Just looking into some full wave rectification without diodes and I have so far found 2 ways. One with 2 op amps, quite costly, or one promising one with just a transistor:
I do like the look of this, might be right up my street. It does look slightly jubious, but its worth a [...]
I found this that is essentially what I thought of the other day, bastards, always knick my ideas (One must admit that they had the idea months ago :D). I personally think that mine would be better though, because it looks like they are using modulated IR face up to detect when someone goes [...]
Ive recently been playing with a new analytical solution to the multilateration problem, but its complicated and I dont fully understand the maths behind it yet because it was Kevin’s work, not mine. Ive been implementing it into the disdrometer simulation software but results are poor so far. The largest problem is that the principle [...]
Just been doing some bored research again, and I came accross this image:
This would be a good route to investigate when I do get it up and running. I Could initially scan for objects, then focus in using this technique. First seen here but there must be other sources out there. Hence, [...]
