TFTP setup and install OpenWrt on RAVPower FileHub RP-WD03 Portable Router

The RavPower RP-WD03 is a fantastic little device incorporating a Wireless AP, File server, SD, USB charger and even has an ethernet port! But for me it could be so much more, to unlock its full potential we look to OpenWrt. OpenWrt is an open-source firmware designed for just about any router that will accept it and there are ofton different methods for installing OpenWrt to routers, some can be very invasive but this video is about the TFTP method which is very easy to do.

TFTP stands for Trivial File Transfer Protocol, and sending our firmware file to this little router shall be trivial, by default our router has an inbuilt repair system, no matter what happens (within reason) if you boot the router and hold the reset pin it will always look for a TFTP server and then download a file called “kernel” if it finds this file it will always install it over its system.

This safety feature is designed to be used with the stock firmware to repair it if has become corrupted or any other fault but we use this to our advantage! Instead of the “kernel” file being stock we use the OpenWrt firmware image and rename it, when the RavPower boots it downloads and installs the firmware like its own! Viola a perfect running OpenWrt router!

The disadvantage to OpenWrt on the RavPower RP-WD03 is the memory onboard, with the firmware installed we are left with very little space for any extra software. However, we can overcome this quite easily with an SD card. With an SD installed we can mount it and use it as our main flash, we are planning to make a video in the future on how to do this so make sure you subscribe and leave us a comment if you’re interested!

Beginners Guide to Lock picking and raking

We made this simple guide to help those starting out in lock picking and locksport. When I first started to learn to pick locks I assumed one method fits all and thought that the slow method of picking individual pins was the only tool available to lockpickers, I found out that in fact there are many ways to pick a lock, and one of my other favourites is Raking.

In the video, I start by showing the more well know method and then move on to raking. It can be great to practice with a perspex lock so you can really understand how the lock works, also try not to limit yourself to using the same picks all the time, different picks have different advantages to locks so try to give them all a chance!

Once you’ve mastered these techniques you can move on to more complicated locks and methods, In the future, we will make a video about the Kronos a powerful tool that can automate and speed up the raking process! Make sure you Subscribe for that one.

Delid and apply Liquid Metal guide for Intel CPU’s

Delidding your CPU can be a great way to improve its effeciency and and improve its ability to get heat away from the die. A CPU is only as good as its temperature and depending on your CPU it will throttle at higher temperatures to try to protect itself from over heating and causing damage. When you connect your cooler to your CPU thats really only half the story because no matter what thermal paste you put between your IHS (lid of CPU) and your cooler you will limited by the amount of heat that can be tranfered to the IHS from the Die (The main chip) by the compound between these surfaces.

In most Intel desktop CPU’s you will find an average at best thermal paste between the Die and IHS so this can be very limiting if you are trying to push your CPU to higher limits perhaps with overclocking, gaming or rendering. In my own experience, I have an intel 7700K overclocked to 5Ghz and though I have water cooling and 2x 360 radiators I could never get my temperatures stable until I decided the CPU and replaced the thermal compound with liquid metal, not only are the temperatures more stable the CPU runs at approx 15 degrees cooler.

However, Delidding definitely isn’t for everyone. It’s a very dangerous task and in the worse case, you could destroy your CPU and will definitely void any warranty you have. You cannot rush it and you CPU will be out of action for 24hrs while you let the silicone dry so keep these things in mind.

I’m suggesting liquid metal as our heat transfer compound because it will give the greatest amount of thermal transfer compared to pastes, however, liquid metal as you would expect is conductive and so you do run extra risks by using it of shorting components. I will show you how to combat this in the video but it is always a risk. Liquid metal will also react with Aluminum so if your IHS is Aluminium use something else. If the risk of liquid metal is too great for you you could use the exact same process with thermal paste, without the need to spread it atop the Die and IHS.
