A DIY tablet basically consists of 3 main things. A tiny computer, a touchscreen and a battery pack. Do note that all shipping costs are from the country of origin to Singapore, so costs might vary based on where you live.

A. Korea

You'll need to pick up the following things from this site: Hardkernel

1. Odroid U3 - USD65 - The tiny computer

2. RTC Backup battery - USD2.50 - Maintain system clock

3. Odroid U3 case - USD4 - for good measure

4. USB DC plug cable 2.5mm (at least 2 units!) - 2X USD1.9 - Used to connect the Odroid and the touchscreen to the battery pack. Difficult to find elsewhere.

5. WiFi Module 4 - USD14

6. 8GB SD/eMMC module U Android - USD8/USD25 - Whichever fits your wallet and attention span, eMMC is much much faster than SD. You could use your own SD card, but remember that 8GB is the minimum. Also, feel free to buy one that has a greater size if you want.

7. HDMI Cable(Micro, type D) - USD5.70

8. Shipping - USD30

B. Malaysia

The next place you'll need to visit is here: Chalkboard Electronics

1. 10" universal LCD with HDMI interface and capacitive multi-touch - USD134.95 - This module is unique as it requires a 5V power supply, whereas most others require 12V. This allows the board to be powered up by about any standard battery pack. Do note you can also buy the 7" option if you want, but not the 14" and 15.6" versions as they require 5.5V. Do also note that out of the box, single touch is supported and if you want multi touch, you will have to update the firmware and kernel as described in the chalkboard electronic blog.

2. Shipping - USD33.60

C. Your local electronics store

If you live in Singapore, I got all my stuff from the infamous Sim Lim Square.

1. HDMI type A to type C converter - SGD5/USD3.62 - The Chalkboard electronics Screen receives a type C HDMI input.

2. USB male to USB mini male - SGD3/USD2.17 - The Chalkboard electronics board uses a USB mini input from the Odroid to get touchscreen data.

3. 12,000mAh Battery pack with dual charging ports - SGD19/USD13.77 - The power supply for the tablet. The dual ports are needed to simultaneously power the Odroid and the Chalkboard electronics Screen via the USB-DC plug cable from Korea. Do note that some power banks cut power off when the Odroid and screen are plugged in (too much current drawn), so the best way to check is to bring the Odroid and screen down to the electronics store and test it in store.
