Tom Fleet writes on Hackster about the reTIL from Alex (@tinyledmatrix): reimagined, resin-cast, retro-tech style programmable TIL311 LED hexadecimal display replacement:
This Modern Day Take on the TIL311 Shines a Light on How to Deal with Part Obsolescence!
Packing the tiny array of individual single LED pixels into place, along with a super-smol STM8S QFN MCU, all on the front face of the PCB, leaves a layout that is almost indistinguishable from the TIL311 when illuminated.
But, @tinyledmatrix didn’t stop there, oh no. Striving for a true-to-form-factor facsimile, the re-vamped PICTIL is placed into a mold, before being cast in the same tinted resin — and the results are just stunning. Below, we can see the fruits of the labour, with the new, modern take shown on the left, and the original TIL311 to the right
Installed in a product, you’d be hard pushed to tell the difference once the LEDs are lit up!
