-A good general purpose N-channel enhancement mode MOSFET in the 200-800 mA range to go with the P-channel one. Generally something that can be switched on by logic and drive IR LEDs and the like.
-The adafruit parts library has the [[http://www.fairchildsemi.com/ds/FQ/FQN1N50C.pdf|FQN1N50C]] ([[http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=FQN1N50CTACT-ND|Digikey]]), with an Vdss max of 500v, Idm of 380mA, but a Vgs(th) max of 4v.
-Poking around at Digikey, I found the [[http://www.diodes.com/datasheets/ZVN4206AV.pdf|ZVN4206AV]] ([[http://search.digikey.com/scripts/DkSearch/dksus.dll?vendor=0&keywords=ZVN4206AV-ND|Digikey]]), with an Vdss max of 60v, Idm of 600mA, and a Vgs(th) max of 3v.

-  * I would like to see information about trim resistors/potentiometers.
-  * I'd like to see an extra column for the various electronic components with sources for Eagle Libraries that have the part/footprint for that component.
-      * Thats the plan...we have to get more info in first :)  --- //[[limor@ladyada.net|ladyada]] 2010/01/31 12:05//
-Switches and matching caps, which make projects look so much more //done// than normal tactile switches...:)  Also maybe "key" switches which are taller and have a more polished look to them
-TC4428 mosfet driver, for boosting current or inverting polarity to mosfets,etc directly from a microcontroller.
-Optoisolators, for the ultimate in protection for a microcontroller output (classics for MIDI inputs: PC900/6N137).
-I'd like to suggest the 65(c)02, just because it was a big game changer, and because i LOVED programming it in machine language (4C:JMP - Absolute Jump - yay!)
-MAX232/233 for serial RS-232 comms. Also FT232RL
-MAX7219 for single colour LED matricies
-LM386
-*14 under either logic or timers:  a single schmitt inverter and an RC network make a cheap and easy oscillator  [[http://www.fairchildsemi.com/an/AN/AN-140.pdf|(page 5).]]  Charge the cap with a transistor and use a diode to dump the cap to the inverter's output, and you get a wide-range VCO.  Wire all six inverters in a ring with caps between Y3-A4/Y6-A1, drop resistors to ground at A4/A1, and tap Y2/Y5 for a complementary, non-overlapping clock.  Any of those three applications should have a total parts cost of less than a quarter.
--compatible DC/DC converters: LTC1044 and LTC1054 (switching frequency outside of the audio range, the second one more robust to high input voltages)
-Multiplexer (eg for scanning a lot of pots...)
-PCB pots (eg P3K1103-ND on digikey, alps)
-Your transistor section doesnt have any mosfets. What through hole mosfets are good for prototyping?
-  * 2N7000 is a very common N-Channel TO-92. [[http://www.fairchildsemi.com/ds/2N/2N7000.pdf|DATASHEET]] -Brett W. 3-6-2010
-  * IRFZ44 for more power N-Channel TO-220.  [[http://www.irf.com/product-info/datasheets/data/irfz44.pdf|DATASHEET]] -Brett W. 3-6-2010
-  * Also search for the P-Channel compliments to these, and research logic-level MOSFETs. -Brett W. 3-6-2010
-<del>A list of the board houses (PCB MFGs) that you and others use. -Brett W. 3-6-2010</del> [[http://www.ladyada.net/library/pcb/]]
-A second vote for reliable linear pots, rotary pots and quadrature rotary encoders for use on front panel UIs, with caps and knobs that fit! Sorting these out has always been an expensive hit-and-miss task of buying and trying.
-Page http://www.ladyada.net/wiki/partselector/header - I suggest adding these links to 4UCON Ref (Only Digikey Ref for the moment)

-I was a bit confused when the "crystals and clocks" section didn't have any clocks, only to find them later under "integrated circuits".  Seems to make more sense to call that section "crystals and resonators" or just "crystals". --- //[[kevin.granade@gmail.com|Kevin Granade]] 2010/09/24 12:05//
-  * Logic-level MOSFETS, especially power MOSFETS
-  * Multi-turn linear pots
-How about solder paste, flux etc. ?
-I was looking for something like a breadboard, but a PCB board.  I wanted to take my project from breadboard to PCB.  I found one from BUSBOARD Prototype Systems, the SB400.
-I would like to see suggestions for relays or other devices for controlling household AC devices with something like an Arduino. (e.g. a "Clapper") - hghowe 03/26/2011
-      -Check out the power switch Tail, it does about like what you want, it lets you use a small current from something like the ardunio, with a Relay and that stuff inside, tucked away saftley ( here: [[http://www.adafruit.com/index.php?main_page=product_info&cPath=44&products_id=268L|Power Switch Tail at Adafruit Store]]
