It seems like everything in this hectic world is going digital. This Wireless Router with Analogue Utilization Meter project takes digital information and presents it in an analog form. This has some serious limitations. I do not know whether the hardware (broadcom chipset) or firmware (dd-wrt) contains the sampling algorythm that drives the LED, probably the chipset. Here’s the first issue, an LED must be on for around 30mS for the human eye to register it properly. Networking packets are much much shorter than this. So the router must do a little math and translate real network traffic in to slower LED blinking. So there is a sampling loss, the LED is a rough approximation of the actual traffic. Then, I must boost the 3.3V which drives the LED up to 14V required for the rev counter (most automotive dials and meters like this are linear 0-12 or 14V) For this I used a basic op-amp circuit. Without some swanky Digital to Analogue conversion I again loose a lot of resolution. In the end, this is not a very good representation of the traffic bandwidth being used, but the further I got in to the project, the more it became an interesting object of art and less a solution to the original problem.”

OMG. I need to make one of these!

Very nice to see a fusion of analog and digital in a item that looks as if it was made by a big company for mass production.

Looks like the guys wood working skills are only matched by his electronic skills, good job

Ya, I wish I had those wood working skills. If I attempted to build this there would most definitely be hot glue and duct tape involved.
