SLIM19 PART I _ REV_1

Getting Started: Preface, Sources, Shopping List.

PREFACE

  I did not make the Loki kit, figure out the modifications on the APW3++, or design the SLIM19. If anything, this guide should be seen as a resource to find what others have already put out, and easily navigate through your first build. All resources are credited, and if I slip up and share something without attribution, please let me know.      

I asked SatStackingPleb if I could put together a guide for the SLIM19, and he agreed. This has been my favorite LOKI build so far (after trying many). This is a perfect build for an intermediate builder or a beginner with some guidance. It recycles last generation’s miners into useful lottery miners or even a steady source of SATS via pool mining. The cost/TH is much lower than some of the other projects that exist, and the ability to use residential power has kept us little guys in the fight while industrial scale mining manufacturers cater to that customer. 

 The only downside is that it still relies on blackbox hardware. Meaning, it isn’t an exact science and resources are scarce for troubleshooting, customer service is non-existent, and the guy that made the equipment is probably openly hostile to your existence. Make sure you have a thorough understanding of what you are getting into before attempting this build. There are a lot of resources for Pleb-mining builders and I will list some to get you started at the end of this guide.

*DISCLAIMER******: ANYTHING YOU DO IS ON YOU. SOMETIMES WHEN YOU FA, IT DOES, IN FACT, LEAD TO FO. 

It is possible to hurt yourself or your hardware attempting this build. I have sent one KPRO hashboard to the great beyond by being too complacent and destroyed a couple control boards learning how to solder, not to mention the rolls and rolls of filament I have wasted figuring out how to 3D print the furniture for the chassis. This is the tuition for your advanced degree in Pleb Studies. 

   This guide is meant to be a jumping off point so that we can share data and I can update this guide as needed. I have only built SLIM19-KPROs, so I know what works for a KPRO hashboard. I will supply a form so your data will be included, and if you have a better way of doing something, or an optimization, I will happily revise this guide to encompass your Proof of Work and credit you accordingly.

  15. (2) GELIED GALE FORCE FANS, OR NOCTUA FANS. (ENSURE YOU PRINT THE RIGHT Fan housing to correspond to the fans you get) *See Print section for details

  16. PAINT (HEAT RESISTANT) *OPTIONAL

  17. PETG CARBON FIBER FILAMENT

  18. 125V POWER CORD ( 14AWG) 

TOOLS

  1. Crimping tool: Make sure it is rated for 4AWG

  2. Wire Shear Cutter: 4AWG

  3. Cable Stripper 

  4. Hot Air Rework Station *Optional (you can also use a lighter).

  5. Soldering station hand (Holder) *Optional, but it makes life a bit easier when you aren’t looking for a way to steady the control board while you are desoldering/ soldering. 

  6. Breadboard Jumpers: Dupont Wires 24AWG, 2.54 Male to Female. (I use this instead of the dual jumper that is standard in the Loki Kit). No reason really, but it works fine. Can also use the Female to Female Jumper provided in the LOKI kit.
