Portable Gaming For Retro Console Lovers

There have been a fair share of portable video game console conversions over the years, but few tug at our retro-loving heart strings more than this one. Modretro forum member [Mario] constructed a fantastic looking portable Atari 2600 using a Flashback 2 Atari console clone.

He hacked apart the Flashback board to fit inside a small plastic case, then added a 3.5″ LCD screen, as well as some donated controller bits from other portable game systems. A pair of rechargeable batteries were added along with a small amplifier and speaker for sound.

While the Flashback comes with 40 games built in, he really wanted to add a cartridge port, so with the little bit of space he had left in the case, he did just that. When everything was finished, he sprayed on a few coats of retro orange paint and called it a day. Really the only thing that’s missing is some nice fake wood veneer and maybe some shag carpet.

Alien Life Form Synth Toy

We were sent [Dr. Offset’s] most recent project, a kid’s toy that is half sculpture/half noisemaker, but 100% cool. The device uses several 555 Timers and is his entry into the 555 Design Contest, which wraps up in just a few days. To really enjoy his creation, you need to suspend disbelief for a moment, and indulge the space fantasy he creates. In other words, let yourself be a kid again, if only for a few minutes.

What he has built is a containment unit for an alien life form found during an outer space exploratory mission. The creature has fused its organic bits with electronic components in order to survive in the stark, empty world it used to call home. The containment unit allows you to zap the “bug” with various frequencies to see how it reacts. The “bug” is light sensitive, so it always offers a varying experience, day or night.

It’s definitely one of the most artistically creative entries into the 555 Design Contest we have seen yet. Continue reading to see a thorough walkthrough and demonstration of his project.

Mystery Box Out Of Lego

February 23, 2011 by Kevin Dady 8 Comments

[Todd] recently completed completed his biggest LEGO project, and its pretty wild. The Mystery Box is an 8 compartment LEGO brick puzzle box, covered in a psychedelic pattern of interconnecting question marks.

The question mark pattern was inspired by a few things, the book called “The Curious Incident of the Dog in the Nighttime” contained an illustration that looked sort of like a M.C. Escher painting, which with some looking around brought up tessellation. With the look in mind [Todd] sat down with a paint program, drew out a grid, and started flood filling blocks until the pattern was perfect.

In puzzle box tradition, to gain access to the contents you must remove each compartment in the specific mystery order, and to accomplish this was no easy task. Lego Digital Designer was used to prototype everything on the box and then once happy, [Todd] broke the model down for a parts count.

Nearly 8,000 parts, 35 brick orders, and some long waits, the box was finally completed and its definetly worth a look. If you’re not that extreme, they also make cool electronics enclosures.

Amazing Backyard Rocket Ship Tree House

Ravenna_Ultra-Low-Altitude_Vehicle

If you thought you had a cool tree house as a kid, think again. Tasked with landscaping his back yard and building a tree house for his son, [Jon] decided to go all out and build him a rocket ship instead.

Rising 15 feet into the Seattle skyline, the tree house known as the Ravenna Ultra-Low-Altitude Vehicle (RULAV), is sure to be the envy of every kid in the neighborhood. [Jon] and a friend worked for well over a year on their creation, welding, grinding, painting, and riveting their way along. After the structure was built, they fabricated some custom PCBs, using them to build the ship’s 14 control panels. The entire operation is controlled by a custom OS built to run on the three ATmega MCUs that manage operations.

Not content with just a handful of knobs and switches, the ship contains over 800 LEDs among its laundry list of electronics goodies. Compressed air is used to shoot water from positioning “thrusters”, while a paint mixer spins under the ship to simulate the rough and bumpy nature of space travel. The simulated launches are capped off with plenty of authentic NASA-style audio and a sub woofer that gives everything a deep, resonating rumble.

The project is truly amazing, and a ton of work went into every little detail in order to make this the most spectacular tree house ever seen. [Jon] definitely takes the award for “Coolest Dad Ever” for this build, even we’re jealous!

The pictures certainly don’t do it justice, so be sure to check out the video below for a quick introduction and demo of this awesome project.

Thanks to [Jeremy Elson] for the tip.

Toy Helicopter Charging Fix

February 20, 2011 by Mike Szczys 16 Comments

[Onefivefour] was surprised that his E-flite Blade MCX radio controlled helicopter came with a charger that used AA batteries to recharge the lithium batteries in the flying unit. Yeah, that’s a bit crazy. He set out to modify the base unit to work with AC power. There are four batteries inside this base unit, one of them powers the charge detector circuit and the others are used to juice-up the chopper’s rechargeable cells. He took a 5V regulated charger from a Motorola cellphone and modified it to interface with the contacts for the three AA cells. Like the Magic Trackpad hack, he did this without altering the holder by cutting a couple of pencils to length and attaching the positive and negative contacts from the AC charger to them. Check out the video after the break for a walk though, noting how he still has the option to go back to battery power if he so chooses.

Bluetooth Tomy Omnibot Hack

[DJ Sures] sent us his most recent hack, and it’s one that is sure to please those who enjoy a good dose of 80’s nostalgia. He located a Tomy Omnibot on eBay and snatched it up immediately. While he was waiting for it to arrive, he planned out what he would add to it once it showed up at his door. Once the robot was delivered, he cleaned it up, painted it, then got down to business.

The original robot had no ability to move its arms or head, so he immediately added servos to enable those actions. A wireless camera was inserted between the Omnibot’s eyes, and a wireless mic was mounted in his chest. He has also added some features found in his previous projects, such as voice recognition, visual recognition, voice synthesis, and the ability to remotely control the bot. He plans on adding an ultrasonic ping sensor and IR floor sensors in the near future. This is a great build so far, and it sounds like he has plenty more in store.

Be sure to stick around for a video of the robot in action, and if you are interested in some of [DJ Sures’] previous work, check these out as well.

Hacking Teddy Ruxpin

February 18, 2011 by Mike Szczys 17 Comments

[DJ Sures] got his hands on a broken Teddy Ruxpin doll and decided to give it a new robotic life. You may want to ask the children to leave the room before viewing the video after the break. It starts right off with little Teddy having his throat slashed in order to get at the parts in the head. After retrofitting the eyes, mouth, neck, and arms with servos, Teddy gets a Bluetooth upgrade that lets you control his movements wirelessly. [DJ Sures] even has plans to get the little guy up and walking, far exceeding the original capabilities.
