8-bit Computer for On-The-Go Programming

Posted on by

If there was one downside to 8-bit computers like the Commodore 64, it’s that they weren’t exactly portable. Even ignoring their physical size, the power requirements would likely have required a prohibitively large power bank of some sort to lug around as well. The problem of portability has been solved since the late ’70s, but if you still want that 8-bit goodness in a more modern package you’ll have to look at something like retrocomputing madman [Jack Eisenmann]’s DUO Travel computer.

The computer is based around the ubiquitous ATmega328 which should make the ease at which it is programmable apparent. …read more

Portable Jacob’s Ladder for When…You Know… You Need a Portable Jacob’s Ladder

Posted on by

When do you need a portable Jacob’s Ladder? We don’t know, but apparently [mitxela] doesn’t want to leave home (or the laboratory) without one. So he built a portable unit that works for a few minutes on a battery. In the video (see below), he says he wouldn’t presume to claim it was the smallest Jacob’s Ladder ever, but he thought it might be a contender.

The battery is a LiPo cell and although it might last up to four minutes, [mitxela] points out that the transistors probably wouldn’t survive that much on time, despite the heat sinks he put …read more

Go Portable with GameCube Advance SP

Posted on by

Off the hop, we love portable consoles. To be clear, we don’t just mean handhelds like the 3DS, or RetroPie builds, but when a maker takes a home console from generations past and hacks a childhood fantasy into reality — that’s amore. So, it’s only natural that [Bill Paxton]’s GameCube re-imagined as a Game Boy Advance SP has us enthralled.

Originally inspired by an early 2000’s imagined mockup of a ‘next-gen’ Game Boy Advance, [Paxton] first tried to wedge a Wii disk drive into this build. Finding it a bit too unwieldy, he opted for running games off of SD …read more

Portable Bluetooth Speaker Reacts to Sound

Posted on by

[IanMeyer123] should be working on his senior design project. Instead, he’s created a sound-reactive Bluetooth speaker that may not earn him an A grade but will at least keep the team entertained.

[Ian] started with the amp and power. The amp is a 15 watt, 12 volt model based on the popular TDA7297 chip. Power comes from a portable laptop battery rated at 185 Wh. [Ian] himself said that is absolute overkill for this project. While [Ian] hasn’t run any longevity tests on his setup, we’re guesstimating it would be rated in days.

Every Bluetooth speaker needs a sweet light …read more

Portable RetroPie Suitcase For Multiplayer On The Go!

Posted on by

Portable gaming — and gaming in general —  has come a long way since the days of the original Game Boy. With a mind towards portable multiplayer games, Redditor [dagcon] has assembled a RetroPie inside a suitcase — screen and all!

This portable console has almost everything you could need. Four controllers are nestled beside two speakers. Much of the power cabling is separated and contained by  foam inserts. The screen fits snugly into the lid with a sheet of rubber foam to protect it during transport.

Tucked behind the monitor rests the brains of this suitcase console: a Raspberry …read more

Portable RetroPie Builds on the Shoulders of Giants

Posted on by

For anyone wanting to get that shot of nostalgia without the hassle of finding an NES Classic, the Retropie project is a great starting point. Of course, it’s not too noteworthy to grab a Raspberry Pi, throw a pre-built distribution on it, and plug in an SNES to USB converter. What is noteworthy, however, is building a Retropie that’s portable and that has the quality and polish of the latest build from [fancymenofcornwood].

For starters, the laser cut wood case was custom-made. From there, all of the PCBs were fitted including specific ones to handle each set of buttons (complete …read more

Battery Powered Fog Machine Just in Time for Halloween

Posted on by

[makendo] needed a portable fog machine for an upcoming project. It seemed like the kind of a thing a liberal application of money on the Internet could fix in no time. But quality fog machines are too expensive, and the cheap machines are just, well, cheap. Stuck between $800 and quickly broken crap, he decided instead to fashion his own.

Fortunately for him, a recent fad has made it so that a certain segment of the populace absolutely require dramatic clouds of scented drug fog or they get cranky. The market saw an opportunity, cost optimized, and now there are …read more

Portable Lightweight Foundry

Posted on by

[Makercise] is getting ready for Maker Faire. One of the things he’d really like to do is some casting demonstrations. However, he has no desire to take his expensive and heavy electric kiln based foundry to Maker Faire. So, he made his own.

He got into metal casting during his excellent work on his Gingery lathe series. He started off by modeling his plan in Fusion 360. He’d use a 16qt cook pot turned upside down as the body for his foundry. The top would be lined with ceramic fiber insulation and the lid made out of foundry cement. He …read more
