N64 Advance Portable Gaming System

Like many people [Kyle] loves the Nintendo 64 and decided he wanted a portable version of his beloved console so he could play games while on the move.  One year, two PSOne screens, and three N64 consoles later, his vision is complete.  A Game Boy Advance travel case was gutted and used to house the console, hence the “N64 Advance” moniker.  Like many others, his project uses a PSOne screen for the display, and a Li-Poly battery pack that provides up to 3.5 hours of playing time.  He made sure to include other members of the Nintendo family in his build by adding a pair DS Lite speakers to the mix.

This build also includes some nice “extras” such as having the N64 RAM expansion pack built-in, headphone and A/V out ports (with a screen kill-switch for TV use), and an external controller port that can be used by either the first or second player. Be sure to check out the video of his build after the jump.

Steampunk CD Player

February 5, 2011 by 29 Comments

This custom CD-player enclosure may not be your style, but you can’t deny that the fabrication techniques are top-notch (translated). This starts with a portable CD player and a set of amplified speakers. A brass plate serves as the base for the electronics, with the CD player internals mounted from the underside. The brass dome that covers the spinning disk also started as a sheet of metal, with quite a bit of work (translated) going into shaping and smoothing to achieve these results. The base and speaker boxes exhibit some fine woodworking, and there’s even additional electronics for lights, control buttons, and to drive the two analog meters. A lot of thought went into each component of this build and that’s how you put together a masterpiece.

Custom Enclosures Made Of Paper

February 5, 2011 by 47 Comments

[Sivan Toledo] needed a enclosure for a unique sized electronic project, not finding what he needed in off the shelf solutions, he went to the next best thing, … Papier Mâché!

Using a mold made out of standard corrugated cardboard, he slowly built up layers made of magazine paper, and ordinary “white glue” diluted with water. After getting near the thickness wanted he switched over to typing / copy type paper for a nice clean outer surface. Ports were made in the usual fashion when dealing with soft or thin material, drill a smaller hole, going back with successively larger holes, and then follow up with an appropriate file, all while taking things slow along the way to prevent unwanted results. Finishing up with layers of paper carefully cut into strips to meet the circumferences / edges, along with the final outer surface to make it all even.

The end result is awesome as it stands, but we cant help but wonder what some sanding and paint would look like on a enclosure made like this, though any way you finish it, the idea comes down to custom enclosures that do not need special tools or materials to complete (on the cheap).

Thanks [Drone]

8×8 LED Infinity Mirror

February 5, 2011 by 6 Comments

[chromationsystems] put out a couple instructibles on building infinity mirrors. One with an 8×8 array of LEDs and one with a 32 LED ring. These are very well  documented covering the construction of the mirror enclosure as well as the circuit and code. The effect is quite nice. The 8×8 array is interesting, we haven’t seen that before. These would make a fine addition to any geek cave/electronics lab. While it looks like these were basically advertisements for a product he sells, you can definitely make your own from his instructions. We like this kind of advertising.

Homebrew Mp3 Player With Some Bonus Features

February 4, 2011 by 16 Comments

When [falldeaf] set about making his own homebrew Mp3 player, he ended up at the same place we most do while looking into the subject, the wonderful Minty Mp3. Basing the design on [Adafruit Industries] popular board, we are presented The Mp3 Garbler.

First change of the project was to replace the sometimes difficult to find ST013, or the more expensive ST015T Mp3 decoder chip, and the CS4340 digital to analog cconverter with a single vs1001k, which we have checked out before. And while yes VLSI says that the 1001 series is a discontinued product, and it may be a bit hard to find now days, they also offer an updated model on their website, which should suit the application fine.

Next up is a useful LCD display sporting a Sparkfun lcd backpack, that shows us all the important to know music info. And finally there is a 10×14 led matrix display, that can be used to display all sort of user feedback icons, and is driven by a MAX6953, which we think is a pretty spiffy chip.

While there is no schematic, there are brd files, and source code available for your PIC18F452 or similar micro controller to complete your own

Analog Computer Does Math

February 4, 2011 by 14 Comments

This analog computer can multiply, divide, square numbers, and find square roots. It has a maximum result of ten billion with an average precision of 2-3%. [Miroslav’s] build recreates something he saw in a Popular Electronics magazine. It uses a resistor network made up of three potentiometers with a digital multimeter is an integral part of the machine. To multiply a number you set the needles on the first two knobs to the numbers on which you are operating. To find the result turn the third knob until the multimeter has been zeroed out and read the value that knob is pointing to. It seems much more simple than some of the discrete logic computers we’ve seen, yet it’s just as interesting.

Touch Sensors: Overview, Theory, And Construction

February 4, 2011 by 21 Comments

This collection of touch sensor information should be of interest to anyone who liked the simple touch sensor post from Thursday. That was a resistive touch sensor and is covered in detail along with AC hum sensors that trigger based on induced current from power lines around you, and capacitive touch switches like we’ve seen in past hacks. Each different concept is discussed and clearly illustrated like the slide above. [Giorgos Lazaridis] has also put together individual posts that build and demonstrate the circuits. We’ve embedded his resistive sensor demo video after the break and linked to all three example circuits.
