Re: poorly computer

Strange but true ! After few years of constant performance, my PC now fails to pickup the system disc! Just offers options to continue via a number of choices all of which all work. If you believe all you read, this problem MAY occur after a MSoft upgrade. Why am I not surprised ? Following geek adv...

Re: poorly computer

Just a passing thought, how old is the hard disc ? It might pay to run a check on it for failing sectors. Although reformatting the disc before loading the operating system should solve the older bad sectors. Freebie checkers are on the web from most hard disc manufacturers. Plan B. Replace the disc...

Re: 12v LED strips. Old 2amp dc transformer

Thanks for the links, personal recommendation always welcome.

Last time I had anything to do with electronics was soldering wires in chassis with valve bases! So my description of modern bits n bobs are a bit vague :roll:

El84 and El83 valves seem to ring a distant bell.

Re: 12v LED strips. Old 2amp dc transformer

Thanks for your replies, I left it a while just in case anyone else joined in. I think I'll play around with the old DC supply and Buck bits to see how things work out. I am after about 10v and 3 volts for lights. The Supplies from the internet generally seem to be above those values so would need a...

12v LED strips. Old 2amp dc transformer

I am using some cut 12v led strips (3 leds per strip) for model building lighting. All tests with a 9 volt battery seem to work ok and give a suitably bright light. So I am thinking of using an old dc supply (I have a feeling came from an early scalelectrix set as the power source running through a ...

Re: Mini saws

Just to report back on my mini saw. For good or bad :roll: I continued my plunge cutting of supporting piers for the upper track. I plunge cut the main runs and finished to the corners with a jig saw. Once I had the blanks marked , it took about 30 mins to finish 20 piers. The saw is very easy to us...

Re: Soldering steel rail.

From your description, my feeling is the same as yours, the bit is loosing heat quickly, and not being replaced fast enough to maintain a working temperature. A lower temperature solder might help. If you take a look at Rapid on line , the range of solders melt temperatures range from 180 to 240 Deg...

Re: Ballast

I seem to recall from another forum that pumice can be purchased in a garden centre and used. (Bonsai, hydroponics, general surface dressing) It’s lightweight, cheap, easily broken down with a hammer, washable to remove dust through a sieve and glueable with pva glue. I might give it try when I get ...

Re: Mini saws

Might be useful to investigate a small band saw. You an get fine blades for wood plastic or light metals. Very thin / narrow blades for tight curves. Although it can get exciting if you go to tight a bend. Some also have a Velcro based disc sander incorporated Heavier blades for thicker wood. Depth ...

Re: Mini saws

if I was starting afresh, I would have used timber and improve my carpentry skills. I started with a hole cutter but it was a bit of a challenge because the cutter was losing it’s edge. I was making do with what I had in the shed, so came up with rectangular cut outs. Eventually you have to use what...
