Title: what i have been up to, thus far.
Post by: travis_farmer on May 06, 2017, 05:48 pm
Aside from doing quite a bit of mind-numbing research on building my CNC router, i have spent my weekends gutting out my old camper, as i plan on renovating it to become my portable CNC shed, as it is the only place i have available to put it, where it won't be in the way. the camper is a 29' dual-axle monster, and it will give me plenty of room for my CNC.
I will have to re-structure some of the walls for side-to-side structure, if i take it down the road. but for the most part, it will be fairly open. so i will have room for the control computer, and other supporting electronics. it will also have room for some basic storage for spare parts, and other tools.
I will be getting a little bit of money back from my tax return, so it will enable me to get a good start on my latest project.

Also, i was finally able to register my motorcycle, so after a spring tune-up, and after the weather turns better, i look forward to be out on two wheels again. I will have to be careful my first time out, as they have not yet finished cleaning up the road sand from this winter.

I haven't been posting much lately, mostly due to whenever i do, i seem to go against the grain of someone, somewhere. but heck with them, I'm going to post anyway!  :smiley-razz:

as far as Arduino related projects, i have discovered a method to make a CNC pendant with an Arduino, for LinuxCNC. so that has been occupying the design portion of my brain, lately. if i get it to work, i will likely post my results to the forum. it is based on somebody else's work (https://forum.linuxcnc.org/18-computer/22562-arduino-based-usb-pendant-for-linuxcnc), but i will be making a few design and coding changes. and i plan on using my Xbee to make it a wireless pendant. :D

Adafruit has a really nice battery charging/management breakout board that is small enough to fit inside a handheld. That way you can use a rechargeable lion battery to power it.


I'm using one to provide battery back up to a wifi enabled freezer alarm. I get text messages if the freezer is warming up above 25 degrees, or if power is lost. (Wifi on APC) If goes above 32 a loud siren goes off and I get that alert as well.

Saved my food a few times already because for whatever reason I have a hard time getting the door to fully close.

Post by: Qdeathstar on May 17, 2017, 01:51 am
topic needs pics.  However you probably do not need a rotary phase converter (450) for the money, you can get a static three phase converter for relatively cheap(150).  You'll have reduced power to the motor but it might still be better than the makita. How much did it cost?
Title: Re: what i have been up to, thus far.
Post by: Qdeathstar on May 17, 2017, 03:10 am
basically, it goes panel to disconnect to converter to machine. But, after commenting i did some more research and basically it is a bad idea to connect a cnc machine to a static phase converter because it not only affects torque, but also spindle speed, which, as you know is very important to a cnc machine.
Title: Re: what i have been up to, thus far.
Post by: Qdeathstar on May 18, 2017, 03:29 pm
I'm not too familiar with vfd's, but they guys at the CNCzone say you have to isolate the spindle from the rest of the machine/steppers. They seeemed unimpressed, but the same guy was pushing a particular phase converter as the only solution... and I know a rotary phase covertly will work, so consider the source...

Post by: Qdeathstar on May 30, 2017, 01:04 am
What about a tarp. Not resting on the camper, but situated just over it at an angle. During the winter just put some heaters on top of the camper and it will keep the tarp above freezing so the snow will melt off, or, alternatively cause a really neat bon-fire ;)

Don't recommend applying grease to surfaces, they will get all gummed up.

Maybe a very very light film of spray silicon, but only after you prove it is necessary.

That's the opposite of my manual, go figure.
I do not understand why they say silicone will damage things.

I am sure you will find grease will turn into mud as the cuttings mix with it.

Cleaning after every use will help, but laziness will soon raise its ugly head.

Hmm. I thought you could set the current to steppers lower that what they need.... for testing, at the sacrifice of acceration, top end speed, and holding torque. I have a nema 23 motor that i am planning to use as the z stage in my printer but it wants 2.4amps and the duetWifi only outputs 2.2 amps... i had planned to set the digipot to around 2amps as the z stage only had to move relatively slowly.
Title: Re: what i have been up to, thus far.
Post by: Qdeathstar on Jun 23, 2017, 02:25 pm
Yep, in order to get 5amps out of them you'd have to put the board in the freezer. But, I think there might be something wrong if you cannot move your gantry with no load at lower current....

travis, if you need high current power supply's for cheap, look for server power supplies...

12v 100amp supplies can be had on amazon for ~40 bucks.


Did you buy the converter from aliexpress or ebay?  ebay almost always finds in the buys favor in disputes... either way i would open a dispute right away and ONLY CLOSE IT once you are completely satisfied. If they make good on their end you can close the dispute with no harm done..

you want to put the drag chain diagonally from one corner where the wires enter the drag chain. Amazon has got a wide selection, and you can just join the cable togheter if you need longer pieces.

Looking good! I have been debating for a while, but I think if i am going to choose between a CNC machine and a milling machine im going with a milling machine :D Once i get enough money for the CNC after i have the milling machine i can MILL PARTS for the CNC machine, like that mount for instance. Why buy it for $50 when you can make it for a little under $300 :D.

This may be a good time to shop for leds. You could have extra lighting to beat the winter gray ready before Halloween snow.

I did get my $2 led disks working cooler by blinking them fast, 1ms ON/OFF and still they're too bright to look at without seeing afterimages. I switch power between the two (a PORT write, both switch in the same cycle) to have the least draw, I might be able to power 8 disks with a 1 Amp 12V supply.

Each disk has 36 led junctions all wired up for 12V. I used cheap (paid $5.something for 50) MOSFETs, 1 per disk.

If you have a Harbor Freight nearby, think about the free or on sale many-led flashlights as light sources. You only need to replace the batteries and hack a mount to brighten a dark corner.

See what deals you can get while you have weeks to get them. A little here and there, you could build a nice lighting system.

Just watch for sales that won't be there last minute. You can get ready to build in leisure if you tortoise it along while there's time.

It's like splitting wood. You don't wait till October do you?

About the CNC camper. You could suit up and stay out there for hours. But what are the chances that when you go to leave a snowdrift has piled up against the door? Well, not real high but not exactly unheard of either!

you could potentially add counterweights on the z axis. People do that with deltas for flying extruded mods. Alternatively, you could get some pulleys and use them to drive the z axis to gain some mechanical advantage. Springs seem like they might increase backlash, but if you don't do any/a lot of z-lifts then it doesn't matter to much, maybe.

If anything is being harvested maybe get a bunch cheap? Peas maybe, they taste so good fresh.

Or get down the coast and buy lobsta off the pier?

There's someone in Franklin Co. with a laser tag arena but I dunno if it's up and going yet.

Some time look on youtube for warping concrete. It's glass fiber reinforced (GFRC), they pour out flat shapes, wait for it to set a bit then bend the crete like you would steamed wood.

Look a bit more into fiber-crete with wood shavings or paper pulp. If you like it, you might take it somewhere.

i also have to work on the Hall-Effect home/limit switches for my CNC, as well as devise a way to help support the Z-axis.

~Travis
If you set the linear Hall sensor and magnet up and then slide a piece of steel (can metal will do) in between, it should read less to nothing.

If you can read the magnet through a hole in one piece of steel and slide another in to shut it off then you have diminished the sense area. I have no real idea of how small a hole can work.

If you move the magnet across the direction that the Hall sensor points, the read values should peak when they are directly across from each other as long as the magnet is pointing at the Hall switch right then.

Make yourself a Hall sensor wand and have fun probing magnets and EM fields. If you combine a magnet and Hall sensor then you should be able to detect moving non-magnetic metals. You can use the wand to detect EMF in your own projects.
Title: Re: what i have been up to, thus far.
Post by: GoForSmoke on Aug 16, 2017, 07:13 pm
You need a Linear Hall Sensor, not a Hall Switch. The Hall Effect is used in many different devices, just because it says Hall doesn't mean it's the Hall you want. For your limit switch, maybe good but for probing EM fields and finding out what's going on you'll want the linear sensor and probably some kind of sensitivity control circuit.

You might want the linear Hall finding where the magnet field is strongest as that may provide your best zero.

A linear Hall sensor has a direction along which it measures field strength. You get strength and direction. If you make a wand that points in the direction and lets you get the sensor away from your hand then you can find the invisible shape of the field.

You can get more precise stops with light and use the Hall or cap sense to tell the motor to slow down, fwiw.

With 2 slits and a red led you can probably get an interference pattern. That will gives bands of light to sense and if the distance from slits to sensor is small, the distance between bands wil be smaller... you'd need to mask the sensor to see only narrow light or dark band alone.  And no, you don't have to have a laser to do the double-slit experiment, it's just more clear with one.

I was steered away from optical (on CNCzone), as the router dust may obstruct the sensor, unless i build it into a sealed mechanical sensor that passes a vane through the sensor. seemed like hall would be easier to implement, of the non-mechanical sensors.
So true about the dust and all.

With the linear Hall you can delineate mag field through or not holes or slots in sheet steel, or how moving metal affects an existing field (gear tooth counter) or whatever else might seem neat for whatever use it may have.

I thought my soldering skills were at least passable, until i tried to solder a PL-259 connector on to RG-8X cable.  :o
first try: melted the foam core, shorted.
second try: works, no shorts.
third try: melted the foam core, shorted.

i tried my electronics soldering iron first, and got a lot of gobs of cold solder due to the thermal mass of the PL-259. then i tried a small butane torch. no more cold solder, but the heat is a bit too intense. the you-tube videos make it look so easy. and i tried desoldering the connectors for re-use, and only managed to completely melt the insulator.

This is for limit switches, right? The CNC part needing movement limiting is steel? Stick a magnet to it and start probing for fastest/brightest blinkies. Hold the sensor still and move the part with magnet under it. There will be a brightest zone.

The old fashioned microswitch is accurate and extemely repeatable - I doubt if you'll be as accurate with a Hall device...

The CNC is mostly aluminum, so the magnets will have to be attached with some sort of adhesive, like epoxy.
Well there you have luck, what you attach to the frame won't be affected by it.

You can be very accurate as to position with a linear Hall sensor. That's what I want you to see.

With a bar magnet you have field pointing out full strength each end that varies throughout the length of the magnet between N and S, with + and - readings depending on which way you point the sensor. If you adjust your circuit, you can read 0 to 1023 on an analog pin, your precision is the distance from N to S pole divided by your analog read max value. Errors in the length of your magnet are also divided by analog read max.

Stick a button supermagnet to a flathead steel nail and check readings from nail tip to head always along the nail axis pointing towards the head. That should match how the nail and magnet attached to the CNC frame would move under the sensor. You may need to tune the sensor circuit to reach 1023 at the head, perhaps with a turn pot.
With the linear sensor you can watch the limit approach. That's what I want you to see for yourself with a DIY Hall EM field probe.

A precision joystick runs 12 or more bits analog read, linear Hall sensors are commonly used since they don't wear out or need cleaning. These are instrument quality devices unlike Hall switches used in door and window intrusion systems.

Mess with the fields, make the thing that lets you read them! You already spent the nickel, get your time out of it!
That probe will let you find EMF sources better than an unterminated jumper.

Hi,
Quote
I guess my current frustration is my Kenwood TH-28A 2M (Ham) radio. it stopped working, with no known reason.
Sorry I cannot help you, BUT!!!!

I have seen that you have tried to help yourself with advice from the HR Forum.
GOOD.
You have described your problem.
GOOD.
You have taken advice.
GOOD.
You have a service manual.
EXCELLENT
You are trying to identify problem areas.
GREAT.
You have said you will try a mic/speaker ,when it arrives.
GREAT.

1) DO NOT BEAT YOURSELF UP because this highly complex and small device has malfunctioned.
2) DO NOT BEAT YOURSELF UP because you are not having any major success. This will be caused by the fact that it is  a highly complex and small device.


Here I am talking to you, you who has assembled an got operating a CNC machine in his van in his backyard!!
Maaateeeeee.. (I could put an expletive in here!!!!!   :) )
I wouldn't even try that, and I'm an engineer.

Look at your accomplishments.

You can only use the smarts you have (and you have lots of them) to do so much.
You admit to your disabilities, I tend to think if you acknowledge them, they are no longer disabilities.

This is where you need an "Elmer" who can provide some local technical support.

I have a suggestion with your Kenwood.
Get a note book or A4 page.
Put a line down the middle.
On the left write the problems with the radio, on the right write (pun intrnded) the possible faults.

Then investigate each, crossing them off as you go.

Do not be disappointed if your attempts do not find a solution, you have not failed, as you have used ALL your abilities and that is the best anyone can do.

I agree with @allanhurst
It would then be time to find a Radio Tech to help.

Look at my side bar on this post, most of my bench work is repairs, repairs of equipment that have no schematics, (cos the manufacturer wants the customer to spend, spend, spend on new updated gear when the old fails).

The repair success rate can be as high as 80% with equipment that is in popular use, eg temp controllers etc.

But as low as 0% with a one off bit of gear that you do all the basic checks to and component updating, (ie electro caps) and when you turn it back on you have not advanced to step 2, and not solved the problem.

Or identified the fault, but its obsolete or a new replacement is cheaper than new part.

I have a time/cost parameter in there to stop me too, but I don't like leaving a bit of gear unfixed.

Life goes on mate...

Tom..... :)    (I need a coffee..)

Three foot should be OK for I2C but it's not really designed for anything off the board.


I'd just use the watchdog and not bother tracing down the issue, it's not like it's a critical device. If you are using i2c with that control it could be the i2c communication causing the lock up... I am using i2c between an esp8266 and arduino due and sometimes the due locks up, and I've done some reading and it seeems like i2c transactions can cause it as well...

I2C is board-level stuff - not meant for any distance. I'd not trust it for much over 1 ft. But you might get away with it....

Travis, as an aside, somehow i went back the the first page of this topic.. the router was three phase, did the VFD work? Or did you go some other path? Since the topic started i have gotten a lot more familiar with them because i have purchased a mill that has a vfd built in.

Apparently VFDs are awesome as they allow you to control spindle speed very easily on a three phase motor.

Surely there is very little carbon in the ash of a wood furnace - it'll all ( nearly ) be burnt.

There will be the dried remants of various oxidised products of the tree's metabolism - which depends on the
tree and the environment in which it grew. Various salts will be present.

Probably quite a good insulator when dry - but also hygroscopic ie will atract moisture, upon which it will become partially conductive and also corrosive.

So a good idea to keep it away from electronics.....

There is software, but it costs 1000s of $$ or it won't let you put out more than 30 lines of GCODE, from a quick googling. On a CNC lathe i imagine you only have to control x and y and then figure out a way to control the RPM... with a vfd maybe that isn't that difficult however.

What of drone was it? I have a phantom 4 and i had one of the original phantoms. I havnt crashed the phantom 4, and i doubt it would survive impacts as well just due to all the technology.... but my phantom 1 ran out of batteries and landed in a river and sunk to the bottom. The battery wasn't any good but other than that the drone still worked fine.

I've crashed it again since then and one of the motors has a pretty big dent in it, so i have been meaning to turn it into a foldable tricopter, though there are only so many hours in a day :)

And that was money you didn't have for indoor lighting. Now you really don't!

Can you get ahold of a lot of wood chips? Big piles left out "cook" from bacteria inside, get low-cook hot inside, steam outside...
So if you put a tarp on one side of the house high enough to pile 4+ feet high of chips along as many feet as you got chips then if that pile starts "cooking" and keeps going you could have a warm wall inside and warmer basement. I've seen wood chip hills where developments went into places, they steamed.

A better thing would be to build a methane digester and use the gas to cook and heat inside. All the wood and food scrap you get can feed the heater but it would take a big digester. Look on Youtube for ups and downs.

Hi,
I have the Aussie  "NBN", fibre to the house, with phone.

They didn't tell us that the odd, irritating beep,  that sounds like a smoke detector battery going flat, was also the sign of the backup battery in the NBN box, on the skirting board behind the TV, was going flat, its needed basically to keep phone alive during black out.

The trouble was when they installed the inside NBN box, next to the WiFi box, they installed them to close together, and  you couldn't get the battery door open to change the battery.

in other news, my weather sensor set should show up today, at some point. i just have to figure out the best place to mount the sensors, and still be able to get to them for adjustments or repairs. the solar radiation shield for the thermometer, and other stuff (humidity, barometric pressure, and whatever else) can all be mounted low.

She recovered, but not full function, fortunately she only needed 24hours of dialysis to come good, but  then had to have regular blood tests.

I get about 5 years out of my weather stations, UV certainly takes its toll, especially in the wind vane and wind speed cups.
My last one died after a lightning strike about 1/2 a km away, when I took it down, most of the plastic was stuffed or lost its shine and one of the cups fell off due to UV of 5 years.

The only thing that was recoverable was the rainguage unit.
The main electronics looked okay, but no Tx.

A lovely Spring day here... lol

you can put a small fan instead of all that foam and it will take care of the solar radiation. Thats what my vantage vue does. It's controller is inside of an insulated box, then all the data plug in using rj45 connectors.

I think if you had a solar panel that output 7v, then use a linear regulator to output 5v it would provide enough heat to keep things warm enough in an enclosed space.

As for my weather station, i think i have found a location for it, maybe. before making it a permanent fixture, i will have to set it up, partially, and see what it reports. i was thinking of mounting a 20' (or more if needed) pole somewhere near my CNC camper, and use the front of the camper to house the data collection, the batteries, and whatever i figure out for data transmission. i may be able to use the pair of Xbee modules i have sitting around.
Unless your pole is a foot thick (telegraph pole size), at 20' it will vibrate in the wind and shake your weather station to pieces. Also, you should set it deep into the ground and surround it with concrete.

Hmm, that may complicate things a bit. didn't really think of what the wind would do to the pole.
Guy ropes (steel cables?) may help, as would a shorter pole. It you decide on steel guys, remember that you'll have to account for expansion/contraction due to temperature variation.

Many overhead power line poles  where I live are braced with steel cables and tensioned with  turnbuckles.

They seem to survive the seasons without adjustment

It is only going up 20ft...  Get a 30ft flag pole and be done with it.

You only need to but the aenometer on the top of the pole. Telescoping for easy retrieval.  If you don't but a flag on the pole and just but the aenometer on top, it won't wobble to much. These things survive huge sails being attached to them (flags) a couple of pieces of plastic won't be a problem.

On my pole, (i am using it has a flag pole) there are already pins that hold the sections of the telescope up. The pins only go in two ways (180 degrees from each other) The pole i linked to you is a cheap model and therefor probably only has one pin, which means it will only go together one way. On the base, you set what that way is by rotating a first leg and screwing in a set screw.

-40c?

yeah, i was disappointed to learn that's only -40F :(

Kidding, right?
The Fahrenheit and Celsius scales intersect at −40° (i.e., −40 °F = −40 °C).

yeah, i don't store that information in my head.... i know 0c freezing, 30c hot,  and 100c boiling. Other than that DONT CARE.

Maybe your next project should be a squat counter.

The earth rotates once in 24 hours, so you need that rev rate...   1/1440 or  about 0.000694 rpm.

I don't think a stepper would work, since it has discrete steps, you would notice the steps....

Hi Travis,

For your tracker drive system , you may get some ideas from the DIY  Barndoor Trackers that track cameras.
