Hackaday Superconference is just a week away (precious few tickets remain), a celebration of all things Hackaday, which naturally includes creative projects making the most of their hardware. Every attendee gets a platform for hacking in the form of the conference badge.
To make the most of your badge hacking fun, plan ahead so you will have the extra components and the tools you need. At the most basic, bring along a serial to USB cable and a PIC programmer. These are common and if you don’t own them, ask around and you will likely be able to borrow them. Now is also the time to put in a parts order for any components you want to use but don’t have on hand!
The badge is hackable without any extras, but it’s designed for adding hardware and hacking the firmware. We’re excited to see what you can do with it. We gave an overview of this retro themed pocket computer a few days ago, today we’re inviting you to exploit its potential for your hardware hacks.

Back in 2014 [Johan] decided to celebrate BASIC’s
30 50 year anniversary by writing his own BASIC interpreter. Now, a few years later, he says he feels he has hit a certain milestone: he can play Flappy Bird, written in his own version of BASIC, running on his own home-built computer, the BASIC-1.
Inside the BASIC-1 is an Atmel XMega128A4, a keyboard from a broken Commodore 64, a joystick port, a serial to TV out adapter, and an SD card adapter for program storage. An attractively laser-cut enclosure with kerf bends houses the keyboard and hardware. The BASIC-1 boots into BASIC just like many of its home computer counterparts from the 80s.

This Arduino BASIC interpreter will make a really fun one-day project if you’ve already got the parts on hand. [Usmar A. Padow] put together an Arduino Uno, SD card, four line character LCD, and PS/2 keyboard. but he’s also included alternative options to go without an LCD screen by using a computer terminal, or without the SD card by using only the Uno’s RAM. As you can see in his demo after the break, this simple input/output is all you need to experiment with some ancient computing.
It’s hard for us to watch this and not think back to an orange or green monochrome display. Just like decades past, this implementation of BASIC has you start each line of code with a line number, and doesn’t allow for character editing once the line has been input. The example programs that [Usmar] shows off are simple to understand but cover enough to get you started if you’ve never worked with BASIC before.
Last August we saw another hack which ported Tiny BASIC to the Arduino. You may want to take a gander at that one as well.

[Mike] sent in a project he’s been working on – a port of a BASIC interpreter that fits on an Arduino. The code is meant to be a faithful port of Tiny BASIC for the 68000, and true to Tiny BASIC form, it fits in the very limited RAM of the Arduino.
True to Tiny BASIC’s assembler roots, [Mike]’s C port makes extensive use of the “infinitely-abusable” goto statement. Kernighan and Ritchie said themselves, “code involving a goto can alway be written without one” but [Mike] found that using goto left a lot more room available for BASIC code. The BASIC interpreter eats up around 600 bytes in the Arduino RAM, leaving about 1.4 kB for BASIC code. Not much, but more than the lowest-end BASIC Stamp.
[Mike] says he started this project to see how ‘old bearded ones’ conjured up so many impressive programs with a few kB of RAM. Tiny BASIC was originally conceived for the Altair 8800 that shipped with 256 bytes of RAM stock, so it seemed like a perfect fit. Right now, all we know is we’ll be spending the weekend digging through our copies of Dr. Dobb’s Journal.
