A recent Hackaday article highlights a DIY Stream Deck radio controller built with Cheap Yellow Display by an individual known as [WhiskeyTangoHotel], utilizing an inexpensive “Cheap Yellow Display” (CYD). This innovative project, detailed on [WhiskeyTangoHotel]’s website on March 17, 2026, focuses on creating a cost-effective alternative to commercial stream decks for controlling a Flex Radio 6400 ham radio transceiver, offering significant value to the amateur radio community.
The Ingenuity Behind the DIY Controller
The project involves building a custom controller that functions similarly to a commercial Stream Deck, but at a significantly lower cost. Stream Decks are programmable keypads with customizable LCD buttons, often used by gamers and streamers to trigger actions, control software, and manage various functions on their computers. [WhiskeyTangoHotel]’s version is specifically designed for ham radio operation, aiming to simplify the control of a Flex Radio 6400, a sophisticated piece of equipment.
Stream Deck Radio Controller Built With Cheap Yellow Display: Components and Affordability
The core of the project is the “Cheap Yellow Display” (CYD), an ESP32 development board. This board is notable for its affordability, typically costing around $9 to $18 USD on platforms like AliExpress. The CYD (also known as ESP32-2432S028R) includes an ESP32 microcontroller with Wi-Fi and Bluetooth, a 320×480 resistive touchscreen, USB connectivity, and an SD card socket. This makes it a versatile and attractive option for DIY projects, showcasing how powerful tools can be assembled from budget-friendly components. This approach significantly reduces the barrier to entry for advanced radio control.
“The ‘Cheap Yellow Display’ offers an unprecedented combination of affordability and functionality, making advanced custom control accessible to a wider audience of hobbyists.”
The creator, [WhiskeyTangoHotel], developed this “Poorman’s Stream Deck” to provide a more economical solution for controlling advanced ham radio transceivers like the Flex Radio 6400. Commercial Stream Decks, while useful, can be considered pricey for what are essentially programmable button boxes. The motivation behind this build is to offer similar functionality and convenience without the high cost, leveraging readily available and inexpensive components. This innovation provides a practical Stream Deck radio controller built with Cheap Yellow Display for enthusiasts.
