Flagging violence-adjacent content: "6000Vの高電圧でスイカを割ってみた" (smashing watermelons with high voltage) and "超高火力BBQでビニールシートを溶かしてしまった！" involve explosive or dangerous demonstrations, and a thermite video warns viewers against imitation.

About PJラボ＠高エネルギー技術研究室
PJラボ (@pj-lab) is a Japanese creator who posts high-energy DIY experiments on YouTube, including Tesla coils, high-voltage pulse power demonstrations, pulsejet engines and homemade machinery. The channel has been active since 2016, with 36 videos and a mix of Shorts and longer build logs. Upload pace has slowed sharply, with none in the last 365 days, which suggests the channel is dormant.
Estimates suggest the audience is mostly Japanese-speaking, skewing male and aged 25 to 44, with an engineering or hobbyist interest. Viewers appear to come from Japan with a smaller English-speaking share. Per the creator's website (htlab.net), the channel is run by a hobbyist who operates the HTLAB.NET project site, and the site describes its work as high-energy experimentation.
Sponsored integrations are rated at $150 to $250 per video. That works out to a CPM of $20 to $35 per 1,000 median views, compared with $10 to $30 for paid ads. Brands selling electronics tools or Japan-market engineering products should consider this creator.
