This looks great, Fission Labs, but I have a few questions. I understand that version 2.0 of the link can use encryption for data transfer, but can it be backward compatible with Version 1.0? And how does this device handle frequency sharing when there are more than two calculators trying to link? Also, if you embed the link into the calculator, can it be turned off, and if not, how much drain does it put on the batteries?

What I have understood is that encryption is to allow more than one couple of calculator to transfer data at the same time, but that the frequency is always the same. I think you should make yourself something to turn the link on and off easily... is that right?
And I wonder for the backward compatibility too...

No, version 2 is a different system, they are only compatible with other v2 links. The data is encryted, and encoded, then decoded when it reaches the other link. It does not interfere with other links. The link is only active and using power while transmitting or receiving. But of course, a different power supply would save batteries.

(I take it your a ham?)
so, i'll say:

I have a question: If there are multiple calculators with v2.0 radiolink within 600', how does your calculator know which one to link up with?

It would be cool if Fission 2 could get some pictures of the Radiolink.

Why haven't you made both transmitter and receiver in only one PCB ? I don't undersand how it works for connecting. Are they on parallel ?

Finally, how far does it go in meters ? ~200 ?!!
6-8" wire antenna: 30 cm ?

there are 2.54 cm in one inch. Surely you can figure it out from there.

I certainly hope so CAVA.
NWO!!! Chat GG 4.2 all the way!!!

Cool.
I think I can not reach the fission2 website
(www.fission2.com/labs/radiolinc.htm)
right now. I kept trying from 14.00 GMT to 15.00 GMT (on 27.10.2000).
What's up with the website? Has it it's name changed ? Or is it only a temporary problem ? Or is it the personal problem of me and my network settings ?
I someone finds out something, please mail me.
Thx.

The server has been up all day.

The same thing happened to me at first, but then the problem vanished.

DO NOT press HOME after pressing F5, diamond, clear! This locks up the calc and the only way to reset is to remove all batteries!

F5, Diamond, APPS

HW1, AMS 1.05

I hit home after that, and nothing happened. I suggest you check your batteries, and your programs. Try doing it after you clear your calc.

AMS 2.05 HW2- It still locks up, I just listed the keys wrong.

What doyou mean? This is the only way for me to get out of it. Don't push catalog and then esc though.

The RadioLincs are finally done? It's about time :) I've been wanting to buy a pair of them for some time now... Though at one time they said a pair should only cost $30...

does anyone actually know how the encryption is suposed to work? I already have a few ideas for some near tcp/ip style communication with several of the different ways the links work if i can put more than 2 calcs on the same encryption band....anyone interested in assisting in a cross calc platform(ti83 83+ 85 86 89 92 and 92+) chat software capable of handling more than two calcs.....send a mail....or if u just want to give ideas.....thats fine to

i just want to say that is a totally awesome idea for a cross calc chat and that people are already developing programs before the actual device has been out. it would be really cool and helpful if lots of people had the radiolinc with an ongoing chatroom going on all day at school to help with homework and keep updated on everything going on. it could be like IRC, only on calculators. I guess that is until teachers figure it out and ban calculators in Lit or whatever. But until then, it's an awesome idea!

"The authoritators shall set the rules, and the authoritatees shall find a way to break them."
We, the calculator enthusiasts, are the authoritatees.

If we had a chat room set up with a lot of people in it at school, we could program it so we could get longer range. For example, if there are 2 people about 1200 ft away with a third person in the middle, to send it between the 2 people 1200 ft way, we could first send it to the third person in the middle and then have it sent it the the receiving end.

it could work kinda like gnutella then, computers linked to computers linked to more computers, only with calcs. but seeing as i have no experience programming with ASM or even using BASIC to link 2 calcs, i would have trouble making that program. more power to whoever can accomplish this little project!!

well, i got some more info from Fission labs.....and i am now workin on a pre beta for a cross calc platform chat program....i have really only programed for the 89/92+, 86, and 85....so anyone willing to help with the 83 and 83+ would be greatly appriciated
