It seems like lately we have only been getting 4 instructables a day. is it just me or have we ran out of projects?

Hi all! I am currently designing a simple electronic device which uses Arduino-software. It needs to be connected to a car (Lead-Acid) battery of 12V and be stepped down to 5V for my ATmega328 to be powered. I read that I must use a "Standard 7805 5V regulator" for this. My question is, will it be able to cope with the heat? Must I put a heat-sink on it and/or is the regulator even "big" enough for this? I figured that using two regulators in parallel, might halve the current and help prevent over-heating. (http://www.sparkfun.com/products/107) Another thing is, how could I go ahead and setup a small NiMH battery charger for this device which works like this: It runs of the car battery at all times and keeps the backup NiMH battery fully charged - as soon as the car battery gets disconnected, it switches over to the NiMH cells. (I will be using 4 of these for my backup-battery-pack http://www.sparkfun.com/products/335) See my attached schematic of what I have in mind, please tell me what you think about it. I have too little knowledge of electronics to solve this problem myself, but if you can point me in the right direction at least, I will try and figure it out from there. Thank you for your time!

Massive walls of colorful dominoes take a tumble in this video. The most amazing thing of it all is that the creator plopped his cat right in the middle of it before knocking it down. That's nuts. My cat would've destroyed it as fast as possible. via Neatorama

The new drop-down menu, pretty though it is, does not work fully on touch screens (Android tablet and phone). The main menu works fine, but the sub-menu that pops out from shortcuts (circled in image) does not stay visible long enough to actually use - it disappears in a fraction of a second. Not a debilitating bug, but mildly annoying.

Hi I have a simple question for one of you guys but it is difficult one for me since I'm not exactly into electronics. I want to build an apparatus into my car to move a small monitor up and down - in principal like a DVD drive in a computer that opens (when the ignition is turned on) and close (when ignition is turned off). What do I need to do that?? Stepper motor - Servo motor- do I need a controller ? Or can I do this with relays ? Anything helpful -ideas- let me know.

Hello! A couple months ago, I posted an Instructable on how to build an electric ukulele and I entered it in a contest. everything was going great until recently. Now, whenever I click to view my instructable, I get an error message saying instructables is down. The weird thing is, I only get this error message when I click on that particular instructable; i can still view my other instructables as well as other people's instructables. Has anyone ever had this happen to them? Thanks in advance for any help. I really appreciate it!

I saw this article in the paper the other day and it really ticked me off. it seems we've worked so hard to battle discrimination that now we discriminate only against atheists and white people.why is it that every religion in the world is safe from discrimination by law but if your an atheist you fair game? you can wear a turban instead of a hard hat at work, you can't wear a hat in school....unless your jewish or Muslim...... if its in your religion to wear a certain kinda pants or skirt...you get your uniform altered....... but you were shorts instead of pants when its 100 degrees out you get written up.you can openly wear religious apparel or pray in public places but if I wear a T-shirt that says I pray to the temple of labatt blue I get kicked out of the mall?we strive for equality, my question is how unequal in the opposite direction does it have to get before everyone ELSE is happy?

This tutorial over on design*sponge shows you how to make some upside down planters for cheap, using supplies from around the house. I've seen some conflicting reports (mostly negative) about hanging plants upside down, but for such an easy and low-cost project it's certainly worth an experiment. Has anyone tried upside-down gardening? If so, how did it go? diy project: recycled upside down planters

While at MIT, we used to mercilessly mock my friend Sawyer because he would always start a problem set, and then lie down on the couch to think about it. Turns out, he might have been on to something. Although it didn't help that he often had a pillow over his head...http://www.braingle.com/mind/83/horizontally-smarter.htmlA recent study by the Australian National University tested peoples' problem solving abilities while standing up and lying down. They found that people were slightly better at solving problems while in a horizontal position.This difference in cognitive ability may come from the varied release of a neurotransmitter called noradrenaline, which is believed to interfere with creative thinking. When you are lying down, your body releases less noradrenaline.So, if you need to do some serious thinking, lying down may slightly boost your performance.

Hello all, I was browsing, but not limited by, the food instructables and saw that all the measurements were in non-metric values. How would it be if European members can convert cups for milliliters, for example. It would certainly not be difficult to do, but takes some time to get it all working. I know the theory of jQuery but never tried it, so thats why Im saying it. It would help so incredibly much/.

Hey guys, first forum post. I have just gotten into the electronics field, and I have made a few circuits that I have read schematics from. There's something I want to make, and it's a countdown timer. This is want I want it to have: Be able to count down from at least 15 seconds and be able to change the amount of time Have some 7 segment displays Use the least amount of voltage possible (ie: not need to use the mains or some 12 volt power supply, id rather use a couple of AA's) Have a relay capable of turning on or off a light. And to be as simple as possible. Because I am rather new to this I would rather a schematic, rather than just some help on which components I need to use, because I don't know where they need to solder to where. Thanks

I had an idea about making going downstairs fun. You grab two handles, which are connected to a frame on the ceiling. As you move/fly downstairs, the handles scroll along the frame quickly, thus making the simple process of going downstairs fun. :) Absurd or do-able? Does anyone know how to make such a thing?

Hey guys, i was wondering if perhaps someone has a similar drive like mine.For some reason, on my ibook, when plugged into firewire, it powers down automatically after 5 or so minutes of not being used, that's good. But I just cleared it off and formatted it for NTFS and put it on my server, via firewire aswell, and while data transfer and everything seems to be fine, the hard drive does not spin down, ever. And when I feel it, I can feel the heads clicking, when there's no program accessing it on my server that I can see. Perhaps it doesn't get the chance to spin down..Either way, I'm concerned about the heat it makes, and mostly, about it's longevity. Does anyone have a solution?? Is there some patch for xp that makes external drives power down??

When I touch the "you" button I get a drop down menu that does not work. example. I click "you" then "you profile" it takes me to tech shop. (the button on tech shop works) If I click "you" then click "inbox" it activates the search box underneath the drop down menu... Anything on that drop down menu does not work... it just makes the menu dis-appear and touches whatever is under the drop down...

I know they many people who visit this site also visit brassgoggles.co.uk and the accompanying forum, and i know there's quite a lot of overlap between these two sites, with members migrating here, to show off their work, for example; Heresyoftruth and aintmicheal. For the past few days, i've not been able to access the site, nor its forum from any of the computers i've tried with. All i get is a screen that tells me: "Error establishing a database connection This either means that the username and password information in your wp-config.php file is incorrect or we can't contact the database server at 18.104.22.168. This could mean your host's database server is down." Does anyone have any idea what's going on? Has anyone heard from a moderator, or do they know where i can contact a mod? I'm starting to get worried about this.

Since a few days ago many Team Fortress 2 Players have been experiencing a frustrating anomaly. Team Fortress 2 (and on occasion other source games) DO NOT WORK! This is very frustrating, opinions have been voiced that it is due to extreme server overload due to all the F2P people coming in by the thousands. This is not only frustrating but also unfair, ask one of my very good friends who actually pre-ordered Team Fortress 2, was a dedicated Gamer and Beta Tester but has now been demoted so much he can't even boot up the game anymore, while several F2P "gamers" had no trouble at all booting the game up. Does anyone else see a problem with this?

Hello ladies and gentlemen. Im looking into buying a laptop powerbank charger for my Lenovo X1 carbon that charges at 20v 4.5A 90w fast charge with upto 80% charge in 1hr. But it will also charge at 65w and maybe 45w I've read. But this will not give me the full power of the processors and gpu etc. Unless I charge at 90w 4.53A there are are some powerbank that are around £100-170 for sale but these don't give full 4.5A. Mainly around 2-3.5A so will maybe or maybe not charge she give me full power of the laptop so I'm thinking about making me own using 18650 batteries. Good Samsung or LG 2500maH plus cells. Prob around 3000mah. Im thinking I could either use a buck down or step up and use the batteries on series from 3S to 8S and then 3-4P to give me around 10000mah. I'm looking for the best efficient output so I'm not sure whether to use higher input or lower input to give me 20v. Or or maybe I could go the inveter route using a 12-24v 150w inverter?? Efficiency is the main thing here. What is the best option do you think. Should I use 12v or 24v for max effecient conversion. Ive searched the instructables for such devices but cannot seem to find anything like this. Or would I be better to buy one??? I would want to add USB and USB c also. Defo USB 2.0. Could you you please help me choose and find the answers please? I fancy the DIY route because I'm looking into solar and battery power storage and also boost my range wifi range through either ptp or directional attenna. These projects will come after the laptop powerbank. Any my help would be appreciated a lot. Kind regards. Scott.

Hey Everyone- I have been researching on ways to send out an electric signal to trip a relay to shut off my battery charger. I did find some simple circuits and I did the math for what I would need and could not find big enough zener diodes and resistors. Battery+(Resistor)(Zener Diode)(Relay Input)(Battery-) I need this circuit to send a 8.2 or 10Volt 15mA signal to my Relay when the batteries reach 235 volts. Following are the SPECS for the Input signal on my Relay::: Control Voltage Range 3-32 Vdc 90-280 Vrms (60Hz) 18-36 Vrms/Vdc Max. Reverse Voltage -32 Vdc - - - - - - Max. Turn-On Voltage 3.0 Vdc 90 Vrms 18 Vrms/Vdc Min. Turn-Off Voltage 1.0 Vdc 10 Vrms 4.0 Vrms/Vdc Nominal Input Impedance 1500 Ohms 60K Ohms 9.0K Ohms Typical Input Current 3.4mA @ 5 Vdc, 20mA @ 28Vdc 2mA @ 120 Vrms, 4mA @ 240 Vrms 3mA @ 24 V Any help on this would be great Thanks!

I just noticed that the "Shortcuts" pseudo-tab in the upper right corner no longer functions. It used to generate a pop-down menu, but now it's just a link to the page where you configure what you want the pop-down menu to contain.

For several weeks Instructables in the email won't open PDF or down load. So far the web site still works. Now it is also displaying a message "Off Line/Down" intermittently. Is Instructables down/crashed? Are the messages real or have you been hacked?

I was wondering about the kickback from a gun, i know that fired normally a gun kicks up but i thought what if you hold it upside down? will it kick upwards like usual or will it kick towards the ground? Thanks in advance for your answers. O and is the effect the same with handguns and pistols?

I am making a miniature carousel for a decoration on my bookshelf. I like to make a kind where the horses go up and down. I got a motorized lazy susan (which already goes around with it´s built in motor) so the basic rotation is there already. What I just need to figure out is how to get the horses go up and down for couple of inches. What electronics should I use for the up and down movement? I´d prefer to use batteries for the source of electricity for these. I was checking solenoid c:s on a electronics website but had hard time finding a slow ones that would work and/or don´t know how to slow them down. Thx!

Whenever I go to my You page, I get the "Instructables is down, watch this video, at least it's not velociraptors" page. This only happens on my You page, all other pages (including editing) are working fine). Happened last night using FireFox, and right now using IE.
