Ever wanted to build your own tablet that can run Windows 10?

If so, I have some great news for you! In this instructable I will show you how you can make this tablet! This tablet is perfect for browsing, streaming video and other programs that don't require a powerful PC. I am personally using this tablet for browsing while doing different projects. The two usb ports can be used to connect a mouse and a keyboard, making it a laptop. Due to the thickness of the tablet, it can stand right up without any help so that is a nice bonus or a down side,depends on how you look at it! Tell me what other uses you could find for this tablet! I'd love to hear them

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Parts

2x 3W speakers 4ohm

1x Battery Charger

1x LattePanda(you can also go with the lattepanda alpha if you want to but I chose the 2gb model since I was on a budget)

1x Audio Amp

1x Waveshare 7" hdmin touchscreen screen

1x Flat hdmi cable

4x 18650 Cells

1x USB Hub with at least 2 USB ports

I recommend getting 2 flat hdmi cables since they are really fragile and you might break them.

You will also need:

-A soldering iron

-A hot glue gun

-Super Glue

-Wires

-A 3D printer(I use the Tevo Tarantula)

Step 2: Setting Up Everything in Sections

I am going to set up the tablet in sections, so it is easier to build the tablet. After we build all the sections, I am going to combine them all when placing them into the case.
This makes it easier to build since you don't have to worry about the messy wiring getting into the way. It also makes it easier to test thing which I do recomand.

After you assamble the battery,try to power the lattepanda with the battery. After you make the amp and hook it up to the speaker, test it out to make sure it works.

Step 3: Battery + BMS

I am going to solder the batteries in parallel and hook them up to the battery charger.

!!Make sure that the batteries have the same voltage!!
If the batteries have different voltages,they will discharge in one and another.
You should use a BMS(battery managment system) but I didn't have one at hand and didn't want to wait for the long shipping times that could take up to two months. I got lucky this time and the parts arrived in 2 weekes, setting a new record for the short shipping time.
Also, when soldering the wire to the batteries,make sure that the wire is thick enough and don't heat up the battery because you can damage the battery this way. Scuff up the surface of the battery before soldering to the battery.
I also covered the battery terminals with electrical tape so that nothing gets shorted with the batteries

Step 4: Speaker + Amp

I am going to hook up the amplifier to the speaker and solder a audio jack to the amplifier. The audio jack will plug into the lattepanda. I will also solder power wires and connect them to the battery with a switch in between. You can use another tipe of amplifier without the potentiometer because you can set the volume in windows alredy.

After you assambled it, you can try it out with your mobile phone.

Step 5: The USB Hub

I removed the electronics form the usb hub and also removed the usb ports so I can attach new ones to the side of the tablet. When soldering the wires,make sure that the wire is long enough to reach the usb ports in the case.

The usb hub is glued on top of the battery charger with a plastic in between.

Step 6: LattePanda+Screen

I am going to hook up the screen to the lattepanda and make sure that everything works.
I also cut the micro usb cable and solderd wires to the connector to save space inside the tablet.

Be careful with the ribbon cable of the hdmi cable because it is very thin and can break very easily. I orderd two hdmi cables but one of them was broken upon arrival. The store refunded the money

Step 7: Time to Mount Everything Inside of the Case

I am going to mount the screen in place with screws and guide the cable trough the top piece. Then I am going to glue the electronics part on top of the screen half. Then I am going to mount the electronics inside of the case.
The stl's are attached to this step. You will have to cut a hole on top of the hdmi port and micro usb for the cables. You will need to cover the hdmi and micro usb port's shielding so there are no shorts created since the LattePanda will sit on top of it. I wanted to solder wires to the button but it is a smd push button and the solder job is too hard and I did not want to risk damaging my board.

I've had some problems with my 3d printer and the screen part was not not printed perfectly. But after many failed attempts, I accepted it. Tried to sand it but didn't help much

I forgot to add a hole for the power button so I had to make one using the soldering iron and make a "L" shape to press the power button(image attached to this step)

This is the second version of this case, the old case was just one piece and I had to do a lot of modifications to it and in the end it looked ugly so I decided to re-design the case and print it again. If you watched the video, you might have seen that the case is gray. That was the old case!

Step 8: You Are Done!

That was it!

If I where ti build the tablet agian, here is whag I would do different:

-I wanted for the tablet to have a detachable keyboard but there was no room left at the bottom of the tablet for the pogo pins. You can cover the hole at the bottom with another piece of plastic or modify my design. If you can fit some pogo pins, you will need 6 pins(5V,gnd, and the other 4 for the usb connections). I wanted to use a keybaord designed for tablets and a trackpad that I took from a laptop and covert it to usb using an arduino leonardo.

-Use the screen designed for the latte panda since it doesn't have a hdmi and micro usb conector. These connectors added to the thickness of the tablet.

-Don't use 18650 cells since they are pretty heavy and bulky

-Desolder the USB, network, Gpio and audio jack. Pretty much every jack/connector and insted solder wires to it.

-Add a usb 3.0 to the side of the tablet beside the two usb 2.0 ports.

    Thanks, this was my biggest project so far and I had a lot of fun building it! Maybe I will visit it again and add more features to it!
