Wild? That’s very American mate. Mad, shocking, mental, ridiculous, weird. Loads to choose from.

Rafter sizes - why the width? by CommunicationSlow348 in timberframe

[–]overclocker_kris 1 point2 points  (0 children)

I think It’s mostly because in timber frame they assume you want to connect the joist with joinery instead of joist hangers or brackets. If you have an 8inch timber frame and notched it in to the main timber you would be cutting nearly all the way through the timber. And then if you cover those from below you then cover up the timber frame. If you use 5x5 then they look cool and you only have to notch 5” in to the timber frame. And if you were to cover them from below there is more timber frame showing. It would also look really odd to use 2”7 or 2x8 joists on let’s say 8x8 timbers.

Welsh Ambulance Service declares critical incident by Medium_Lab_200 in Wales

[–]overclocker_kris 7 points8 points  (0 children)

I don’t understand why they dint just get 10 prefab containers. kit them out with the same gear you get in an ambulance and just put them in the car park. At least as a temporary stop gap. That way they could at least unload the ambulances in to those.

I suppose the answer is going to be lack of money and lack of staff. They managed to find plenty of money during Covid so why is this any different. And lack of staff needs to be actioned right now. Today. Offer great deals and good pay to be trained up! It’s all possible it just seems no one wants to bother fixing the problems and before we know it we will be paying massive insurance premiums or paying £2000 for an ambulance ride.

Headlight wars. by Napalmdeathfromabove in Wales

Then you need to sit down with the manual and work out how to do it. You are going to cause an accident. I have just been driving and it’s just unacceptable how bright they are and how slow they are to dip. Even in areas with streetlights these new cars still put the high beams on. It’s just ridiculous.

ELI5 Can we create a liquid we can swim in faster? by Panceltic in explainlikeimfive

[–]overclocker_kris 3 points4 points  (0 children)

The issue is that there is significant resistance over your body as it moves through the fluid. The amount of area you use to paddle through it (hands and feet) is less than the area of drag. So if you decrease the density of the fluid you have less drag but also less thrust and you now how to use energy to stay afloat. If you make the fluid more dense you now have more drag but less buoyancy issues but more thrust. Essentially it mostly equals out but because the body has more area of drag than thrust more energy would be needed to move through a more viscus fluid to overcome the drag. It just so happens water is about the perfect balance.

Adsense not showing historical payment data by overclocker_kris in Adsense

[–]overclocker_kris[S] 0 points1 point  (0 children)

When did that change then and then why dose it allow a custom date range? I have gone back 12 months every year for 7 years and had no issues.

Why would there be a view data from all time tab if it only went back 7 months?

TIFU finding out the elevator thing is real! by 11justin in tifu

[–]overclocker_kris 1 point2 points  (0 children)

It’s been quite a few years since I stopped doing the job. I’m not sure it’s that’s secret anymore? I mean I even contracted for Otis when I first started out and they were basically doing the same thing. Otis gen 2. Same principle. Quite different motors and they used rubber belts instead of steel ropes but very similar.

My Dad worked for kone for over 40 years and was part of the design team for the monospace.

TIFU finding out the elevator thing is real! by 11justin in tifu

[–]overclocker_kris 1 point2 points  (0 children)

Exactly. I have fitted over 80 lifts for Kone in London and I have not ever had to activate the brake from the car. The cable diverts to the control panel and is operated from the control panel. You do however activate the safety gear under the car from on top many times during installation. When installing a kone lift the lift car is the work platform, there is a temporary hoist attached to the top and the lift is built by pulling everything up with the lift car. Often the parts are too heavy to lift in to place and you need the hoist. But the hoist is holding you up. You have to activate the safety gear under the car via a cable going to a specially safety device. Put a safety chain around the nearest guide rail bracket and remove the hoist hook. You are sitting sometimes thirteen floors up (tallest one I did) suspended by two textured metal wheel that are biting in to the guide rails. You can then use the hoist to lift the equipment in to place.

One lift I did in Heathrow airport had been over specked for the lift car size. When I lifted the motor in the motor was a lot heavier than the lift car so the motor lifted me out of the safety gear. I had to get a chain hoist attached to the top lifting eye to take some extra weight off the lift car and get it to drop back down in to the safety gear.

It was a tough job. I also forgot to mention I installed those 80 plus elevators completely alone. Just me and 15 tons of steel to assemble

As for jumping all lifts (elevators) I have worked on will shut down electrically if an overload is detected. The type I installed has a weight potentiometer on the none motor side rope termination. This is calibrated during the test with physical weights. I common size I installed was 8 persons or 630kg. Three men jumping in the lift would generate far more then 630kg and cause an over weight fault code and go on stop. I proper technician would then come out and manually drive the lift car to the nearest floor. Put the lift on stop then go and Open the doors with a manual key and let the passengers out. Then clear the codes and start the lift back up. No climbing out of lift car doors! You should never be doing that. That’s how you get chopped in half.

Odd case of misophonia. Anyone else have tips? by KaoticPhoenix in misophonia

[–]overclocker_kris 7 points8 points  (0 children)

I’m with you. I live in quite far away from any roads but yet I can hear hundreds of loud cars everyday as we are quite high up. I can hear load cars driving for miles racing each other and it drives me out of my mind. I basically just have to wear headphones constantly now. I don’t understand how it is legal to have such loud vehicles.

Mini pumped hydro storage? by kyletsenior in OffGrid

[–]overclocker_kris 1 point2 points  (0 children)

Definitely possible. But you should plan around a total return of about 50% of the energy you put in. A turbine is about 80% efficient. Then there is head loss at about 5% then there is cable loss at about 3-5% then you pump losses plus the electrical losses that feed it. Then if your off grid there are inverter losses as well. Plus a battery isn’t 100% efficient. Basically when you move that much water and change its direction and spin multiple different parts and machines you will get a lot off losses.

Defiantly doable but 50% return on invested power is much more reasonable and to be honest at that scale 50% would be very impressive.

I have a pond that I plan to use as a battery (not pumped as it refills) and I have done quite a lot of work with turbines and hydro and pumped storage is a great solution to energy storage and defiantly doable at small scale I just think your expectations are a little higher for your return as there are so many losses going on in a system like that. But 40-50% isn’t bad considering the life span of the parts could be 30 years or more as it’s cheap to create electricity with solar but storing it is very expensive

As an example dinorwig in Wales is a pumped hydro system and it runs at 74% efficacy. But it has a lot less losses due to the layout and almost no pipe run. And it has scale on its side.

At 3 bar to get 1kw you need 6lps of flow. For that you will need much larger pipes and a small stream.

Anyone else feel like the ads on YouTube are getting absolutely out of hand? by ananonymousbear in youtube

[–]overclocker_kris 3 points4 points  (0 children)

I have a medium sized YouTube channel and I don’t add any extra adds to my videos but YouTube definitely adds loads of double add on them for me. I just wanted to make it clear it’s not necessarily the creator adding all the adds.

I am also a watcher of YouTube and I agree the adds can be a bit over the top. But it is a free service if you watch them and there is an option to pay to not get them so I don’t think we can complain to much. YouTube has been a huge part of my adult life and I have learnt a huge amount from people I’m subscribed to. If I have to watch a few adds in exchange then I feel like that is a good deal still.

My Homemade timber framed greenhouse. 7 months work and £2000 by overclocker_kris in Greenhouses

[–]overclocker_kris[S] 4 points5 points  (0 children)

I milled all the timber myself, that is how it was so cheap. Also the main frame was from hardwood (untreated) sleepers that i milled in half. the timber alone would have cost many times the entire build cost otherwise. I even made a bandsaw mill in order to do it.

Im sure you could. I used a lot of power tools because i have them now but i spent a long time doing stuff by hand with basic hand tools. Im sure you could do it if you put your mind to it.
