I think for a quick personal project, you can try a Raspberry Pi and install Electrum on it. Then create a new wallet on Electrum on the Pi, get the master public key, and create a watch-only wallet on your regular computer. When you want to send an amount, create the transaction on the regular computer Electrum watch-only wallet, transfer the transaction to the Pi, sign it on the Pi, then transfer it back to the regular computer and broadcast from there. Basically, those operations, automated, are what a hardware wallet does.
