API Transaction Pulling Starts Today

Filed under: EVE-Central, Software — Yann @ 10:50 pm

As you may (or may not) have noticed, the User Settings page on EVE-Cental.com now contains an option to set your full API key. Note that it requires the full API key in order to pull your market transaction logs. I am posting this announcement now as I’d like to collect as many API keys as possible in order to help test the system. If you’re willing to help, please log in to EVE-Central.com and set your API key.

The log data will not currently show up in any online view. I am working on polishing the framework for matching them to existing orders, and other similar fun.

I also have not published the full terms of use for the API logs. The market transaction logs available from the service will however never contain identifying information, such as your character name, IDs, etc. It will be a completely anonymous donation.

New tradefinder feature – per order volumes

Filed under: EVE-Central — Yann @ 10:28 pm

We’ve included per order volumes into the Sell to Buy tradefinder service. Now each order will have the accompanying volume displayed, after the units tradeable measurement. It is displayed as “Buy -> Sell”.

I am working on more new features, which are slowly getting pushed to the production system. Stay tuned.

Getting ready for Apocrypha

Filed under: EVE-Central — Yann @ 8:39 pm

I will be turning on my psuedo-manual new item import system for Apocrypha when it hits, to try to capture some of the new items as time progresses. While it may be a few days before the first T3 ships hit the market, I’ll be ready :)

If you have any bug reports or missing items reports, please e-mail them to me, comment on this blog, or plop them into Bugzilla.

Note that wormholes do not have markets, and aren’t “normal” travel routes, so won’t be covered in the EVE-Central database any time soon.

Thanks!

For those of you with a Mac (or Linux)

Filed under: EVE-Central, Software — Yann @ 3:53 pm

The source version of the EVE-Central uploader available from the main page has some issues working correctly on a Macintosh or Linux system do to bad path separators. Below is a link to grab a version of the uploader from the Git repository which contains a small patch to work around the issues. You’ll need an install of Python and wxPython (Unicode) appropriate for your system in order to use it.

EVE-Central uploader with Path fixes

Further up the Git tree is an unfinished UI refactoring effort (that is over a year old). If someone wants to take up the task of trying to complete the multiple-client uploader refactoring, they are more than welcome to.

Hardware Design: nRF24Z1 Wireless Digital Audio Streamer Super-Breakout Board

Filed under: Hardware, Software — Yann @ 2:35 pm

I’m pleased to announce a new hardware board in development. It isn’t available for sale right now, but prototype testing is under way, and is being double checked for any design problems.

It is a “super” breakout board centered around the Nordic Semiconductor nRF24Z1 Wireless Audio Streamer, a low-power self-contained 2.4GHz digital audio streaming chip. This little chip is capable of sending a 44.1KHz stereo digital signal, straight from a S/PDIF source, to another S/PDIF input, over a 2.4GHz wireless link, with minimal latency. If analog is more your thing, it also features a complete I2S interface (including clocking) which can drive an ADC or DAC (depending if its in transmit or receive mode). Perfect for your DIY projects with outside speakers, wireless headphones, and more.

On this breakout board, you will find:

  1. An Atmel ATtiny84 microcontroller, for command and control of the radio link, plus communication between the modules
  2. An Octal-Inverter and all of the needed S/PDIF circuitry to correctly use and drive the 1V digital signal
  3. A 20 pin breakout header which exposes most of the microcontroller and radio pins.
  4. An integrated, inverted-F PCB antenna with superior performance to “chip” antennas, while not hogging large amounts of PCB space
