ArrayCollection group filter help

-

hi, great forum , great help.

i have flex 3 believe new group function array collections, have not installed yet i'm 2/3rds through hugh project , wanted wait until done.

so in flex 2.01 , have array collection of complex data. array collection built form returned result set mysql. each object in collection event. these events 1 of 4 types , clarity call them event 1,2,3 & 4. each object in collection contains lots of other data user fired event, tstamp happened, quarter happened in, month , year event happened.

there hundreds of these events happen each month. 1 of displays wish show total event type month or quarter.

need show total number of event type 1, each month.
need show total number of event type 2, each month.
need show total number of event type 3, each month.
need show total number of event type 4, each month.

i can filter data, need calculate data. can via remote calls mysql , having sql sorting, make 1 init call mysql , sort array collection in flex.

i hope makes sense :)
i.e
for each event add event type total each month.
extract of array collection
[eventtype:1, month:3, quarter:q1, year:2006,user:x]
[eventtype:1, month:3, quarter:q1, year:2006,user:y]
[eventtype:2, month:3, quarter:q1, year:2006,user:y]
[eventtype:1, month:3, quarter:q1, year:2006,user:y]
[eventtype:1, month:4, quarter:q1, year:2006,user:y]

sorry double posted reason...

i have laptop dead motherboard . can remove components laptop , in anyway possible connect raspberry pi inbuilt display , keyboard on laptop ? (and touchpad if possible). (i figured remove components inside , fix pie inside , use extended usb cable , connect available usb ports respective holes in laptop skeleton, same headphone out ) . i'm noob when comes pi . on topic appreciated if screen lvds type may possible use screen installing converter board. this: http://www.ebay.com/itm/hdmi-dvi-vga-dr ... 3027&rt=nc need model number of screen , ask seller if work. or search ebay using brand , model number. assuming screen in working order..... back-light not burnt out etc.. other devices...... can used if have usb interface not part of motherboard. have make connector. raspberrypi

Smoothing Capacitor value?

hi everyone! i have question "smoothing capacitors". have 5v arduino project have 6 individual 5v components attached it. since need these running @ different times, wanted take similar approach of nick gammon's in helpful example (http://www.gammon.com.au/forum/?id=12106) , use few mosfets switch these little guys on & off individually (instead of regular arduino pins), while minimizing potential power surges affect microcontroller and/or components themselves. these components 5v, , have maximum draw of ~170ma when powered on @ same time. so, if used 6 different mosfet switches turn switch +5v power line on each component directed via arduino uno, wondering: 1. still use 1 capacitor (like nick did in example)? 2. capacitor of 100uf work, or should use bigger? my plan first test circuit mosfets & capacitor(s) using usb, , later on, moving project battery power. thanks in advance ideas & suggestions! quote these little guys what ...
