Subject: [alt-beam] Re: Curiosity killed the cat
Check out http://wollongong.apana.org.au/~ben/fred/
for the circuit and
description.
By the way, I think I've cured the 'long time lockup' problem: put a cap or
two across the motors. Thanks to Kyle Simmons for that idea! I used 0.22
uF and FRED has been happily popping away under my desk lamp for a good
three hours now. I'll update the schematics next week when I have time.
Just for fun I put FRED inside a clear sphere, miniball style. Who said
that the miniball was dead? It won't exactly break any speed records, but
looks kinda quirky.

Ummmm... where do you see black text? Do you mean the one in the mouseover
buttons or the section titles? Thats on a light sky blue background, and is
highly visible (at least on every computer and browser that i've tested)
Please tell me if you see things differently. I've also made the hyperlinks
in the news section in highly visible cyan, and mailtos in yellow. Those
also stand out from the darker grayish blue background. Maybe its browser
problems....
later

The "Acceptable Use" guidelines say nothing about this, thus it would
seem ok providing it met the other guidelines (eg is on topic, polite,
etc)

Nope, it might just be apathy - your questions may have come soon after
similar ones or not interest very many people. On the other hand, I've
posted something twice now that has never appeared, but everything else
I post is fine. I think I'll try again. (And if someone is blocking
posts, for goodness sakes let us know so we can fix the offending
aspect. Common decency!)

It might look like there are a lot of circuit links on the Beam Web
Index, but there are _huge_ gaps to be filled (most of my bookmarks were
out of date). For example - there is nothing on the basic microcore -
the heart of BEAM! (Wilf's specialised/advanced uCore circuits were the
closest I had). I've seen _heaps_ of advanced or alternative photovore
circuits (demonstrating great ideas) that really should be there,
likewise solar walkers, and circuits to solarise walkers - there are
currently _no_ links (Bush Beam Tek had a lot of this, but my link is
broken). The Miller Solar Engine (among others) isn't there, and the
Sensor section is lacking (I also think sensor sub-systems such as the
capacitor-resistor "timer" arangement for feelers etc should also be
there), and the General section should ideally contain a host of
circuits that inspire new ideas and/or demonstrate procedures that could
be applied to BEAM, in addition to misc circuits that are directly
useful.
Look in your links pages - more BEAM stuff is not listed than is, you
should have no trouble spotting useful links that are not in the Web
Index, and send them to Bruce at Bruce_Robinson@telus.net
I've opened my bookmarks, now I wanna see yours, damnit! :-)

I never saw the original Justin. Who's it from, and how did you manage
to get it?
The only "blocking" on this list is:
- messages containing certain keywords, like "u_n_s_u_b_s_c_r_i_b_e"
(as zoz recently discovered) are automatically filtered out. Makes
sense, actually ... it keeps us from getting all those mis-directed
messages that are supposed to be sent to a different address.
- Spammers, when identified, get taken off the list PDQ.
- People who mess around with other people's IDs and so on may get
unplugged.
Aside from that, we're pretty much a self-regulated group. The list
admin might send a comment (not very often), but I've never heard of him
actually blocking a post.

Watch it! That URL is obsolete. Change it to the new one.
http://www3.telus.net/rfws/bwi/index.html
My ISP changed names half a year ago. The old URL will die in September.
But more to the point, is this your re-posted message, or someone
else's?
I've had a few quirky things happen with e-mail, such as seeing one of
my postings appear on the list 2 days after I sent it. That could be a
problem with my ISP, or the mailing list ISP, or some system in between.
I also had no messages from anyone for 36 hours (impossible when you're
on this list :), followed by a huge dump of messages, including a bunch
of duplicates. I looked very much as though my ISP was able to receive
messages, but not pass them on for a couple of days.
