Yeah probably. I found another company, this is from India, should be cheaper (?)

https://www.radiantdesign.in/

 

I think they focus more on the design part than manufacturing, but can't hurt to contact them. I googled for these keywords: custom enclosure wearable

I'm sure you will eventually find a suitable company, good luck.

My wearable power supply is almost finished.  It is expensive indeed.

Where is your schematic?  You can find an alternate design and save money---why expensive, is it high power? 

When in the dark remember-the future looks brighter than ever.   I look forward to being able to predict the future!

common with "wearables" is that it needs to be very small and light - which can be challenging and, hence, more expensive.

For a design with frequent battery replacement, it can be cheap.

 

However, my goal is an auto-powering wearable without further battery replacement and maintenance.  In addition, the case is very small so the design becomes expensive.

 

Another crucial factor is the Bluetooth frequency which is 2.4GHz!  It requires much power to generate it!  Peak power may reach 100mW!!!

 

A very tricky design as a whole!  surprise

No, that's not a given at all - you need to be clear if you mean BT Classic or BLE (or dual-mode).

Also not true.

 

Although Audio might be the commonest use seen by consumers, BT Classic has many other profiles & uses.

 

https://learn.sparkfun.com/tutorials/bluetooth-basics/bluetooth-profiles

 

The BT Serial Port Profile (SPP) is probably the best known around here; eg, the common HC-05 modules.

 

SPP is notably absent from BLE.

Here are my new air quality monitor's spec:

  1. 30mm x 25mm x 7mm;
  2. wearable as a wrist band or badge;
  3. BLE tablet or phone app as monitor GUI;
  4. readings update every 5 seconds;
  5. Can measure CO2, volatile toxic organic gases, temp, humid, UV index, etc.
  6. Auto-powering; to boot this wearable, place it under sun light and it will last for at least 3 years;
  7. No battery replacement or maintenance within warrantee period;
  8. very beautiful appearance,etc.
  9. 3 years 1 to 1 replacement warrantee;
  10. Kids friendly;
  11. United Kingdom Q Mark (pending)

 

Please suggest a retail price or crowd-funding backer's price?  laugh enlightened

 

For your reference, a stationary air quality monitor on Amason sells for US$200+!  This item's power supply is not auto-powering as mine.

Is it better in the form of a Chest Badge?

 

Wearable as Badge or Wrist Band can promote itself in public!

 

I want to hear your valuable suggestion.  laughenlightened

I'd have thought so - it won't be on the wearer's skin then, will it?

 

But it's still very close the wearer & clothing - which could still affect those readings.

 

Surely, you've prototyped this ... ?

Yes, on users' clothes surface.

 

Power supply parts are on the way to me.

 

There are many reference designs about air quality monitor for me to copy.

 

Then, I will have a prototype very soon.

 

Is US$100.00 per piece possible?  I must make its quality very high so as to claim a higher price!

It's your project - you need to do the market research ...

 

Are you talking US$100 as the material cost? Or built unit cost? Or retail price? or what ... ?

 

If it's retail price, as you were asking about UK approvals, do you really mean GBP 100 ?

I think my badge should be large enough so as to prevent kids from swallowing it.  cheeky

 

If my product can get a UK Q Mark, I will sell it for US$100 per piece!  1000 pieces will sum up to a small fortune!  laughyes

 

Indians can do the appearance design.  Taiwanese is #1 at electronic circuit design!  Both are close to me.  Shipping cost is much lower!

 

I am more confident now than myself last year!  yeslaugh  Thank you for all your opinions.

 

 

Next project design is on the way now while parts of first project are the on way.  yesmail

But don't forget you will have to pay for design[1], materials, manufacturing, packaging, shipping, support, etc out of that before you make any profit ...

 

EDIT

 

[1] I should say, "design and development" - and that includes:

  • Mechanical - both the unit itself, and all its packaging;
  • Electronics;
  • Firmware;
  • App.

Hardly a small fortune--$100000, you could earn just writing software for maybe 9 months

Maybe you will make $20000 on the sensor, and even that is questionable.

Of course they said the same thing about the Ring doorbell!!

In consumer electronics you can basically bank on BOM needing to be no more than 25-30% of retail and the manufacturer might take 5-10%. Other pieces of the pie pay for 

 

sales tax

retailer profit

distributor profit

duty

shipping

manufacturing

tooling

accessories 

manuals 

marketing

manufacture LOP

BOM

 

If you want to make a large amount become either the government or the retailer. The government levy the sales tax (and maybe import duty). For example in UK something that sells for £100 ends up paying £20 to the government in VAT (sales tax) and maybe £4 more as duty when it was imported from Far East manufacturer. If something sells for £80 ex VAT then the retailer probably wants 30% profit so he might take £24. So the distributor might sell to him at £56. That distributor will likely want 10%+ so he takes £5.60 which means he buys in at £50.4. You might take £5..10 of which maybe half goes on marketing/manuals/boxes/dev costs/etc. So it needs to be landed for about £40 but remember that import duty. A container on a 6-8 week shipment from the Far East (worse, air freight!) is another cost to borne. Then manufacturer maybe takes £5 (perhaps less) for LOP which basically gets you to around that £30 BOM cost.

 

At the end of the day your "cut" was £5. Consumer Electronics is a cut-throat game. You have to be shifting 10's of thousands, perhaps 100's of thousands or even millions before you get to buy the yacht!

For instance, fackbook was for peeking girls and boys secret relationships.  Then, it turned out to help revolution.

 

And now, it is a strong tool to control speech freedom.

Just take the world of synthesizers - yeah there are still people tooling up and laying down circuits to make traditional hardware devices but the general push these days is to "virtual instruments" in the form of VST. Developers can make any number of those with a single software development kit. If making physical devices you have to commit (and try to track down) large stocks of physical components at your own risk. For virtual you just send out another 50 license codes or whatever.

 

An interesting company is "Arturia" - half their business is physical equipment but half is virtual:

 

 

Of course if you make mobile phones or wristwatches or something you don't really have a choice (well you don't until Mark Zuckeberg's virtual "Meta" dream materializes and we all live inside his Matrix!)

Sometimes, I also feel similarly.  With a bunch of applications on a tablet, one can do a lot of things such as photographing, monitoring sound volume, compass, etc.

 

As to industrial applications, do you think whether LabVIEW is a good platform to build Virtual Instruments?

 

It only supports very few NI's own hardware and they are very expensive.  If you want LabVIEW to talk to 3rd party hardware, you have to program from zero; and most probably, the hardware are expensive FPGA.  surprise

I don't know how much this feature will cost you both in mechanical size and BOM cost (and from what I've read, I'll guess you don't either) but you should drop this one out for a wearable.

 

Instead of measuring the 450ppm background atmospheric CO2, you will measure something close to the 2% CO2 the human body generates during normal breathing.

possibly (probably?) also power consumption ...

 

Also note that some sensor may claim to indicate CO2, but they don't actually measure it; instead, they measure VOCs and infer CO2 from that.

The CO2 estimation will likely assume free air - so unlikely to be valid when worn ...

I don't know how much this feature will cost you both in mechanical size and BOM cost (and from what I've read, I'll guess you don't either) but you should drop this one out for a wearable.

 

Instead of measuring the 450ppm background atmospheric CO2, you will measure something close to the 2% CO2 the human body generates during normal breathing.

 

You remind me of a new add-on service - customise the firmware for big customer who buys 100, 500 or more, so my monitor fits their team's environment.

 

I can even add advanced physics content to my monitor - statistical distribution of gas density along gravitational axis!  COOL!!!

possibly (probably?) also power consumption ...

 

Also note that some sensor may claim to indicate CO2, but they don't actually measure it; instead, they measure VOCs and infer CO2 from that.

The CO2 estimation will likely assume free air - so unlikely to be valid when worn ...

 

Inference is a very trendy term - Artificial Intelligence.  I can name my monitor having AI ability!

 

 

It may be possible that my little sensor turns into a CO2 tracking Guided Missile with built-in AI ability?!?

 ??? I tried to order cup glass for guided missiles,Unfortunedly must be in some containers and that made in Java.My town glass manufacture no longer exist.

Huh?  Sounds like you need to order a cup of coffee cheeky

When in the dark remember-the future looks brighter than ever.   I look forward to being able to predict the future!

In front of the head.Must order in 20000 pieces or more with that specified half Curve of the glass.I already post It at the another thread...

Jeckson,

If you live in Indonesia, I would like to build cruise missile with you because there are many small islands in Indonesia for testing.

 

I know how to build missile:

  1. a warhead
  2. a gyroscope for maintaining Moment of Inertia
  3. engine
  4. chemical fuel
  5. Control Theory + guiding electronics

 

We can share the profit.  laugh

My design only for very low budget builder.

My Warhead only with enriched common chemical ingredients which were available at local store.

I'm just used 9 DOF and altimeter module

3.engine

 

I didn't used Jet kind of such at JPL or RAM jet,I just used low cost DC motor(stepper) for Fins control.

 

HKPhysicist wrote:

Since only propelant(solid fuel) then casting for propelant(solid fuel).

Compared of Full fledge of Cruise missiles with SBC like others who's already built.Not my design reached......Just with MCUs.

With only GPS and possibly with "Camera" for visual or IR seeker(that's why I needed special cup of the glass like #96).

 

It depend's of what purpose of missiles..(AAM,ASM or SAM) or Cruise.

Jeckson,

If you live in Indonesia

 

Since Hong Kong was part of China,Did CCP allowed you to built that kind of projects ?

How's to help you ?

 

Must I sent you via HF/SW for schematics ? With Digital SSTV like EasyPAL ? or at attachment..

 

Also How's to sent the .HEX or .ASM ? Did you had HF/SW receiver/Transciever ?

=============================================================================================

I'm liitle bit concentrated for portable terminals and communications control system.

Yes,Military parts are very provit and always corrupted in that..

Thank you very much

Compared with S-300/400 manufacture my design inferior to that kind of types.
