While making your own PCBs at home is one of the best marks of a competent builder, if you want to give your project a more professional vibe, you’re going to need to do better than bare copper traces on a piece of fiberglass. To help out his fellow makers, [Chris] sent in his Instructable [...]

  This year at Toorcamp, [Rich] will be showing off his laser-based vector display, capable of projecting tweets using only a laser pointer, a pair of mirrors, speakers, and an Arduino. Steady hand and curses from lack of an optical bench not included.   [Rich]‘s Instructable goes over the finer points of the build; a Python [...]

[mobile_earth_explorer] sent in an Instructable he put together documenting an Android-controlled rotating monitor stand he built. The stand itself is three disks turned on a lathe out of a 18mm thick board. After turning these disks, [mobile_earth_explorer] hopped over to his bench grinder and made a semicircular tool to carve out the track for the ball [...]

The folks over at Gadget Gangster put up an Instructable to build a retro 80s 8-bit microcomputer. Even though they’re using modern components, it still hearkens back to a time when 10 year olds learned 6502 assembly, PEEKing and POKEing was the best way to program, and using a mouse was a novelty. The build uses a Parallax [...]

Sure, we see hexapods all the time at [HAD], but moving around with four legs can be more tricky kinematics-wise. This Instructable shows you how to make one out of balsa wood. Although one might not think of balsa to make their robot out of [vexedpheonix] explains that this was chosen because it’s extremely light [...]

Very rarely do we see an Instructable so complete, and so informative, that it’s a paragon of tutorials that all Instructables should aspire to. [8 Bit Spaghetti]‘s How to Build an 8-bit computer is one of those tutorials. [8 Bit Spaghetti]‘s build began on his blog. He originally planned to build a 4-bit computer but decided a [...]

[CarryTheWhat] put up an Instructable on his endeavours in printing circuit boards for solder free electronics. He managed to print a flashlight where the only non-printed parts are a pair of batteries and a couple of LEDs. The circuit is a weird mix of point to point and Manhattan style circuit construction; after modeling a printed plastic plate, [CarryTheWhat] added [...]

Whether you’d like to do some real-time logging of data, or just want to control a project with your Android phone, [Thomas]‘s Arduino-Android Bluetooth connection instructable is sure to be useful [Thomas]‘ build uses the very inexpensive JY-MCU Bluetooth module that’s available on eBay or dealextreme. This Bluetooth module ties directly into the Tx and Rx [...]

Tesla Coils are always a blast to see and are relativity simple to build. While there are plenty of sites on the subject, [Michael's] newest instructable breaks building a solid state Tesla Coil down to 12 easy steps. Items that should be familiar to anyone who has even looked at a Tesla Coil include PVC [...]

Like all of us, [Ryan] is tired of waiting for board production houses. To reduce some of that turnaround time, he modded an Epson inkjet into a PCB printer. The Instructable of his build is extremely thorough and it looks like he’s getting some quality boards out of his project The build started off by [...]

[Brian] from Louisville’s LVL1 hackerspace sent in this laser cut gear clock that’s almost unlike any other clock we’ve seen before. [Brian] also put up a wonderful Instructable for his build. Since LVL1 got a better laser cutter a lot of neat projects have been piling up. [Brian] based his clock around two cheap stepper [...]

[shadeydave] wanted to build his own Lawnbot, but he had no idea where to start. He purchased some DIY plans online which looked like they would get the job done, but then he strayed from the path in a big way and spent gobs of money in the process. In his Instructable writeup, he details [...]

This electric turtle bot instructable describes a fairly simple turtle-style robot meant to be laser cut out of acrylic (although other materials such as aluminum, MDF, or polycarbonate should work just as well). This frame is also optionally for sale, which should appeal to those that would like a mechanical robotics platform to play with, [...]

[Arthur Benemann] started a little project for his electrical engineering program, and suffered the worst case of feature creep we’ve ever seen. He just posted an instructable of his picChess project that is able to play chess on a VGA monitor with a keyboard, with sound, a clock, temperature sensor. Apparently, [Arthur] was bored one [...]

[Pritika] is a user experience design student who just finished up an autonomous blimp project designed to react to voices and communicate, “his friendliness and eagerness to be noticed.” The instructable [Pritika] posted goes through the build – a 850mAh LiPo battery powers an Arduino Pro Mini, which controls two 3.6 gram servos. While not [...]

With all the talk of radiation in the media today [freddysam] posted a quick Instructable about using standard camera film as a radiation dosimeter. Film is sensitive to other forms of radiation other than visible light, and high speed films are even more susceptible due to their chemistry, which has caused all sorts of headaches [...]

[hpstoutharrow's] new instructable is a neat idea on how to re-use those single use small propane bottles by turning it into an insulated canteen. Once the bottles are emptied through normal use, the safety valve is popped loose and allowed to vent. There are also comments on the article that suggest that the bottle be [...]

[Ken] sent us his Instructable in which he used radio telemetry to monitor the status of his air-powered model rocket through a series of launches. His setup is centered around an Arduino IDE-compatible board that looks to be about the size of a Boarduino, but has the benefit of an embedded 915 MHz radio module. [...]

[societyofrobots] recently posted an Instructable on how to build a voice controlled robot in just a few hours time. This robot isn’t particularly cheap, weighing in at about $230, but it is a fun project if you have the means. The bot is driven around by a pair of servos, taking their directions from an [...]

[robomaniac] shows us some serious application of modern technology with his recent Instructable, (the) Arduino-Fart-O-Meter. The wireless device uses a “perfboard Arduino” to read a remote wired methane sensor, and send data over a nRF2401A radio transceiver. “The data” is picked up by another Arduino / transceiver combo, which then drives a servo motor connected [...]

[Osgeld] takes on the classic VCR head jog wheel in this instructable. He has done a fantastic job not only in his build quality, but in the quality of the writeup. As he points out, the idea of using the head as a jog wheel isn’t new. His construction and build quality however have yielded [...]

[Scott] over at curiousinventor.com has posted an instructable detailing how to use an Arduino and a power drill to spool solder. The Arduino senses the speed that the drill is going via an opto interrupter and a laser and adjusts with a servo hooked to the trigger. While we don’t think many people will be [...]

[Torx] wrote this instructable on how to convert a lawnmower to another useful tool.  We’re not sure what language he natively speaks, but we doubt it is english, so you might be better off just looking at the pictures to figure out what he’s doing.  To summarize, he has lowered the mower and reversed/bent the [...]

[Banfield Design] has put together this instructable on how to upgrade or re build a head mounted display to be more immersive and add features.  Though you can already buy glasses style viewers for your media devices, they can use some upgrades. For one, you have to supply your own sound, and putting headphones on, [...]
