BS2 Jolts
Archiver
Posts: 46,084
Hey all,
Is the bs2 affected by strong physical jolts? I built a counter for my
paintball gun for how many shots I've fired, but everytime I fire it
turns off the unit until I switch off the pwr supply and then turn it
back on. The bs2 runs a 4 digit led display through a max7219.I have
checked my soldering and they are fine. Can anyone shed any light on
this?
Thanks
-Mike

At really high speed jolts, wouldn't there be a red shift of the electrons
if the stamp was moving away from you, and a blue shift if it was moving
towards you?

the stamp to debug a 1 every cycle of commands while running the counter
program to see if it was the stamp or the display, and it is the stamp
stoping. I guess its from a lack of power from this shift of electrons
you guys are talking about.(thinking out loud now) Maybe a simple fix
would be putting a cap in the circuit to sustain the stamp with power.
What size cap would I need? Thanks so much for your help guys.

I agree with Jon that there's probably some slight mechanical flaw in your
circuit that's opening the circuit and causing the Stamp to lose power.
You might, in fact, try a largish cap. (probably a couple of uF) next to the
stamp, to keep it alive when the circuit's open. Kinda kludgy, but it might
work.
Your best bet, however, would be to ensure the integrity of your hardware.
Put everything on PCBs, and put some kind of conformal coating on all of it
to protect it.

could be happening.
1) A sudden heavy current flow drawing down the voltage (watchdog should
reset the stamp).
2) A reverse high voltage spike (from some form of inductor/coil or
whatever)
3) Loose connection or cold solder joint that screws everything up when
jolted
4) Barely sufficient power supply that "drops out" when the extra load of a
count cycle is triggered.
What powers this counter, 9V battery? Four AAAs? How is it hooked up? Do you
use your own regulator or let the stamp do the regulating?
Best thing would be to put the schematic somewhere and let folks see how you
have it wired. A physical shock should have zero effect on this unless
something is loose.

size of the area where I installed the system until I make one with a
board house. I was just thinking, when I pull the trigger it causes the
interruption but the display doesn't turn back on as it should if it
were just a reset. I'm looking through the stamp manual and I can't find
any reason this is going on. I highly doubt I but could the Max7219
still be recovering from the power failure and misses the stamp
initialization sequence for it? Here is how I have everything connected
power wise anyway.
Thanks for your time.

small 6v camera battery going straight to the Vin pin. The counter works
fine when I just press the button. Ill check for a loose solder joint
etc...
Thanks so much.

By what mechanism are you detecting the shots? There are a few things
that
could be happening.
1) A sudden heavy current flow drawing down the voltage (watchdog should
reset the stamp).
2) A reverse high voltage spike (from some form of inductor/coil or
whatever)
3) Loose connection or cold solder joint that screws everything up when
jolted
4) Barely sufficient power supply that "drops out" when the extra load
of a
count cycle is triggered.
What powers this counter, 9V battery? Four AAAs? How is it hooked up? Do
you
use your own regulator or let the stamp do the regulating?
Best thing would be to put the schematic somewhere and let folks see how
you
have it wired. A physical shock should have zero effect on this unless
something is loose.

Sorry, can't read your schematic, text drawings get all garbled.
If you're powering the LEDs from the stamp's Vcc the LM2936 regulator on the
stamp has a maximum current of 50mA. The 7219 has a maximum draw of 320mA
with 8 digits and periods all lit. If you aren't using the periods then it'd
be around 28/64*320=140mA (rough estimate). The regulator would (hopefully)
shut itself down via the overcurrent protection.
If you're putting the power direct from the battery to the LEDs, make sure
your battery can handle the output. If you're drawing too much, the voltage
can drop a bit and you have precious little room for it.
The regulator on the stamp has a dropout of 0.200V at 50mA. This is added to
the regulator's actually voltage output (its not always 5v bang on). If the
regulated voltage is exactly 5V, you have to supply it with over 5.2 volts
or it won't work. If the regulator output is at 5.15 volts (3% tolerance
remember) then the battery has to stay over 5.35 volts. Put a meter on the
battery and see what its output is while the circuit is working. You might
be riding the thin edge.
Other than that, I can only think its a not-so-good connection...
Are you using an OEM Stamp or the "open" kind? If you are using the cool
looking Stamp with all the SMT components showing how are you protecting
it from shorts against any other metal parts?
I recall a thread here a while ago that if you touched the resonator with
your finger you could stop your Stamp. You would have to power cycle to
get it back.
Just a thought.

Make sure your solder connections are done well. Without proper cleaning,
tinning and sufficient heat, its entirely possible to make a solder
connection that's only mechanical, instead of the eutectic molecular-level
bond it should be. These "cold" joints can conduct properly until some
vibration shifts the unit a bit. Then the oxide on the exposed surfaces get
in the way and causes a high-resistance connection, and circuit mayhem. Many
times, the problem will disappear for a while depending on temperature,
which causes expansion and contraction of this "mechanical" joint. When I
had my computer repair business, we used a can of Freon and a hair dryer to
alternately chill and heat circuit boards to isolate such problems. Freon is
expensive now (and environmentally dangerous) but there are safe chilling
alternatives. Also, putting your circuit board in a freezer bag and into the
deep freeze (put it in an anti-static bag first), getting it really cold,
then warming gently with a hair dryer can show if the problem is temperature
related. Also, we used Bic pen bodies (without the guts, of course) as
non-conductive probes to flex each lead and connection (again, gently) while
running a diagnostic program.
Again, real seriously...
As a side note, I once worked for a company that built parts for nuclear
missile guidance systems. One of the parts we supplied failed during a test
flight after the missile was launched from a submarine. This caused it to
make a hard turn, and head in a direction they definitely didn't want it to
go. Yes, the safety officer had to "terminate the flight " by detonating it
mid-air. Final cause of failure was determined to be a bad solder joint
caused by a build-up of gold in a solder wav tank. The gold interfered with
the lead-tin to copper bond in a proper solder joint, resulting in a
mechanical "cold" joint. This part tested properly in all the normal ways,
but when subjected to 18 months of vibration at sea, it failed at the worst
possible time in the worst possible way the only time that really counted.
Those guys were really mad we messed up their war games. Murphy was an
optimist!!!

Just FYI:
Try a mono-spaced font (i.e. courier) and turn off HTML reading of email.
Together these two things have made every ASCII schematic on the list
quite readable for me.

find that elusive problem. I will take note to cover my bs2 with a piece
of rubber to protect the exposed pins and traces. And last of all I will
test my battery, but not today because I'm getting my license today.
Thanks so much everyone who helped out.

Seriously now....
Make sure your solder connections are done well. Without proper
cleaning,
tinning and sufficient heat, its entirely possible to make a solder
connection that's only mechanical, instead of the eutectic
molecular-level
bond it should be. These "cold" joints can conduct properly until some
vibration shifts the unit a bit. Then the oxide on the exposed surfaces
get
in the way and causes a high-resistance connection, and circuit mayhem.
Many
times, the problem will disappear for a while depending on temperature,
which causes expansion and contraction of this "mechanical" joint. When
I
had my computer repair business, we used a can of Freon and a hair dryer
to
alternately chill and heat circuit boards to isolate such problems.
Freon is
expensive now (and environmentally dangerous) but there are safe
chilling
alternatives. Also, putting your circuit board in a freezer bag and into
the
deep freeze (put it in an anti-static bag first), getting it really
cold,
then warming gently with a hair dryer can show if the problem is
temperature
related. Also, we used Bic pen bodies (without the guts, of course) as
non-conductive probes to flex each lead and connection (again, gently)
while
running a diagnostic program.
Again, real seriously...
As a side note, I once worked for a company that built parts for nuclear
missile guidance systems. One of the parts we supplied failed during a
test
flight after the missile was launched from a submarine. This caused it
to
make a hard turn, and head in a direction they definitely didn't want it
to
go. Yes, the safety officer had to "terminate the flight " by detonating
it
mid-air. Final cause of failure was determined to be a bad solder joint
caused by a build-up of gold in a solder wav tank. The gold interfered
with
the lead-tin to copper bond in a proper solder joint, resulting in a
mechanical "cold" joint. This part tested properly in all the normal
ways,
but when subjected to 18 months of vibration at sea, it failed at the
worst
possible time in the worst possible way the only time that really
counted.
Those guys were really mad we messed up their war games. Murphy was an
optimist!!!
