I made the smaller pedal (pictured below) myself... the 'wood' is merely a spare shelf from an IKEA book case. Works well in this capacity.

As guitar effects are right to left (like reading Hebrew) Here is what is on the pedalboard from R - L:
(not in the picture but on the floor and first in line before the board:
- BOSS AW-2 Auto Wah [tan] - While not as extreme as a Lovetone "Meatball" (which I also have) the AW-2 is pretty versatile and sounds great.
- BOSS PSM-5 (power supply) [red]
- BOSS OD-2r Turbo Overdrive [yellow] - Edge used a OD-2 for Until The End Of The World during ZOO and POPMART tours
- BOSS PW-2 Power Drive (overdrive) [orange] - Edge used one on his smaller board for the 1997 Tibetan Freedom show and it appeared in his main rig on the Vertigo tour
- PSIONIC AUDIO 'Z2' (distortion) - You'll notice the familiar "BOY" album graphic. Lyle from Psionic Audio made 13 of these, sending one to The Edge himself. The Z2 is a copy of the old Guytone Zoom distortion that Edge used around the time of the October and War era.
- BOSS DC-3 'Digital Dimension' (digital chorus) [pink]- The DC-3 was sold from March 1988 to August 1993. The name was changed on later version to 'Space-D' to avoid a law suit. Luxurious sounding chorus pedal. It's like having a great digital rack mount chorus in a lil box. Good stuff. NAILS Andy Summers-like chorus tones.
- BOSS PH-2 Super Phaser (phaser) [light green]
- BOSS TR-2 Tremolo (tremolo) [dark green]
- BOSS RV-3 Digital Reverb/Delay [charcoal] - Can be used as a digital delay, reverb or combination of both.
Behind the row of pedals, is the Boss TU-2 guitar tuner. The orange Boss pedal that is also back there and not hooked up is a BOSS DS-1 Distortion.
So SEE all the guitar newbies... YOU TOO (U2) can make a pedalboard with ease... just a board, some velcro and some pedals... et voila!
The first piccy (above) piccy I took with my phone this evening. Phone cameras sort suck but it gives an idea of what is on the smaller board. I will take and post a better piccy once I get a digi-camera:
Why two different pedalboards? Here's the main BIG board...

Being the other/bigger one... although that one has diffent stuff on it now, that piccy is older...
..so yeah WHY two? Same as "WHY A LEMON"... "WHY NOT.
