CrossWatch Gets a Housing

The Housing

The CrossWatch finally received a housing, well sort of, PlumPot finally decided to stick to a housing design for now.
A person can improve and improve a design to be better and better, especially if you two diffrent people that have two diffrent opinions, so when both Plum at Pot was sort of happy with the design we jumped at it and froze it for version 1. The housing was designed on free web site called TinkerCad. TinkerCad is a 3D rending tool designed by Autodesk. Its perfect for beginners to get introduced to the world of 3D printing

K.I.S.S

Sometimes as engineers we always try to complicate things and always try to make things as ‘fancy’ as possible. In times like those its always good to remember the phrase K.I.S.S (Keep It Simple Stupid). and that is exactly what PlumPot did in this housing. The housing consists of 3 buttons and one hole for the LED display. With these 3 buttons the user will be able to navigate select workouts and count the reps that is needed.

3D Rendering

It is a great time to be alive, in today world one can draw a housing and then import in your electronics hardware design and have a look if it will fit, and that is exactly what we did. From TinkerCad we exported a STL file and import it in to Altium Designer. Altium designer is a engineering design assistant tool that allows the user to create PCB’s for electronics design.  Altium is a premier package and not always available for the normal person. Another tool that is free and more than capable is EASYEDA (https://easyeda.com/). This is a free tool more than capable for someone starting out

Bringing it to Life.

Housing

Once a housing was agreed upon, it needed to be seen if it was possible to print and how easy will be to successfully print the housing. Printing was done on a Flashforge 3.  The images below are early prints with diffrent 3D printer materials namely ABS and PLA. PLA is a much easier material to print as ABS. I would not advise ABS for beginners

 

THE PCB(Electronics)

Like mentioned earlier the PCB was made using Altium designer. PCB where order by https://jlcpcb.com/. JLCPCB is a Chinese manufacturer that focuses on quick proto types and extremely cheap. The shopping is more expensive than the PCB itself.  Below are the images from computer simulation (left) and real-life PCB(Right) it’s crazy how life like it has become.

What is next?

PlumPot Finally has all the pieces to complete the first self-manufactured version of the CrossWatch, this week the PCB will be populated and see how good the housing actually is.  Once that is completed it will be full steam on programming the CrossWatch and the LCD display. If all goes well, we will have a working prototype end of May to show the Crossfit community.

19.5 – OPEN 2019

19.5 The big Nope!

The Workout

For total time:

33-27-21-15-9 reps for time of:
95-lb/43kg. thrusters
Chest-to-bar pull-ups

Time cap: 20 minutes

The Crosswatch being used

19.5 was one where you look at the clock and you start question your life choices and why are you doing this to yourself. The CrossWatch was a big help with keeping track of the amount of reps that are remaining. We all had those moments while judging, and the athlete asks that one big question, “How many reps are left” and you were more focused on is the athlete breaking 90 degrees and is the head pushed through for the thruster. The CrossWatch kept track of all the reps so the judge did not even have to second guess how many reps are left. Many relationships can be saved by this watch.

The Layout

Below is the layout of the CrossWatch for 19.5. We tried to make it as user friendly as possible. Navigation is done with the left and right buttons and the top button is the “OK” button.

19.4 – OPEN 2019

19.4 was the one where you close your eyes and GO!!

The Workout

For total time:
3 rounds of:
10 snatches
12 bar-facing burpees
Then, rest 3 minutes before continuing with:
3 rounds of:
10 bar muscle-ups
12 bar-facing burpees

Men snatch 95 lb/43kg.
Time cap: 12 minutes

The Crosswatch being used

19.4 was the best test we had for the CrossWatch. This workout had an interesting catch and that was that people will rest for 3 minutes at diffrent times.  So, if the athlete was done with the first part of the workout, the judge quickly had to look up and take note of the time and then take note of when the athlete had to go again. Well the CrossWatch did all this for you and you could just focus on the judging. The CrossWatch saved the split time and the started counting down the 3 minutes that the athlete had to rest. If an athlete took longer than 9 minutes to finish the first part, then the Watch would not wait till the 12 minutes us up just to give the athlete the score.

19.3 – OPEN 2019

19.3 The one that required a neck brace

The Workout

The Crossfit open workout 19.3 required a neck of steel

For time:
200-ft. dumbbell overhead lunge
50 dumbbell box step-ups
50 strict handstand push-ups
200-ft. handstand walk

50-lb. dumbbell, 24-in. box
Time cap: 10 minutes

This was all about your engine and how long one can embrace the pain cave.

The Crosswatch being used

19.3 was a simple yet effective workout that killed the shoulders and made you dream of doing your first strict hand stand push up. The CrossWatch was at it again, counting the reps with ease, leaving the judge to focus on good form and not once have to look at the piece of paper, to keep track of how many reps have been and how many has been left. The CrossWatch kept track of all the split times needed. It became very clear how important accurate timing is, when Rich beat Patrick Velner by 1sec in 19.2!!

The Crossfit open workout 19.2 was:

Beginning on an 8-minute clock, complete as many reps as possible of:

  25 toes-to-bars

  50 double-unders

  15 squat cleans, 135 lb.

  25 toes-to-bars

  50 double-unders

  25 toes-to-bars

  50 double-unders

  11 squat cleans, 225 lb.

If completed before 12 minutes, add 4 minutes to the clock and proceed to:

  25 toes-to-bars

  9 squat cleans, 275 lb.

If completed before 16 minutes, add 4 minutes to the clock and proceed to:

  25 toes-to-bars

  50 double-unders

  7 squat cleans, 315 lb.

Stop at 20 minutes.

The Crosswatch being used

19.2 gave the CrossWatch a proper test. This was an interesting workout as there where diffrent parts to it. Depending on your level of fitness, will depend how long this workout was for you. The watch had to be able to keep track if the amount of reps where completed in the allotted time, if not the watch had to stop and give you your reps and your split times after the double unders. If the athlete managed to finish the reps required in the required time, it will just keep going on, until the 20min are done.

19.1 – OPEN 2019

19.1 was the tall-mans' dream

The Workout

The Crossfit open workout 19.1 was any tall crossfit athletes’ dream:

Complete as many rounds as possible in 15 minutes of:
19 wall-ball shots
19-cal. row

This was all about your engine and how long one can embrace the pain cave.

The Crosswatch being used

This was the first crossfit workout where the watch was tested. Since this was a pretty simple workut to keep score, PlumPot decided to add a special feature to the watch. The watch had the ability to keep track of the projected reps that the athlete would get after the 15min time cap. Most athletes go into a workout with a goal. When your judge has this goal in mind he can motivate you to go faster or reassure you that you are on the right pace.
