I’ve just uploaded the latest code to code.google.com. It is still incomplete, and I’ve discovered several annoyances with the thing: You must send a broadcast message to locate the eframes; you can’t simply connect directly to the frame’s IP. If you don’t then the frame doesn’t receive its FTP port properly after a total powerContinue reading “bt eframe progress”

Here’s what I recorded the previous post with: So that consists of: Middle: 80Gb Ipod Left: Belkin TuneTalk stereo ipod recording addon thing Bottom: Mic preamp Top left: binaural headset I bought Top right: binaural headset I made (old earbuds + 2 electret microphones) Middle: Headphone restraint. The binaural headset I made actually works justContinue reading “Binaural rig”

Ladies and gentlemen, experience the thrills of three minutes of the way home (4Mb mp3) in full binaural surround sound. Warning: may not actually be very interesting, as I’m only just getting going again 🙂 Oh, and listen with headphones.

I held off on the firmware dumping for a day or so and concentrated on the network protocol. I’ve implemented the protocol basics in python and can now search for frames, and read the storage and system statuses. I’ve just created an "adqmisc" google code project to keep miscellaneous small projects in, so the current sourceContinue reading “BT Eframe 1000 progress”

I hate seeing things like this on boards: Its obviously got pads for DIP switches of some sort, but its mysteriously unpopulated! Luckily, searching for “Innolux” and “CPT” reveals they’re competing LCD display manufacturers. So this must be for configuring the type of LCD that is connected. This makes me think that BT have justContinue reading “Mysterious pads identified”

Just received my BT eframe 1000 this afternoon; set it up in the office to play with a bit 🙂 Anyway, first order of work when I got home was to open the thing and have a look. This guy has already done this, but it wasn’t thorough enough for my purposes unfortunately. (the chipContinue reading “BT eFrame 1000”

Finally got round to updating the style on my journal; I think it looks much cleaner now. I also enabled non-LJ-user comments etc. More documentation added to pypickit, including some nice diagrams: I’m having to wait before I can make any progress though; I managed to fry the power MOSFET on the pickit when IContinue reading “Style update”

I’ve just created a project on google code so my python pickit code is in a public place for others to use. Currently it supports the Microchip PicKit2 ICD device, and has libraries for talking to Cambridge Silicon Radio Bluetooth devices, Elantech EKT8210 touchpads, and SPI flashes. The wiki is not completed yet; I’ll fillContinue reading “pypickit”

First order of work is to interface onto the BT module for reprogramming purposes. Its an SPI device, and you’re meant to use an expensive development kit to program it. However, I don’t see why that should be the case when I’ve already got an SPI interface on my pickit. All I have to doContinue reading “Bzzzz XBees arrived”

After recovering earlier today, I’ve been reading up on these XBee RF Modules. Effectively you can hook two of them up and get a point to point wireless serial link between them at a fairly reasonable distance. They also support some form of mesh networking, so I assume you could have loads of them scatteredContinue reading “XBee wireless point to point link project ideas…”
