Air Conditioner Speaks Serial, Just Like Everything Else
http://hackaday.com/2017/01/06/air-conditioner-speaks-serial-just-like-everything-else/
Like so many other home appliances, it’s likely that even your air conditioner has a serial interface buried inside it. If you’re wondering why, it’s because virtually every microcontroller on the planet has a UART built in, and it’s highly useful for debugging during the development process, so it makes sense to use it. Thus, it was only a matter of time before we saw a hacked airconditioner controlled by a Raspberry Pi.
Hacking a Mitsubishi Heat Pump / Air Conditioner
https://nicegear.co.nz/blog/hacking-a-mitsubishi-heat-pump-air-conditioner/
Quite a few years back I decided that I wanted to hack my heat pump. The infrared remote control was boring, who wants to press buttons. I thought about automatically generating the infrared remote button protocol like a few others have done before but that still doesn’t tell me what the heat pump is doing. Did it actually turn on after you sent those commands? I thought I could do better, so I decided to pull apart my newly installed heat pump unit and start poking around in there with a meter to see what happened.
we need to connect to communicate with the unit from the outside world – thoughtfully of them they made us a serial port to talk to, it’s 5V TTL UART running at 2400 bps and even parity. A little weird, I discovered that with a Saleae Logic Analyser – a very handy little hacking tool.

Raspberry Pi Zero FPV camera and OSD
https://hackaday.io/project/12450-raspberry-pi-zero-fpv-camera-and-osd
Pi Zero and camera weigh 13 grams making it an ideal setup for data logging, HD video recording and custom On Screen Display for FPV.
Description
This is a low cost FPV and OSD system capable of recording HD video. It is built with Raspberry Pi Zero, PiCamera, GPS sensor and FPV transmitter.
Pi Zero is consuming about 0.2 A while recording 1080P video.
WiFi is not really suitable for real time video streaming unless you have powerful CPUs and strong connection. This fact alone makes it very hard to use Pi Zero and WiFi to get steady video stream over large distances. Perhaps there is another way?
It is not widely known, but all Raspberry Pis have analog TV output on board (in addition to HDMI), even Pi Zero sports one! You can use that analog TV output to stream a video feed from the Pi Zero to a screen far far away via a hobby grade FPV transmitter.

For anyone wanting to get that shot of nostalgia without the hassle of finding an NES Classic, the Retropie project is a great starting point. Of course, it’s not too noteworthy to grab a Raspberry Pi, throw a pre-built distribution on it, and plug in an SNES to USB converter. What is noteworthy, however, is building a Retropie that’s portable and that has the quality and polish of the latest build from [fancymenofcornwood].

A Simple Route To A Plug Top Pi

There are a host of tiny plug-top computers available for the experimenter who requires an all-in-one mains-powered computing platform without the annoyance of a full-sized PC or similar. But among the various models there has always been something missing, a plug-top Raspberry Pi. To address that gap in the market, [N-O-D-E] has created a fusion of Pi and plug using the official Raspberry Pi PSU accessory and a Raspberry Pi Zero, with a UUGear Zero4U USB hub sandwiched between the two.

A project log for ZeroPhone – a Raspberry Pi smartphone
Pi-powered open-source mobile phone (that you can assemble for 50$ in parts)
https://hackaday.io/project/19035-zerophone-a-raspberry-pi-smartphone/log/51839-project-description-and-frequently-asked-questions
What is this?
This is a smartphone, with a Raspberry Pi Zero at its heart. It’s open-source*, Linux-powered and you can make one yourself for 50$!
*except some parts, replacing which would make it crazy expensive
Why?
Because it has so many uses, the idea sems to be obvious and yet there isn’t a project like that. Moreover, I’ve been studying the topic for a couple of years now and this project is meant to be useful to other people as well – so I have a chance of commercializing it (while still keeping it open-source).
What OS is used?
It uses Raspbian Linux, which is currently based on Debian Jessie. This is because it can be tailored to suit our purpose very easily, and will still be /upgradable in the future – this project doesn’t need a separate distribution since that’s prone to obsolescence and is a maintenance nightmare (but I do plan on providing ready-to-go SD card images if the demand is there).

ZeroPhone gives Smartphones the Raspberry (Pi)
http://hackaday.com/2017/01/18/zerophone-gives-smartphones-the-raspberry-pi/
There are several open source phones out there these days, but all of them have a downside. Hard to obtain parts, hard to solder, or difficult programming systems abound. [Arsenijs] is looking to change all that with ZeroPhone. ZeroPhone is based upon the popular Raspberry Pi Zero. The $5 price tag of the CPU module means that you can build this entire phone for around $50 USD.
The radio module in the ZeroPhone is the well known SIM800L 2G module.
An ESP8266 serves as the WiFi module with an OLED screen and code in python round out this phone.

Programming Thousands of AVRs
http://hackaday.com/2017/01/18/programming-thousands-of-avrs/
It is funny how almost everything has its own set of problems. Rich people complain about taxes. Famous people complain about their lack of privacy. It probably won’t happen us, but some Kickstarter campaigners find they are too successful and have to scale up production, fast. We’d love to have any of those problems.
[Limpkin] found himself in just that situation. He had to program several thousand Atmel chips. It is true that you can get them programmed by major distributors, but in this case, he wanted unique serial numbers, cryptographic keys, and other per-chip data programmed in. So he decided to build his own mass programming workbench.
The bench programs nine devices at a time (due to the number of I/O available) and uses a Raspberry Pi to orchestrate operation.

This post is a about vision enhancement platform called The All-Seeing Pi that I have been working on with my friend Dan, who is blind. People who are blind rarely have no vision at all though, and in Dan’s case, he still has a little bit of sight in one eye. He’s also the first to tell you how much technology can do to enable mobility.
From these discussions, we came up with the idea for a video feed connected to a display, with a wearable screen in the ideal spot for maximum vision. This allows someone to focus on just the screen, and let the camera capture the detail and depth of the environment.
In the end, the prototype served as a successful proof of concept.

Flash ROMs with a Raspberry Pi
http://www.linuxjournal.com/content/flash-roms-raspberry-pi
To hardware-flash a BIOS chip, you need two main pieces of hardware: a Raspberry Pi and the appropriate Pomona clip for your chip. The Pomona clip actually clips over the top of your chip and has little teeth that make connections with each of the chip’s pins. You then can wire up the other end of the clip to your hardware-flashing device, and it allows you to reprogram the chip without having to remove it. In my case, my BIOS chip had 16 pins (although some X200s use 8-pin BIOS chips), so I ordered a 16-pin Pomona clip on-line at almost the same price as a Raspberry Pi!
There is actually a really good guide on-line for flashing a number of different ThinkPads using a Raspberry Pi and the NOOBS distribution
There are two main ways to build flashrom. If you intend to build and flash a Libreboot image from source, you can use the version of flashrom that comes with the Libreboot source. You also can just build flashrom directly from its git repository.
To wire everything up, I opened up my X200 (unplugged and with the battery removed, of course), found the BIOS chip (it is right under the front wrist rest) and attached the clip. If you attach the clip while the Raspberry Pi is still on, note that it will reboot. It’s better to make all of the connections while everything is turned off.
Then I booted the Raspberry Pi, loaded the two SPI modules and was able to use flashrom to read off a copy of my existing BIOS
After you have a good backup copy of your existing BIOS, you can attempt a flash. It turns out that quite a bit has changed with the Libreboot-flashing process

PiSound, The Audio Card For The Raspberry Pi
http://hackaday.com/2017/03/16/pisound-the-audio-card-for-the-raspberry-pi/
Kids today are being loud with their ‘drum machines’ and ‘EDM’. Throw some Raspberry Pis at them, and there’s a need for a low-latency sound card with MIDI and all the other accouterments of the modern, Skrillex-haired rocker. That’s where PiSound comes in.
Of course, the Pi already comes with audio out, but that’s not enough if you want to do some real audio processing. You need audio in as well, and while you’re messing around with that, adding some high-quality opamps, ADCs, DACs, and some MIDI would be a good idea. This is what the PiSound is all about.

Cigar Box Opens to Raspberry Pi Laptop
http://hackaday.com/2017/03/21/cigar-box-opens-to-raspberry-pi-laptop/
If you were to go back to the middle years of the twentieth century and talk to electronic constructors, you would find a significant number had a cigar box radio among their projects. Cigar boxes were fairly robust, readily available, and could easily accommodate the parts required to make a crystal set or a simple one-tube regenerative receiver.
Cigar boxes, however, remain. [Mike] found a very nice antique cigar box, and made something unexpected, he put a Raspberry Pi in it and made something close to a laptop. Into the lid goes an LCD screen secured with wooden blocks, while in the body of the box goes the LCD controller, Pi 3, and battery charger and PSU modules. There are two sets of cells, one each for screen and Pi.

Bomb Defusal Fun With Friends!
http://hackaday.com/2017/03/21/bomb-defusal-fun-with-friends/
Being a member of the bomb squad would be pretty high up when it comes to ranking stressful occupations. It also makes for great fun with friends. Keep Talking and Nobody Explodes is a two-player video game where one player attempts to defuse a bomb based on instructions from someone on the other end of a phone. [hephaisto] found the game great fun, but thought it could really benefit from some actual hardware. They set about building a real-life bomb defusal game named BUMM.
The “bomb” itself consists of a Raspberry Pi brain that communicates with a series of modules over a serial bus. The modules consist of a timer, a serial number display, and two “riddle” boxes covered in switches and LEDs.

3G to WiFi Bridge Brings the Internet
http://hackaday.com/2017/03/28/3g-to-wifi-bridge-brings-the-internet/
[Afonso]’s 77-year-old grandmother lives in a pretty remote location, with only AM/FM radio reception and an occasionally failing landline connecting her to the rest of the world. The nearest 3G cell tower is seven kilometers away and unreachable with a cell phone. But [Afonso] was determined to get her up and running with video chats to distant relatives. The solution to hook granny into the global hive mind? Build a custom antenna to reach the tower and bridge it over to local WiFi using a Raspberry Pi.

Looking for something a bit more from your Raspberry Pi? Tired of the usual console and arcade games? Eltech’s Exagear Desktop is a virtual machine that runs on your Raspberry Pi and allows you to run x86 games. [Dmitry]’s done a write-up about running more modern games on your Raspberry Pi.
Up until now, the Pi has been a great platform for retro gaming. By running MAME or EmulationStation, you can play classic arcade games as well as the great console games you played as a kid. Exagear Desktop goes one further, allowing you to use Wine to play more modern PC games on your Raspberry Pi 3.
