C64 Interface For Your Computer

January 23, 2010 by Caleb Kraft 24 Comments

Before we get started, lets just point out that this C64 was broken. He did not take a functional C64 out of operation for this. What he did do, was to build a hardware interface for for his VICE system. For those unfamiliar, VICE is a cross platform C64 emulator. [Simon] points out that the old games just weren’t as much fun without the original hardware. Having a broken C64 lying around, he put it to good use. It now acts as the interface for all the original fun stuff.

If you are a fan of the hardware, but just want to interface it as a normal USB keyboard, that is possible as well.

Ideas Based On Photo Frame Clock

January 23, 2010 by Mike Szczys 28 Comments

[Mahto] bought a digital picture frame but the image quality turned out to be terrible. He decided to turn it into a clock in a unique way. He loaded up 720 images, one for each minute in a twelve hour period. He then used an Arduino to simulate a button once a minute, cycling to the next image.

This is a simple solution and it works. Visions of hardcore hacks danced through our head when we first looked at this. We’re wondering if there is a way to inject image data into the frame’s memory? How about rewriting the SD card location where the image file that’s currently being displayed is stored, then having the frame reload the picture? Those are projects for a snowy weekend, but we’re sure that [Mahto] finished this hack long before we would have because he kept it simple.

Sooner or later we’re going to need a category for all of these clock hacks.

LCD Backlight Repair

January 22, 2010 by Mike Szczys 13 Comments

Another broken LCD TV came [Steve DiRaddo’s] way. This one had a broken backlight that he wanted to fix. He scrapped his LCD light table in order use the inverter. The two televisions were not the same size, nor made by the main manufacturer, but backlights all operate under the same principles. Using an inverter from a bit larger model meant it would have enough power to illuminate the lamps but he knew there’d be a problem with connectors and pinouts. After a bit of testing and creative wiring he got the system back up and running.

He’s got some extra parts left over from each TV including a bunch of CCFL lamps. Sound like it’s time to add some ground effects to his bike.

Hardware Store Follow Focus

Want to do quick and accurate focus change with your DSLR? Here’s a discussion thread covering dirt-cheap solutions. It starts with a broccoli rubber-band and a couple of zip ties. That being a bit chintzy, the more popular build seen above uses a hose clamp, rubber band for padding, a drawer pull, a nut, and some threaded rod. If you build it, be very careful not to over-tighten the clamp and crush your focus ring! After the break we’ve embedded a video of what follow focus looks like through the lens and what is happening with the camera during the shoot.

Hack Together A Coffee Roaster

January 22, 2010 by James Munns 14 Comments

For most people, making coffee entails taking a couple scoops out of a can of pre-ground coffee, adding water, and pressing “Go” on the drip machine. To others coffee brewing is an artform, and want as much control over the process as possible. For those without an overflowing bank account for a home roasting machine, Evil Mad Scientist Labs have put together a general guide for throwing together a Coffee Bean Roaster and cooler (which is apparently just as important as roasting) from a low cost hot air popcorn popper. The home roasting scene is even big enough to warrant its own Wikipedia page, which also mentions using a popcorn popper as a bean roaster.

The guide includes some great simple circuit diagrams to keep in mind when hacking your own, as well as a good explanation why you shouldn’t just clip out the heating coil for cooling mode.

Electric Go Cart From Trash

January 22, 2010 by Caleb Kraft 33 Comments

A quick lesson on being a good parent. If you make an awesome electronic cart out of trash that may not necessarily be stable, or even fully capable of stopping once it gets going, you MUST put your children on it and insist that they drive. Did we mention that the system is full acceleration or no acceleration? Indeed, it is. There isn’t a writeup, and one really isn’t needed. This is dead simple. The parts list will explain most of what is going on, but the look of doubt and fear on the kids face is what really makes this hack worth it. Or is that possibly a look that says “what are you looking at?”

Simple Laptop Conversion

January 22, 2010 by Caleb Kraft 16 Comments

[Jakob] sent in his method of dealing with broken laptop hinges. Broken hinges are a plague. We have no less than 4 laptops lying around that are beyond repair with broken hinges. Some are just propped up against things, some have had box hinges glued to them and some are just waiting to die slowly from non use. [Jakob] has a nice neat conversion where he basically made a tablet. We’ve seen that before as well as picture frames. His version, while being quite possibly easier than most of the others, has a neat design aspect. An extended lip at the bottom fits in a groove in a plastic slab. All in one PC becomes a tablet in an instant. Not too shabby for a broken laptop. It looks like he needs to pop a touch screen kit on it though.
