It’s that time again… time to take something apart . This time it’s the D-Link DE-824TP 10BASE-T Ethernet Hub which I bought second hand back in 2003. Yes this one’s a hub, not a switch!

Just going to be a quick one.

We can see the power supply at the top left. The main board has 24x Ethernet filter modules for each port and 3 microcontrollers each handling 8 ports. There’s a BNC and AUX connectors at the back.

Just a close up of the power supply, to me it looks nicely laid out. What’s a bit odd is how the diodes are directly touching the board, they are a few centimetres above it.

Hehe, I just had to take this picture. I should have something made a bit more recently for my next teardown.

The Standalone Temperature Logger has now been updated to v2.0 with the PCB, schematic, guide and source all available for download.

I kind of took a little break and came back to figure out the PCB, once it was done all that was left was to try it out and create the new documentation for it. Since I’m using 2 SMD Mosfets I thought that soldering them would be really difficult but it turned out to be easier than I expected. Testing went well and am quite happy with how it turned out.

So go ahead and check out the updated project page for the Standalone Temperature Logger v2.0.
