Last week I have attended to Hernando Barragan’s 3 day Wiring workshop at ITU TBT Lab.  Unfortunetly I couldn’t do much with my Wiring board because of bad CPU (Powerbook G4) and OS (Leopard) combination. But last day I brought my Arduino board with me and in couple of hours I was able to connect Maxim’s 7219 (display driver) chip to my Arduino board. Originally I intended to draw a smily on my led display for the workshop exhibition but It was not gonna look good on a 7×5 matrix so I ended up drawing an anti-christ cross (:

Note. Hernando is planning to patch the sofware so Powerbook G4 + 10.5 or Intel Mac + 10.4 will be running Wiring software smoothly.
