Toy Television’s Dreams Come True

A couple of years ago, [Alec]’s boss brought him a souvenir from Mexico City—a small mid-century console television made of scrap wood and cardboard. It’s probably meant to be a picture frame, but [Alec] was determined to give it a better life.

As it turns out, the screen of [Alec]’s old Samsung I9000 was a perfect fit for the cabinet with room to spare. It was on its way to becoming a real (YouTube) TV once [Alec] could find a way to control it remotely. A giant new-old stock remote that’s almost bigger than the TV was just the thing. There’s enough room inside the remote for a non-LE Bluefruit module, which is what the I9000 will accept as input without complaint.

Trouble is, Bluefruit doesn’t support matrix keypads, so [Alec] used a bare ATMega328 running on the internal clock. Since the Bluefruit board provides voltage regulation, the remote was able to keep its native 9V power. [Alec] is happy with the results, though he plans to refine his button choices and maybe make a new overlay for the remote. Stay tuned for a tiny TV tour.

A Mountain of Prizes For Projects Using These Parts

Here’s your chance to bring some great stuff home from The Hackaday Prize. For the next 3 weeks we’ll be looking for the best entries using Atmel, Freescale, Microchip, and Texas Instruments parts.

Each of the four contests (yes, four running concurrently) will award the top 50 projects. That’s 200 in total being recognized. The odds are really in your favor — currently some of those lists have less than 50 projects on them — so enter yours right away! Scroll down to see the mountain of prizes that we have for this epic run.

Make Sure We Know About Your Entry

There are two things you need to do to be eligible for this pile of awesome stuff:

  1. Enter your project in the 2015 Hackaday Prize
  2. Leave a comment here with a link to your project and we’ll add it to the list

Do this by the morning of Monday, June 29th to make sure you’re in the running. We’ve been diligent about adding entries to the lists for Atmel, Freescale, Microchip, and Texas Instruments but at the rate new entries have been coming in it’s easy to miss one here or there. Don’t be bashful about asking to be added to these lists!

The prerequisite is to be using a part from one of these four manufacturers. We’ll be looking at these lists for projects using great ideas which have also been well-documented. Tells us why you’re building it, what it does, how you came up with the idea… you know, the whole story!

The Loot

Up for grabs in each of the 4 contests are:

3x Mooshimeters which is a multimeter that uses your smartphone as a wireless readout.

2x DS Logic analyzers which [Adam] reviewed a few weeks back.

15x Stickvise to hold your PCBs (and other things) in place while you work

A continuation of what we’re giving away in each of the 4 contests:

10x Bluefruit LE Sniffers to help you figure out what’s being transmitted by your BTLE devices

10x Cordwood Puzzles; grab your iron and tackle this head-scratching soldering challenge

10x TV-B-Gone is an iconic invention from [Mitch Altman]; one button turns off all TVs

Atari 2600 Controller Now Controls CNC Plasma Cutter

When using any CNC machine the system has to understand where the part to be machined is physically located. This is most commonly done by jogging the tool to a position relative to the part and then indicating to the controller that the tool is indeed at that position. Hobby CNC enthusiasts [Jeremy] and [Yakob] wanted an easy, convenient (and even fun) way to zero their plasma cutter. They decided to make a wireless jog pendant capable of moving and zeroing their machine….. and it’s built into a retro game controller!

The housing is a wireless Atari 2600 controller. Most of the innards were taken out and replaced with a BlueFruit EZ-Key module that takes input signals from the stock joystick and button switches and, in turn, emulates a Bluetooth keyboard signal that is understood by a PC. Most PC-based CNC Control Software’s have keyboard shortcuts for certain functions. This project takes advantage by using those available keyboard shortcuts by mapping individual pin inputs to specific keyboard key presses.

The X and Y axes are controlled by pushing the joystick in the appropriate direction. Pressing the ‘fire’ button zeros the axis. Even though the remote is working now, these two guys want to add a rotary encoder so that they can make minor Z axis height adjustments on the fly since sometimes the metal they are plasma cutting isn’t completely flat.

Announcing Adafruit’s Bluefruit


You always meet the most interesting people wandering around Maker Faire, but by far the most interesting was Hackaday’s founder, [Phil Torrone] and bubblegum-haired compatriot [Limor] from Adafruit. They were out in full force checking out the sights and gave us the scoop on a new piece of hardware they’re releasing called Bluefruit.

Bluefruit is a very tiny and very cheap Bluetooth module breakout board that allows anyone to take 12 digital inputs and turn them into a Bluetooth HID device. If you’re planning a portable battery-powered arcade controller, just plug in a Bluefruit, set up your keypresses in your software, and rock out.

On board the Blufruit are an FTDI programming connector, 12 input pins, a few power pins, a custom FCC and CE certified CSR Bluetooth module, and that’s about it. If you’re looking for a simple GPIO to Bluetooth adapter without an overwrought Arduino setup, this is the best solution we’ve seen by far. Adafruit is also rocking their own custom firmware for the device, so this will be extremely hacker-friendly.

The price will be $20 and should be available in the Adafruit store in a bit. If you’re looking for an easy way to put a Bluetooth HID controller in your next project, this is the one.
