While I keep most of my notes and tasks list on my two server-based TiddlyWikis (free account with www.serversidewiki.com and ZiddlyWiki hosted on a free Zope server) I still keep a hipster PDA to take down notes whenever I’m offline.
The problem with making hipster PDAs is the difficulty in printing on index cards. What I did (in past sense because I have found a solution) was print on a letter sized paper several hipster PDA templates and then cut these out and paste these on index cards.
That was the case until I found PocketMod. The site allows you to create a one-page organizer that you can fold into a pocket-based planner. The printing is relatively easy – you just print on a letter-size paper and then fold the planner. The site offers a video instruction on how to fold the planner.
