It would just be a pic of a led strip . Like this.

My son's father in law has five of those lights from a cut up strip light in each room of his house all coupled to a battery in a cupboard that is charged often. They are on a switch. He turns then on during night power failures and apparently you can see throughout the house. Never seen them working.
Great idea.

That's an awesome idea. I have a short strip that I might for that with. I was actually holding off on that idea, but now I'm sold.

If you live near Roodepoort. At Hillfox where Metro cash and Carry was, about the 4th shop theres a oke that sell them for almost nothing

Editor's Note: This was 6 months ago. I cant confirm if the relevant Flea Shop Owner still trades in said LED light.

Just make sure that they are 5V if you are using a power bank

After a weekend of redesigns and improvements I have arrived at Dremel homogenizer V2. Frankly a 200mm long 3mm dia shaft was ambitious to say the least.
I discovered a 3mm ID bearing is exactly that, but a M3 threaded rod varies from 2.5 to 2.85mm and that contributed to shaft whip even with another bearing in the middle.
The only way to get everything concentric was the lathe, my 3D printer isnt the most accurate producer of results.
I found the top hole introduced too much air and blocking it off increased the flow through the bottom one, which is what I wanted to lube the bottom bearing.

Tesla style head made from delrin.

No matter how long you stir oil and water on the mag plate, they dont mix.

Enter the Dremel and some serious mixing takes place, this after 2min and no separation after 2 hrs, just some layering.

I found speed 4 on my Dremel worked the best and at 8 the output from the discharge holes was noticeably reduced.
Edit: this was for the oil water mix, ejuice is considerably thicker and loads the motor more, so I cut a disc off the 4 disc rotor which should help reduce the strain on the Dremel.

In closing, if you can afford Nico Lubbe's pro version that @KZOR demo'ed, go for it, its def's a game changer for mixing and if you can, maybe ask for a custom tesla turbine style head.

Nice upgrade's bro. Well probably be seeing V3 soon. Keep it up!

At last got round to fixing the sagging paving behind the pool. Then ran out of cement. Next weekend, more of the same.

Sun fried me and mixing cement broke that which was not already painful from working on my knees.

Big project. Luckily I have old age and a messed back as an excuse not to do big jobs like that anymore.

Not the weekend yet but this has been bothering me for a long time. My main pulsar was still working but the button had lost its click sound.

Original button.

After removing the original button and preparing the surface with solder paste.

Final pic with new button before cleaning the surface.

pleased to say the click is back and the button is working again

Iron. I wanted to get a rework station but the amount of soldering I do doesn’t warrant the cost!

I'm in the same boat,but have to replace my iron soon and fit a reostat.

Look at the magnum range. I have one where I can change the tips and a small potentiometer to change the heat settings depending on the application required.

That's a lot of ching for a soldering iron! But then again, I solder very very very little. I have a 100w Topline jobby

I need interchangeable tips depending on the size of the component etc. R500 is still better than R5000 and I really want a weller but let’s not talk about those prices!

If you are using a tool often enough, one can always justify the costs. Currently looking at getting myself a R2k 3-chisel set for my woodwork hobby

Bro what do you want to do with the chisel set?

I was saving to buy a hammer. Every month I came to the shop with the cash, the price increased.
I eventually screwed that idea.

I needed a scarce weight of 28oz. Not a size needed alot.

They can keep their hammer.

How many times have you used a spanner when in a pinch?

Anything can be a hammer if you need it to be... And if you can't fix it with a hammer, it's an electrical problem.
