Note

I have a new carrier PCB which is smaller and more optimized than the Hyperion PCB. The entire assembly with case for the 503759 battery is smaller and lighter than the Hyperion one in this repository. The PCB and Case files for meowCarrier PCB can be found here: https://github.com/Shine-Bright-Meow/meowCarrier/blob/main/README.md

Important

Purchase 30% more boards (WeMos D1 Mini, TP4056, and LSM6DSR/LSM6DSV/ICM-45686 than what is needed. There is the possibility that components are dead on arrival or get damaged during assembly/soldering.

Note

One order of Resistors, Diodes, Header Pins, Switches, and PH 2.0mm Connectors is enough for the entire project.

Note

The SlimeVR DIY Community recommends buying boards from the following sellers on AliExpress: Win Win, Aitexm, or Tenstar Robot.

Note

Type-C Ports are more durable. As for charging, USB-C to USB-C Power Delivery doesn't work. Use USB-A to USB-C cables to charge trackers.

Important

When purchasing components, some have multiple variants on the same product page like Diodes and Resistor. Be sure to select the correct one.

Tip

In your AliExpress Cart, you can verify that you selected the correct variant of the component here.

Optional Components (PCB)

Note

I recommend using Sheathed Wire Cable and soldering it directly onto the PCB for extensions. (JST XH Connector is not needed for this method) Usually, less connection issues than using connectors.

Recommended Consumables/Tools

Component	Variant	Link
Soldering Iron	Any with BC2 Tip	https://www.aliexpress.us/item/3256805553022893.html
Solder Sucker	SS-02 or SS-02 Clone	https://www.aliexpress.us/item/3256805437410900.html
Desoldewring Iron	Choose your electrical outlet	https://www.aliexpress.us/item/3256804929123151.html
Rosin Flux	Liquid or Gel Type	N/A

Note

You will have a much better soldering experience with better tools. These are my recommended (but still on a budget) Soldering Iron and Solder Sucker if you don't have these tools or better already. They will work much better than those Amazon $10-20 soldering kits/iron.

Note

The Soldering Iron listed requires an USB Type-C Power Delivery charging block of 60W or higher.

Recommended Components (Case)

Component	Variant	Link
Trilancer Elastic Cinch Straps	See note below	https://www.amazon.com/dp/B099RNRT7Z
GoPro Chest Mount Harness	See note below	https://www.aliexpress.us/item/3256805774922789.html

Note

12in works for ankles. 18in for thinner thighs and 24in for thicker thighs. Chest (if not using GoPro Chest Harness) and Hips can be done by doubling up on 18in/24in straps. Choose what you need for your body and how many trackers you are planning to make. 3 Size Combo and either 18in/24in package would be a start.

Note

There are 2 types of GoPro Chest Mount Harness. One that clips in and the other one fasten by a bolt. Be sure to purchase one one for the case you are 3D Printing.

Ordering PCBs from JLCPCB

1. Download the Gerber file from here.
2. Go to JLCPCB.
3. Click on "Add Gerber File" and upload the zip Gerber file.

4. Select the PCB Qty and PCB Color of your choice. Select 1.0 for PCB Thickness and select "Specify a location" for Remove Order Number.

Important

Set PCB Thickness to 1.0 if you are using the case from this repository.

Note

When ordering PCBs, please check if the case recommends a certain thickness it is designed for. For example, the case in this repository and Cheesecake recommend 1.0mm Thickness. If unspecified, the default 1.6mm will do. The case in this repository has loose tolerances incase you ordered the default 1.6mm thickness, it will work okay.

Note

JLCPCB usually produces Green colored PCB the quickness. Other colors have additional days added.

Note

For Remove Order Number, when "Specify a location" is selected, it will the order number will be printed at where the text JLCJLCJLCJLC is located. In this case, at the bottom of the TP4056 module footprint.

Soldering/Assembly Guide

Written Guide

Warning

Please work at a well ventilated area. It is recommended to use a fume extractor if working indoors. If you do not have one, use a fan to blow fumes/smoke away from your face.

Warning

It is recommended to use eye production. Especially when splitting header pins apart with a cutter and when trimming down header pins and ends of resistors/diodes.

Warning

If working with leaded solder, be sure to wash your hands when you are done including under your fingernails. Wipe down and vacuum the floors and surfaces of your workspace and anything you may have cross-contaminated.

Tip

Using external flux (preferably Rosin) will allow solder to flow to automatically flow into the correct area.

Tip

A wooden clothespin can be used to hold the boards together while soldering.

Note

Resistor and Diodes

Battery Connector

With JST PH 2.0mm 2P Connector

1. Place connector as positioned on the photo. The opening should be facing teh cutout and the smooth side should be on top and the slotted side should e against the PCB.
2. Solder the 2 pins in the back.
3. Trim excess length of pins using a flush cutter. Use your wire cutter if you don't have a flush cutter and cut as close the the PCB as you can.

Note

If you got straight pin connectors, you can bend them 90 degrees, so they will work. There will be a little less pin length sticking out from the back to solder and there is a chance of you snapping them. You should have plenty of connectors incase the pin snaps.

Without JST Connector

Important

This step should be done last after the entire board is assembled and after you verified that the solder joints all look fine.

Important

Do not solder the battery leads to the holes of the PCB. The angle will put stress on the wire and solder joint and will eventually break off.

1. Strip the battery leads they are not exposed already.

Warning

Do not let the exposed battery leads make contact with each other.

2. Place your soldering iron on the BAT+ pad and melt the solder.
3. Place the RED battery lead in the molten solder pad and let it cool off.
4. Repeat the process for the BAT- pad and the BLACK battery lead.

Diodes

Note

Make sure the diode is facing the correct direction and has the correct values. It will not be easy to access the diode once you solder the IMU above it.

1. Verify that the diodes are 1N5817. You can find the text on the body.

2. Place the diode's striped (grey/silver) on the narrow stripe indicated on the silkscreen.

3. Bend the ends in 90 degrees, so it is shaped like a staple and place into the through-hole.
4. Pull the excess on the back until diode is flush with the PCB.
5. Solder ends from the back.
6. Repeat for other diode.
7. Trim excess length of pins using a flush cutter. Use your wire cutter if you don't have a flush cutter and cut as close the the PCB as you can.

Resistor

Note

Make sure the resistor is the correct value. It will not be easy to access the resistor once you solder the IMU above it.

1. Verify the resistor is 180K. The first 4 colors should go in this order:

• Brown
• Grey
• Black
• Orange

2. Bend the ends in 90 degrees, so it is shaped like a staple and place into the through-hole. Resistors are not polarized, so the direction does not matter.
3. Pull the excess on the back until resistor is flush with the PCB.
4. Trim excess length of pins using a flush cutter. Use your wire cutter if you don't have a flush cutter and cut as close the the PCB as you can.

Case Guide

The case consists of 3 files: Case, Lid, and Tray.

Printer Settings used:

• Printer: Creality CR-10 S5
• Infill: 100%
• No Rafts or Supports
• Resolution: 0.2mm
• Nozzle: 0.4mm
• Tested with PLA+ and PETG

Tip

For stronger strap loops, print the base/bottom 4mm layers with 0% (solid) infill for just the case file. Printing with a zig-zap pattern instead of line will help prevent strap loops from breaking at the weak point where layers join horizontally or vertically. These are done in your Slicer.

Case

Case Photo by Higanbana (Meia)

• No AUX hasa solid back portion.
• AUX JST Cutout has a JST XH 2.54mm 4P-Pin or 5-Pin connector in the back for extension trackers. The non-noted version is for the Multi-IMU version of the PCB and the noted version is for Lupinixx's BMI160 Version.
• 50mm Strap Loops are the normal for fastening the tracker to your body. You can always use smaller straps.
• GoPro Chest Harness Adapter snaps into the harness clip from the top. It is more stable for chest tracking and won't slip down your body.

Important

GoPro Chest Harness Tracker will have a different IMU rotation than your other trackers.

Tray

• SS22F32 is a flat tray since the switch is supported by wedging against the PCB and Case.
• SS12D00G3 tray has a craddle for the switch to go into. It prevents the pins from being bent when turning on or off the tracker.

Troubleshooting

Join SlimeVR Discord and ask in either the #technical-support or #DIY channels. It would be helpful for you to provide a description of your issue, photos of your soldering (front & back), and a log output from Settings > Serial Console with your tracker plugged into your computer via data USB cable into your WeMos D1 Port (non-charging). You will need to press the Reboot button to get the complete log.

Using a Multimeter

1. Go to the drawing located here.
2. Scroll down to the PCB section and click the Open in Editor button.

3. Mouseover each pad and see which pads they are also connected to.

4. Set your multimeter to continuity mode.

5. Test for continuity between the pad you have highlighted with your mouse and every pad that is connected to it. Do this for every trace.

Note

Also, test the switch for continuity in the on position.
