Goodbye Nextthing.co

This is only tangentially about the GruePhone.  It appears that NextThing computer company has folded (probably actually ceased operation months ago)… apparently it has closed up shop and left a lot of people with outstanding (paid-for) orders unfulfilled.  This is sad on many levels.  It certainly sucks for people who are out the cash, but […]

Wumpus

In a flurry of activity, I’ve added yet another game.  This time the classic “Hunt the Wumpus‘.  It’s fairly faithful to the basic version, though the numbering of the rooms is different (still a dodecahedron though.)  For those not familiar with the game, you are an intrepid explorer in a cave with 20 interconnected rooms.  […]

New games

I’ve gotta be better with these updates.  It’s been about 10 months since my last post. Work on the new phones is slow to non-existant, but I finally spent some time getting the old phone in better shape, both hardware and software. First, the phone is now back in one piece after sitting disassembled for […]

New (old) phones

One of the problems I had at the maker faire was that people wanted to try different games, but enabling them all at once caused problems.  I’m working on a software solution to mitigate some of those problems, but my wife suggested that next year I can have more than one phone available to use. […]

Maker Faire round up

The Maker Faire was excellent, even if there was a significant hardware failure that took the phone off-line for part of Saturday and all of Sunday. It was too noisy to even attempt to play Zork, so I had prepared the framework so it could run a much simpler game called Moonglow, written by Dave Bernazzani […]

Demo of a short game

This is the first demo of the phone more-of-less complete.  You can see a video over at my facebook page.  Apologies for those who don’t use facebook, but the raw video is too big for wordpress to handle. After the demo, I decided that it was time to tear the phone apart and try interfacing […]

In the phone

So, after a several month hiatus, I’m back at it.  I managed to get all the parts into the phone, though to make room I had to remove the bells from the ringer mechanism, which makes me sad. You’ll notice the USB cord hanging out the back: that’s for charging the on-board 1,100 mAh LiPoly […]

Full handset functional

So it turns out that the transformer wasn’t necessary.  I broke out a pocket oscilloscope, and it boosted the voltage from 1.5V pp, to 7.5V pp, and the resulting volume in the earpiece was VERY LOUD, so I tried without the transformer, and it worked perfectly, and at a much more reasonable volume with the […]
