This Handheld C64 Design Study Needs To Be Made

The Commodore 64 remains the best selling home computer of all time, and is unlikely to be toppled anytime soon. It continues to inspire a diehard community of makers and hackers to this day. [Cem Tezcan] is one of those people, and his design study of a handheld C64 is utterly droolworthy.

It’s quite likely that you’d run out of power before the cassette finished loading, but hey, we can dream.

The study includes renders of the device from several angles, as well as a basic blueprint outlining the various components. It features period accurate hardware, using a membrane keyboard, micro-cassettes for data storage, and a 3.5″ CRT. Other nice touches are the big red textured FIRE button, and a horrible early 80s 3.5mm jack.

The C64 hardware of the time required both 12 V and 5V power, and the current draw of even a small CRT would be high. It’s likely such a handheld would have battery life measured in minutes. It’s a wonderful picture of what could have been, though we suspect that such a design would have pushed the limits of the technology of the time.

However, electronics has matured since, and we sit here rather comfortably in 2019. We’d love to see the best handheld C64 that the community can muster, and with 3D printers and FPGAs on hand, it’s an eminently achievable feat. Bonus points to anyone who can make a microdatasette interface, too. All submissions to the tips line, and meanwhile, consider how easy it is to build a new C64 from scratch. Happy hacking!

Speakers Taking The Stage At Supercon Plus A Hint Of The Hacking To Come

Four weeks from today the Hackaday Superconference comes alive for the fifth year. From engineering in challenging environments to elevating the art form of electronics, here are nine more talks that will make this a year to remember.

In addition to the slate of speakers below there are three other announcements, plus workshops. Jeroen Domburg (aka Sprite_TM) is designing this year’s badge based around a beefy FPGA running a RISC-V core and using open source synthesis tools. We’ll have more on that soon, but if you just can’t wait, check out the expansion board spec he just published, and join the conference chat room for the inside track. Badge hacking is sure to be the liveliest we’ve ever seen.

Tickets are sold out but you can still get on the waiting list and hope that one becomes available. If you are holding onto one of these hot commodities but are unable to use it, please return your ticket so that we can get it to someone waiting with their fingers crossed.

The Talks (Part Four of Many)

    When it Rains, It Pours

    Over the last two years my work has been beyond ordinary, building and prototyping in strange locations like being stranded on a sailboat in the Atlantic Ocean, teaching US Marines in Kuwait, and building fuel gauge sensors for generators for vital systems in North Carolina post hurricane Florence. Some of the big lessons I’ve learned are about how to source materials and supplies in weird places, like finding potentiometers in the backwoods of North Carolina when Amazon cannot physically deliver across flooded highways, how to find welding gas in Kuwait City (and how a local chef could possibly be your best bet), or how far you can get with an O’Reilly’s Auto Parts store near the city docks. These situations help you really see the “engineer creep” that can happen to a project. I’ve learned that when you’re in high-risk situations, you really should stop caring about whether the edges of your 3D print are chamfered. In fact, version 1 of the hurricane fuel gauge sensor was demonstrated while being housed inside an elegant, tasteful sandwich baggie.

    Building Whimsical Wearables: Leveling Up Through Playful Prototyping

    Whether it’s for a theme party, Halloween, cosplay, or That Thing in The Desert, designing wearables for whimsical self expression presents a great opportunity to challenge yourself as a maker, wearer, and collaborator. As an artist and designer who crash landed into a career in tech, I’ve found that imposter syndrome can often place limits on what feels personally achievable from an electronics and programming standpoint. Recontextualizing a project to shift the focus from ‘wearable tech hardware endeavor’ to ‘quirky mixed media experiment in personal styling’, I’ve created a safe space to play and try new things just outside my skill set and produced some of my most technically complex and polished personal work. Take a journey with me through the process of conceptualizing and building my Color Stealing Fairy project, an exercise in iterative design and upgrading an interactive wearable project over the course of two years and counting.

    Software-Defined Everything

    The popularity of Software-Defined Radio (SDR) has led to the emergence of powerful open source software tools such as GNU Radio that enable rapid development of real-time Digital Signal Processing (DSP) techniques. We’ve used these tools for both radio and non-radio applications such as audio and infrared, and now we are finding them tremendously useful for diverse sensors and actuators that can benefit from DSP. In this talk we’ll show how we use the open source GreatFET platform to rapidly develop an SDR-like approach to just about anything.

    “Hacking Nature’s Musicians” (or, “The Art of Electronic Naturalism”)

    The general lack of acceptance of electronic art results from a scarcity of critics, curators, collectors, and grantors who understand electronic media, compounded by a cultural gap between the artistic and engineering communities. In order to solve this problem, we must stretch our comfort zone and vocabularies to have a respectful, enlightening conversation with people with different educational backgrounds. In this talk I’ll discuss my wonderment at the simple, analog circuit designs that mimic life-like behavior such as chirping crickets and singing birds. This will include discussion of various schematics and demonstrations of a small. along with an abbreviated survey of my work to-date.


  • Jasmine Brackett

    Setting your Electronics Free

    In this panel we’ll discuss the key ways to get your projects from your workshop into the hands of the first few users, and what you can do to scale up from there. We’ll talk about common pitfalls, and also what are the best resources to draw upon.

    MicroFPGA – The Coming Revolution in Small Electronics

    Big FPGA’s are awesome. They’re doing what they’ve always done, enabling AI, signal processing, military applications etc. However, there is a new possibility emerging – FPGA’s for small applications – which is quite possibly even more significant. Using open source tools, cheap flexible development boards, and new libraries, designers have a whole new set of options, creating incredibly high performance, flexible, low power projects and products.


  • Nick Poole

    Boggling the Boardhouse: Designing 3D Structures, Circuits, and Sensors from PCBs

    The presentation will be a series of design features or techniques with a few minutes of exploration into the ‘gotchas’ of each, as well as example layouts in EAGLE and physical examples. I’d like to cover as many different techniques as I can cram into 30 minutes, including bringing weird shapes into EDA, the inside corner problem caused by tab and slot, fillet soldering, stacking boards, imitating model sprues with mouse bites, manipulating the mask layer for custom displays, bendy tab buttons, working rotary encoder, and ergonomic design for handheld PCBs.


  • Ted Yapo

    Towards an Open-Source Multi-GHz Sampling Oscilloscope

    Tektronix designed a 14.5 GHz sampling oscilloscope in 1968. With the easy multi-layer PCB designs, tiny surface-mount parts, blazingly fast semiconductors, and computer horsepower available to the individual designer today, can a similar sampling head be re-created inexpensively with common, off-the-shelf components? Should be easy, right? It’s not. In this talk, I’ll discuss progress towards an open-source GHz+ sampling oscilloscope, including a lot of dead ends, plus some very promising leads.


  • Jeroen Domburg

    Building the Hackaday Superconference Badge

    The tradition of the Hackaday Supercon badge is to build something unlike any Supercon badge that came before. This year’s badge has an FPGA as its central component, and this comes with some extra challenges: the FPGA only comes in a BGA package with a whopping 381 pads to solder, and instead of just referring to the datasheet of the SoC to write the badge software, the SoC itself had to be written first.  I will discuss the development process of the badge, as well as the many challenges encountered along the way.

 

Keep Your Eye on Hackaday for the Livestream

The speakers you’ll see at Supercon have an amazing wealth of experience and we can’t wait to see their talks. But even if you couldn’t get a ticket, that doesn’t mean you have to miss out. Keep your eye on Hackaday for a link to the livestream which will begin on Saturday, November 16th.

Hackaday Prize China Finalists Announced

In the time since the Hackaday Prize was first run it has nurtured an astonishing array of projects from around the world, and brought to the fore some truly exceptional winners that have demonstrated world-changing possibilities. This year it has been extended to a new frontier with the launch of the Hackaday Prize China (Chinese language, here’s a Google Translate link), allowing engineers, makers, and inventors from that country to join the fun. We’re pleased to announce the finalists, from which a winner will be announced in Shenzhen, China on November 23rd. If you’re in Shenzen area, you’re invited to attend the award ceremony!

All six of these final project entries have been translated into English to help share information about projects across the language barrier. On the left sidebar of each project page you can find a link back to the original Chinese language project entry. Each presents a fascinating look into what people in our global community can produce when they live at the source of the component supply chain. Among them are a healthy cross-section of projects which we’ll visit in no particular order. Let’s dig in and see what these are all about!

Handheld LoRa Joystick For Long-Range Bots

Wanting a simple tool to aid in the development of LoRa controlled robotic projects, [Jay Doscher] put together this very slick one-handed controller based on the 900 MHz Adafruit Feather M0. With a single trigger and a miniature analog joystick it’s a fairly simple input device, but should be just enough to test basic functionality of whatever moving gadget you might find yourself working on.

Wiring for this project is about as simple as you’d expect, with the trigger and joystick hanging off the Feather’s digital ports. The CircuitPython code is also very straightforward, though [Jay] says in the future he might expand on this a bit to support LoRaWAN. The controller was designed as a barebones diagnostic tool, but the hardware and software in its current form offers an excellent opportunity to layer additional functionality on a known good base.

Everything is held inside a very well designed 3D printed enclosure which [Jay] ran off on his ELEGOO Mars, one of the new breed of low-cost resin 3D printers. The machine might be pretty cheap, but the results speak for themselves. While resin printing certainly has its downsides, it’s hard not to be impressed by the finish quality of this enclosure.

While LoRa is generally used for transmitting small bits of information over long distances, such as from remote sensors, this isn’t the first time we’ve seen it used for direct control of a moving object. If you’re not up to speed on LoRa, check out this excellent talk from [Reinier van der Lee] that goes over the basics of the technology and how he used it to build a community sensor network.

New Life For Old Nintendo Handhelds With ESP32

The Game Boy Pocket was Nintendo’s 1996 redesign of the classic 1989 handheld, giving it a smaller form factor, better screen and less power consumption. While it didn’t become as iconic as its predecessor, it still had enough popularity for modders such as [Eugene] to create new hardware for it. His Retro ESP32 board is a drop-in replacement for the console’s motherboard and screen, giving it a whole new life.

[Eugene] is no stranger to making this kind of mod, his previous Gaboze Pocaio project did the exact same thing with this form factor, only with a Raspberry Pi instead of the ESP32-WROVER used here. His choice of integrated SoC was based on the ODROID-GO, which is a similar portable console but with its own custom shell instead.

This project doesn’t stop at the hardware though, the Retro ESP32 (previously dubbed Gaboze Express) also offers a user-friendly interface to launch emulators. This GUI code can be used with the ODROID as well since they share the same hardware platform, so if you have one of those you can try it out right now from the software branch of their repository.

If the idea of replacing retro tech innards with more modern hardware is something that interests you, look at what they did to this unassuming Osborne 1, or this unwitting TRS-80 Model 100. Poor thing didn’t even see it coming.

Handheld Game Console Puts Processing Power In The Cartridge

With the proliferation of cheap screens for use with microcontrollers, we’ve seen a matching proliferation in small handheld gaming projects. Pick your favourite chip, grab a screen off the usual suspects, add some buttons and you’re ready to go. [bobricius] has put a unique spin on this, with an unconventional cartridge-based build.

The main body of the handheld is constructed from attractive black and gold PCBs, and features a screen, some controls and an on/off switch. There’s also a microSD socket is on the board, which interfaces with cartridges which carry the microcontroller. Change the cart, and you can change the game.

[bobricius] has developed carts for a variety of common microcontroller platforms, from the Attiny85 to the venerable ATmega328. As the microSD slot is doing little more then sharing pins for the screen and controls, it’s possible to hook up almost any platform to the handheld. There’s even a design for a Raspberry Pi cart, just for fun.

It’s an entertaining take on the microcontroller handheld concept, and we can’t wait to see where it goes next. It reminds us of the Arduboy, which can even do 3D graphics if you really push it. Video after the break.
