Early trial fitting of the next baseboard, which I designed yesterday evening and built today. This Easter has been a write-off as my partner is still in bed getting over the COVID infection I first caught over three weeks ago.

This is the first of three that will bridge the gap between the helix and the board in the back left corner of the room.

This board is in approximately the right position and the hatched area is to be cut out to ensure the board doesn’t interfere with the helix.

That’s it until the end of the week. I need to decide how this board is anchored to the helix board, and there is more than one way to do that. Needs some consideration.

Build your own tablet with this $31 Orange Pi CM5 baseboard

The Orange Pi CM5 is a computer-on-a-module that launched earlier this year with a Rockchip RK3588S processor and support for up to 16GB of memory. At the time Orange Pi introduced a baseboard for the CM5 that would give the little computer a bunch of ports including USB, HDMI, and Ethernet.

Now Orange Pi has launched a new baseboard designed to let you build your own tablet, although you could also use it for other applications. The new Orange Pi CM5 Tablet Base Board is available from Amazon for $31.

One of the biggest differences between the original baseboard and the tablet version is that the original had three Ethernet ports and the tablet board has none. But the tablet board supports WiFi 5 and Bluetooth 5.0, while the original board does not.

There’s also a 26-pin GPIO header, more interfaces for video output, allowing you to use a MIPI-DSI interface for a tablet screen and an M.2 2280 M-Key connector with support for a PCIe 2.0 NVMe x1 SSD.

Some of the Orange Pi CM5 Tablet Base Board’s key features include:

• 3 x 100-pin connectors for an Orange Pi CM5
• 1 x USB 3.0 Type-C (DP 1.4 alt mode and data)
• 1 x USB 3.0 Type-A
• 1 x USB 2.0 Type-A
• 1 x USB Type-C (for 5V/5A power)
• 1 x HDMI 2.1
• 1 x 3.5mm audio
• 1 x M.2 2280 PCIe 2.0 x1 connector
• 1 x microSD card reader
• 1 x MIPI-DSI 4-lane
• 2 x MIPI D-PHY RX 2-lane
• 1 x MIPI-CSI 4-lane
• 1 6-pin battery holder
• 1 x 26-pin connector
• 1 x onboard microphone
• 2 x speaker sockets
• 1 x IR receiver
• 1 x WiFi 5/BT 5.0 chip

The board measures 90 x 66mm (3.54″ x 2.6″) and weighs 43 grams (1.52 ounces).

While the board is relatively affordable, keep in mind that it’s useless without an Orange Pi CM5 compute module, which sells for around $78 and up at AliExpress or $87 and up at Amazon. And you’ll also need to supply you own display, battery, case, and other components if you’re actually looking to build a tablet.

I’m having trouble with the #mittersaw when cutting the ending of a long piece of #baseboard, the cut is always wrong cause it
is never completely flat against the machine.

I’ve tried double side tape+clamps+try to have the piece at the same level as the mitter saw but it always sag and the weight lift a little at the place where I’m cutting, ending with a bad cut that doesn’t fit well and wasted material that is discontinued and cannot buy more.

Any #tip is welcome 🙏
