Re: Bluetooth Vic20

Hello Beamrider,
I really like the idea of playing back samples stored on the phone.
I haven't really thought about selling these devices because I didn't think that many people would care to buy it. But, if I'd think about it now then what would be the max cost? Parts cost is one thing this doesn't have to be an issue... but considering it requires the bluetooth device, the connector and a small PCB but most certainly a nice case, I hate those bare PCB designs. A device that isn't properly encased is easily damaged. Then it must be put together which isn't a great deal considering the limited amount of parts. But an hour is easily spend. Then it must be packaged in a box so it can be safely shipped. All in all this adds up.
I doubt if it will be worth the effort if you can sell it for not more then €20,- because if it would cost more then not many people would be willing to buy this. To keep the device building costs as low as possible the volumes must go up.
Not many people will be writing programs any more, so there have to be some killer-application to use this device.
We have to consider that the speech functionality is only supported by Scott Adam adventure games of which there are a few.
So there has to be an extra function to make it interesting for a wider public.
Transferring files could be an option, but at 2400bd... it would take approx. 17 seconds to transfer a simple 4k file, which is acceptable.
But faster rates would be preferred, which isn't easy considering that the port isn't really designed to go faster.
The loader routine must already be present in memory, so this will require the user to load it from tape or disk (or the good old type-in-listing) before transfer of data can take place over bluetooth. This doesn't have to be a big issue but must be kept in mind because this prevents it from being a standalone solution or competing with a diskdrive / more modern SD-card based solution.
The most troubling issue I have with modern technology (like phones) is that I don't expect it to last as long as the CBM computers do. Because smartphones will eventually suffer from battery problems, although this can be easily solved with connecting it always to the charger. The VIC-voder doesn't have this problem. It is based around a raspberry pi, and is completely stand alone, not connected to internet or anything else that might enforce a destructive update to it. But then again... it overly expensive and complex for it's task, but I can see it's charm. And those interested in speech on Scott Adam games should certainly give it some thought.
The project you and I build is great for learning how programming app works, and playing with bluetooth and the VIC-20.
I had a lot of fun doing so. And I'm sure you did also. Feel free to use or modify the program I've written.
What I really hope is that others (like you and me) will be inspired by this in some way and get bitten by the development/tinkering bug.
(sorry for the long text... I didn't really mean to make it this long)
Kind regards,
Jan D.

PPS: I've also seen your VIC-20 pooyan game on youtube, wow! That is really a great port!
