cracked hand sets and loss of display

rdmmdr

if hand sets where made disposable like they should be then half the problems would go away and the cost would be cut in half.

what is required in a hand set, forget bmw specs what do you need.

lcd display cost 25.00 1 ea price
two reed switches .50 1 ea price
cable 35.00 belden teflon with added external cover
misc mechaniocal parts for reed switches 10.00 ordered in 25 unit batch
cables boot 2.00
resin to encapsulate 6.00
time to build 1hr. at labor rate of 70.00
total cost 149.00

while i know that a lot of money was spent on design work, if you own it and it breaksin the first five years then the design was bad. this is life support equipment and nobody seems to think that electronic failures are unusual. This is the site and the people to demand that that unit be produced have a min of a five year coverage for parts. And that is over night replacement with spares. anywhere, anytime.The true total cost of the electronics for any unit if it was designed right would be under 1000 with sensors hud twin diplays and twin controllers. ps deco has no cost for to manufacture of the unit the only cost is for verification of the software. which can be done on a laptop in about a week of sims. in a proper pressure pot. this is not rocket science. a fifth grader could program the controllers we use.

Put your LCD in there.... built for a 4x20, hole on the side uses a Fischer connector. If you want to get TRULY outrageous you could simply put a cable gland in there (just for the strain relief) and pot the entire contents... but as you can see, I don't think that's really necessary.....

Add at minimum:

research and development costs per unit $100
indirect overhead expense amortized into each unit per: $250
indirect overhead includes but is not limited to taxes, permits, marketing, insurance, employee salaries, legal, travel, real estate and vehicle leases, utilities, testing and manufacturing equipment, regulatory expenses such as CE, etc, etc.....

Dude, get busy and build a better mouse trap, the world will beat a path to your door.

there is a reason this stuff costs money, its difficult to design and build, maintain suppliers of parts, pay employees, maintain machines to do the work, train folks to assemble. Then how about some profit to be able to make a living, pay uncle sam, or uncle ivan and a little left over to spend time designing the next toy.

Drives me crazy for folks, who can only look at parts catalogs and add up numbers, to tell me how F'n easy it is to do something.

You're obviously an expert at R&D, manufacturing, and marketing, as well as a whiz at running a business. Why not do it yourself?

Argggghhhhh!!!!! Bloody Americans!!
Let's do the maths on this practice of parking cars on things.
Small compact car : maybe 2500 lbs
Surface area of housing (5 inch x 2 inch) : 10 square inches
2500 divided by four (one wheel only remember) : 625 lbs
625 divided by 10 : 62.5 psi
That gives you the massive test depth of 42 metres! And that's not testing the o'ring seal, which some might think is an important point.
Dude, the only way to test a housing is in a water filled pressure pot.

Car, what car, that photo only shows a wheel assembly sitting on the handset. My stuff gets treated worese than than just being loaded into the boat

i seemed to have hit a sore point here

while i do run my own business, industrial electrical and control/instrument shop. my bitch was the flooding problem/ cracked hand sets. everyone knows that cameras will flood. The disasembly required to change the film is an inhearent design requirement, but hand sets don't require disassembly. 95% of components made today are none repairable sealed units due to reduced packaging costs. what do you have to service in a hand set that requires opening it. and the more stuff you put in a hand set the bigger it gets.

that said, if the only business you are in is the manufacture of handsets, you are screwed. the market is not large enough to support the infrastructure. assuming fifty handsets every six months at a rate of 250$ per unit 25,000 $ per year gross. i would do it as a way to keep the guys busy durring slow time when i have them cleaning the shop and painting gear.

with an order of twenty hands sets i will make the first production run. you said put up or shut up so here it is.
