Thread: Garador door closer
14/09/2021 18:29:54

I have a similar problem on my garage door opener of a different make. I suspect that the problem on mine, and may be Peters, is that a current sensing resistor has gone a bit high. The control panel appears to be standard and the various settings are held in an EEPROM. Being like Peter I am reluctant to just pay for a replacement unit. I have got round my problem by bypassing the control unit with a push switch to manually open it. Closing can be done using the hand sets as normal. It's been like this for about six years now. It could probably be sorted by adjusting the values in the EEPROM by I haven't got a clue how to go about that.

How times have changed. Back in the late 1960s/early 70s I got done for doing more than 40 mph in an Escort van on an unrestricted section of the A1 dual carriageway. Enforcement was very strict then, fine and licence endorsement.

Grandpa gives his granddaughter a wristwatch. She shows it to her brother who asks "Does it tell the time?"
"No, Its old school - you have to look at it"

Thank you pgk. You have just made my day!

Thread: Ruggedising a Type 17 Stepper motor electrical connection
19/08/2021 12:06:41

I don't think there is much demand for end covers on NEMA 17 steppers as they are mainly used on 3D printers that don't operate in a particularly harsh environment. This is where the ability to design and 3D print something really comes into its own. I can't find any size 17 designs on the web that would fit to a motor that has a built in connector.

Seeing that batteries and therefore electric vehicles are Direct Current, how do they connect to a grid which is Alternating Current. Not only will the current have to be converted to AC it will have to be in phase as well

Roy

No Problem, this is exactly how a Solar PV sysytem works with a grid tied inverter. It changes the DC to AC and sychronises the frequency and phasing.

Thread: Problems in bending sheet aluminium to a 90 deg angle

Most DIY benders have the clampling angle "upside down" so that the two edges clamp the part and then there is room to over bend the part.

Would something like this be suitable? It's a toggle switch rather than a rocker, probably more robust.

I've had my solar panels for 10 years now and with the original high feed in tariff payments it's been a very good investment. BUT, like pgk, when you do the sums now it's very difficult to make the numbers add up. With next to no FIT nowadays the payback time based on what you save on energy from the grid is going to be very long. I would love to have battery storage for the approximately 55% I feed back to the grid but current costs make it a non starter.

Using an electric vehicle as the storage part of a system could be an option, me being retired, the car spends most of its time on the drive during the day so would be available when the generation is at its highest. I can't see me getting an EV in the near future though so most of this is just wishful thinking.

Even if it worked, as Oven Man doubts it would, it looks to me as if made from mild-steel, and would corrode quite rapidly despite what appears to be passivated zinc plating.

No. they are made of solid brass, they polish up beautifully. The thread is possibly a special as it is designed to screw into a fitting in place of the olive and tubing nut.

Thread: AA batteries

Anyone measuring batteries with calipers, insert a piece of writing paper between one end of battery and caliper,

then measure thickness of paper. deduct paper thickness from battery length.

This is not meant to be patronising in any way

I have found some batteries that vary in the same pack

Edited By roy entwistle on 27/07/2021 15:58:58

This is where a cheapo plastic vernier caliper comes in really useful.

The start of the Triathlon was an even bigger disaster. Half the competitors could not enter the water when the start horn went because there was a boat in the way.

I've got one of those in my pneumatics bits box.

It's designed for compressed air, I don't think it would be any good for steam.

Thread: Bench grinder
22/07/2021 22:08:05
Posted by duncan webster on 21/07/2021 22:31:51:

My el cheapo grinder vibrated quite badly, so I bought a new wheel with 1.25" hole and made new washers, the one nearest the motor has a boss to fit the in the wheel, just a bit shorter than the wheel so the other washer clamps up. this new thick boss/washer has 2 grub screws to hold it to the shaft. All unbalance problems gone away. I cribbed the idea off a RJH Ferret grinder

+1 for Duncans arrangement of integrated boss and flange. I did the same with very satisfactory results. I didn't use any grub screws, just the original outside flange and clampling nut. The major benefit of this arrangement is that the long hole, being a good fit on the spindle, holds the wheel nice and square and eliminates any wobble.

Thread: Mystery Desk Lamp

The 12v power for the lamp passes along the two metal bars which connect the lamp unit to the base unit.

Yes, the Ikea version that looks almost identical uses the two metal support rods. They are quite heavily varnished so so you might not get a reading if the multimeter probes are just touched on.

Thread: Best soldering iron for electronics
19/07/2021 10:37:45

Antex for me every time. Spares still available for a 50 year old iron, you won't get that with a Chinese one. I bought a temperature controlled iron from Lidl, it seemed to work OK but first time it tripped the house RCD it went in the bin. On opening it up there was hardly anything in the box and the electronics were extremely fragile. The device switching the current to the heater was the size of a small signal transistor, it did not inspire any confidence at all. Weller Irons are also worth considering, my instant heat soldering gun of that make is 55 years old, still going strong, and spare tips are still available.

The handheld hair dryers "lack an immersion protection device integral to the power cord," violating a federal safety rule, and thus "present a significant electric shock and electrocution hazard to users,"

Is this something that UK/EU hair dryers have? Never heard of it before.

What constantly amazes me is the wage train drivers seem to get.

Tony

Watch some of the you tube videos of train journeys from to cab view, and you begin to realise that train drivers really do earn their keep. It's 100% concentration all of the time. A dam site more stessfull than driving a road vehicle.
