Show HN: I fixed a dead Bitcoin ASIC and made a foundry that engraves your words

Strike a Block launched on Hacker News on August 20, 2026, as a service that engraves user-submitted text into Bitcoin blocks mined using a repaired ASIC, per the Show HN post by user laksgandikota.

The project originated with a salvaged piece of mining hardware. The founder described fixing a dead Bitcoin ASIC miner and then repurposing it not just for standard mining, but as a "foundry" that embeds custom messages into the Bitcoin blockchain on behalf of paying customers, according to the HN submission. The site, strikeablock.com, serves as the storefront for the service.

The core offering lets users submit words or phrases that get inscribed into a Bitcoin block when one is successfully mined by the repaired ASIC. The concept sits at the intersection of hobbyist Bitcoin mining and on-chain inscription, similar in spirit to services that embed text in OP_RETURN outputs or, more recently, Ordinals-style inscriptions — though the specific technical mechanism used by Strike a Block is not detailed in the available source material.

The HN post received 1 point and no comments at the time of publication, suggesting early-stage visibility. No pricing, revenue figures, founding date, incorporation details, or additional team members are mentioned in the source.

No corroborating sources were available for this story. All details derive solely from the Show HN submission; claims about the hardware repair, the mining operation, and the engraving service have not been independently verified. What happens next depends on whether the solo miner successfully mines a block — an outcome that, at current network difficulty, is statistically unlikely for a single consumer-grade ASIC.
