Hello, I'm JJ.
I build small things in my spare time — most of them for children learning about money and computers, one of them for a hobby I've had far longer.
For children
Three sites hosted by Pip, a red panda. They're free, there's nothing to install, and none of them ask a child to sign up for anything.
Screening Room watch.chanjayjay.com
Short episodes for ages 4 to 7 — what to do with your ang bao money, why we save, what it means to share, and how a computer follows a set of steps.
Pip's Playroom play.chanjayjay.com
Games that teach how to think in steps. Younger children put Pip's instructions in order and split pocket money between spending, saving and sharing; older ones write real code and read the real error messages when it breaks.
A book starring your child books.chanjayjay.com
Type a name, pick somewhere for it to happen, and a minute later you have an illustrated picture book with your child in it — about being brave, or starting school, or a new baby at home. Yours to download and keep.
Collecting
Two collections, and the small tools I built to keep track of them.
Banknote Collection gallery.chanmoneychan.com
A catalogue of my own notes — the Orchid, Bird and Ship series, portrait notes, and the serial numbers worth a second look. It reads the details off a photograph and writes them up.
Fountain pens
Pens, inks, and which pen is currently inked with what — for a handful of friends who still keep track of it on paper. No open list of pen models and their nibs exists, so we are writing one down ourselves.
