I came here expecting a literal machine that dispenses voodoo dolls.
You have a start, but you'll need to expand on this a bit. How are you going to take this item, and use it to support a full article? The problem here is this seems like a well-worn trope (a disaster predictor) that I'm sure has been done (I perused the 'predictive' tag to no avail, but I only looked through a dozen or so without finding one). Even if we don't have one, it is a vanilla trope to begin with imo, and would still need more than to simply exist to survive on the mainlist.
How do you think you're going to work it? The first thing that comes to mind due to its operation is of course experiments/testing log. There's an issue here though, in that there are only so many ways to cause death and misery, and something like this could rapidly get stale. SCP-2236 and the more recent SCP-2486 take this route (testing logs), though each is sustained by a more original/unique base concept and take it in some very interesting directions.
Let's take another example though, with a similar device: SCP-2203. Although this is still test-log heavy; the focus is not on the anomalous effects of the device, but rather on the people affected by it. Perhaps you can focus on the impact this device has on them on a deeper level than merely listing a Series of Unfortunate Events. Can anything unexpected and good come out of using this device? What could you tell us about your subjects using these photographs? Will anyone experience change, rather than simply having something happen to them?
