Someone’s Made The Laptop Clive Sinclair Never Built

Posted on by

The Sinclair ZX Spectrum was one of the big players in the 8-bit home computing scene of the 1980s, and decades later is sports one of the most active of all the retrocomputing communities. There is a thriving demo scene on the platform, there are new games being released, and there is even new Spectrum hardware coming to market.

One of the most interesting pieces of hardware is the ZX Spectrum Next, a Spectrum motherboard with the original hardware and many enhancements implemented on an FPGA. It has an array of modern interfaces, a megabyte of RAM compared to the …read more

Making A Motorized Turntable Portable

Posted on by

[Robin Reiter] needed a better way to show off his work. He previously converted an electric TV stand into a full 360-degree display turntable, but it relied on an external power supply to get it spinning. It was time to give it an upgrade.

Putting his spacial organization skills to work, [Reiter] has crammed a mini OLED display, rotary encoder, a LiPo 18650 battery and charging circuit, a pair of buck converters, a power switch, and an Arduino pro mini into the small control console. To further maximize space, [Reiter] stripped out the pin headers and wired the components together …read more

Magnetic Tape Storage May Not be Retro

Posted on by

Magnetic storage is quickly becoming an antiquated technology but IBM may have given it a few more years. Currently, magnetic storage is still manufactured as hard disk drives (HDDs) but you won’t find a tape drive in a modern consumer computer. That’s not likely to change but IBM is pushing the envelope to make a tape drive that will be smaller and more economical than other massive storage options. In many ways, they’re the antithesis of solid state drives (SSDs) because tape drives are slow to retrieve data but capable of holding a lot inexpensively.

Three advances are responsible for …read more

Portable Stir-Fry Range

Posted on by

If you love a good stir-fry, you know that it can be a challenge to make on your stove at home. Engineer gourmet and Youtuber [Alex French Guy Cooking], in collaboration with [Make:], whipped up a portable range capable of making delectable stir-fry.

There are three major problems when it comes to cooking stir-fry: woks are typically unstable on normal burners, those burners don’t tend to heat from a center point out, and they usually aren’t hot enough. [Alex]’s 12,000BTU portable stove is great for regular applications, but doesn’t cut it when it comes to making an authentic stir-fry.

Camp Kitchen Kit For Food On The Go!

Posted on by

Camping and road trips are a heck of a lot of fun, despite lacking many of the creature comforts that come from a house and its amenities. We’re all for fire-cooked meals, but sometimes, you want a cook-top and a sink to make cooking on the go a quick process. What if you could pack up a kitchen into a box and take it with you?

[pointblankjustice]  — opting for overkill — built this for his girlfriend instead of the requested box to simply store camping supplies. Glued and screwed plywood forms the frame, drawers, and lid which was then …read more

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
