Is this a CC Licensing violation?

I came across a blog that shared my DIY rotary tool project which is under CC-BY-NC-SA.  I am new to this licensing thing, but how the project has been shared by the blog doesn't feel right to me.  The blog admin has downloaded the images and stl files from my instructable and uploaded directly to their website and in the 'parts required' list they have put affiliate links. Does it violate the Non-Commercial license?  At the end of the article, they have a small link to my instructable.  Is this legal to do so and within the limits of the Creative Common license? If yes, What can I do in the future so that other people are not using my projects for making easy money? Thanks.

adobe illustrator cc 2015? Answered

I was drawing my .ai image during some hours and I got an error: Can’t open the illustration. The illustration contains an illegal operand. I opened it in another version of Adobe Illustrator, but it didn't aid. I suppose my adobe illustrator file corrupt. Any variants, please...

How many CC should a Moped have?

I am currently working on building a Moped id like to post as an instructable if i manage to finish it. I am currently trying to find an engine for it. The only problem i am having is selecting the correct power. In my state, the legal limit is 2 horsepower 50 cc. However, I am 150 pounds and Id like a little more info on how to choose the correct cc. I dont know what someone my weight would need for power. The speed limit on mopeds here is 30 mph. Thank you for any help!

Best Way of Boosting 7.4VDC to 12VDC? Answered

I need to power two stepper motors off of 7.4VDC, and am trying to figure out the best, most cost efficient way.  What type of DC booster circuit would be best for this application? Do I need any noise filter? If yes, what kind? If I understand correctly, Stepper motors need a constant current. Does this limit my selection of DC boosters/step up devices?

33cc Gas GS Moon Scooter Help? Answered

Ok, I already posted a question about this. The problem was a mislabeled sticker. Now I have more problems. The problem this time is my dad just randomly came out and started adjusting the idle screws for high speed and idling. It will now not run.

Help with Arduino-Midi CC out? Answered

I've never done a project with Arduino and midi-out yet, but I have an idea: I have to volume and tone pots (potentiometers) that I don't use, and are disconnected. I also use the amp simulation software Guitar Rig 4, which allows midi mapping to various parameters. What I'd like to do is this: Wire up the two knobs to the Arduino, and have them send out 2 different midi cc messages just like a control knob on a midi controller, so I can map them to different things with midi learn. The midi out can either be an actual midi out, or if possible output the messages through the usb cable. I'd like to make an instructable of this too, and all credit would be given to any help I've received. Help?

Enforceability of CC "Non-Commercial" license?

Update: I was able to resolve this issue with Jameco and I now earn a commission on the kit sales. Original post below. -------------------- I'm not sure if this is the right forum to post this, and I realize most responses will probably start with "I am not a lawyer, but...", but I figured it's worth asking. I publish all my Instructables under the CC Attribution-NonCommercial-ShareAlike license: http://creativecommons.org/licenses/by-nc-sa/2.5/ http://creativecommons.org/licenses/by-nc-sa/2.5/legalcode What I had in mind was that I didn't want people trying to sell the content - putting my Instructables in a book and selling it, or behind a pay wall on the internet or whatever (I realize the odds of that happening are probably slim). I figured the odds of anyone actually selling a product based on one of my Instructables were vanishingly small. However, it turns out that my most popular Instructable: https://www.instructables.com/id/Arduino-controlled-RGB-LED-Infinity-Mirror/ is now the basis for an Infinity Mirror kit sold by Jameco Electronics: http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_2215380_-1 It looks like this was a project by one of their summer interns, who did a "step-by-step guide" (which DOES link to my Instructable as the original source) here: http://www.jameco.com/Jameco/workshop/JamecoBuilds/infinity-mirror.html To complicate things a bit, Jameco as a feature called "Club Jameco" where you can design electronics projects (similar to Instructables) with a set bill of materials, and if it's popular enough they will sell it as a kit and give you a comission: http://clubjameco.com/ I contacted Jameco to let them know that technically I'd published the project under a non-commercial license, so they probably shouldn't have done that without consulting with me (in a very cordial manner, not threatening to sue or anything). Their response was that they thought the intern's work was "different" enough and that she put enough of her own work into the project that it constituted a different product, which I strongly disagree with (the only circuit diagram in her written directions is from my Instructable - all she really did was create a BOM using Jameco parts instead of SparkFun). I would have liked to make this my own Club Jameco project so I could earn commission, but they said they wouldn't want to sell duplicate kits like that. Realistically, I doubt I'm missing out on huge amounts of cash here (the kits retail for $80 and commission is 10% or so), so I'm in no hurry to go hire a lawyer. I'm just curious about the enforceability of Creative Commons licenses in general. Do I have the right to just tell them "Hey, you actually can't do that, because the license says so?" In theory, would I actually need to hire a lawyer and send them some sort of scary-looking cease-and-desist letter? So again, I know most Instructables users probably can't give actual legal advice...just curious if anyone else has had a similar experience. I'm sure content gets ripped off without attribution quite a bit, violating the "Attribution" and "Share-Alike" clauses of the CC license.

October DODOCase Build Night at CC Makerspace

This week at the Chesterfield County Makerspace, we were lucky enough to host a DODO Case Instructables build night.  During the week beforehand, Doc and I sat around and brainstormed some ideas for case modifications that would help make the cases better.  We determined that a head strap is mandatory to enjoy any virtual reality games that require a controller. At the RVA Makerfest, we learned that we need a way to be able to clean the faceplate from the hundreds of people that we cycled through our DODOcase, so I designed the front faceplate to be 3D  printed.  In addition to 3D printing the faceplate, I also designed a nosepiece.  I found out, from hard experience, that the cardboard is very uncomfortable for wearing any longer than five minutes; we have access to ninjaflex filament here, so I knew a fix would be fairly easy.  Here are the separate instructables for our mods: Faceplate Nosepad Headstrap Over the course of the night we led two separate groups of kids in constructing their own cases.  We printed out enough nosepieces that everyone could use one, and had enough elastic strap for people to be able to had head straps to their goggles.  Once everybody got their goggles assembled, hilarity ensued as some of the kids almost walked into walls while enjoying their virtual environments.  A few problems we noticed:  not a lot of VR apps for apple devices, some devices do not cooperate with the magnetic switch (although the DODOCase V 1.2 fixes this), and some devices were too small even for the braces to hold them in.  However, everyone had a good time and we cannot wait for our next build session.  Thank you Instructables for allowing us to put on this event.

Help with 33cc Gas Scooter? Answered

I have a 33cc gas scooter (sounds nerdy, I know), on the side I can make out what looks like Moto Rebel but not sure. It was used twice, sat in garage for one year without gas in the tank, then sold to me for $20 (Amazing price for something that's $350 new). Like new! It is 2-stroke but am unsure of the model number. It starts runs on choke between a small margin but won't run on ON, which is above choke on the switch. I think it may need the idle screws adjusted but am unsure. Has new and correct gas oil mix in tank and has primer button. Help would be appreciated.

Constant voltage AND constant current? Answered

Hi, smart people of the internet :) Is there a power supply or a converter that can be set on a specific voltage and current, and keep both constant at the same time? I looked at ebay converters like B3606, DPS5015, BST400 and the like. They all have constant voltage (CV) and constant current (CC) settings, but they can't do both at the same time. If for example the current being drawn is too high, the unit switches from CV to CC and drops the voltage as much as needed to keep the current constant. Is a simultaneous CC CV power supply even a thing? Thanks!

Solar panel short reads 28v? yet charge controller reads 14v? Batteries?

I have a solar panel that I picked up on internet for free due to damaged glass(no biggie).  Placing a voltmeter across the output leads has 28.6volts.  I connected this to a PWM charge controller recycled from a junk yard.  I set the CC parameters to 24v and hooked up two 12v car batteries(13.2v good) in series to make my 24v circuit.  Now the CC digital panel reads 14v.  Checked all the connections and retested the panel, two batteries and CC. It checks out ok. But why does the CC readout at 14v in full sunlight? yet the panel reads 28.6v? The only thing is the two batteries are different in AH ratings. One is 96 Ah and the other 115Ah.

GY6 50 cc chinese scooter won't start. What could it be? Answered

Hi. I bought a 50 cc scooter that was sitting for some time. It's 2008 model and it had around 400 km when I got it. That's pretty low in my opinion. Well at first it was running fine. I mad around 100 km on the first day. Well the second day it didn't start. Thankfully my friend helped me and he said that my carburetor is dirty. He celaned it and scooter started up. I made around 60km on the same day with no problem. In the morning the next day my scooter wouldn't start. I tried to do the same as him. I cleaned carburetor and fuel filter but scooter still wouldn't start. It doesn't start electrically or kick start. It's like 5th day and my scooter still won't start. What happens when i turn it on:  - sometimes it sounds just like a dc motor spinning but nothing happens (there is no cranking sound)  - usually it makes cranking sounds but doesn't start  - when I let it sit for a while (for 30min, 1h, day ...) it makes a sound like it almost started up but then dies Thank you all for help!

How to prevent transistor saturation?

I am trying to create my own audio amplifier. My problem was when i have large signal amplification the transistors becomes saturated, as a result the resulting signal is already clipped. This problem usually occurs when i use a transistor at CE configuration. Using CC configuration prevents this saturation problem but it also makes amplification very hard. When i use CC configuration one of the two transistors becomes "useless" because collector current becomes very low and based on further analysis it seems like only the last transistor is doing the job.

Green Roofs Capture Carbon

"Recently, Royal Dutch Shell PLC received $865 million from the Canadian government for a carbon capture and storage (CCS) project. Green roofs, rooftops with plants, can capture and store carbon, according to a new study by Michigan State University in East Lansing. The technology to build green roofs already exists, and they can be created for much cheaper than a CCS project."The key to fighting global warming is capturing carbon from the atmosphere and storing it in new reservoirs that weren't storing carbon before," lead researcher Kristin Getter said...."This looked like a rather elegant answer to the Green Question.
