Fresh hacks every day
The accuracy which [Mario] achieved in his pen plotter dot matrix printer is very remarkable. He tore through a pile of floppy drives to get the parts he wanted, and chose to go with a fine-point Sharpie marker as a print head. In the video after the break he flatters us with a printout of the Hackaday logo, but you … Read the rest
At first look we thought this was a plotter, but it’s really more of a dot matrix (or line matrix) printer. [Bruno] whipped this up using parts from a DVD optical drive. It is capable of moving the pen along the Z and X axes, and feeding the paper along the Y axis.
The video after the break shows … Read the rest
In the days when computers took up an entire room, a CRT monitor was a luxury. Most of the time, input and output was handled with a teletype – a typewriter connected directly to the computer. [Josh] wanted his own typewriter terminal, so he took apart an IBM Selectric II and got to work.
Instead of an electronic keyboard, the … Read the rest
Whether it’s building a 3D scanning system with a Kinect, or using a USB TV tuner dongle for software defined radio, there are a lot of interesting off-schedule uses for commodity hardware. The latest comes from the fruitful mind of [sjMoquin] and a Lexmark N2050 WiFi card that runs Linux.
This build started off with a Lexmark X6570 all-in-one printer … Read the rest
[Jim's] pretty serious about his Etch a Sketch. He’s gone to the trouble of building a rig that will automatically render a photograph as Etch a Sketch art. Do you recognize the US political figure being plotted in this image? He actually cracks these open and removes all of the internals to preserve the artwork when the reassembled body … Read the rest
When it comes to making PCBs at home really quickly, there’s not much to improve upon with [Ryan]‘s bodged up Epson printer that prints an etch mask directly on a piece of copper clad board.
Like most of the direct to copper PCB printer conversions we’ve covered ( 1, 2, 3 ), [Ryan]‘s build relied on an Epson … Read the rest
The laser printer portion of this all-in-one machine gave up the ghost and [Entropia] couldn’t get it working again. But the scanner was still functioning so he decided to separate the scanner from its dead printer module.
The model in question is a Samsung SCX-4200. The design is actually perfect for separation because the scanner sits on top of … Read the rest
