Heres a question, I have a digital audio recorder with a builtiin microphone. I would like to either a) add a jack to plug an external microphone into, or b) replace said built-in mic with a jack. How would one go about doing this? Is it as simple as soldering in the jack? Thanks, Anorath

Hello people. I'm new to this business of building laptops, so I don't know anything, even where to get the parts. I would like to build a nice gaming laptop. My budget is 1000$, so if anyone is able to post a good set of parts including the barebone (so the parts would fit the barebone). Thanks in advance.

Over the summer, I designed and built an extremely simple single-shot .22 pistol. Below is a video showing all of the parts and the first shots fired. I did this as a design exercise and to see how hard it would be to build a reliable firearm, going from idea to 3D model to working prototype in about three weeks. So far I've fired over 200 rounds with 0 malfunctions, however some parts still need to be heat treated and I need to apply a finish and maybe add some sights. When it's completely finished, I'll port my blog posts into an instructable.

Hey, I thought if it's possible to add the electronics from a guitar pedal to the guitar itself. It would obviously take some space, but it didn't seem impossible to me. Any ideas, is this even a realistic idea? I must do some more research on how much place it would take and how to wire etc. Any help or thoughts are welcome!

Morning all from the shire or Oxford UK My names is Rory, happy to be a member of the site and always enjoy a good discussion Thought it would be helpful for myself and others to start a bit of a debate about 3D printers in general. I build my own 3D printer last year and was happy with it the 6x6x6 results were not the best but better than anything I had produced before, I regreted ever selling it TBH but now the time has come for me to think about getting another. Ideally looking to have a scanning unit too but it is wether to build or buy.......TOO MUCH CHOICE!! Since last year ive seen a massive jump in the tech used in this area and my main questions are: What do each of you use and why that specific printer? Whats your best results ( best object made ) which to people perfer shop brought (ready made) or home made (DIY KIT) If you could choose any 3D printer what would it be? Cheers all, Look forwards to seeing how this thread discusses this topic

Construction is nearing completion in Taipei of a plastic bottle building. Technically a temporary structure, "the world's lightest, movable, breathable environmental miracle" (say the designers) is also strong enough to withstand typhoons and earthquakes. The building will eventually become an exhibition space. Much is being made of the structure's "green" credentials - LED lighting, and particularly the construction material; 1,500,000 recycled PET bottles. That sounds great, and in most of the news coverage of the structure (such as the BBC and Treehugger) it sounds like the building is built directly of bottles that have been re-shaped somehow (maybe squashed in a heated mould). The bottles even have lids, and they talk about filling them with air, water or sand to change the thermal properties of the building.. It turns out, though, that the building material is not "PET bottles", but "PET bottles chopped up, melted and re-formed into much thicker-walled bottles intended solely for building", branded as Polli-Bricks. OK, still recycled, still greener than most building materials, but it smacks of spin to just say the building is built of bottles. The Polli-Bricks are impressive - individually nice to look at, and fitting together snugly "like Lego" - but there is no indication of how much energy is spent creating them. They are made by Hymini, but the Hymini website flashes up all sorts of alarms with my firewall and anti-virus as an "attack site". There is more information at Miniwiz as well, but some of the links there also trigger alarms. Maybe I'm being a wet blanket. It is a nice building, after all. What do you think? GreenMuze article

I have a design for original body armor, but I don't know where to buy it or get it built. Think of a nomex survival suit, but Dragon Skin and Kevlar for fabric covering underneath armor, 2nd layer U.S.A. brand or Japanese exoskeleton suit with titanium caseing, 3rd layer graphene and dragon skin for plates covering entire body like a full body mold but cut in pieces for flexibility. Where can I get this built or how can I build it precisely. It will last against a FN FAL. I live in McAllen Texas. I prefer professionally made, so any suggestions. I have no budget.

Hi all, I found this contraption today at the tip and was wondering if anyone knew what it might be? It has been hand-made and looks like it measures something but I can't work out what. It has a micro amperage meter, an LED, a bunch of coils which look like they are from a heater, and also a analogue clock on top with no hands. Oh and it also has some small glass tubes on top which look like micro movement switches. I thought it might be used to measure lightening or some other environmental effect. Maybe earthquakes? any ideas?

Hello everybody! I've moved most of my robotics projects to Let's Make Robots (All LMR are belong to us!) and I'm gonna do some wood-working now! I decided to build a kayak. Why? I dunno, I want to build one, and I always wanted to go kayaking. No I'm not gonna go take lessons (tips/tricks are welcome), I'll train myself. I'm expecting a couple capsizes. LOL. Anyways, I found a program that helps to design kayaks called Kayak Foundry. The software tells me where to put the sheer strip, where the waterline will be, and it also generates the forms to build from. The only problem I have is that this thing will cost $400-$450 to build. Before I invest that kind of money in a possible failure, I need to know if I have a stable design. Below are the cross sections and a model I made in Google Sketchup (gotta love free software!). Take a look at them, I need to know: -Is the design stable -Will it float with a 185lb man in it The software gave me a stability rating of 90 (out of 100, with 40-50 being a racing kayak) Also, there are pictures of data from the software. the red line on the graph is my design, the black line is the target. Also, on the volume distribution curve, the line should be right in the middle (the cockpit or whatever it is called should be in the middle of the boat.) I guess I forgot to save or something. If you can help, please do. I'd rather not spend $400-$450 dollars on an unstable boat that always capsizes. Thanks, Gimmelotsarobots

Over in Texas, a new laser has been built that can zap with a full petawatt of power. That's a quadrillion watts (that's 15 zeros) of power that gets blasted in 150 pemtoseconds.While this is not the most powerful laser ever made (that was a 1.25 petawatt laser) it is the most powerful laser currently operational. All for the cost of $7 million.So what's the point of it all?"We can put materials into states that you can't access here on earth," said Mikael Martinez, the laser project's manager. "You'd have to go out into space and hang out with an exploding star to observe what we plan to observe here in Texas."Check out the full article at Wired to see how they pull off this trick.

I'm trying to build an NAS with a spare computer I have. I'm trying to run Freenas, but every time I try to install the OS, I get a read error: 0x20 The computer in question is an old alienware M9700 my cousin gave me. For some reason, the computer doesn't give me the option to boot from a flash drive, so I assume it can't. So here are my questions: 1. What is this read error I'm getting? I've tried googling it, but I've only gotten very mixed results on it. 2. Is it possible to run Freenas this way? (without a flash drive, via disk) 3. Since the laptop has two SATA ports, could I install the OS to a smaller HDD, and then use the remaining as the storage space? I've been told that you can't install the OS onto the same drive intended for storage.

I saw a quite old "home improvement" show from the 80's the other day and was stunned to remember how much we gained in ready to use parts and tools these days.A part of the show focussed on a custom made dining table with a matching cupboard/sideboard.The interesting thing here was that no nails or screw were used.Tongue and groove systems, smart notches and such were used instead with just wood glue.I admit the professionals made it look easy to use a hand planer and chisels to carve out some ornaments and details but the result speaks for itself IMHO.We now mainly use power tools, ready to go parts like metal angles, easy screw systems and so on.Wouldn't it be great to have a contest where people actually build wooden furniture, even if it is just a chair, by using traditional tools only?To misuse the term call it "Organic furniture" ;)

I don't mean like exotic or cut pieces, but like Y joints, ball and sockets. I have like only 2 joints -.- I know you can get most of these online, but the fact is it's a hassle. So here are a couple original designs I made myself. Comments? The first is a just a front loading pistol I built mainly for looks, it's suppose to be a Desert Eagle replica.

I guess mobile phones and ipods are examples of this. So, you have a device that has a removable rechargeable battery that you can usually charge directly in the device. Sometimes, (like in laptops) you can plug in to the mains and run the device without the battery at all -- bypassing the battery, so to speak. You can't do this with phones or ipods though. If you remove the battery, the device won't run. Is there some guide/hack that would show me how I could get round this? Thanks.

Have you ever been interested in having one of those neat computers that are lighted inside, but don't want to pay for an expensive computer. Now you can get a lighting module for your PC for as little as ten dollars. I am building LED modules for users to integrate into their PCs. The standard ones have eight LEDs, run off of the standard molex power connector, and beautifully illuminate your PC. However, I can custom build an illumination module with almost any features you want I can even use blinking LEDs. And the best part is they are cheap, the standard module will only cost you 10 dollars plus shipping. These are built with quality parts and are fully tested. The standard module is built with eight high luminosity white LEDs, just like in this instructable https://www.instructables.com/id/LED-Light-Module-for-Your-PC/. I can customize these in the following ways: More or less LEDs. I can use any number of LEDs that is a multiple of four. Blinking. I can make these with all or any number of blinking LEDs. Different breadboard sizes. I can make these with any standard size breadboard If there is a different modification you want then let me know and I may very well be able to do it. Extra modifications may cost slightly more, but they are still significantly cheaper than an illuminated computer cases. Look at the pictures and if you want one or wish to inquire about shipping post or PM me.

Recently, i found a audio amplifier chip, the TDA7496 to be exact. when i found its datasheet, it included a circuit for a audio amplifier. i built that circuit, and it made my music quieter, not louder. the sound level didnt change even when my input device was at max volume. (my laptop) i tried the volume adjuster and it did work, but only to lower the volume, not raise it. i followed the circuit, the 'mute' and 'standby' switches were hardwired to the 5v points, like the circuit shows the switches being at default (off) the SGND seemed to be connected to PW_GND (tested via multimeter) internally, so i added a wire to ground externally to be careful. im using a 15v power supply, and a 5v regulator. i assumed all the down pointing white arrows were all to be connected. capacitors 2, 3, 5, 6 and 8 were not put in. i used polarized capacitors for 9 and 7. all of the capacitors are rated for 16v. i tried disconnecting the mute and standby lines, but that didnt change anything.. so ive attached the circuit in question, can someone tell me what might be wrong? i have also attached the datasheet.
