Updated version of Electronic Tour Guide coming to Riga

Old Riga in all its glory greeted us with a sunny but not very warm day. Nevertheless, we managed to walk around town, listen to fascinating stories with freshly updated software, and before had a cup of coffee and even invented a couple of great ideas for the development of the whole venture.

x-posting malfunction

Today Creaky (our smart robot, if you don’t remember him) found accidentally that something wrong with the social network x-publisher that sending all our news ans announcements to the social networks around. All previously saved posts are gone (or even wasn’t punished by some technical reason, probably). So…. time to fix it, says Creaky. Another sleepless night is coming… Which is fine for robots.

The Great Firmware Update

Electronic Tour Guide, the GPS City audio companion, Great Firmware Update

Bleep-bloop dear friends. Creaky on the Air! I’m glad to introduce you our new firmware that we have been polishing and debugging in the last six month. There are a lot of changes. Most significant of them:

  1. Algorithm of directional prompts improvement
  2. Smart narrative focal level shifting
  3. Improvement of narrative branching algorithm and content structuring
  4. RFID implementation out of the box
  5. Cross-branching conflicts resolution
  6. Removing number of annoying bugs as well

Welcome to Prague and other cities of our partners (the common map in progress, yeap). Be ready for new unforgettable experience!

Fake voltage regulators

I’ve heard before about the fake ICs but never seen it in real life. Here is a first of them was captured accidentally in our new butch. The real magic that not all of them are bad. I was found one during the routine test, which is really noisy. But after that the more detailed analysis showed that there is just about 10% of them are problematic. Though, I didn’t check the voltage drop yet and thinking it would be better to resolder all of them for originals, to make sure that everything will be fine during regular operation.

Fake voltage regulators
Real one on the right. Be careful!

FedEx introduced new rules for the transport of LiPo batteries. So I had to go and bring the whole butch of devices to Paris, where we have an agreement for a meeting. The moment of the solemn transfer of the batch of ETG devices to our happy client. Gare du Nord, Paris.

NFC and positioning extensions for museums and exhibitions

Today is a great day. Because we’re finishing the great stage of developing of new version of ETG hardware. It is an magical NFC and indoor positioning system feature is coming. Soon, my dear readers, you will be able to equip your museums and exhibitions with tags and beacons, which radically extend experience of visitors of your exhibition / museum / city.

Imagine, you’re walking around the city and listening stories about everything around. One moment, being closer to museum that equipped with our tags, you are prompted like “this museum has ETG tags installed and ready for your visiting”. You’re getting in and listening the story about each object demonstrated inside. Isn’t that fantastic?

The night testing story

You won’t believe me. After the 3 month of preparation and polishing of the new add-on for our little gimmicks me and my robo-friend Creaky found the most stupid and ridiculous bug I ever seen. To make the story short: some days ago, when everything was done and new shiny version of PCB layout was ready for fabrication, I decide to go to test device outside, like I did before hundreds of times. That was night and I went to the street romantically surrounded by the shades of trees to make couple of circles around the house and enjoy the night breath… suddenly after couple of minutes of walk I heard the message “battery is down, device going to sleep…” a-a-a what the hell?

I start digging it and have been checking practically everything, without any result. At home everything works just fine, outside — nope! I was repeating this procedure several times invariably with the same result. Only with the advent of the first rays of the sun I’ve got idea to try it in the fridge. And viola, it start switching off :) Attentive re-reading of data-sheets gave me the answer: the ATtiny, which a was planning to use as a co-processor, is a very temperature sensitive. If you don’t use external crystal oscillator, most probably you will get significant changing of frequency, which is a deadly when you need to sync anything.

It is always pleasure for me and my robo-friend Creaky to fund solution or learn something new. Eventually the whole life is a permanent process of learning. However, the worst side of the story is that looks like I need to redesign the whole beautifully created module form scratch :( and it was so elegant…
