NotesThis is a replacement PCB for the Magicforce 68 keyboard. It is powered by a cheap Pro Micro controller. This is the second version, more information can be read in this post and details on github.FeedUnfurl
NotesPortable Raspberry Pi enabled gaming system projects seem to be everywhere. The concept is relatively simple; get an old GameBoy (or other old portable) shell, stuff in a Raspberry Pi Zero as well as some switches, LiPo battery and charger, an LCD screen, and maybe an audio amplifier and youâre set (except for the giant mess of wires.)FeedEmbedUnfurl
NotesAmong the clones manufactured by the Communists was the Cobra or CoBra. The name stands for COmputere BRAsov, with Brasov being the town in central Romania where these machines were assembled to be used by enterprises. Of course, ordinary people couldnât buy themâwhich is what first led several students at the Politehnica University of Bucharest deciding to build them themselves.Unfurl
NotesA Harmonograph is 19th-century mechanical device which draws geometric patterns based on the motion of pendulums. (For a real example, see Marie-therese's Maker Faire project - A 3-pendulum Harmonograph. Also, search youtube for videos like this one) By adjusting the physical parameters of the device, and initial conditions of the pendulums, you can vary the patterns it can make.Unfurl
NotesPockulusC.H.I.P. started as a joke. But then we actually got it working. Thatâs right, the most affordable standalone virtual reality headset in the world started as a joke and it works!Unfurl
Notesthis project aims to build, test, and mass produce a Teensy/Arduino USB Keyboard controller, for use as a drop in replacement into any IBM Buckling Spring keyboard.Unfurl
NotesReminiscent of Project Ara, Googleâs much hyped but continually delayed effort to build a âhardware ecosystemâ around smart phones, the RePhone is a modular phone built from open source components.FeedEmbedUnfurl
Notesthese days you won't find anything that outputs s-video via two RCA cables. I've seen people make adapters from the standard 4 pin s-video plug to 2 RCA connectors, but I think I have a better solution.Unfurl
NotesWhat happens is that the contacts on the harness loosen over the years. The connectors also oxidize and start making bad connection with the board. As the resistance to the current goes up, so does the heat which burns up the connector.Unfurl
Notes2014 brought us plenty of new open-spec, community-backed SBCs â from $35 bargains, to octa-core powerhouses â and all with Linux or Android support.FeedEmbedUnfurl
Notes Celebrate the 25th anniversary of that classic gaming device by building your own with 3d printing and DIY electronics from adafruit. In this project we'll use a raspberry pi and TFT touch screen to make an epic DIY gamegirl. FeedUnfurl
NotesThe RB912UAG-2HPnD is a very versatile device. It is a small wireless router with an integrated 2.4GHz high power wireless card and an additional miniPCIe slot for 802.11 wireless, or 3G card. The Gigabit port helps to utilize the full potential of 802.11n wireless speeds. Unfurl
NotesSince the Raspberry Pi was just sitting there, and the Amiga lacked (*) a network adapter - why not just connect the dots and get something up and running? I did, and it worked. Here's a quick writeup on what I did - if anyone's interested I can write a more detailed post with all the information I have.Unfurl
NotesThis guide talks about how we selected LCD screens for the Raspberry Pi media panels we are building. A media panel is a new and different class of computing appliance.Unfurl
NotesNovena is the codename for an open computing platform. It is a work in progress, but nearing a point where we think it could be viable for public release. FeedUnfurl
NotesAn Arduino, with its 8-bit 16 MHz microcontroller, will set you back around $20. A microSD card with several gigabytes of memory and a microcontroller with several times the performance could be purchased for a fraction of the price.FeedEmbedUnfurl
NotesIf youâre a web developer and youâre looking at playing with hardware, donât shy away from the electronics. There are no magic bits of hardware that will give you full control of the physical world in a box â though there are plenty of attempts at this. Develop your knowledge the same way you do with the web â by reading, tinkering, playing with code and breaking stuff. Go join a hackerspace, get some learning materials, visit electronics shops, pull things apart and learn how they work.Unfurl

NotesI have decided to publish some of my âarchaeologicalâ work from last year on Cy Endfieldâs MicroWriter. The original objective was to produce a cycle-accurate emulator. I do not currently have the free time to complete this project, so I will post my results here for anyone who might care to pick up the torch. Click on some of the images to see the full-resolution version.FeedUnfurl
NotesStay away from super-cheap AC adapters built by mystery manufacturers. Spend the extra few dollars to get a brand-name AC adapter. It will be safer, produce less interference, and your device's touchscreen will perform better. FeedUnfurl
NotesThe three models (all of which we use here at Digital Diner) are the Arduino, Raspberry Pi and BeagleBone. We chose these three because they are all readily available, affordable, about the same size (just larger than 2âł x 3âł) and can all be used for creating wonderful digital gadgets. Before we get to the comparison, here is a brief introduction to each one.FeedEmbedUnfurl
NotesRecently, I paid $12 at Mingtong Digital Mall for a complete phone, featuring quad-band GSM, Bluetooth, MP3 playback, and an OLED display plus keypad for the UI. Simple, but functional; nothing compared to a smartphone, but useful if youâre going out and worried about getting your primary phone wet or stolen. FeedEmbedUnfurl
NotesHereâs the tl;dr version. The MacBook Air 128 gives you 77.3 percent of the advertised storage space for user data. The Surface Pro 128 gives you 75.2 percent of its advertised capacity for storing data. And with one minor tweak that doesnât affect the systemâs capabilities in any way, you can increase the amount of data storage space on the Surface Pro to 81.8% of the advertised capacity.FeedUnfurl
NotesI have an ex-grilfriend who's little brother would literally lick the contacts on his N64 carts. That's right, not a gentle 'phwwwww', but a full-on French kiss.FeedUnfurl
NotesHDMI-CEC is a device control protocol that runs over HDMI cables.
It allows rudimentary control over HDMI-CEC aware devices - these devices oftern have vendor-specific names for the protocol, such as AnyNet+ for Samsung devices. FeedUnfurl
NotesAll modern TVs support HDMI-CEC a technology that allows devices to talk with each other over the HDMI cable, using this feature this adapter will send and receive remote key presses to XBMC or MythTV or Windows Media Centre or any other app that supports libCEC on your PCUnfurl
Notes The Defense Advanced Research Projects Agency (DARPA)'s Cyber Fast Track program helped funded the development of the Power Pwn. Pwnie Express, which developed the $1,295 gizmo, says it's "a fully-integrated enterprise-class penetration testing platform." That's great, but the company also notes its "ingenious form-factor" (again, look at the above picture) and "highly-integrated/modular hardware design," which to me translates to: it's the perfect tool for hacking a corporate network.
