This thread is a review of Halong Mining's DragonMint T1, their first offering in the SHA256 market. There will be detailed pictures of the GUI and a hardware teardown.
The DragonMint T1 "Terminator" is Halong's first SHA-256 offering, utilizing AsicBoost with specifications advertised at 16TH, 1480W @ 240/25c, with an ±8% variation.
Halong Mining was first publicly advertised around November of 2017, with many prominent figures in the Bitcoin community endorsing the legitimacy of the project. Preorders were offered at $1350 for the miner. Myrig is advertised as Halong's distribution arm globally. The official websites, along with the twitter handles are listed below:

https://twitter.com/MyRig_comHalong Mining's representative, Scott O, was prominent on the Halong thread and that's when he advertised that he lived near Milwaukee. Being a resident here locally, I took Scott up on his open offer to review the unit in person, which I did in early January. I was delighted with what I saw, and became a customer not too long afterwards. Last month I offered to review a unit, which was provided in addition to the PSU, which I received yesterday.
Without further ado, the unboxing! As we can see, the unit has the standard "tube" form factor, a common form factor. The PSU has 10 PCI connectors, which plug into the 3 ASIC chains (3 each), and one in the control board.
More close ups, and plugging in the PSU! After plugging it into my setup, it didn't take long for it to show up on my network. I navigated to the page. The default login username is "admin", and the password is "dragonadmin"
The default pool settings! As with most miners, the hashrate spikes up when it first goes online, it equalized as time went on.
I adjusted the pool settings and pointed them to slush. Here's the GUI hashrate at two minutes, 10 minutes, 30 minutes, and finally at 75 minutes!
Poolside stats! Averaged at 16.07 TH in a bit over an hour.
Amp pull was fluctuating between 6.5 and 6.6 amps, which reflected consumption between 1560 and 1584 watts. The ambient heat in the room was hotter than usual, close to 30c/86f intake (thanks B29 miners!). I used a Fluke 323 Meter to measure the precise pull.
Here's the rest of the GUI!
GUI updates (existing and upcoming!) - including a demonstration of the color scheme change!
Onwards to the tear down! Off with the warranty seals. Halong has an official setup video here:

There currently are no firmware updates published on the website, however, Halong's Telegram (

published one for the T1 here (updated to Beta version - 041518) -

A special thanks goes out to Scott, Drak, Yoshi, and the rest of the team at Halong for providing me the unit to review. I look forward to seeing T2, T3, T4 and beyond! Maybe an "Enforcer?"
Stay tuned to the official twitter channels, telegram, and the website for more information for future releases from Halong!
