melts Pimp Tower build 2017
Hey PiMPs this is melt with a fun project write up. I am just an ordinary person building rigs for ordinary people.
Create a rig that meets the following guidelines:
Use common, cheap materials and simple tools: We want to use cheap, free or common materials that can be found in most countries. (Besides the electrical, which you cannot skimp on. Also, I am an electrician, most pimps will want to hire an electrician to do this work according to Codes.)
Homemade and easy to build: Wanted to have some fun with this one and I was making it up as I went along, so I used parts that I had laying around.
Saves floorspace: In order to conserve floor space in my tiny home I wanted this to be a tower of rigs like a stack, so we named it the Pimp Tower Build.
Allows cooling management: Planning to put sides and a clear plastic front on to allow the stack to function like a push/pull.
Portable: Can unplug and move the entire rack if needed, but there is a wheeled dolly and extra play in the electrical lines coming in, to allow the rack to be moved around.
- deck screws
- 1 wire rack
- romex and romex staples
- black spraypaint
- 4" j-boxes, j-box extension rings, handyboxes, box connectors, receptacles, plates
- 20" box fans
- DROK ammeters
- window fan of your choice
- green LED christmas lights
- articulating vesa100 monitor arm
- r-3 foam insulation board
- lots of love for elite looking pimp mining rigs
We took lots of photos for this one...
Step 01: Build the frame out of 2x4's. This was designed for 6-7GPUs wide and 4 rigs tall. We wanted a little more strength so we used deck screws instead of the air nailer.
2x4 Dimensional lumber, Outside Dims: 24" W x 60" H x 18" D
Fasteners: 2" and 4" Deck Screws
Step 02: Take a 18" deep wire rack and cut off 4 sections.
Step 03: Measure for each rack and hammer a Romex staple at each corner for each rack to sit on.
Step 04: Slide the racks in and Ziptie them to the Romex Staples.
Step 05: Black Spraypaint the entire thing.
Step 06: Install 4" square Junction box for each rig.
Step 07: Use romex and romex box connectors to run the power feeds back to the main panel.
Step 08: Install receptacles and J-box cover plates.
Step 09: Pull the meter if possible. Then install new circuit breakers and tie the new branch circuits in.
Step 10: Cut some 1/2" PVC in 12" lengths and spraypaint black. Zip tie these to the wire racks for electrical and cooling standoffs for the motherboards.
Step 11: Install a network switch and run Cat5e cabling from the switch to the upstream router and to each rig's motherboard NIC port location, zip tie it into the rack nicely.
Note: We had an extra LED undercabinet light fixture laying around, which we installed in the top of this tower, but we never use it. We wired it into the first rig's J-box for convenience.
Step 12: Install all your rigs! Zip tie the GPUs to the wire rack, put the motherboards and PSU in, and plug up the power.
Start with the mobos:
Step 13: We use velcro rolls and velcro ties to secure all rig cabling that is not permanently installed.
We also installed a power strip on the back that was plugged into a wall receptacle, this is to plug in all our accessories: The window fan (pictured) and the box fans and lights (not yet installed). Still in the planning phase, not much cable management / cleanup was done yet.
Here are some cool close-ups:
We then found some crap R-3 rigid foam wall insulation and cut two 60"x18" strips. We ended up spraying the outsides black just for looks and then gluing a nice PIMP logo on the side for awesomeness.
Check the little "development section" over to the right!
You can see here we tried using the window fans in various configurations to see what happened with the temps. Also, the climate was changing a lot and we were trying to either circulate the heat to warm up the house for free, or exhaust out the window. Ultimately we added some box fans.
We also printed up some quick and easy rig labels wit the rigs name (IP octet) on some 5160 Address Labels that were laying around the pimp office. No loose paper is allowed around the rigs so these stick safely and perfectly on the frame.
AND THEN THERE WERE PiMP GREEN LIGHTS EVERYWHERE!
In this photo next to the nice lady there is the first "prototype" of the 240V receptacle with Amp/Watt/Voltmeter. We built this out of a DROK ammeter with CT, L6-30R Twist-Lok 240V 30A receptacle, and J-boxes and Handiboxes.
Mrs melt took a quick opportunity to capture some labor of love.
Close-up of the 240V infrastructure:
Here is how we did it: This was for 3 boxes, you can do however many you like.
First, cut and mount a backboard (plywood, MDF, OSB, etc) to the wall. We used tapcons to secure it to the block wall.
Mount 4" J-box, with J-box extension ring.
Install box connector and Handy box.
Superglue the DROK meter around the edge to the GFCI cover plate.
Install wiring, making sure to run one of the hot lines through the CT ring of the DROK meter, to the receptacle, and then back to the meter for voltage readings, according to the DROK instructions.
Install receptacle and plate.
Label with panel and breaker number.
Comb and bundle the romexes and staple them down to the board.
you can see in this next picture that we zip tied some 20" Lasko box fans blowing away from the GPUs to suck the heat toward the window. This is nice because when you are working with the rigs or showing them off you do not have to stand in the hair dryer, so to speak.
Then we string up MORE GREEN LIGHTS! PiMP PRiDE!!!
This looks so cool when you're in there. The photo really doesn't do it justice.
Also, bought an articulated monitor mount and mounted it to the wall so it would reach all of the rigs in the tower and in the wire rack development area. So I can plug up a monitor and keyboard to any rig if for some reason it does not boot up and become available via miner.farm and/or ssh.
We also reconfigured several times. At this time you can see that we now have the ability to run 240V and 120V power supplies as needed.
Thanks for checking out my little project. This is in between spending most of my time on the discord and the forum with all of the pimps and the miners in our partner communities. I hope that it inspires you to keep the spirit of the miner and always be celebrating this crypto thing that we are a part of and being free to exchange money with anyone we like.
Please post your own rigs in the Rig Showcase because this is something that is a personal passion of mine and I enjoy being around all of you very much. Take care miners and friends and I hope that PiMP family helps you make more hash and more cash using our mining tools!
We promise to keep your email safe and never spam you.
