Today the Nokia brand can be found on a range of well-screwed-together Androind phones and a few feature phones, but as older readers will remember that before their descent into corporate chaos and the Windows Phone wilderness, there was once a time when the Finnish manufacturer dominated the mobile phone landscape and produced some of the most innovative and creative handset designs ever created. It’s for some of these that [Michael Fitzmayer] has done some work providing tools revive the devices from an unfortunate bricking.
The N-Gage was the phone giant’s attempt to produce a handset that doubled as a handheld game console, and though it was a commercial failure at the time it has retained a following among enthusiasts. The flaw comes as its Symbian operating system fills its user partition, at which point the infamous “White Screen Of Death” occurs as the device can no longer reboot. Rewriting the flash chip used to be handled by Nokia service tools, but these can no longer be found. His fix substitutes a “Blue pill” STMF103-based dev board that connects to the Nokia FBus serial port and does its job. It’s possible that it could be used on other Symbian devices, but for now it’s only been tested on the N-Gages.
It’s easy to forget when a smartphone is defined by iOS and Android, that Symbian gave us a smartphone experience for the previous decade. For those of us who still pine for their miniaturised Carl Zeiss Tessar cameras and candybar form factors, it’s good to see them receiving some love.
After a couple of months away we’re returning with our periodic roundup of happenings in orbit, as we tear you away from Star Trek: Discovery and The Mandalorian, and bring you up to date with some highlights from the real world of space. We’ve got a launch to look forward to this week, as well as a significant anniversary.
With mobile phones now ubiquitous for the masses in much of the world for over two decades, something a lot of readers will be familiar with is a drawer full of their past devices. Alongside the older smartphone you’ll have a couple of feature phones, and probably at the bottom a Nokia candybar or a Motorola flip phone. There have been various attempts over the years to make use of the computing power the more recent ones contain through using their smartphone operating systems, but the older devices remain relatively useless.
[Vishwasnavada] has a neat plan though, using an ancient phone as a remote trigger device, by interfacing it with an Arduino. There are many ways this could be achieved depending on the model of the phone in question, but one thing common to nearly all devices is a vibration motor. Removing the motor and taking its power line to a GPIO allows the Arduino to sense when the phone is ringing. The idea then is that a call can be placed to the phone which is not picked up, but because it triggers the vibration motor it can be used to make the microcontroller do something remotely. A hack with limited capabilities then, but one that is cheap and simple, uses a recycled device, and should work almost anywhere populated on the planet given the global reach of 2G networks.
The Nokia 3210 is the greatest cell phone ever made. The battery lasted for days, custom color covers were available at every mall kiosk, it had the Snake game, and the chassis for this phone was finely crafted out of the crust of neutron stars. It was indestructible; it is the reason we now appreciate technology over more impermanent concepts like relationships and love.
For his Hackaday Prize entry, [Bastian] is bringing the Nokia 3210 into this century. He’s designing a circuit board with the same footprint, the same button layout, and a better screen that drops right into the lovely plastic enclosure of the 3210.
The current BOM for the upgraded 3210 includes an STM32 F7 microcontroller, which is more or less the current top of the line ARM micro you can get. For wireless, [Bastian] is using an A7 GSM/GPRS module and an ESP8266 for a little bit of WiFi. For a dumbphone, this is ludicrously overpowered. Provided [Bastian] gets a prototype up and running, there will be some interesting applications for a device this powerful in a package this indestructible.
One of the things [Bastian] has been butting his head against with this project is KiCad. Microvias don’t work like they should in KiCad — they’re restricted to the outer layers only. This is a problem for routing a complex board like this, so [Bastian] wrote a patch that gives KiCad an ‘I know what I’m doing mode’ for microvias everywhere.
This is truly the spirit of The Hackaday Prize: not only is [Bastian] building something ridiculous, he’s also creating the tools to do it.
Old hardware you may have on hand cannot only inspire projects in their own right, but can facilitate the realization of any ideas you have been planning. Using a Nokia N900, [MakerMan] concocted a light-up sign with a live subscriber and view count of his videos.
[MakerMan] milled out the logo used on the sign with his DIY CNC machine — built from rotary bearings and recycled stepper motors off industrial Xerox printers. The meticulous application of a jigsaw, rotary tool, and grinder resulted in a sturdy frame for the sign while a few strips of RGB LEDs imbue it with an inspiring glow. All that was left was to mount the phone in place and tape it for good measure.
[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.
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.
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.
