Dear Steve
Are the "Plug 'N Power" modules sold by Radio Shack the
same as the BSR modules you condemned in your July '83 article
"Build the RTC-4 Real-Time Controller", or have they remedied
the problems.
I have a need to control 20+ lamps/appliances in association
with a home security/convenience system at my parents
residence. Things like the pump to their solar-heated swimming
pool (sounds like the typical California stereotype doesn't it...),
the sprinkler system, etc can all be run with a simple on/off
control. As for the "Plug 'N Power" modules, they're a lot easier
to use than running wires with relays, but I don't enjoy throwing
money away either!
So how 'bout it, Steve. Are these things any better 5 years
later?
Thanks!!
-Jeff Kerner

If you will look at the current Radio Shack flyer, they are selling a toy to
control BSR/X-10 modules. There is now a company X-10 Ltd. that is the
division of BSR that makes any BSR "approved" module.
As I understand it, RS bought this gadget from GE who had it built to their
specs by X-10 before GE got out of the market. It looks like it will do what
you need.

BSR is no longer in the module business. A group of employees bought out the
business and the company is called X-10 (USA) Ltd. X-10 makes all the modules
and controllers that are private labeled and sold by companies like Radio
Shack, Sears, Stanley, and so on.
I did see that Radio Shack bought out GE's HomeMinder and is offering it in
their latest catalog. Looks like a good deal.
By the way, all the reports of false triggering and reliability problems with
X-10 modules during the past few years have been corrected in the redesigned
versions of the modules. The old modules were mostly brown and had the house
code and module number dials on the sides of the module. Those were the flakey
ones. The new modules are mostly ivory and require a screwdriver to set the
codes. They are completely redesigned and very reliable. A look inside
reveals marked improvements from the old design to the new.

Ken,
I wanted some info on the new modules and after a bunch of phone calls I was
able to talk to one of their engineering managers. He told me that X-10 was a
us} US subsidary of BSR, ltd. But what your saying may be the }ireal story.
I went ahead and bought one of the Homeminder toys. Its kinda neat. The cpu
board is sealed up in soldered box and all I could see through holes in the top
was a z80 cpu. Wish I knew what video chip they were using.
thanks

Apparently the new X-10 modules are better than the old ones (they seem about
the same in my experience, however).
Regarding the X-10 computer interface, it can be connected to any computer
that has one input and one output bit (a parallel printer port will do). You
merely send it TTL data which it transmits to the AC line. If you subscribe to
INK now you won't miss it.
To my knowlege, I believe Ken already has the transmitter running on the
BCC-180. The only thing holding up the article right now is X-10. They are
upset about how much detail I want to devulge about their system and they don't
want me to build and X-10 command receiver (which is the companion article).
I'm still negotiating.
Believe it or not, I proposed this $30 X-10 interface to BYTE and they didn't
want it. They (the editor in chief, that is) said it wasn't in the best
interest of their audience (maybe they have been writing to a different group
than I have). I should be looking at articles (mind you, not projects) that
have a broader appeal.

Eddie,
Thanks for the tip! I'll check it out. I haven't seen the flyer, though. I
usually get about 2 or 3 of those things and they usually get tossed out by my
girlfriend who diligently tries to keep my apartment from looking like the TRW
swap-meet. Any idea what RS calls this "toy"?

They call it "Homeminder". When it comes up with its id screen it has a GE
copyright. I went ahead and bought one and stayed up all night playing. (I
had a bucnch of modules I had nev_er used)
When I got this one, it was the only one in town I could f}iind.

The "Homeminder" is GE's failed attempt at what they called a "Home Control
System". It orginally retailed for something like $400 back in 1984. Radio
Shack got their hands on the thousands sitting in the warehouse and did a slick
job of reworking them. They covered over all the GE labels with theirs,
rewrote the manual with their name on top and even made a brand new box to hold
the system in. All this for $60 is a pretty good deal! I had to buy one just
to say that I had the first attempt at Home Control by a huge consumer
electronics giant! You should have seen the look my wife gave me when she saw
me take the thing out of the box (brand new) and proceed to rip all the Radio
Shack labels off of it! Oh well, living with a certified electronics kook, she
is used to seeing me rip apart brand new "toys". In any event, the point I
wanted to make is that wouldn't it be ironic if the first failed attempt at
Home Control by a major company turns into the first mass market home control
success by another major company (the Shack). I think the price is what kept
people away from products like this in the first place! Enough of the soapbox.
I really wanted to make my first message on the new system a really LONG ONE so
I could give this thing a good test. I love the new FAST RESPONSE of this
system.

Jeff, While the radio shack homeminder has some neat features the home control
system provided by Steve's byte article some time ago is quite a bit more
flexible than the homeminder. I am currently using one with about 22 modules
to control most of the lights in my home.Several are turned on by presence. ( a
passive ir detector sees you and the HCS turns the light on). I have been very
pleased with the reliability of the HCS and the relative ease of use.

Jeff, I have been tinkering with the BSR controller stuff for several years. I
have not found the units to particularly un predictable. I did at first and
spent a considerable amount of time researching carrier current operation
techniques. My research on this actually started back in college where I ran
the campus radio station on carrier current. The units, transmitters or
receivers are sensitive to line impedence changes particularly between phases
of the 240/110 VAC line. This can be overcome with a couple of tricks. I have
recently completed and am working on rev 2 of a stereo control interface which
is controlled by the BSR carrier signals (ie. I acn control my stereo from
anywhere there is a controller or a computer with BSR output capabilities).
Would love to talk about this home control stuff all day but in closing let me
say I puschased one of the Radio Shack/GE HOME MINDER. I think it's a neat box.

Subj: BUS INTERFACE
I have a small problem I hope someone can advise me on. I'm designing a project
that has a microprocesser that will have as a peripheral a modem chip. I want
the micro portion to run on battery on power failure, while the modem chip will
be powered by AC only. Obviously I can't just have that chip on the buss but
would something like anding the inputs to the output enable of a buss interface
chip, with the processor control line and a 5 volt line powered from the AC
only side provide adequate to provide isolation.(I wonder if I could make that
sentence any longer?) Hope thats clear enough. Any comments would be
appreciated

Steve,
Some time ago I called the people at X-10 trying to pry new information out of
them. I've lost my notes, but the guy I talked to was adamatly opposed to
releasing any info. In fact when I told him that I had an article in front of
me by you-know-who,he said, "well, thats just impossible; never heard of it and
it will never happen."
What is the deal with those people? Can they stop you from publishing an
article on X-10 toys?

Subj: REPLY TO MSG# 77 (X-10)
There's freedom of the press and reality. Sure, I can publish anything I want
but if I care that the info is to be use by the readers, its best that I don't
do it without the blessing of the company that manufactures the stuff that I
use in the article. Unfortunately, X-10 is paranoid. They think that every time
I tell anybody what's in their little boxes that the whole world is going to
rip off their design and put them out of business (perhaps this should be an
indication of just how solid their patent really is). I have an X-10
transmitter interface article planned for a future issue of INK (BYTE doesn't
want anything that reeks of home control anymore). The transmitter is made by
X-10 and the article would be on interfacing it to various computers. I also
plan a companion 120 KHz AC line receiver article that would allow full duplex
AC line communication as well as control. X-10 is adamantly against me
presenting any kind of a receiver and is screaming patents/law suit if I tell
you how to make a stinking 120 KHz AC line receiver. Well, I'm not thrilled
with anyone telling me what I can't do so we'll see about that. Unfortunately,
I want the device that they plan to manufacture (the transmitter) if I P____
them off then anyone reading the project will have trouble getting it. Instead,
I wish that a few of you guys would write to Dave Rye at X-10 (hey Ken. You got
an address?) and suggest that my writing article enhances their sales. BYTE and
these guys are all making a big mistake again. They think that "hacker" means
dumb and no money. But, what do you expect from people who never correspond
with their audience, only their ad reps.

Subj: REPLY TO MSG# 77 (X-10)
It would seem to me that X-10's main source of income is from selling the
little receiver modules by the zillions and not by selling transmitters. Any
OEM that puts an X-10 transmitter in their product is automatically going to
stimulate alot of sales of receiver modules. It would take a mega company,
like Black & Decker, to compete with X-10 on receiver modules and not Ciarcia
or Micromint. I've spoken with the folks at X-10 along these lines in the past
year and I really think they miss the boat. The first really good mass
marketed Home Control System is going to have and X-10 transmitter in it and
possibly even an X-10 receiver to process messages as well. X-10 will probably
want to sue the maker, but will look pretty ridiculous if thousands of their
receiver modules are sold because of it.
