Can I use the Targets with BB’s?
Yes, the targets can be used with Nerf darts, discs and BB’s. However with BB’s it is recommended to place a cutout of a layer of foam i.e. “Fab Foam” in the Paper Holder is protect the Target and to reduce the amount the BB’s bounce back off the Target (invariably directly back at the firer!).
Can I attach the Electronics to other Things?
Yes, you don’t have to use the Perspex target bases. The circuit is basically a shock sensor and so can be attached to any surface, which will then turn it into your target.
Can you please provide the schematic for the design?
If you look on the Technical Details tab of https://spellfoundry.com/product/target-electronics-kit/ it’s there.
