Ooops! Sorry😔 Another Senior moment Red🤔
Think I'd better retire (again) when I hit 20,000 ranking points😁
Admiral Martin: stand ready to take over Fleet Command!
Cheers, Doug 😎

The same as the word gay. That had a totally different meaning when I was growing up in the 50's 60's and early 70's. Look how many songs the word gay was in and it didn't mean what we use it as today.

Looks more like Bad Robot to me - by the way Doug it was me not JB with the quote ...........

Damn Doug!,

you've not only spotted my long lost cousin floating above the ESC, you've likened me to one of my great heroes!
'Crip' is a self derogatory term that I use to confound people to state that in reality I am anything else- it gives me a laugh!
Andy

Sorry Fleet,
It's the madness in me, but i think i have it under control now.

"Doug, you are the same as me Totally Bonkers LOL!!!"
Careful you don't overstep your remit Admiral!😠
FLEET// 😎😁😜

"main cooler from an old failed Chromebook"
Excellent idea Andy👍
I've got 'dead' Dell laptop downstairs (long since forgotten the password anyway🤔).
Must have look inside it. I also have a few of the little mTroniks Marine ESCs.😊
Cheers, Doug 😎
BTW: Sounds like you have similar problems to the late great Stephen Hawking.
And no one would have ever dreamt of calling him a 'crip'!
PS Is that the ghost of ET drifting about over your ESC?😮

Close JB👍

Re "Mad" - my mother had a saying that ran rather like this - All the World am strange except Thee & I - and even Thee at times I fear - don't know where she got it from ............

I like that Andy, nice bit of recycling.

Martin555.

Just a quick follow up. This was a main cooler from an old failed Chromebook. Turned out to be perfect size to fit Viper marine esc onto. 5V supply from the onboard multi volt output board and the fan ducts cool air via a deck vent, through it's own metal duct. Heat sink and fan in one go - cost NOTHING!
Simple bit of recycling PC components

Andy

Redpmg, there is an upside to being a wheely person - we have a lot of time on our hands (not feet though!) Apple was named because Steve Jobs had just come back from an apple farm (he was into a weird fruit based diet at the time) and he thought the name was a bit cool, trendy and wouldn't be intimidating to new users- sort of cosy, cuddly almost.
So there you are and where's my application for 'who wants to be a millionaire' (I can still cough quite well, if required!)
Andy

I used to think I might be mad.
Then I looked in the mirror and it made me really mad!!!

Just drove the old legs outside for the family clapping of our amazing Health and Care staff. More and more people are joining in, even in the remote rural area I live in. We owe so much to so many. Personally, I'd like to say thanks again.
Andy

Re -How can you be so sure you didn't JB?
I can asu asu asure you Doug I'm compler compler comletely psane, nothing ro ro ro rong with me at all😀⛄🎁🎉💥🐱
JB (I think)

To solve your dilemma Doug, you are the same as me Totally Bonkers LOL!!!

Martin555.

"We used the UNIX system at work and looking back you wonder how you didn't go mad ( suppose we didn't know any better😁)"

How can you be so sure you didn't JB? 😁😉
😎

Thinks!🤓
I think I'm mad,😜
Or am I just mad at myself for even thinking that?🙄
Am I mad?😐
Or is it all 'the others' who are mad?😁
I think 'they' think I'm mad!🤔
That makes me mad!😠
I think I must be going mad☹️
Wonder if I can get a return ticket!😀
😂🤣😆

Hi Spock66,
I am totally Bonkers so you have a long way to catch up with me.
Just take a look at my build logs on the "Steampunk Pike" and "Evolution" and then tell me i am not LOL!!!!!!!!!!

Martin555.

Martin,
EXCUSE ME!
I'm mad and proud of it (or at least I think I'm mad, maybe it's the 'others'!!!)
Great we can share a laugh on here.
Andy

That is the reason why we are mad LOL!!!
Or is it just me ?

Martin555.

RE - Hate to say it but I must be really old
Wasn't it great Peter, when you could fit a couple of large photos or a tiny video on a floppy disc😂 (I still have a crate full of them which I had to transfer later to DVD. one at a time! I sort of miss the whirring and clicking😐😁 We used the UNIX system at work and looking back you wonder how you didn't go mad ( suppose we didn't know any better😁)

Re - The old water cooling rads and fans on those 486's, that we used to mod
My sons'machine is one he custom built from components and has some ridiculous TB capacity and power, hence the water cooling and all the fans . Plays games with guys all round the world. Cost him around $5k to build. I told him he could have bought a car for that! Makes my Pavilion 23 ( which is getting on now) look like a small laptop. He also bought one of those pressure sensitive drawing pads which is pretty cool and has done some amazing drawings on it. Wonder what's in the future?
Hadn't thought of the coolers for r/c use, not a bad idea !
JB

RE - Just had another thought about old printers.
They also have mini micro switches and dozens of nice tiny screws and springs. I don't throw mine out till I've stripped everything useful off them. Computers also have a lot of good bits, - rip the hard disc out and hang it on your fruit trees to scare the birds (flashes in the sun, - old DVDs are good for that also)
JB

Hi Spock,
I like you only learn enough to achieve a certain thing and by the time i need to do it again i have forgotten it.

For a guy using only one good hand you do amazing work.
Keep it up.

Martin555.

Hi Redpmg,
I agree with your comments, there are lots of us with limitations in any one area of our modelling lives. I am a non starter at turning, carving and fine rigging (to name a few). Not trying to be clever, or in any way smart, just trying to help a little. Youtube (as much as I dislike the interweb thingy, I am an older wrinkly), has some great starting point videos on just about any subject.
I taught myself as much as I needed to know to achieve a certain something and then tried it out. There were many false starts and burned out 'bits' but as it's all low voltage / current then all it cost was a few pence and try again.
So I really am sorry if I speak an 'alien' language, but there are, I'm sure, many electronic 'starters' like me and many more 'experts' in our group of modellers who could, I would hope, provide ways forward to each other in search of that little gem.
For me, for instance, I would love to work out a way of planking with the one good hand I still have. Then I could tackle HMS Victory, that I've always wanted to build in wood and if someone on our pages has a way, then I would gladly take any help on way forward.
Andy

Spock 66 - hate to say it but to us technophobes you could be talking alienspeak - know enough about electronics to avoid making battery connections the wrong way around - but that's about it. all those little electro thingys whizzing around make absolutely no sense to me at all - dont even understand Ohms law as some of the bits of it seem to be interchangeable......
I do understand what a pot is (variable resistor ?) but that's about the limit .
Sure there are a lot of others like me too..............

Hate to say it but I must be really old - the first PC's I dealt with were called Apricots (wonder where Apple came from) - you had to know your way around MS Dos to operate them. Came with a 12"? floppy disk which could be saved on in three ways MS Dos , Machine language and one I have forgotten. When you down loaded from the floppy - it was blank afterwards. Our IT Dept hailed it as a breakthrough from our mainframe as we could now prepare reports during the month instead of waiting for the printed month end reports from the mainframe.......except they forgot most items were not processed in real time (via punch cards) and most were only input once a month...........We also had a very primitive form of spreadsheet which had a nasty habit of when reaching its file size limit - disappeared for ever......
I always had 3 backup copies of my spreadsheets as I did the reporting to London for a very large International engineering company. I down loaded first copy - blank . Phoned IT dept - tech came running - inserts second copy to see what the problem was - blank - IT Head arrives AND before i could stop him inserts 3rd copy - blank - before realising there was something wrong with the PC . His face went white when I told him he had just deleted the last copy of an urgent report that needed to be sent to London that day...............The next thing I had the Group Financial Director in my office- to be closely followed by the Chairman/Group CEO
The result was the IT Head being dismissed NOT the technician - myself and the Group FD working 36 hours straight to recreate the report . We also lost all the Apricots (after using them for more than three years) being replaced by the then latest state of the art IBM PC's with a hard drive all of 30mb - the irony being that the IBM's were guaranteed for the users lifetime...........

Thanks Andy.
Good tip that with the wire👍 Hadn't taut o dat!😉
I've got a box of old printer gears which I'm struggling to make a 1to1 gearbox with.
I need it to drop the drive from the motor (converted Taycol Target) down to the prop shaft which sits real low in my ancient Danish fish cutter hull. Guess I'm not quite so good at making mechanical gubbinses!🤔
Not helped by having to work down inside an existing hull that I'm trying to convert from static to RC.
Cheers, Doug 😎

Hey JBKiwi,

The old water cooling rads and fans on those 486's, that we used to mod to get to the dizzying speeds of about a modern day alarm clock and the early pentiums/ amd alikes (yes I used to build them from scratch - shows my age!) are fantastic as coolers on ESC's that are running a bit hot - waterproof, sealed and electrically sound,with a nice low current draw.
Also if you interrupt the pipework, I can see a great bilge pump simulation just coming out the side of a larger scale model.
Andy

Just had another thought about old printers. It's beyond my ability for turning purposes, but for all you needing totally straight steel bar, either for use as is (bit big maybe!) of for turning down, there are 4 or more really good quality ones in most printers. So don't write of that old printer. round stock, good pieces of angle ali (or maybe steel ones) and motors, gears galore. Why should we not use a 'dead' item before we bin it?
Andy

When I first started working in the big CKD furniture manufacturing company here in Auckland, all they had in the drawing office was 386s. When we got the new 486s in 1990 it was like WOW, and when the first rendering programs were installed (up to 1 day to color a picture) we thought that was cool. The days of DOS and having to make your own spread sheets using formulae! deep joy!😁

I bought a Commodore for the boy to play games (on floppy disc) which he had fun on. He later went on to buy a maxed out special order Mac and now has built a huge machine with TBs of gaming power, 4 fans (with purple lights), water cooling radiator etc. Imagine giving todays' young'ns a 486 to work with!😁 - they couldn't handle the speed and go insane😂 Who would have thought back then computers would be cutting out model boats and full sized ships! and having 100x the power of a 90s computer in your pocket!.
JB

Doug,
No problem!
On the other side, if your old HP doesn't have anything useful, you could always remove the rotor - some great (depending on scale) rigging and antenna wires are to be found for free in these old motors, just unravel and years of supplies to be had. Some of the gears from printers are great for converting to windlass and anchor gear.
Andy

Fascinating Mr Spock!😉
I have an old HP 850 printer in the cellar and 555s and 556s comin' out me ears!
Hmmm! Thinks 💡
Oh no! Something else to fiddle with🤔
Cheers, Doug 😎

Hi All,
The concept that stepper motors need fancy controllers is not totally correct. They will happily turn continuously with only a 555 and a driver chip, a few off the shelf caps and resistors, LED to show rotation. All cheap and very simple. The speed can be controlled by a simple variable pot. I only say this because so many assume (not pointing this at anyone in this post, just a general observation) that steppers are complex and mysterious. The one advantage most steppers have over 'other' style motors is a very high torque and capability to withstand the rotation being stopped whilst under power. To try and assist the average user to make use of printer / steppers there are great resources on the web. I use Arduino and drivers to power a long redundant engraver (the control cabinet went u/s year ago) - now I have a functional engraver with dvd laser conversion ability to burn balsa wood - all for about £45.00 in motors and drivers (the mega expensive engraver was donated free from a company that had binned it due to the cabinet failure). Try this link for a simple demonstration http://diyprojects.eu/how-to-drive-stepper-motor-beginners-guide/#can-run-continuously

Obtained many years ago (80's) - secondary motor in a small printer - much smaller than the other - about the size of a 140 but shorter - have a lot of modern printer motors - unfortunately all stepper type which need a special controller............
Motor looks similar to the picture - Tug is only 13" overall

That is an excellent run time with the printer motor. Worthwhile looking into. My journey into rc model boats has all been about innovation.

LB that's the problem with the drill motors - very hungry for amps so short run times - would be much better to go brushless - more power - less amps - longer run times- even without Lipos

In the old days using a heavy draw 400 in my Avatar boat got good speed but only about 5 minutes good run time on Ni- Cad 7.2v pack. Using 480BB from Overland and 3300 NIMH 7.2v faster and far better run time. 8.4v pack cooked the ESC............

Prefer running the Lindberg tug - 5 AAA nicad cells ,7 pole printer motor (salvaged) - 1 to 1 1/2 hrs run time

Esc is a Sodil 320 amp forward 160 reverse, up to 16volt nimhi, or will take 4s lipo, maybe 60 amp running, run time on the twin pack nimh only about 7 mins but using a 55mm prop, will try some different props and lipos, you can hook up two 540s brushless with this esc, I have used the two + wires and the 2 _to hook up.
Graupner 700 brushed motors in my PT 109 and 34" Crash tender using this esc and lipo batteries give a huge boost in performance😁

Take it you were talking about "Mainframes" as they used to be called from the very early days before PCs John. Those would have been big motors - worked with mainframes for a while - most spectacular when they had a so called head crash - very noisy and usually costly.

LB you did not give the size of the RC truck esc - is it in the region of 60amp? Love to know what duration you get from the the two Nimh packs

Used lots I'll drill motors in the past with great success old style wire wound speed controllers 1960s/ 70s on 3ft + boats, latest is a 4ft glassfiber retired racing boat £15 off Ebay, I have fitted a 18vollt drill motor and a high spec rc truck speed esc, running two nimh 3 ,000 mah giving 14.4 volts.goes well but had the use of a test tank before going to the lake.👍

Do not worry about the servo motors they are from big old computers with 10 in plus discs .Real old stuff but the motors run as designed with no vibration at all. Put the ex drill motors on the bench with volt meter and ammeter in circuit and do some tests and comparisons .😉

That is interesting. My drill is a 20 year old hammer-drill and did not do a lot of work before batteries stopped charging. I guess the best thing is to get it attached to an ESC and see what happens. Am ordering a 60 amp esc which I hope will be compatible. I dumped two computer towers last weekend. Buggar

Some ex. drill motors have similar specs to commercial model boat motors . Particularly older cheaper drills. I remove the brass gear with a small puller. My 54 in Cervia Tug is powered by an Ex servo motor from a computer drive . No gearbox direct drive. 24 vdc motor but I run on 12 v lead gel cells.
No need to worry about weight , this type of boat requires a lot of ballast.😉

Newby
Good one! 😂
Joe

Maybe when he needs a hammer he uses the drill thinking it is a hammer drill.
Rick

"most had not done more than half a days work broke the gear box on most "
What the heck was he trying to do??? Hammer drill through reinforced concrete?
My oldest mini drill is nearly 40 years old and still going strong.
Strip down, clean and re-grease every few years and away we go again.😊
Cheers, Doug 😎

We had a chap come up to us at a show with an arm full of battery drills he said most had not done more than half a days work broke the gear box on most of them we found the motors were great in models and did not draw more than a normal 540 several of us used the chuck put a wooden handle on the spindle behind the chuck gives you a small hand drill for small drill bits

Motors - love that auto correct. Not.

Deans Marine has an excellent selection of motor and are very helpful.

Thanks again and sounds like a good idea. Will do that when on a 'real' computer and not the phone.

I have not had a powered boat in the past, only sail, so some advice from those currently having plenty of experience is welcome.
