My week-end with E.V.E
I spent part of my week-end finishing the voice recognition sub-system, tweaking E.V.E’s UX and cleaning up E.V.E / A.D.A.M code. Let’s see how it went ! E.V.E loves snakes E.V.E’s interface is based on HTML5/Javascript and runs inside a browser. I wasn’t too happy with my RPi’s browsers until I settled for Epiphany. Even[…]
E.V.E is witty
Yesterday, I tested a tiny USB microphone for E.V.E, and managed to recognized the recorded sentence with the help of the wit.ai platform (even though the quality of the microphone was a little poor). Let’s get a little deeper into wit.ai and see how it could be helpful for E.V.E. Trying another USB Microphone I[…]
E.V.E is all ears
Now that enough progress has been made on E.V.E touch-enabled interface, and since we added a websocket-enabled general purpose middleware (A.D.A.M) to handle local hardware and proxy HTTP requests, we can now tackle voice recognition. The audio sub-system The audio sub-system is probably the weakest point of Raspberry Pi. Without extension (such an USB audio sub-system), only two audio[…]
E.V.E meets A.D.A.M
In the previous post, we quickly reverse-engineered an Orange LiveBox Play set-top box and how it can be easily driven by simple HTTP requests. Be before implementing an interface between E.V.E and this kind of set-top box, we need to sit down and think a bit. Indeed, for now, E.V.E is nothing but a web[…]
E.V.E sips Orange juice
Since I’m still waiting for all the audio components I ordered for E.V.E’s voice recognition functionality, let’s try in the meantime to interface E.V.E with a first home device. The very first one that comes to my mind is of course a television set. Let’s try ! Reverse-engineering an Orange Livebox Play set-top box I rely on[…]
E.V.E is a Yodeling Cowgirl
Here is a little followup of this week-end work on E.V.E. I’m still at a prototyping stage which means there rough edges and that the source code is sometimes naughty), but it’s getting long nicely. E.V.E is now a Yodeling Cowgirl During this week-end tests, I tried to complete the simple internet radio functionalities of the[…]
A kiosk mode for E.V.E
E.V.E front panel is touch-based. This is why I ordered an official touchscreen for Raspberry Pi, that I started to play with last night. The software on E.V.E’s front has to run in kiosk mode. There are many alternatives. On could be to use a dedicated framework like Kivy, which can handle multi-touch and be[…]
E.V.E has a sens of touch
Since our previous post, the touchscreen and the stand I ordered at Swag shop were delivered (this morning actually). It is now time for an unboxing and a first setup ! The unboxing Two packages were sent via Chronopost: A first one – a very sober white box with no label – containing the 7″ touchscreen[…]
Say hello to E.V.E
It’s been (yet again) a very very long time since I posted news on “Jarvis”, my pet project on Raspberry Pi. So long I would consider Jarvis project to be almost dead (although it spawned a project internally used at work, but re-baptized “Moshi-Moshi“). Nevertheless, home automation, voice recognition, new forms of human-machine interactions, and[…]

On hidden realities (part 1)
Since I took a 4 weeks vacation, and I’m getting really bored, it gave me time to push a (muuuuch) needed upgrade to this blog and to publish a couple of posts. I wanted to publish a few posts on multiverse for a long time. I stole the title of this series of post, “On[…]
Server crash, and moving to a new hoster
After 6 long years, my good old Shuttle server died a week ago 🙁 Even if both the power unit and the CPU burned (!), there were absolutely no data dammage. This little fellow used to run web sites, home-automation services and share internet connections between all my devices. I tried to replace my Shuttle[…]
Project “Jarvis”: step five (look at me)
Tonight, I’ll go for a very simple hack: connect a webcam, detect motions and stream a live feed over HTTP. Not sure how it’ll fit with Project “Jarvis”, but who knows … Hardware First things first: the hardware. For some reasons, the only webcam that I had was an old Apple iSight. You know, the[…]
Project “Jarvis”: step four (GUI)
Here comes another step in the conception on project “Jarvis”. For once, let’s not be too geeky. I feel artsy today. I’ll focus on the GUI and fire up Inskcape et the Gimp. Yeah, still a bit geeky, I know… Jarvis-like GUI Let’s try the first idea take comes to my mind: create an[…]
Project “Jarvis”: step three (the brain)
During the last steps, voice recording, speech-to-text and text-to-speech feasibility was studied. Now enters another difficicult part: the brain ! The last steps implied the use of external services for voice-recognition and text-to-speech capabilities. When it comes to Jarvis’ brain, the idea is twofold: Onboard answer engine: part of the analysis will be done onboard[…]
Project “Jarvis”: step two (speak to me)
In my previous post, I conducted a few experiments with speech recognition via Google’s Speech API and get enough results to push the project “Jarvis” a bit further. Now it is time for Jarvis to speak ! Text-To-Speech engines There are many “Text-To-Speech” engines already packaged for the Rasberry Pi. Namely: espeak: eSpeak is[…]
Project “Jarvis”: step one (proof of concept)
Adding Siri to both my old iPad 1 and iPhone 4 was a failure 🙁 Jailbreaking went nice, but messing up with SiriPort was a complete disaster, and it took me nearly 2 hours to turn back these devices into something different than a brick. And thus … no SiriProxy for me. But then[…]
Raspberry Pi, ready to serve !
Alright. My Raspberry Pi by is set up and delivering AirPrint and AirPlay services. Let’s add few web capabilities. A lightweight configuration: Nginx & SQLite I felt like the usual Apache / MySQL duet might be a little to heavy for my tiny ApplePie. So, I opted for a Nginx / SQLite couple. Everything[…]
Baking Apple Pies
Now that “applepie” (my very first Raspberry Pi) is set up, it is time to have a little fun. The first hacks will be to turn the device into a cheap (but nonetheless quite efficient) AirPlay / AirPrint device, while baking a real Apple Pie… Setting up AirPlay First, I hooked up the Raspberry Pi[…]
A healthy dose of raspberries
It’s been two long weeks, but the Rasberry Pi I ordered finally arrived this friday. I’m extremely excited with this tiny thing. Just like messing with my first computer (30 years ago…) or patching a Linux kernel for the first time. Yep, I really do feel like a kid 🙂 Raspberry Pi The Raspberry[…]
What’s been cooking ?
I haven’t been posting anything about cooking for a long time. Since I have made (some) progress and I’m getting a little better at taking picture, here’s a little catch up (pun intended). Let’s start with a few french classics: .. then, a few italian cuisine: … Asian food: A bit[…]
What’s this Higgs boson anyway ?
Recently, there’s been a lot of talk about the Higgs boson. A month ago, both teams from CMS and ATLAS experiments at LHC have announced independently the discovery of a previously unknown boson of mass between 125–127 GeV/c2. The characteristics of this new particle are consistent whith the ones of the Higgs Boson. Without getting[…]
HDD meltdown …
The last couple of days have been terribly hot here, reaching 41°C yesterday. Alas, it was way too hot for my home server hard drive, which was already in a baaaad shape. Of course, it died while I was in the process of a much needed system upgrade (in the spirit of this other upgrade).[…]
What to do the first days of once summer holidays ?
Nope, watching the Olympic Games wasn’t an option. Time to upgrade this old blog to a decent version of wordpress. It was about time… Migrating to the latest version of wordpress (from such an obsolete one) wasn’t exactly a piece of cake. I had, of course, to migrate the theme, but also rewrite a few[…]
Upgrading quantum-bits
Once again, it’s been a long time since the last post. Partly because I’m overworked, partly because my good old blog became technically obsolete and is now plagued by security vulnerabilities. Some *ucking morons have been exploiting these holes in order to send spam, which pissed me off quite a bit (and almost got me[…]
Bad luck :(
After years of loyal service, my home server HDD is given evident signs of aging, which include some data loss. And guess what ? Yes, both redundant hard disks on which I’m backuping this server are also giving signs of failure… Now, that’s what I call bad luck 🙁 I’m crossing my fingers while trying[…]
Star wars: a new home
Ok, the title of this post is very silly. Anyways, as I mentioned before, I moved a couple of months ago to a new apartment, right in the center of Lyon, France. Some have asked for a few pictures. Here goes, although it is not yet fully furnished. These are pictures of a new[…]
Which geek am I ?
Let’s start this new year with a fundamental question: what kind of a nerd am I ? As some may know, I’m a huge fan on “The Big Bang Theory” TV series. How could it be otherwise ? Geeks, physicists, addiction to comics and a cute neighbor. The perfect cocktail. Yep, I’m the kind of[…]
And … we’re baaack !
Alright, my server’s been up again since a few days. It took much longer than I thought, “thanks” to Orange which messed up for two long long weeks with my phone line… That said, it showed how difficult it was for me to live without Internet connectivity. Not a very good sign, I guess :-/[…]
Sorry, we’re closing (for a short time)
Good news: I found a new apartment (VERY excited about that). Bad news: since I’ll be moving my server, there will be some downtime within the next weeks. Hopefully, It’ll will be short. Next posts will be written from my new apartment 😀
Silence, ça pousse…
So, I did a little gardening this summer for my parents, while they were on holidays for a few weeks. Every other day, I managed to fill a full basket of fresh veggies: tomatoes, eggplants, cucumbers, … Cool ! So, I treated myself with a few (mostly) veggie-based meals. Their garden produced quite a[…]
Will I ever be a grown-up ? (part 2)
The only difference between a kid and an adult is the price of the toys. Of course, I got myself a brand new iPad and I’ve been playing with it for a couple of days now. Yep, I think I’m turning into a freaking Apple fanboy… This baby is sleek and fast. Of[…]
Digital Media Server, DLNA and Samsung
My new LED TV and Blu-Ray player are DLNA compatible. Since the Blu-Ray player came with wifi connectivity out of the box, I tried to connect it with my GNU/Linux Home Server. In the end, it worked well, but the process wasn’t as easy as I expected… My main devices are interconnected (more or[…]
Will I ever be a grown-up ?
Hopefully, never. I’ve finally received my brand new toys: a Samsung 55” LED TV along with a Blu-Ray player (Samsung as well). Yes, it’s a 3D player, and, well, 3D movies generally suck. But for some reasons, it was cheaper and it came with wifi connectivity out of the box, so it was easy choice.[…]
Basic principles of General Relativity
As promised a couple of posts ago, here are a few words on General Relativity. I’ll try to concentrate on the principles by not focusing (too much) on technicalities. Keeping this post concise is quite a challenge, because of the incredible beauty lying in the physics and mathematics of General Relativity. A thing of beauty[…]
30 years of computers, gadgets and technologies
While doing a little housekeeping, I dug out a pile of old magazines I preciously kept for many years. I used to read Hebdogiciel (an old french computer magazine) when I was a 13 to learn and share programming techniques. So much memories. Thinking of all the events, amazing gadgets and people I had[…]
