I’ve been seeing these kits pop up a lot recently and wanted to play around with one myself – only problem is, they’re either too expensive, already have something mounted on it (usually a moon or skull), or take over a month to ship. Can anyone point me to some resources to build my own? Most I’ve found are using permanent magnets, not electromagnets, and are for very specific objects like tops or spoons. I’ve also found some guides on how to build some that you can hang stuff like spoons and nails from but I want it to be right-side-up.
