Back to HackFurby. OLD NEWS 11/25/98 You can now subscribe to an announcement list if you want to hear about updates to this page through email.  This is an announcement only list, so you won't receive any $-related posts(nor can you send any). I read the IR specs and added them to the ir hacking section.  I haven't had much time to user the CIR(it only functions correctly on my office computer), but, based on the brands of remotes that furby responds to, I believe that its ir protocol is a space-based REC 80 format. Killed all the $-related posts in the discussion group. Took the fur and shell off of my Furby(as described in the furby autopsy).  Keep in mind there are 6 screws(two are under the foam padding).  There are 3 visible chips.  1 is a serial eeprom. HT93LC46 9834W8021-1.  It has 8 pins and is located between the large daughtercard and the back button.  It is built by MicroChip technology and has a data sheet here.  I think it is data storage only. 2 is a Hex Inverting Schmitt Trigger.  Whatever that means.  It has 14 pins and is located near the connection to the battery, the IR, the MIC and the food sensor connection. National Semiconductor made it.  P78TN MM74HC 14M.  Data sheet. 3 is very hard to see.  It is under EVERYTHING.  It has many pins.  To see the designation, you'd need to take apart the furby almost completely. 11/18/98 Added a discussion group for posts related to furby hacking.  Consider this group ultra-moderated.  No sales-oriented posts allowed(unless they refer to furby hacking gadgets).  There is too much noise in other groups.  We will avoid that. Added a report(Panasonic Power button sleeps furby). 11/17/98 Added a table of webtv universal remote codes and the reactions they get from my Furby. Darwin sent me an updated version of the CIR circuit diagram.  This diagram is really cool because it shows the components as they appear in reality, not as symbols.  Also, this version of the diagram uses a 9v battery for the ir receiver.  This seems to increase sensitivity.  I haven't tried it yet, but Darwin says it's great.  This diagram can be used with PowerIR and MonsterClicker.  Check them out! 11/10/98 Added 'Spanish Furby' easter egg(see reports section). 11/9/98 This weekend, I used a universal remote(the one that comes with WebTV) to mess with my Furby.  I found about 30 buttons from various brand settings that make the furby react.  I'll put up a table of my findings later this week. In the meantime, I also built a CIR infrared decoder/transmitter for use with the Monster Clicker software.  Tonight, I'll have the MC software learn each of the buttons that Furby seems to like and see if there are any similarities. 11/6/98 Put up this page.
