Brain Box Mini Plus with FM RadioBrainbox manufactures a fantastic range of electronic kits featuring an easy to use press stud system for making contacts. These kits are reminiscent of the ones from my childhood, but they're much easier to handle, without any pesky wire to misplace or injure yourself with. Brain Box Mini Plus with FM Radio, like all Brainbox kits, requires no soldering or trimming. The kit uses simple, brightly coloured components with press stud connectors.
