another of these things that should never break: the cover of the car's fuel tank pipe

all cracked and broken cover:

shiny & fixed cover! amazing what you can fix with a warm iron!

Note i would not be too worried about it unless it would not have been a problem in case it closes badly and forbids the proper locking of the muscle car :D

kit velleman k8055 (or vm110) - coupling with rc servo

step 1:
K8055 velleman card working! :)
using K8055_full_demo_app-1.2.0.1



step 2:
control rc servos through the k8055 using the following 0-5vdc to 1-2 ms pulse over 16 ms cycles. (ideally 19ms but hey nothing s perfect)


sheme:
components calculated from:
http://www.daycounter.com/Calculators/NE555-Calculator.phtml

note a red Led has been inserted to visualise power in serie with a 390 ohm resistor; final dual circuit impedance is close to 420 ohm due to the 2x 1Kohm variable resistors etc..., I also added an electrolytic condenser of 470 µF for power filtering.

Dual 0-5 vdc to RC servo signal converter

in bi-servo configuration: with a 1A 5vdc alimentation not delivering enough power, peak power consumtion by 1 servo induces the move of the other servo (the well known low battery power effect). Using a battery with its RC regulator showed much decreased interferences. Hence it would be good to have an alimentation of 5vdc 5A minimum (stable alimentation can be achieved easily using several parallel power regulators 7805 with a common cooler).

edit as asked on comment:
top view (from component parts)

little help for those that want to build the circuit on a pre-drilled plastic support. don t forget to connect legs 4 and 8 of the 555.
watch out, all crossings should not be connected, check on the sheme above to make sure. The connection to the servo is depending on your device's plug, it needs signal, +5vdc and gnd.
good luck

how to fix a Krups balance that has a broken screen?

What, no numbers printed on the screen of the balance!!! oooooooooooppps let s fix it!

What i did: re-melt the connections of that little µprocessor (a lot!!) being carefull not to make shortcuts with some Sn-Pb melted metal. in fact i had discovered that pushing it made the creen parts work again erratically, that was a bit clue!

Still a few problems... lets melt the other side of the µprocessor too

It works!

the cause of the problem : the pad pushing on the µcontroller that got misconnected due to stress. i removed a bit of plastic... problem solved.

the small problem that was slightly &^ù*$^-'{[|\&& during the trip, and its solution :)

the stuck mobile home...

hummm.... what was the problem again? haaa maybe the next time it will be better to set the battery charger to charge mode ;)

Mazan avec pat & lp 4-8 sept 09

Ma petite soeur m'a invité à passer quelques jours en coup de vent dans la villa avec piscine qu'elle et son époux ont loué cet été à Mazan (près de Carpentras).

C'était l'occasion de se dégourdir les jambes et de défier mon beau-frère dans une large gamme de disciplines comme nous avons l'habitude de le faire :)



Roussillon, les ocres (minerai à base de silice et d'oxyde de fer, utilisé dans le temps pour fabriquer la peinture "ocre")
en sortant du sentier des ocres, LP voulait se moucher quand tout d'un coup son mouchoir lui a échappé des mains et a atterri juste sur mon pied alors que j'étais bien loin derrière! à bientôt la revanche pour ce coup tordu!









Les visites, Le sentier de l'ocre de Roussillon, la piscine!, le camembert frit (miam!)

hé zut il faut travailler de nouveau....

T-storms? really?
