Neutral color LED headlamp
I generally find that unless I'm building a new PC from scratch, I'm having to work in less than ideal conditions. No matter whether I'm repairing a PC, fixing a network cable, or diagnosing some other random problem I'm always struggling to get light on what I'm doing.
For a few years now I've been relying on LED flashlights and headlamps. They offer a powerful light and last a very long time. But they have one drawback — the light the LEDs give off has a blue cast and this can make it hard to identify colors. This isn't a problem when dealing with screws and such, but when I'm dealing with cabling or wiring, it can sometimes be challenging to tell some colors apart.
This is why I've made the switch to the ArmyTek Wizard Pro XM-L2 Warm. This ticks all the boxes for me:
Very variable light output — From a firefly more to one that feels like "Superman's laser beam melt your face off" mode
Choice of batteries — I can either use two disposable CR123A lithium cells or one 18650 lithium-ion rechargeable cell
It's hard anodized to take bumps and knocks
The LED color output is a neutral 4000K which means colors look far more normal
It features an impact-resistant glass lens with sapphire with anti-reflection coating
The supplied headband is comfortable
Price: $99.95.
PSU tester
Sure, you can spend big money on a PSU tester, but for confirming a dead PSU I find a cheap tester is handy. Also, if you have a few hard drives handy, you can add some load to the PSU by connecting them up before you test. My go-to device is the FrozenCPU tester. It's cheap but reliable and does what is says on the tin and not bad value for a little over $20.
If you want to take power troubleshooting to the next level then you can get your hands on a decent multimeter. If it's something you're going to use occasionally then a cheap one will do fine, but if you want something that will last you years then I'd go with the Fluke brand.
Broken/chewed up screw remover
It's a crazy name for a fantastic tool that can grip screw heads, bolts, or nuts allowing you to twist out even the most damaged fasteners. It might seem steep for $30, but it's a real lifesaver.
