This coffee table is a real show-piece. It’s got a smoky glass surface that is hiding the LCD screen within. But what fun would it be if it could only play video? The rest of the enclosure houses all the parts necessary to make this living room centerpiece into a computer. After the break you [...]

Behold this ATtiny85 based EEPROM programmer. It seems like a roundabout way of doing things, but [Quinn Dunki] wanted to build to her specifications using tools she had on hand. What she came up with is an ATtinyISP USB programmer, pushing data to an ATtiny85, which then programs an EEPROM chip with said data. The [...]

[Quinn Dunki] has been busy through the holidays giving her 6502 processor-based computer a place to live. The most recent part of the project (which she calls Veronica) involved designing and etching a mainboard for the device. In the picture above it’s the vertical board which is right at home in the backplane [Quinn] also [...]

[Arnuschky] was looking for a network storage solution that included redundancy. He could have gone with a new NAS box, but didn’t want to shell out full price. Instead, he picked up a Dell PowerEdge 2800 and hacked it for SATA drives and quiet operation. It’s not surprising that this hardware can be had second-hand [...]

[Phil] uses both his computer’s speakers and a set of headphones while working at his desk, but he was growing tired of constantly having to remove the headset from his sound card in order to insert the speaker plug. He’s been meaning to rig something up to make it easier to switch outputs, but never [...]

[Quinn Dunki] keeps rolling with her 6502 based computer build. This time around she’s added some memory to store the programs, but needed a way to get that code into the device. Above is her solution, a bank of hex switches used to program the 8-bit command and 16-bit address for each line of machine [...]

[Hamster] wanted to take a look at division operations when the chip you’re using doesn’t have a divide instruction. He makes the point that the divide instruction takes a lot of space on the die, and that’s why it’s sometimes excluded from a chip’s instruction set. For instance, he tells us the ARM processor used [...]

For years, [Rasmus] has left his computer connected directly to the mains power so that he can turn it on via Wake on Lan. While powered down, it would still continuously consume about 6W of electricity, but now that he didn’t need it to be on standby so often, he wanted to make it more [...]

If you happen to do a lot of video encoding, you know that your computer can really drag while the process is carried out. Our own [Mike Szczys] transcodes videos at home fairly often, and because the process is automated, he doesn’t always know if a conversion is taking place in the background. He has [...]

[Richard] wanted to create a color profile for his computer monitor, but he wasn’t thrilled with the existing color calibration offerings he found for sale. Color calibration tools can be somewhat costly, but even more troubling to [Richard] was the fact that they are all closed source. Closed hardware and closed software can be a [...]

[Oliver] had an old NES controller laying around, and without any other use for it, he decided to repurpose it as a portable storage device. He gutted most of the controller, removing the plastic standoffs, leaving the D-pad and remaining buttons intact. He crammed a 32 GB flash drive inside, along with the guts from [...]

[Jeremy] had an ASUS EEE PC 1000HE netbook on his hands which had succumbed to a corrupted BIOS. In most situations, people replace a motherboard when the BIOS is damaged beyond repair, but considering the price of motherboards, especially those built for portable devices, he simply refused to go that route. Instead, he took it [...]

If you’re not willing to shell out for a reasonably powerful laptop it seems that there’s not a ton that can be done to boost your gaming performance. That is, unless you have an empty Express card slot and the right chipset. [Phatboy69] recently put together an external video card for his notebook, with fantastic [...]

[Taylor] popped a new graphics card into his computer, but before he could settle in for a round of gaming, his card started to overheat. He eventually tracked the problem down to an undersized power supply, but the prospect of cooking his new GPU to death made him think twice about how he was monitoring [...]

[Julian] picked up an old record player that was sitting in somebody’s trash pile, and brought it home to see if it could be restored to working order. When he got it home he discovered that it didn’t work at all, so he and his wife decided to modernize it a bit. In an effort [...]

The problem of persistent and reliable storage plagues us all. There are a myriad of solutions, some more expensive than others, but a dedicated and redundant network attached storage solution is hands down the best choice for all problems except natural disaster (ie: fire, flood, locusts) and physical theft. That being said, the issue of price-tag rears [...]

Instructables user [Jan] likes to keep close tabs on his computer’s memory usage, but wanted something more interesting to look at than the standard resource manager. He preferred to have an external display available that would show his computer’s status with a quick glance, and thus this system monitor was born. His status panel contains [...]

[Frank], like many people, has a soft spot in his heart for the Commodore 64. He prefers to play his C64 games on his computer nowadays, but likes using his old school Competition Pro rather than some modern controller with remapped buttons. The only problem with using the controller is that his new computer doesn’t [...]

[Bill's] worked on his homebrew computer for almost a decade. He didn’t start with a Z80 processor like a lot of the projects we’ve seen, but instead build the CPU itself from 74-series TTL chips and a ridiculous amount of wire wrapping to connect it all. The video after the break shows off the functionality. [...]

Instructables user [Mike Craghead] was in the middle of building a very compact public computer kiosk when he ran into a problem with the processor fan. It was too big for the enclosure and had to be swapped out with a fan that did not allow the motherboard to monitor its rotational speed. Motherboards don’t [...]

Instructables user [bkovac] was sick of clicking the terminal icon on his desktop whenever he wanted to launch a terminal window. Keyboard shortcuts aside, he figured the easiest way to take the tedium out of the process would be to launch terminal windows with a foot pedal. He grabbed a pedal that he had sitting [...]

shackspace member [@dop3j0e] found himself in a real bind when trying to recover some data after his ThinkPad’s fingerprint scanner died. You see, he stored his hard drive password in the scanner, and over time completely forgot what it was. Once the scanner stopped working, he had no way to get at his data. He [...]

[John W. Linville] wrote a digital video player for the Tandy Color Computer (aka TRS-80). The decades-old hardware performs quite well considering the limited resource he had to work with. This is the second iteration of his player, and can be seen after the break playing a promo video for CoCoFEST 2011 where he’ll show [...]

You may not have ever thought about it, but the far-too-often-used keyboard combination of Control + Alt + Delete had to have been brought into existence by some random coder at some point in technological history. But wait, it wasn’t just a random coder. The keystroke combo is attributed to [David Bradley]. He was one [...]

[Didier Stevens] wrote in to tell us about a little piece of PC security software he put together recently. His application, LockIfNotHot, works in conjunction with your PC as well as an IR temperature sensor in order to lock your computer the moment you step away. The theory behind the system is pretty simple. Basically, [...]

[Viktor] decided to replace his old power hungry home server with a model that is much easier on the old electric bill. The new motherboard uses an Intel Atom chip and consumes far less power than its predecessor. He figured there was no reason to use a bulky ATX power supply when all he needed [...]

Ask anyone who has ever owned a car with a manual gearbox – in real life and in video games, nothing beats stick shift. Rather than shell out gobs of money to purchase a pre-made shift box, forum member [nikescar] built his own for about $20. Using some scrap wood and a plastic cutting board, [...]
