# :warning: :construction: **This page is WIP, but actively updated while I wait for things to ship!** :construction: :warning:

|
# Goal
|
|
|
|
To build a Full body set of trackers:
|
|
|
|
* 7 trackers
|
|
* 3 extensions
|
|
|
|
|
|
# Parts List & Prices
|
|
|
|
**NOTE:** *Some extra components were purchased in case of defects*
|
|
|
|
:warning: Huge caveats about the purchase list below :warning:
|
|
|
|
1. Buy more parts than I did, ( especially BMI's ) because
|
|
some of these have a horrible failure rate. 15+
|
|
|
|
2. Maybe throw in an extra D1 ( 11 total ) because these can fail too.
|
|
|
|
3. Batter chargers tend to be fine but can be prone to getting burned so be careful when soldering.
|
|
|
|
## Main parts from AliExpress:
|
|
|
|
* `10` D1 Mini for `20.53$`
|
|
* `13` BMI 160 for `18.99$`
|
|
* `10` 18650 Battery **chargers** for `6.81$`
|
|
* Keep in mind that this will also work for regular LIPO batteries
|
|
* *See battery section for explanation*
|
|
|
|
## Small parts from AliExpress:
|
|
|
|
* 10 pack of DPDT 2P2T Panel Mount Switches for `2.99$`
|
|
* 100 pack of 30K ohms for `4.05$`
|
|
* 5 pack of 4Pin JST connections for `4.93$`
|
|
* 50 pack of diodes for `2.53$`
|
|
|
|
## Batteries
|
|
|
|
For reference I bought:
|
|
|
|
* `1` ( 10 piece ) EHAO 804040 3.7V 18mAh for `32.77$`
|
|
|
|
While these do work, shipping time is pretty awful compared to everything else.
|
|
Looking at the order of a few months for some vendors.
|
|
To deal with this problem we can swap those out for some `18650`'s:
|
|
|
|
* 10 pack of battery clips `7.99$`
|
|
* Set of 10 batteries for `33.32$`
|
|
|
|
* Total with taxes: `41.14$`
|
|
|
|
I can attest that `18650batteries.com` is a reputable place to get batteries.
|
|
*SideNote: includes shipping but you're mileage may vary depending on source*
|
|
|
|
## Total Initial Cost With Shipping and Taxes
|
|
|
|
If you buy the 804040 batteries: `93.60$`
|
|
|
|
With the 18650's: `101.97$`
|
|
|
|
## Assembly
|
|
|
|
### Assumptions
|
|
|
|
That the parts list above is being used however the points below
|
|
are kept somewhat general.
|
|
|
|
### Equipment
|
|
|
|
Important to note that if you don't have soldering equipment you'll need
|
|
to get some.
|
|
Cheap kits can be found for under 50$ but make sure you have plenty of solder.
|
|
|
|
1. 18650's are heavy so if possible
|
|
|
|
For this reason it's not a bad idea to get some battery clips and mount
|
|
everything to that to keep things compact. When the weight of a tracker
|
|
is imbalanced then it's much harder to mount as it tends to "swing" more.
|
|
|
|
2. Heat shrink of varying sizes to clean up splices is basically required.
|
|
|
|
3. \*Flux if you want however this is really not required at all.
