Battletech Case Mod Displays Awesome Woodwork, Hides Hacks

May 19, 2016 by 25 Comments

[S.PiC] has been working on a computer case styled to look like the Vulture mech from Battletech. We’re not sure if his serious faced cat approves or not, but we do.

The case is made from artfully cut plywood. We kind of hope he keeps the wood aesthetic. However, that would be getting dangerously close to steampunk. So perhaps a matching paint job at the end will do. In some of the videos we can how he’s cleverly incorporated the computer’s components into the design of the case. For example, the black mesh on the front actually hides the computer’s power supply intake fan.

The computer inside is a small micro-itx formfactor one. Added as peripherals to it [S.Pic] has pulled out the hacker-electronics-tricks bible. From hand soldered LED grids to repurposed Nokia LCD screens, he has it all. In one video we can even see the turret of the mech rotating under its own power.

It looks like the build still has a few more steps before completion, but it’s already impressive enough to be gladly worth the useful table space consumed on any hacker’s desk. Video after the break.

A Nokia Shield For The Arduino

May 21, 2015 by 17 Comments

The Nokia 3100 is a classic in the circles we frequent. The LCD in this phone is a very cheap and very common display, and it was one of the most popular phones since the phone from Bell, making it a very popular source of cool components.

Now everything is an Internet of Thing, and cellular data for microcontroller projects is all the rage. [Charles] thought it would be interesting to use the famous Nokia 3100 to transmit and receive data. After battling with some weird connectors, he succeeded.

The Nokia 3100 doesn’t have a USB connector, as this phone was made before the EU saved us from a menagerie of cell phone chargers. Instead, this phone has a Nokia Pop-Port, a complex connector that still has TX and RX pins running at 115,200 bit/s 8N1. By fitting a USB socket onto a prototyping board, adding a few level shifters, and connecting the pins in the right order, [Charles] was able to get his Arduino talking to an old Nokia Brick.

[Charles] isn’t quite at the level of sending SMS from his confabulation, and even following a tutorial from [Ilias Giechaskiel] didn’t work. [Charles] is looking for help here, and if you have any suggestions, your input would be appreciated.

There is a problem with using a Nokia 3100 as a cheap Arduino cellular shield: it’s only 2G, and sometime soon those cell towers will be shut down. For now, though, it works, and once those 2G towers are shut down, there are plenty of options with cheap, early Android and iOS phones.

Controlling Nokia Phones With Arduino

January 1, 2015 by 10 Comments

While [Ilias Giechaskiel] was waiting for his SIM900 shield to arrive, he decided to see what he could do with an old Nokia 6310i and an Arduino. He was researching how to send automated SMS text messages for a home security project, and found it was possible to send AT commands via the headphone jack of Motorola phones. But unfortunately Nokia did not support this, as they use a protocol known as FBus. With little information to go on, [Ilias] was able to break down the complicated protocol and take control with his Arduino.

With the connections in place, [Ilias] was able to communicate with the Nokia phone using a program called Gnokii — a utility written specifically for controlling the phone with a computer. Using the Arduino as an intermediary, he was eventually able tap into the FBus and send SMS messages.

Be sure to check out his blog as [Ilias] goes into great detail on how Nokia’s FBus protocol works, and provides all source code needed to replicate his hack. There is also a video demonstration at the end showing the hack in action.

NES Cartridge Hack Makes Great Novelty Gift

NES cartridge with arduino

Most all of us recall the Blinking Screen of Death on original NES systems. This was caused by a bad connection between the cartridge and the NES cartridge connector. For whatever reason, it became a very popular idea to give a quick blow down the cartridge, even though this didn’t really help. [Dale] decided to play on this annoying problem by making the NES Blow Cart!

Inspired by a previous cartridge hack, [Dale] mounted a custom made circuit sporting the ever popular ATtiny85 in a Super Mario / Duck Hunt cartridge. A small microphone sits where the original cartridge connector was, along with the on/off switch and program header. A quick blow triggers the ATtiny85 to play a song.

The most difficult part for [Dale] was to figure out how to get the ATtiny to play “music”. This was solved with the discovery of a library called Rtttl. This allowed him to take old Nokia Super Mario and Zelda ringtones and get them on the Attiny85. All files, including the rtttl library are available on his github. Be sure to stick around after the break for a video of the project in action.

Arduino-Based Power Failure Alert System

November 17, 2013 by 23 Comments

arduinoPowerFailBox

When the power went out at his parents’ shop and ruined the contents of their fridge, [Lauters Mehdi] got to work building a custom power failure alert system to prevent future disasters. Although some commercial products address this problem, [Lauters] decided that he could build his own for the same cost while integrating a specific alert feature: one that fires off an SMS to predefined contacts upon mains power failure.

The first step was to enable communication between an Arduino Micro and a Nokia cell phone. His Nokia 3310 uses FBus protocol, but [Lauters] couldn’t find an Arduino library to make the job easier. Instead, he prototyped basic communication by running an Arduino Uno as a simple serial repeater to issue commands from the computer directly to the phone, and eventually worked out how to send an SMS from the ‘duino. [Lauters] then took the phone apart and tapped into the power button to control on/off states. He also disconnected the phone’s battery and plugged it into an attached PCB. The system operates off mains power but swaps to a 1000mAH 9V backup battery during a power outage, logging the time and sending out the SMS alerts. A second message informs the contacts when power has been restored.

Head over to [Lauters’s] project blog for schematics and photos, then see his GitHub for the source code. If you want to see other SMS hacking projects, check out the similar build that keeps a remote-location cabin warm, or the portable power strip activated by SMS.

Illegal, yet impressive

cans

Want a soda? Just grab a robot, shove it in a vending machine, and grab yourself one. This video is incredibly French, but it looks like we’ve got a custom-built robot made out of old printers and other miscellaneous motors and gears here. It’s actually pretty impressive when you consider 16 ounce cans weigh a pound.

UNOBTANIUM

chip

Okay, we got a lot of emails on our tip line for this one. It’s a group buy for a programmable oscillator over on Tindie. Why is this cool? Well, this chip (an SI570) is used in a lot of software defined radio designs. Also, it’s incredibly hard to come by if you’re not ordering thousands of these at a time. Here’s a datasheet, now show us some builds with this oscillator.

Chiptune/keygen music anywhere

keygen

[Huan] has a co-loco’d Raspi and wanted a media server that is available anywhere, on any device. What he came up with is a service that streams chiptune music from your favorite keygens. You can access it with Chrome (no, we’re not linking directly to a Raspberry Pi), and it’s extremely efficient – his RAM usage didn’t increase a bit.

Take it on an airplane. Or mail it.

bomb

[Alex]’s hackerspace just had a series of lightning talks, where people with 45-minute long presentations try to condense their talk into 10 minutes. Of course the hackerspace needed some way to keep everything on schedule. A simple countdown timer was too boring, so they went with a fake, Hollywood-style bomb. No, it doesn’t explode, but it still looks really, really fake. That’s a good thing.

Printers have speakers now?

nokia

[ddrboxman] thought his reprap needed a nice ‘print finished’ notification. After adding a piezo to his electronics board, he whipped up a firmware hack that plays those old Nokia ringtones. The ringtones play over Gcode, so it’s possible to have audible warnings and notifications. Now if it could only play Snake.

Classic Game Of Snake On An ARM Controller

September 21, 2012 by 4 Comments

Every now and again we take a break from looking at all of your awesome projects and get to work on our own. I thought I’d take a minute to show off my game of Snake. It’s a classic that I remember playing on a graphing calculator (TI-83) back in high school. I had never written my own version and decided it would be a good reason to spend some more time on the ARM platform.

The dev board I’m using is the STM32 F0 Discovery board. Once I had a usable template for compiling the code on a Linux box everything else just started to fall into place. The screen is from a Nokia 3595. Several years back I cut off the keypad and made a breakout board for it. It’s pretty dim but it’s small and uses SPI so it tends to be my go-to display for prototyping. But I did get my hands on an SSD1289 TFT screen (after writing about this project) for about $16 and I’ve had some success with that. It uses a parallel interface so it’s not as easy to hook up and I’ve had some crosstalk issues when running at 24 MHz.

But I digress. Check out the demo video of my simple game after the break. There are more details about my programming choices at post link above. You will see this hardware again soon. I’m working on an On Chip Debugging primer and these ARM dev boards are perfect for it!
