If I ask about how to build a libre software mainboard into the cabinet of a common notebook, lkcl gets rather hectic on rebuffing such option. Some of his arguments I accept. Others I do not. One lkcl argument is, I should not spend thousands of usd on making an attempt with an uncertain outcome. I agree on that. For now I have spent 50usd on getting an asus 7inch eeepc. I like the size of it. It has a full keyboard. It is bulky. Therefore more likely to have space for building in another mainboard. Lkcl says, should I succeed in building one, only I would benefit. I disagree. I would tell others how to make a similar computer, should they want to. Then lkcl has this argument about reverse engineering a lot of computer devices. I do not understand it. Apart from the display all devices should be usb. Sound, touchpad, keyboard, ethernet, wifi, storage. Display should be hdmi. Rather I believe getting a battery and powersupply solution would be difficult. I would also like to make a libre software computer looking like the pocketchip. I have bought this generic 6usd keyboard. https://images-na.ssl-images-amazon.com/images/I/51q2r5Jvu2L.jpg I do not like the feel of the keys. Apart from that it is adequate sized. The keyboard does not work via usb wire. It would require the keyboard to get modified. > Keyboards are invariably a passive switch matrix (look it up if you don't > know About the asus eeepc's keyboard. I have. I am not clever enough. Lowpriced on ebay I found an ATMEGA328P-PU Microcontroller. A GPIO kit Extension Board Adapter Breadboard. A flat cable Ribbon connector socket 30pin 1.0mm Pitch. Apparently using a raspberry pi, you should be able to program the microcontroller. How to make the keyboard's matrix, I do not know. > Touchpads are almost always either USB or PS/2 What I have been told. > It's the screen and battery interfaces that are going to get you This rk3399 mainboard https://www.cnx-software.com/2016/12/05/firefly-rk3399-rockchip-rk3399-development-board-launched-on-kickstarter-for-139-and-up/ has a hdmi port. What should be the difficulty in connecting the mainboard to a hdmi display? > arm-netbook mailing list arm-netbook@lists.phcomp.co.uk > http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook > Send large attachments to arm-netb...@files.phcomp.co.uk _______________________________________________ arm-netbook mailing list arm-netbook@lists.phcomp.co.uk http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to arm-netb...@files.phcomp.co.uk
