Jamcorder founder announced sales of 2,500 units of an automated MIDI recording device. He said hardware proved simpler than expected. The founder, previously a software engineer, had anticipated complex design, component shortages, and manufacturing hurdles. After assembling 500 units himself in four days with no modifications, he found the hardware process straightforward. The most time‑intensive work was software, involving about 200,000 lines of code across firmware and applications, which took more than three years to develop. The device uses a printed circuit board with 25 components, custom MIDI connectors, and off‑the‑shelf parts; assembly requires only a single screw. He recommended keeping the bill of materials simple, avoiding single‑manufacturer components, partnering with assembly houses, targeting at least a 70 % gross margin, maintaining a lean organization, implementing anti‑counterfeit measures, performing in‑house quality checks, requesting production samples, documenting manufacturing steps, and using compact packaging. He noted that scaling the product beyond the current volume would introduce new challenges, but for his current level hardware remained manageable.
