what CAD package/software do you use?

Hi - I have been using SketchUp for a couple of years, and grown reasonably proficient in its use.  However, it's not very intuitive in terms of being useful when trying to sketch ideas, find correct proportions, squeeze or stretch items until they "look right".  Having always to think in terms of creating drawings from extrusion of 2d surfaces is not often helping creativity! So, I am interested to learn and hear about anyone else's experience of using alternative CAD software in light of my comments about SketchUp - what do you use?

Take a tour of Instructables!

There's so much cool stuff here, I thought people (new and old) might enjoy a guided tour. Instructables is a web-based documentation platform where passionate people share what they do and how they do it, and learn from and collaborate with others. These awesome people make it all happen. The seeds of Instructables germinated at the MIT Media Lab as the future founders of Squid Labs built places to share their projects and help others; more history is here. Instructables is the combination of a number of things. First, there are the Instructables themselves. These are step-by-step descriptions of things people want to share. They are educational, inspirational, and often replicable. The Dachshund Wheel chair is my favorite. A passionate user shared something close to his heart, and has had a positive impact on many lives.There's the whimsical: Magnetic Acrylic Rubik's Cube. And, of course, the whimsical inspired by the whimsical: Magnetic Rubik's Dice Cube. And, the plain ridiculous: How to Get a Free Yacht and its complete saga. A cornerstone of what makes Instructables great is the comments. People ask questions, give praise, or offer improvements; this sets up a conversation between the project author and the community. Check out this cookie recipe where the author responds to a question about substitutions for someone who wants cookies now.Many of the best Instructables have won one of our contests: Show Your Heart Valentine's Day Contest, Holiday Homemade Gifts contest, Take Thanksgiving to the Next Level contest, Halloween Project contest, and The Magnet Challenge. Instructables has a lively forum for opinion and discussion. Really smart and talented people hang out here. Have a look at a forum topic on water tunnel testing complete with Reynold's number equations.Finally, what really makes Instructables great is the community surrounding it. These are passionate people that want to share what they did and how they did it. In recognition of this, Instructables won the 2006 Wired Rave Award for industrial design. Instructables gave power to the individuals so they could positively impact the world. Also, check out some of the news articles about Instructables.

The Bravery of Being Out of Range: A Technological Revolution

The 18th century gave us the beginning of the Industrial Revolution. Purpose-built factories for the new industries such as iron and textiles. New and improved methods of transportation, communication and production. It changed the way people lived / worked and it created / inspired a lot of what we still see and use today. This revolution had its negatives too. Jobs were lost to the industrial machines that did it better and faster, the poor and the working classes often had to endure grim living and working conditions. The black gold mined from underground, fuelled our thirst for advancement. Now in the 21st century, we are in the midst of the Technological Revolution. Ubers, drone deliveries, driverless cars and trucks, AI, Google, Facebook, Amazon Alexa, unmanned military vehicles, war by remote control and the bravery of being out of range. The drones, AI, robots and automation may not only take away our jobs, but potentially the need to leave the house or to have any real-world face to face interactions. They could re-define our lives, for better or for worse. Are you fearful? Wary? Or do you embrace the changes going on all around us?

Wireless FM microphone real time voice/play transmitter

Hello I am looking to buy/build a small FM wireless transmitter with built in microphone (similar to karaoke but not exactly ) to transfer voice or sound  from playing  musical instrument  to earphone. It is meant only for practice purpose so does not need  high power, the distance between the microphone (the transmitter ) to earphone  is like from mouth to ear a few centimeters say about  50 cm. I am electronic junior engineer and have knowledge and experience in electronics mechanics and wave buy. Before trying to develop a new product  I was looking for a readymade shelf product. The first way I have searched the internet and reached manufacturer of Bluetooth solutions because of the plenty of Bluetooth earphone that are on the market, but quit a short time after I got some answers from the the Techs engineers  of the manufacturers that Bluetooth will not be my solution because It was not originally designed for true real time transmitting. The main problem is the latency time because there is a delay between the voice or play start until I hear it in the earphone there is improved in Bluetooth 4.1 and 4.2 that is 38 MS and may be not enough while fast playing, So as I was advised I started looking in the RF FM area. FM transmitters are long time in the market of stages and performers, there are high power grate quality transmitters that cost hundreds of dollars. Here is the summary of what I need :        I will need the smallest device (PCB) can be like FM spy bug transmitter. built in microphone (on the PCB ) , built in battery compartment (on the PCB ),built in antenna a copper loop on the PCB (no wire) Since there may be some problems like saturation of microphone or other problems with band width or  sound and sensitivity, sensitivity and control for the Microphone is important. Easy calibration of  tuning and stability , may be digital tuning is better. One option is to use the standard of radio FM 88-108 , but it possible that I can use FM VHF or UHF system that have both transmitter and receiver . If there are no ready made products thatn I can easy build a kit , or from schematic diagrams I will be thank full if you have any ideas. Nevat Ben Haim Recomp Computers

12v solar panel/battery setup project- NOT lead/acid

Hi, I have a project that I'm trying to design/build and could use some help/advice with some of the electrical theory. I feel like this should be really simple but I'm having a lot of issues. I have done a lot of googling but can't seem to find applicable answers so I started my own thread. Any help will be greatly appreciated! If I can solve this, I will be happy to write up a detailed instructable so that others can use this information as well.  The short version: Trying to build a lightweight solar panel>battery pack>UHF radio charging setup. Nominal voltage is all 12v. I'm having difficulty regulating amperage between the units. The long version: My friend is in charge of a campsite which needs to have a 2-way radio on at all times. They need to be able to charge these radios on-premise because they are out there for a little over a week at a time. A solar panel seems ideal for this application. The whole charging setup needs to be lightweight since it is a >10 mile hike into the campsite. Ideally, I would like to use an array of NiMH AA batteries because they are small, relatively cheap, and can be replaced easily if there is an issue. I am also under the impression that they handle repetitive charge/discharge cycles well. I am not married to that though so if there is a compelling reason to use lipo or something else, I am open to that. The radio: is a Motorola Radius CP200. The wall charger that comes with it outputs 14v at 1.5 amps. The battery in the radio (according to the sticker on it) is 7.4v 16.21Wh lithium ion. Setup 1 that I've been trying: I have a 12v solar panel charging a pack of AA NiMH batteries. I started with an 8-pack holder but moved up to a 10-pack to increase voltage and total mAH a little. I've been using little voltage regulators in between the solar panel and the batteries as well as between the batteries and the radio. These function as diodes and help me get the correct charging voltage. My problem is that I can't regulate the amperage. The battery pack will pull as much as it can from the solar panel, and the radio will pull as much as it can from the battery pack. What ends up happening is when I first plug the radio into the battery pack, it works fine. But after a couple minutes, the amperage skyrockets to like 3 or 4 or more amps. The voltage regulator hits some sort of thermal protection limit and the whole thing shuts down. I tried throwing this amperage regulator in there as well to keep it below 1.5 amps, naively thinking that it would just affect the amperage and not the voltage. But what happens is when it's in constant amps mode, it just cuts the voltage to compensate and keeps the total power the same. Setup 2 that I've been trying: I thought maybe since I was having issues with the 'smarts' of these batteries charging and discharging, I would switch over to USB battery packs since they have a lot of built-in protection circuitry. I got this solar charger, an older version of this battery pack, and used the same voltage regulators to step up the voltage from 5v to 14v to charge the radio. I get the same issue of high-amperage discharging of the battery pack. I tried using this step-up converter between the battery pack and the radio but it doesn't seem to work or maybe I'm not using it correctly (I can't seem to get the adjustment pots to actually do anything...). It seems like I'm thinking about current wrong or something. Any suggestions or insight into what's wrong with my approaches would be super helpful. If anyone has any suggestions for radically changing my approach, I'm open to those as well. Thanks for reading!

Voice-cancelling earphones or headphones

Many brands compete with noise-cancelling technology, but all offerings seem tuned to mitigate frequencies other than voices.  I appreciate that on an airplane or gun range, but in an open office plan, the only common attempt at mitigating vocal pollution is to add white noise variants.  White noise systems have limited effectiveness and alleged health drawbacks.  My noise cancelling headphones cut the white noise, effectively enhancing voices that I want to shut out.  I can use "sound-isolation" instead of "noise-cancellation" but they are bulky and hot.  I'd think it would be possible to use noise-cancellation technology to target vocal frequencies.  Thoughts?

Any tips on disassembling bullet camera and relocating the lens module?

Hello!  I've been reading instructables for a while and now it's time to join and post a question. I've been finding nails in my driveway and want to catch who's doing this.  I've got a 4 channel security camera on it's way and have been thinking and researching ways to hide them.  Due to the 'clean' surfaces around my home, it's going to be tough to make the 2" diameter x 6" long bullet cameras blend in (so people don't vandalize/steal them).  I've spent hours searching how to camouflage cameras, so I know the 'typical' tricks. I'm thinking about making a fake gutter extension and hiding the camera in there (so it blends into my one story house), possible installing a gable vent on my garage and pointing a camera through that, or trying to mount a camera about 20' up a nearby tree.  My favorite idea is to take apart a bullet camera and move the camera lens module, which is much smaller than the whole camera housing, to a more discreet location. I've searched for a while but can't find anyone who has done this with an IP66 outdoor style camera.  I know I'm going to lose the IR LED's around the lens, and that's ok (I'll have 3 other cameras for night vision).  I think I can point the camera through a small knot hole in my privacy fence and be able to detect who has last walked by when the nails appear.  I might make a small weather proof enclosure to protect the lens module...I think I'm a good tinker-er so this isn't the problem. Has anyone hacked apart a security camera and moved the lens module (by extending the wires) to a remote location?  I know there are small cameras for sale, I know I can hide a camera in a bird house, etc...but I like to make things.  I'm just looking for advice/tips from someone who has done this.  When I search for 'hack apart a security camera' I get a bunch of 'hacking into a security system', or 'spy on your neighbors'...I don't want to do either of those.  I have great neighbors, I live in a corner house where a lot of people/kids walk...I just want to catch them.  Once I know who's doing it, I'll move the cameras to more visible locations (to deter others from doing anything else). Thanks for any help!

Instructable editor pastes content in the wrong place

When pasting content into the Instructables editor, the content doesn't always get inserted at the cursor's location. To reproduce:  1. Start a new Instructable, and edit the first step.  2. Enter some dummy text, followed by a newline.  3. Use the "formatting" menu to change the current format to "code".  A grey box will appear.  Place the cursor inside the box.  4. Copy some source code (from a separate editor or a separate tab) and paste it into the grey box. What should happen:  - The content on the clipboard is pasted inside of the grey box. What actually happens:  - The content on the clipboard is pasted immediately after the grey box. A partial workaround is to paste the code first, then highlight it and switch the formatting to "source".  Pasting the code when formatting as normal text causes the code to be modified, however (whitespace and newlines get mangled/combined).  Aside from being annoying, this can break code in languages where whitespace is significant (like Python).  The paste function should work as expected, and insert the pasted content as-is at the current cursor location. I am currently running Firefox v52.0.2 on Windows 7 (64-bit).

When I say Inchie, you say What?Inchie!What?Inchie!What?I just this minute found out about this whole Inchie movement thing, and I LOVE it. An Inchie is a piece of art that is 1" x 1". The end.It can be made out of anything you want. It has to be 1" squared. I'm beginning to really catch on to tiny crafts (as you may see in some upcoming I'bles), and these are too adorable to resist. My first thought is that I'd be way too impatient to work on such a small scale. My second is that I could have a complete work of art in under 30 minutes. . . So.Here are some examples I came across on Craftster. Rainbow Inchies1000 squaresPhizzy's InchiesAnd well, you get the idea.Enjoy and be sure to post your own inchies!

Foodsaver Freshsaver Handheld AC power hack

Foodsaver makes a small handheld unit called the freshsaver handheld. It is rechargeable but has a strange design which requires the unit to be pre-charged immediately before using. After use, the unit does not hold a charge very long. 24 ish hours if I recall correctly. The starnge thing is the unit will not operate when plugged in. I guess it's just designed that way. I remember seeing a tutorial on how to make this thing work on ac power but, I just can't find it now, no matter how hard I try. Would some kind soul please solve this puzzle for me and make an instructable? Pretty please?

Wind powered desktop PC, is it remotely possible?

So I was thinking up an idea this afternoon about how I could be more of a PC enthusiast, I came up with this idea: What if I could power a desktop grade PC on just the power supplied by a wind turbine (preferably that I had made myself), and batteries? My plan was to set up a (either or) BOINC Computer specifically for research, or something like a DNS/VPN server or failing that something like a NAS. Anyway, heres what I have been able to find so far in terms of wind turbines and power... It seems way over my head, especially the second link to the other question. Computer Specs that I had in mind: Intel i5 K series chip of sorts 8-16 GB of (presumably DDR3 memory) A motherboard, again, not sure exactly what but this can be chosen nearer the time, if it helps, something with around 2-4 PCI-e lanes for numerous GPUs. (This is NOT meant to be a gaming rig). A couple of GTX 760's I was having in mind, something older will do too. (This would be using the CUDA technology for accelerated processing) A Power supply that would fit the bill... 1000 watts? May be needed depending on the number of GPUs I have. I am so ignorantly unaware of how this would work.  Other things that I would need: - A wind turbine that was able to charge batteries during the day (for example) - Batteries - Some sort of converter (I think) to change whatever AC power there may be into DC. I think that is what I need,  Thanks in advance! slippers.

Looking for a plans for k'nex motorized lazy susan

Hey :) I'd like to build a small lazy susan out of K'nex. I've got a pair of the blue motors that I'd like to use with them. All my searching is coming up with nothing and I am NOT the creative type. I've tried. I know it's possible, I just cannot figure out how to do it. I want to be able to put small objects on it for display. Could someone point me to some plans? Thanks so much!

Voltage rail identification on LCD PCB

I am testing the DC rails coming off an LCD TV PSU so i can convert the unit to run off an ATX PSU. i have managed to find (labelled on the board) 12v, 12v, NC, GND, GND, GND, ?, ?  the last two aren't  labelled. the two pins (when tested to GND) are giving me -12v, could this be right? I'm guessing by this point ill just have to use the 12v rails, GND and -12v from the ATX to get this powered?  what else could those last two pins be?
