The two watt rating of the (any) pot is across the whole pot. Turn it half way and it's half that rating. Careful of that when you start turning it down to a low value. Another way of looking at it is the power dissipation has to do with the surface area of the resistor section in use. When the whole resistor element is used it can dissipate (cool) the whole two watts. If you're only using a tiny sliver of the element it can not cool off as easily.
Ian - I picture you on planes chasing pixies and making sure we are all safe in the air... :) hopefully we will get back to normal soon.. Cheers mate.... J
🤣 Hope so Johnny...some of my younger pals (early 40’s) are getting laid off now...They all have young families. Tough to endure. Still, we hope for better soon! Cheers Pal 👍
Clever boy well done
Dirt simple. But might be handy...Cheers Ian 👍
Great tool. Would you be so kind to share the link to purchase one of these potensiometer
Just search “5K multiturn” on amazon...you’ll find it. Thx for watching 👍
You need to get the DS1000 patterned my friend , nice handy tool 👍👏
💰💰💰🤣 Cheers Igor 👍
Thats a great wee box now
I am glad it’s built on dollar store rubbish Dave. It encourages endless modification. Will build it right on of these days...maybe 🤣
decade box is a mix of 1/4w and 1/2w resistors (I think)
the POT is 2w ... that alone can sell me on this
Great alternative, Ian
Hi Denis. When I purchase the decade box it was advertised as 1/2W...I tell you what. Smallest 1/2W resistors I ever did see 🤣 Cheers Pal 👍

@@davesage9190 Good point. Never considered that to be honest. Thx for watching. Cheers 👍
Great video
Thx Boss 👍

Yeah, Johnny...one the hardest hit industries in this mess!
@@theGADGETSplaylist yeah mate...its a mess but hopefully back to normal in < 6 months... 😁
