My pockets are already full, but I'm still interested in adding new features. Video and mains power are my current challenge, and I'd like to know more about whether the Kettlepop module inside the Pocket Popcorn computer has HDMI or VGA support. Right now this is what I carry.

Right belt clip (from a scrapyard, looks like it was designed for the Nokia 3650):

1. Third Rail smart battery, integrates well with my iPhone 4S case and has microUSB out for other devices.

2. microUSB male to USB male, 3D rotating adaptor wire.

3. Thin microUSB male to USB female, to get power out of the Third Rail.

4. MicroUSB female to Mini USB male.

5. MicroUSB female to USB C male.

6. MicroUSB female to iPod dock connector male.

7. Lightning female to microUSB male.

8. Dock connector female to Lightning male (Apple OEM because smaller ones stopped working after iOS 8).

9. Kokkia i10s Dock male to Bluetooth, with track info and controls.

10. USB C male to HDMI female.

11. Headphones.

12. Bluetooth remote and FM radio with headphone port (Sony Ericsson MW600).

13. Triple retractable chopsticks (I use these more than you'd think!)

14. Mini pen (Zebra T-3)

Left belt clip (Speck Canvas sport):

15. iPod Video 5.5G, with DIY Converse sticker on the clickwheel.

16. Victorinox SwissCard (the scissors are so useful, though the knife was confiscated in Kuala Lumpur airport while transiting before).

I changed the iPod's hard drive for a Kingspec 128GB SSD, which gave me a lot of internal physical space. That's where I put the Linux computer, and more.

17. Toothpick (for lifting the iPod battery connector, fixing lost screws in friends' glasses, etc)

18. SD female to microSD male x2

19. 512GB SD with a backup of my laptop

20. PQI Air Card (shares SD over WiFi to my phone, so I can read camera cards).

21. MiniDP to HDMI adaptor (with the plastic case removed to make it smaller).

22. EspUSB Tiny WiFi keyboard that fits inside a USB port (please message me if you want to talk about manufacturing these)

23. CoreWind WiFi G25. The Linux computer! It has WiFi, USB host, and can install imobiledevice and mtp-tools to mount phones.

"Technical difficulties" that I can solve:

a. Eating (13)

b. Writing (14)

c. Opening envelopes (16)

d. Listening to music (15 + 11)

e. Charging your phone (1 + 3 + 2 + 4/5/6/6+8)

f. Mac to HDMI (10 or 21)

g. Copying your files from a computer (iPod as a USB disk, 15 + 2 + 6).

h. Having a backup of my files if my bag (with both my laptop and external drive) gets stolen (19)

i. Using an iPhone as a wireless microphone (audioGraph software for iPhone mic -> line out, then 9 to 12 to audio line in)

j. Using iPhone as a clicker, mouse, or Chinese/Korean/Japanese/Arabic/Russian/Thai keyboard on a computer without the engravings (22)

k. Copying files from USB to WiFi (23 + 1 + 3 + 2)

l. Copying files from SD card to WiFi (18 to 20 to 18 to 23, and 1 + 3 + 2 for power)

What I can't do:

m. Mac to VGA (this was a problem at a church in Taiwan)

n. iPad Lightning to VGA (this was a problem at a church in Switzerland)

o. WiFi to VGA (might solve m + n). Raspberry Pi Zero W can be configured to use AirPlay, and can do VGA over GPIO. EspVGAX is also interesting, but I'd have to paste text into the browser for every slide.

p. WiFi to HDMI (maybe with the OrangePi Zero 2 mini, which also adds Ethernet)

q. Mains and/or 12V charging (plugs are just too big though)
