Need help/advice for improving a LED light setup
5 more posts in this thread. [Missing image file: ]
I recently got my hands on a light-kit for a project, and looking over the design of it I fell like I should be able to improve upon, which is why I'm asking for help here on DIY. The kit is made up of:
1- 45cm/18" LED strip
1- 62cm/24" SMD strip
2- 2 position slider switches
Both of them run off individual N-type battery holders using A23 12volt batteries. I've been stumped trying to find answers to my questions about improving the functionality of the kit, as well as something specific about one of the strips so heres what I'm curious about:
1. Is it possible to wire the two strips to one power-source?
2. Is there a 4-mode switch out there, which will allow me to turn the individual strips on, as well as both at the same time?
3. In the picture you'll notice I've circled a section of the strip, is it possible to cut the strip without compromising it so it doesn't hang over like it does?
Thanks in advance for any all and all advice.

I sell cupcakes and other sweets in events as a hobby to pay my other hobbies.
Recently I devised and built a luminous box/display to hang on my neck to advertise whatever I'm selling. It works pretty much like intended, the only problems I've faced so far are:
1. The battery is fucking heavy on my shoulder, tho I guess there's no way around this and the tendency is to get even heavier the better the battery is.
2. Even though I've hooked it to a simple 1.2m led strip, the charge drains away so effing fast! I mean, it's just a simple led strip, I was hoping for at least 7 hours. Also, the potency goes down some good 30~40% after the first 30 minutes and then stays at 70~60% for two and a half more hours before fading too much.
So, any ideas? Maybe I could change the design of the strap a little to better distribute the weight and/or use one more battery or something. What do you guys think?
Picture is the current design info.

Any welders in here?
Have been asked to do some 2.6mm CDS, I mostly just do thin sheet ~ 1mm so this is new to me.
I'm struggling to get decent penetration as far as I can see, there is no colour change in the metal that i'd be used to due to the heat, and the beads generally seem to sit on to of the material, and not puddle up.
Is this a limitation of my machine? On the box it says it can do up to 5mm, but i've never tried it.
My machine is 135amp, using 100% CO2, 0.8mm wire.

Hey /diy/, /ck/ here. I've been having fridge problems (Whirlpool fridge Model#ET18NK) lately (water leaking from freezer into fridge and then pooling and filling up crisper drawers). I unscrewed and took out the bottom panel of the freezer and found a BUNCH of ice and could see that the drain hole in the far back of the freezer was also frozen. I chipped off and removed all the ice that was covering the bottom and the drain hole in back and came back this morning to see that most of it had came back.
I understand that this probably means that somewhere down that drain line is still frozen and the water just builds up and freezes again, eventually allowing some to drip into the fridge through these two parts (pic related), they are made of Styrofoam and cover two holes that lead down into the fridge, these tunnels are also lined in Styrofoam.
SO I come here asking two questions, and before you ask I HAVE done some googling but everything is rather vague on what I should be doing (not to mention dated). How can I fix this/what can I do to determine the problem? AND what are these two styrofoam triangles for? The fridge was in the house when we moved in, did they just forget to take out some packaging? As you can see I broke one while pulling out the tray (they had frozen together). Thanks /diy/ you are my only hope.

My brother recently got an air compressor free from a neighbor who was moving. The guy used it semi-frequently, it runs, safety features work, etc.. My question is how long should they last? The date stamped on it is 1998, and we don't know how well it was taken care of (the guy was kind of a dolt), but the thing looks like it was drained sometimes (by the PLIER MARKS on the plug). I took the plug out and a bit of gray shit came out with some moisture. When it dried it was like clay, and a magnet picked it up. Can't get a good look inside.. Worth using it or prob too old/corroded? I'd like to keep my limbs.

Bicycle brake cables

I'm fixing up an old Puch bicycle, and I've hit a problem while installing new brake cables - The handlebars are straight, aka MTB style, so I bought mtb brake cables (the kind with barrel ends instead of pear shaped ends). That's the same kind as I took out, which I've since thrown away.
My problem is that I can't push them into the handles. Do they come in different sizes, is it because it's vintage and/or European? Am I doing something wrong? Attached is the empty handle, following is how far into the handle I can push it.
