Using the Hidizs AP80 as a Micro SD reader

Using the Hidizs AP80 as a Micro SD reader

Hi everyone,

It comes a time when I have to update my Windows devices manually because sometimes, on my Intel Atom machines, Windows Update fails to install a Windows Insider build. I know I’m not the only one who have had this happened. One thing one can do to solve this is to go ahead and download a Windows Insider ISO and then create a bootable micro SD card, with tools like Rufus. Now, the bootable part is not important, as I’m upgrading my Windows install rather than doing a clean install.

I used an 8gb MicroSD card that I have and used Rufus on my AMD Ryzen desktop machine. I then used my Hidizs AP80 in USB Storage mode to make the microSD card appear in the PC and format and prepare the card with the ISO. Once that was ready, I used the Hidizs USB-C to Micro USB cable that came with my Hidizs DH1000 (the Hidizs AP80 also comes with this cable) to connect the USB-C port of the AP80 to the Micro USB port of the tablet. From there, I was able to go to “This PC” -> The Micro SD card and launch the Windows 10 setup to begin upgrading my tablet. It is really nice that the Hiby OS that this DAP use has different modes when it comes to USB, because you can either use it as a Storage device or as a DAC.

Here’s the image where I have my AP80 connected to my tablet:

Hi everyone,

In this post, I’d like to show you a series of photos unboxing the HP OfficeJet 4650 printer.

This is a very nice printer. It’s cheap, and offers office-quality printing. I purchased it at Best Buy.

Let’s begin!

The box:

Here’s the front of the box:

There are the manuals, ink and power cable.

After taking all of that off, we can see the printer:

Solving the HP Stream tablets CPU Throttling

Solving the HP Stream tablets CPU Throttling

Hi everyone,

In this post, I’m gonna talk about the HP Stream tablets and how to work around the overheating issues you may have with them.

These tablets works really good most of the time, that is, as long as you are in a well ventilated room, or a room with Air Conditioner. However, on tropical weather, it does not performs good sometimes. This is because the temperature is mostly in the mid 70s to 90s F, and in the summer, it can reach 100 F or more, and this causes the tablet to overheat and therefore, the CPU starts to throttle.

The tablet has a Quad-Core Intel Atom Z3735G clocked at 1.33Ghz. However, the CPU can reach up to 1.57Ghz given the CPU temperature is not extremely hot.

Now, the other issue is that the tablet is mostly plastic, and plastic is not a good heat conductor as compared with metal, but also, it is good that it is plastic as it would not transfer the heat to the battery and it is therefore concentrated in the CPU area, which prevents damage to the battery as the battery is kept cool. If it were metal, the heat could easily transfer to the battery and this could result in the battery getting swollen due to heat. So, each, plastic and metal has its pros and cons.

As you may know from the other posts I’ve made, I run the Berkeley Open Infrastructure for Network Computing (BOINC) in my PCs, and these tablets are no exception, but given the overheating issue, I had to find a solution to keep them cool.

HP Stream 7 and 8 crunching BOINC Tasks

Mainly, when it runs a BOINC CPU project, the throttle will not be severe in most cases, but when you add a GPU project to crunch, then that’s when the tablet will throttle severe enough to make it unresponsive until it cools down and the CPU clock restores to more than 1Ghz.

So, what is a good way to prevent the tablets from overheating and throttling? I got some aluminum heatsink that are designed to keep products like the Raspberry Pi cool. These aluminum heatsink comes with a thermal conductive tape and it is a good way to dissipate heat from the device.

Once the aluminum heatsink arrived, I attached them to the HP Stream 8 tablet, and then to the HP Stream 7. Below, you’ll find the procedure I made:

First, we must take the back panel off and remove some + screws. It is very easy to remove, and once removed, we will see the printed circuit board:

HP Stream 7 and 8 Heatsink Mod 1

The area we need to cool is this:

HP Stream 7 and 8 Heatsink Mod 2

We need to place the Thermal Conductive Tape to the heatsinks:

Now, we just place it in the area we need to keep cool:

HP Stream 7 and 8 Heatsink Mod 5

Of course, one heatsink is not sufficient, so we will be adding more (The item I purchased came with 10, so I installed 5 per tablet):

Now that we have applied the heatsinks, we need to make a cut to the cover so that we can reapply it to the tablet to protect the circuit board:

And that’s basically it! The tablet will not throttle unless the heat is sever enough. Now, a little fan to keep them cool really helps.

Now, I can run SETI@Home in the GPU of the tablet without it throttling.

Hi everyone,

In this video, I will be unboxing the HP Stream 8 tablet. This tablet has basically the same specs as the HP Stream 7 I showed you yesterday, as it comes with an Intel Atom Z3735G @ 1.33Ghz, 1GB of RAM, 32GB of eMMC storage, Wifi/Bluetooth connectivity, and it came with Windows 8.1 but is fully compatible with Windows 10. The main difference between the HP Stream 7 and HP Stream 8 is that the HP Stream 8 is 8 inches while the HP Stream 7 is 7 inches. Also, the HP Stream 8 comes with an HSPA Modem so you can use the internet whenever you go as long as you’re subscribed to a Wireless Carrier Data Plan. The tablet came with a T-Mobile SIM Card which offered 200MB of free data every month, but for just $10, I could add 5GB of High-Speed Data and then it would throttle to 128kbit/s, which is a very good deal considering that music data doesn’t count the High-Speed Data Allotment.

The tablet itself is actually good for lightweight tasks, however, like the HP Stream 7, the 1GB of RAM is pretty much the limiting factor as Windows 10 uses some 800MB most of the time out of the 1GB available, so it uses the Page File frequently, making the performance of it a little slow sometimes. What I like most about this tablet is having Windows 10 in it and using the internet whenever I go.
