| A "high-end" 858D desoldering station |

The "cheap crap" 858D+ design seems really good to me. Yes, they're almost all (all?) made of Chinesium and a fire hazard. HOWEVER... What would happen if someone built an 858D clone with real, brand-name, parts? With real firmware, all the safety sensing and such. I think it's a really good clever design that only lacks some polish. Something in the $100US range. I own the Weller. I own the Quick. I own several 858 clones. I compare them all. The 858 in terms of price versus performance is king! This design is elegant and price effective. They just need to use better quality parts and firmware. Then it would beat the best. Yes, the Weller and Quick are faster in absolute terms but they're using actual 700+W/1000W elements whereas the Chinese parts are using 500W/600W parts probably due to safety design concerns. All things being equal I think the 858 design would destroy everything else. Am I missing something? |

I have the Quick 957DW and a Yihua 858D. I am going to find someone local to give the Yihua to as it is just sitting on the shelf gathering dust. The Quick is so much nicer, even with the somewhat stiff hose. I doubt the Chinese units are using 500W/600W instead of larger elements for safety concerns. I have seen the inside of both my units. No comparison. An 858D with a 700+W heater would probably be a real fire starter. At lease, my Yihua was wired correctly and didn't need fixed. |

Rolling your own PCB using the open firmware is just a matter of putting in the time and effort. The problem with replacing the handle is it will drive up the cost to several hundred dollars. Should be able to keep it around $30 with a repurposed transformer, PCB, microcontroller, misc components etc. https://www.eevblog.com/forum/reviews/youyue-858d-some-reverse-engineering-custom-firmware/ |
