"We're sorry, we couldn't find that one!"

From the past 2-3 months, whenever I click on my profile, my inbox, my instructables, or any other options in the 'you' section, the message- "We're sorry, we couldn't find that one!" in red is displayed on the top of the screen. I'm unable to read the messages and to view my instructables I have to search them. I don't know is this a bug or what, but this has become very annoying. Also I can't manage my premium membership. Is this a problem with me only? Or or other have encountered the same bug as well. Anyone with solutions or any information about this bug, please comment below. Thanks.

Batch Beeps

Some kids at my school have created some sort of command prompt to where it plays beeps at different pitches to create almost what one would call music. I was quite amazed by this and was wondering if anyone else knew how to make these sounds? All I know is that command prompt is involved. Thanks :)

Help picking DC on/off switches

I'm in the process of trying to build a battery powered trailer mounted speaker system and i've got nearly all the parts now except for power switches. 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?

GoPro Scuba Cylinder Mount

Hi there, I'm new here. I've recently found an entry-level 3D online modelling software, Tinkercad and have been Tinkering ever since. I'm into scuba diving and I've long wanted to design a GoPro mount for the cylinder to give a 3rd person view of me while I'm swimming about enjoying life underwater. (Think a less-sexy Lara Croft!) I wanted to run it past you guys to see what you think. I've attached 2 screenshots, because as you can see, the mount I've designed is collapsible, to save space in my GoPro bag. I've done the maths (Pythag) so each side is perfectly lengthed to create a right-angled triangle, with the hypotaneuse (long edge) is facing down my body, towards my feet, so that the camera view won't be obstructed. I've used a Pythag triple, so the arms measure 3", 4", 5". This was done for 2 reasons: a) It was easier to desine using these measurements and b) I don't want it sticking too far up from my cylinder so that it doesn't catch on wildlife/coral/divers. As this is my first GoPro mount that I've designed, I've had to go on deimensions I've found online for the actual hinges. I've settled on approx 3mm for each prong as well as the gap in between. I have actually shaved off .25mm from the middle prong of the 3-pronged-hinge, and left the 2-pronged-hinge at 3mm for the gap and prongs. I'm going to get the pieces 3D-printed by a local service I've found on 3DHubs.com, either in ABS plastic or in resin, though I'll probably go for ABS as it seems to be a bit more hard-wearing, even if it's not so detailed. In terms of mounting it to the tank, I will use 2 headstraps, with the over-the-top strap removed from each one and glue the plastic bits of each of them together, at the correct length of course. I would join them using a seperate piece of plastic and either a hot glue gun, superglue or even some sort of epoxy, whatever lasts longest in prolonged exposure to seawater. I would probably place it nearer the top of the tank, near to where the strap of the BCD jacket goes round it. Does anybody have any advice for me in terms of the design from a functional point of view as well as from whether they think it would actually get a good shot on the camera please? I look forward to your feedback, good or bad!

Remote Lockbox

I would like to build a small lockbox to which I could remotely provide access.  For example, I leave the box at a property.  At a later date, an employee is in the area and we would like him to access the property without having to make a trip back to the home office to pickup the keys.  We provide him a one-time access code and he retrieves the key. I recently discovered how much fun Raspberry Pi DIY projects are and this seems like an ideal candidate for my next challenge but I have to confess I am still a total neophyte to all this with no real notion as to the best way to move forward.  I would welcome any suggestions or ideas.  I also realize my definition of the problem might be more vague than is ideal but given my lack of confidence vis-a-vis which details are relevant, I thought it would be more productive for me to answer questions rather than post a giant wall of useless information - which is my long-winded way of saying, please do not hesitate to ask me any questions if they'll help get me pointed in the right direction.

ZipDart prototyping help

OK, had an idea and went with it for my ZipDart V.2. Unfortunately, currently having a bit of a brain fart of how to put a ratchet mech in. I've tried 7 attempts, 3 have even actuated and of those three none were responsive enough to be at all deserving of the ZipDart name. There is a google photo album linked below of the mech area and the gun on a whole. Feel free to comment either there or here with any ideas or insight. The mech can be complicated, just so long as it takes less than a half an inch of actuation rod travel to actuate and is fairly strong.

As sarcastic as that may sound, I mean it in all sincerity. Criticism is a good thing to learn from, and it has made me into the person I am today. Thanks again everybody!

USB type C

Greetings, USB type c please? So I have spent alot of time researching different ways to light small ornament designs. I have considered EL lighting and LED, yet, in order for these lighting techniques to work sufficiently, you need 12v of power. There are Instructables to power these lightning methods per USB, however this ofcourse only provides the lightning with 5v. What I find quite surprising however is that there are no tutorials whatsoever with the new usb type: USB-C. Since USB-C can apparently provide 20v I wonder why there is little to no information available concerning these subjects. Are there technical limitations I dont know about? If not: would anyone please help me make usb-c powered led strips ^^

In the seven years I've been on Instructables, one thing I know to be true is that the community has changed. A lot. It is amusing to look over the "How to Steal An Instructable" post made years ago, which satirized the theft of projects. Looking back on things as old as this proves funny but also depressing though; the community has changed so dramatically in the years that have transpired that copied projects are now no longer the objects of satire or chiding but the recipients of praise and prizes. A few months ago, when I again broached the topic of copies on Instructables and the problems they cause, I was met with responses indicating that to overcome copycats all one needed to do was work a little harder. That is, those who have already put forward the effort of actually developing something new and of their own design should now work even harder to succeed. Curiously absent was any suggestion that copycats exert themselves and actually do something say--original. By chance, I ran into a thread I had not seen in years while writing this: the thread on the "Instructables laws," guiding principles users ought to observe. There are four, with some accompanying notes to all. The first entry, the Zeroth Law, is the one relevant to projects and their content. It states that: "if an Instructable exactly like yours has not already been posted, then you shall post your Instructable." An addendum is made to it, stating: "If your Instructable has an identical goal to a pre-existing Instructable, but achieves that goal by a different or improved route, or in a different style, then you shall also post your Instructable." The legitimacy of simplicity is also noted in an accompanying corollary. None of the above ideas are wrong. On the contrary, it is people ignoring this thinking which has caused serious issues. Nowadays, people know other projects have been published with identical instructions (and even superior quality), yet they proceed on and repost it themselves anyway. Furthermore, their copying usually violates the copyright restrictions laid out by the original creator. When the Instructables laws were written down, it is clear that original content was valued highly and respected. Nowadays, the dedication of the community toward these ideals is questionable to say the least. Today the community displays a disconcerting apathy toward makers and what they do. Just a few weeks ago, I was told the community is not interested in anything but the results--that the makers and their efforts are completely irrelevant. I'd rather not believe that is how the community at large believes things ought to be (especially given that it's a particularly unimpressive pitch to attract new makers and new ideas), but it seems like it may in fact be just that. With that in mind, things have obviously changed--for better or for worse is in the eyes of the beholder; I have already reached my own personal conclusion.

How to Lit a 1watt LED using a NOKIA charger

I would like to lit 1w Power LED using NOKIA Charger. Mostly, a 1watt Power LED's specification is 3v0~3v4 DC Volts and 350mA Current. Printed specification on Charger Cabinet it is for - Input 100/240v 50~60 Hz…„ Output 5.7v/800mA. For Series Resistor's Value…„ if we calculate upon Ohm's Law - for VoltageSupply, Vs 5.7v…„ ForwardVoltage, Vf 3.3v…„ ForwardCurrent, If 330mA to lit single LED. In Result we can use a Standard Value of Resistor 7.5 Ohm and because of Resistor's Power Dissipation 792 Milliwatts, can use a 1watt. In series I planted 10 Ohm 1w Resistor instead of 7.5Ω. LED lit up in normal. Neither too much nor too little shining. But…„ about two and a half hours later it was flashing. I switched it's off and checked that the charger unit also became hot. Where I made mistake…? Please HELP how to lit this 1watt LED using this NOKIA charger. I also have one another charger with printed specification on cabinet it is for - Input 100~240v 50/60Hz…„ Output 5.2v/400mA. I also want to use this for one another 1watt Power LED to lit. Please help for this too. please ignore my  bad english.

High current variable voltage from an atx psu

What would be the most simplistic way to draw up to 10a on an atx PSU using variable voltage controlled by a potentiometer? I've looked at a few diagrams using the LM317 but it is limited to 1.5a. The only other VVR I can find is the LM350 but is still limited to 3a. Any ideas? I was thinking of stacking an arrey of LM350s in parallel but this doesn't seem like a viable answer.

I'ble won't publish.

I'm not trying to complain or make an issue, just thought I'd put it out there.  I am having issues posting my latest I'ble. Everything's fine up until I hit the "Publish" button. Nothing happens, no error, my browser doesn't attempt to do anything.  I'm working from a Desktop. I tried clearing my cache, cookies, history, etc. I also tried on Chrome and FireFox.  I know you guys will get this squared away soon.  - Adam

Does anyone know how I could put a knex gun into this body? I like the p90 design,  just can't get a gun into it. Maybe a rail gun design could be made use of here. I also want the mag on top like a real p90 if you're gonna give me a design. ....if the top mag is possible
