As you can see from the post below, I’ve been experimenting with Perler (aka melty) beads. The starter kit I bought didn’t have enough black and white beads to finish the QRCode and I didn’t want to buy any bulk bags until I’d proven the concept so everything waited until today, when I swung by the local craft store and bought a mixed refill bag. Voila!
I don’t think my cell phone camera/scanner SW copes well with low-light conditions – it wouldn’t scan in late afternoon ambient light and I had trouble scanning a QRCode in a movie theater lobby (dim) recently. At least, I hope that’s why scanning was temperamental; more testing wll be done tomorrow.
