I don't have a gas chain saw (just an antique electric one without
guards). The Hitachi version of a sawzall might have been better but I
think the blade had gone walkabout.

Cordless drill: Great, especially when you have at least 2 batteries
Cordless sawzall: okay
Cordless circular saw: pretty much useless
Flashlight attachement: Great because it sits up nicely when in the
attic

The power tool that I really don't like using is the table saw. Much
more so the slider radial arm saw, and way more than a lathe or mill.
Apparently the first thing most folks do is remove that stupid thing
that marks up wood and helps keep it from randomly flinging stuff
toward you at high velocity (riving something?).

I avoid battery-powered tools. They are wimpy, and the batteries will die in a
year or two.

You have a cellphone?

Sure, a simple one. I charge it about every other week, and I've
replaced the battery once. But it's not a power tool.

You're not going to get a horsepower or so out of a battery for long,
especially when the battery is two years old.

You're not going to get a "horsepower or so" out of a hand tool.
You're in the stationary tool realm at a HP (Craftsman HPs don't
count).

120 volts, 15 amps is 1800 watts. Lots of circular saws pull 13 amps,
1560 watts.

Cordless circular saws (even small 6.5" ones) are close to useless.

Not so. I have a DeWalt that's quite nice on plywood and such. I
also have an older Makita that's great for cedar siding. It sure as
hell beats a 10lb. corded monster when you're trying to trim a piece
of siding, 15' up a ladder on the side of the house. ;-)

I've got a Hitachi one that came in a kit- cut up few ~2" branches
that were felled by an ice storm and it was already dying.

A circular saw used on a tree? You must be suicidal. Cutting a 2"
diameter branch with a 6" saw? You *have* to be! Haven't you ever
heard of a chain saw, or even a reciprocating saw? ;-)

Aren't trees still made out of wood?

Yes, and fingers are still made of skin and bone; much softer than
even wood. Circular saws are very dangerous things when used by a
someone with no respect for them. They are *not* designed for this
sort of thing.

and a chainsaw is safer?

Than using a circular saw as a chainsaw? You bet your ass! That is
what he's doing, in fact. There is a reason these tools exist.

I can't think of any use of a circular saw that makes it more dangerous
than a chainsaw.

Then you can't think. Each tool has its uses and its dangers. Using
the wrong tool is always dangerous.

I have noticed that, most of the time, there is something within reach
that will work well enough.

Yeah, a friend thought the same thing about hammers, until he used a
framing hammer to drive cut nails. Some ten eye surgeries later he
figured out just what a mistake that was.

Cordless circular saws (even small 6.5" ones) are close to useless.

Not so. I have a DeWalt that's quite nice on plywood and such. I
also have an older Makita that's great for cedar siding. It sure as
hell beats a 10lb. corded monster when you're trying to trim a piece
of siding, 15' up a ladder on the side of the house. ;-)

I've got a Hitachi one that came in a kit- cut up few ~2" branches
that were felled by an ice storm and it was already dying.

A circular saw used on a tree? You must be suicidal. Cutting a 2"
diameter branch with a 6" saw? You *have* to be! Haven't you ever
heard of a chain saw, or even a reciprocating saw? ;-)

Aren't trees still made out of wood?

Yes, and fingers are still made of skin and bone; much softer than
even wood. Circular saws are very dangerous things when used by a
someone with no respect for them. They are *not* designed for this
sort of thing.

and a chainsaw is safer?

Than using a circular saw as a chainsaw? You bet your ass! That is
what he's doing, in fact. There is a reason these tools exist.

I can't think of any use of a circular saw that makes it more dangerous
than a chainsaw.

Then you can't think. Each tool has its uses and its dangers. Using
the wrong tool is always dangerous.

I have noticed that, most of the time, there is something within reach
that will work well enough.

Yeah, a friend thought the same thing about hammers, until he used a
framing hammer to drive cut nails. Some ten eye surgeries later he
figured out just what a mistake that was.

is there a special hammer for cut nails?

Yes.

tell me more.

It's *not* hardened.

If somebody wanted to buy one, what would it be called?

An unhardened hammer like a sledge will work. A framing hammer is
much too hard and will shatter, along with the nail. They're meant for
unhardened nails.

I avoid battery-powered tools. They are wimpy, and the batteries will die in a

You have a cellphone?

Sure, a simple one. I charge it about every other week, and I've
replaced the battery once. But it's not a power tool.

You're not going to get a horsepower or so out of a battery for long,
especially when the battery is two years old.

You're not going to get a "horsepower or so" out of a hand tool.
You're in the stationary tool realm at a HP (Craftsman HPs don't

Interesting. It never crossed my mind that sledge hammers are not

Hello Jan,
It seems you had some experience with this LG Hombot..., so after you know how it was assembly, can you show picture or explain in more details how to open this device without broken it first.
Thanks,
Gid

LG hombot robot vacuum cleaner disassembly



I got the open source software from LG,

but no reply on my request for a service manual,

and could not find out how to open it without damaging the plastic.

Anyways It started screaming error messages at me,

and stopped working altogether.

Now that is a guarantee case, but sending it back, paying for return shipment,

just to get an other defective one back?

So, after it kept screaming and the whole neighborhood was now looking what was going on

'HOMEBOT CANNOT CONTINUE THERE IS A PROBLEM WITH THE SUCTION MOTOR'

I wanted to shoot it, I remember Elvis once shot a TV set..

anyways, wanted to see what was inside, wanted to re-design the piece of shit (do not buy this crap!!!)

so as it was not working anyways, decided to open it the smart and fast way,

dropped it from 1.5 meters on a concrete floor.

that did it.

Red (warning color!!!) cover flipped of, and there were a couple of real screws exposed.

removed these and had a look inside.

This is the main board:

http://panteltje.com/pub/LG_hombot_main_PCB_IMG_4432.JPG

The huge white 'chip' in the middle is from these guys:

http://www.minfinity.com/eng/page.php?Main=1&sub=1&tab=2

The processor or whatever it is says ST on it



The 'suction motor drive' detail is here:

http://panteltje.com/pub/LG_hombot_main_board_2_sucktion_motor_drive_detail__IMG_4434.JPG

nothing wrong with the motor, this seems just a MOSFET, motor in drain,

flyback protection diode D21, and sense resistor in the source (R100),

and mystery component BD16, there are several BDxxx in its motor drive circuits, no idea what it is.

The sense resistor seems bad soldered, maybe the solder connection drops too much.

Will put that motor on the lab supply later (just a freaking simple permanent magnet type DC motor).



An other mystery component, could be camera, there are supposed to be 2, one looking up and one down,

would have been more clever if one was looking were it was going, my plants for example!!, idiots.

http://panteltje.com/pub/LG_hombot_mystery_component_IMG_4435.JPG



Anyways maybe the repair group likes this info,

the top red bezel is fixed with click clack plastic hooks, the 'entrance':

http://panteltje.com/pub/LG_hombot_entry_door_back_with_hooks_IMG_4438.JPG



Seems a hobbyist design on a bad day by just arrived interns.

'Look we have a robotic vacuum cleaner to.'

Its hight is too high (cannot get under anything).

It get stuck on everything (carpet what not).

I throws over plants.

It scream swith a very loud female voice all the time (into the distortion),

even if you activate 'mute' it screams 'MUTE HAS BEEN ACTIVATED'

Morons!!

And it destroys any cabling you may have, pulled out the wires from the speakers,

grabbed an ethernet cable and pulled it all the way, just pure luck it did not pull the camera connected to it on the floor..



My first LG product, and absolutely and 100% certain my last even if I got one or ten for free.

Wrote it of, see if I can do better some day, with the parts.



There marketing is good, maybe they write their own reviews like Samsung.

This article and the photos helped me open up my LG Hom-Bot 2.0 in order to disconnect the speaker (which was always beeping in the middle of the night).

First I removed the red thin plastic cover: no screws, just plastic clip-on

Discconnected the connector of the "keypad".

Now 5 screws are visible below.

Then I removed the thin black outer plastic cover: no screws, just plastic clip-on

Now a 6th screw is visible below.

Removed 6 screws.

Now I had access to the speaker connector.
There is just 1 speaker and the connector is easy to see and disconnect.

Now I have a silent LG Hom-Bot 2.0, no more disturbing nightly beeping.

Here are all the photos (in random order).


LG Hom-Bot 2.0 disassembly; opening LG Hom-Bot; disconnecting speaker in LG Hom-Bot 2.0;
first remove 2 plastic coverings (no screws, just click-on); thereafter access to 6 screws in black plastic top.

Hi Jan,

I understand this is a rather old post, but you're the first guy I find who says he actually received the source from LG.

Any chance you still have it somewhere and could upload or send via email/skype/...? Might be a big help to me and my trying-to-mod friends :)

Thanks in advance,
Clock
