This credit-card size flex circuit translates the resistance between two probes into the resistor colour code. Conveniently the resistor colour code chart can be mounted just bellow the LEDs so that you don’t actually have to remember it for this tool to be useful. This version is a first prototype and with through-hole components not the most slim design. A next iteration it would be nice to switch to SMD components and make it slim enough to actually fit into your wallet. Being able to measure resistance everywhere you go will change your interactions with the world:-)
