like the original. But of course we can’t recreate every item out there with a couple kinds of plastic. It's about using 3D printing with other tools The key forward in using 3D printing is to use it as an amazing new tool of forming great pieces to work alongside all the other great items and materials out there. Why bother making a weak spring out of plastic when you can drop in a metal spring? So 3D printing isn’t everything, but it can be used alongside most everything. It can get us where we want to go so much faster than before it’s ridiculous. But it’s still not the miracle on a stick, not the only tool we’ll ever need from here on out. When the hype dies down we won’t be looking on at amazement at something being 3D printed, we’ll be looking at lots of awesome new things that were made faster with the help of 3D printing. And that is going to be incredible.

Site Updates: 1/22/2018

Greetings! I'd like to give everybody heads up about some big changes happening on Tuesday (1/23) at 9AM (PST). First off, the Instructables pages are getting a major update. Aside from a sparkly new look, they will now have a section for Questions and Tips. This will provide a place to ask questions when you get stuck, or provide a tip for doing a project better. Secondly, the Community pages (i.e. these forums) are getting a very long-needed makeover. Finally, we are updating our search software, which should improve search results on our site in general. These changes will require a period of downtime on the site of about half an hour. Please check @Instructables on Twitter for updates. Stay tuned for more great changes to come in 2018!

Make their experiences better by coming up with solutions to some real annoyances that hinder their participation. To get you started, here is a specific--and very real--challenge sent to us by project organizers. STOP CRITTERS FROM EATING SUNFLOWERS Background: The Great Sunflower Project uses data collected by citizen scientists to create an online map of bee populations. Participants grow sunflowers, observe how many bees visit those flowers, and then submit their observations. The Problem: Critters, like mice and birds, often eat the sunflower seedlings before the bees are able to visit. As a result, some volunteers are unable to collect and submit data. The Challenge: Create a safe, simple way to ensure the sunflowers are protected from critters and reach maturation. Enter now! Contest closes January 21, 2013

I will only use motors sg90, jumpers, and arduino but I need the arduino code.So I want 4 things to move, you can see all of them in the video. I will then connect it to my computer and use my keyboard for movements. You are free to put any keys you want to control it. Please help asap. This project is for tomorrow for my school. That's why I don't have the time to learn arduino myself right now, if someone could PLEASE help me

Glitches with the Instructables Editor

While trying to make Instructables with the Editor, I have come across two glitches (if this is not the place to report bugs and errors, please inform me).1. The text boxes for the Intro and the Steps editors refuse to let me copy/paste anything into them. The pasted text appears for a split second, then disappears.2. The same thing happens with links. I type in a URL and the text for the link, press OK, will show up for a split second then disappear.I hope this helps to make Instructables a better place.

Adding to Collections

Just wanted to post some feedback. After being away from Instructables for a while, I was trying to figure out how to add an 'ible to my collection, and had to google the answer. I hadn't even noticed the dot menu until that point, even after scrolling up and down the page and refreshing a few times. This process could be made more transparent.

Building: wireless monitor/tablet recycling old laptop parts

Please be positive and constructive with your questions and comments.Building wireless touchscreen ar1100 to bluetooth transmitte by Fearlessleader on Tue Mar 20, 2018 5:04 am Hi I have 15.4 samsung laptop screen I am converting to 4 wire touch overlay and want to us the ar1100 but need to go from the usb out bluetooth wireless mouse transmitter. I would need the same type of transmitter like any bluetooth mouse would have inside. The mini pc I am building has both bluetooth and wireless display.Parts list so far15.4 samsung screen pulled from a Dell laptop modle LTN154W1-L01Control board for the screen with hdmi ebay 30$ link https://www.ebay.com/itm/HDMI-DVI-VGA-LCD-Lvds-Con.. 12v 3 amp power supply for the screen controler I already have but later I would build voltage control unit that would charge or power the whole unit. Again YouTube has videos and links for the part for this. And I really don't want to have a bunch a supplies to run it. While prototype it I will the final will run from the laptop I got the screen from. It should plenty of power for a single board computer like the new pi 3 to be added and the audio amp15.4 4 wire overlay conversion many sorce's about 50$ link https://www.ebay.com/itm/15-4inch-4-Wire-Film-to-F... $Ar1100 touch to usb mouse adafuit 10$ link https://www.adafruit.com/product/1580Hdmi wireless receiver. 20 to 40$ depending on features like if it has chromecasting and such I just need video so I think the 20$ unit will do nice. These can be found in many places, so I would think this to be open end item depending on features the builder wants. I would buy the best you can afford to leave it fexible .The last thing I need to make work would be usb transmitter to make the ar1100 bluetooth or matched pair of 2.4 dongles usb this is the only item missing. I could test the whole set up but would have run 1 usb cable, but that's a deal breaker for full wireless... If I had a old bluetooth mouse and knew how take its transmitter out, that work but a bluetooth usb adapter the would plug in the ar1100 board would be the thing I need.If someone would know how to remove the mouse transmitter and wire it to male usb plug I would be happy to buy it. I real want this to made from as much recycled parts as possible.I just don't want to have run a usb cable from ar1100 to the pc.I don't think the same usb dongle that's used to the pc is the same as the one used in every bluetooth mouse or keyboard. That's my idea for a wireless touchscreen handheld All the parts are easy to get I just need make the ar1100 usb board and wireless usb transmitter. The pc would use GA-h77n-wifi mini itx as it has both bluetooth & wireless display and wifi.Part 2The idea sound lol! I want to build a frame for the screen with speakers and laptop battery and used the power supply from the Dell laptop I got the screen from, that would need a small amp. Since the receiver is hdmi, I would think the audio would be there if not that would be simple to just use a bluetooth stereo headphones and run the earphone wires to the small audio amp.I would like any comments on this idea and a sorce the one part that missing the usb mouse transmitter for the ar1100 and this could be built.So What do you folks think? A portable monitor 100% wireless that could even double as touchscreen remote! I even thought down the road to add the new pi 3 to it as that would completely independent as low power tablet or connect to the pc that nvidia gpu and could stream pc games to My Nvidia shield too. With all the power of I7 2700k oc to 4.2ghz.The possibilities here are endless you and all kinds a features adding a mic and Webcam for video calls with sckype or google voice and messenger and bingo u have a voice and video over IPThis do able you think?All comments good or bad give to me straight.Oh but go easy on the grammar thing. I technology geek but a 56 year old high school drop out. But hay at 37 I was disabled with fractured spine by time I was 40 I did all computers repairs for my local high school and was building white box computers out of my home office. If there is 1 thing I have learned in this life anything is possible but you have to try!Please be positive and constructive with your questions and comments.

Potential $5 RC Hovercraft

Hey y'all, I was bored, so I made this RC hovercraft, kinda like a Tiny Whoov, from the guts of a $5 RC helicopter (sold at most FiveBelows). The idea is that a hovercraft is more fun than a cruddy helicopter, in addition to being a fun and easy DIY project for the weekend. It could be a nice gift to a kid. My first concern was that the motors would not provide enough power to get the thing moving. They give more than enough power, and this thing can MOVE. My second concern is that the differential thrust steering system (one motor turns faster than the other, steering the hovercraft) would not be effective enough. This is still a problem that I don't have the enthusiasm or time to solve anymore. Maybe someone could figure out how to reprogram the FC board to have more differential thrust (is that possible?), or somehow configure a servo or actuator without raising the cost of materials too much. Anyway, here's the concept, go have fun with it.Supplies:Foam platesHot glue$5 RC helicopter with 2 motors and receiver (LED optional, but really cool)Connector (the battery might be soldered directly to the FC board, so this will make it easier to fiddle with)Soldering iron (not %100 necessary, but it can come in handy)Propellers (see design notes)Design notes:Notice how the underside of the hull is curved and smooth. I used propellers from a Blade Inductrix FPV Pro, but any micro quad propellers should work. Notice the nice little compartment under the FC board where you can stick a battery without the need for Velcro or glue. This would be a very easy FPV mod, but that would add about $20 to the cost.

Putting an end to flickering LED's on mains

Greetings everyone! It's the time of year when colorful twinkling lights adorning nearly every structure you can see. LED's have become more popular as of late, and from an energy standpoint that's good. I know most people can't see a 60Hz flicker but I can, and it's quite unpleasant to sit across from a tree full of LED's all doing the same on-off-on-off nonsense.  I am fortunate to only get headaches though, other epileptics I've known have actually had AC LED's trigger seizures. So what can be done about this? We bought LED strings before thinking about flicker and have since replaced them with incandescent ones, but I've still got all the LED strings in the closet. I'd really like to be able to use them.  Perhaps I could fashion a device that acted as a middleman between the outlet and the plug on the lights that would smooth the incoming current? I have two ideas for this:  1.  Filter incoming current with an RC circuit 2.  Rectify the mains voltage I'm curious if anyone else has attempted, solved, or even just noticed this frequency problem? I don't mind re-inventing the wheel, but I'd rather not build it square. Happy holidays! **yes, I just said happy holidays. Deal with it. :)

Pro vs. premium membership?

I just learned that Instructables are giving classes. It's free for premium. I know I'm pro. But am I premium member? Are they two different things or the same? Also the class is $29.95, usually consists of a series of lessons, is $29.95 for one of a series of lessons or for all of them? Thanks if anybody can help me.

Major Work Location/position sensor for a cricket bat

My name is NicholasI am in Year 12 at Parkes Christian School and making a major work that i can track where i am hitting a cricket ball on a bat. similar to what hot spot is and to be able to relay the information on the position to a phone via Bluetooth(video to help with what my idea is) At the moment i have ordered a Raspberry pi for the help transmit the data, EeonTex Pressure Sensing Fabric, EeonTex Conductive Fabric. But i dont know what else i would need so i can get the information of the position to a raspberry pi like what types of thread do i or is there some thing else i need as this is my first time making something like this Thanks in advanced

What instructables does for me.

Just a quick word to say Thanks to everyone who contribute to this site.I work as a teacher in a max-sec prison and I have to produce a lot of my classes with a very limited acces to the web. Luckily, I can acces this page.Instructables has given me a lot ideas and explanations that I have been able to use in my work - and that is all down to the people taking their time to make pictures and produce text to explain stuff to the rest of us.Thanks for that!Ramsing

More Images not showing in edited instructable on Chrome

I have edited an existing instructable https://www.instructables.com/id/Arduino-Controlle...and have uploaded extra images to step 7. The first 3 images show OK and there is an icon labeled "8 more images"when I click on it the wait symbol appears and the images never load.This seems to be a problem on my Chrome browser.Other browsers show the images but won't display them in the slideshow. The only one that seems to work on all parts is MS Edge.If you go to step 5 which has existing images and click on the icon for 6 more images they all load.
