The official Electronic Tour Guide project blog
Good news everyone! We are happy to announce the official release of the new hardware version of Electronic Tour Guide. There is completely renewed hardware including new processor, embedded RFID option and interface for additional modules like indoor positioning system and radio broadcaster. Please feel free to send questions and inquiries. We’ll be glad to have new partners and clients in other cities and see people walking with our devices all around the world.
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?
This is how Electronic Tour Guide RFID tag looks like (blue version). It can be placed near exhibits that you would like to tell.
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…
Hi kids, it is Creaky on the air again. It is a MAX1555 LiPo charging ICs. They are dead. It start to be obvious that it was a mistake to choose them for the first version of devices. Most of them just fried by the charging current, which is, surprisingly, not exceed parameters given in data-sheet. Besides, it is the most yummy and delicious things I ever try! Nyammmm
Bon appetit!
P.S. Actually we was switched to MCP73831 two years ago. This units from old devices that we’ve got for service.
that’s how it looks like :)
