This paper presents a complete portable laser-based projection system using two one-dimensional magnetic actuated MEMS linear scanning micro-mirrors. Dedicated high speed electronics was developed to drive the MEMS, detect the mirror scanning position at any time and synchronize the two mirrors and the laser pulsation. The achieved projection system head is 3 cm 3 and is able to project static images and videos with projection size of 50 cm diagonal at 50 cm distance with 32x32 px resolution, the resolution is only limited by current optical setup. The circuit building blocks itself can project image with resolution up to QVGA (320x240 px), suitable for information display applications.

Grow-in-place VLS Silicon nanowires have been used since 2007 to produce accumulation metal oxide semiconductor accumulation field effect transistors. Since their inception, the in-template version of these devices has suffered from surface quality control whereas the extruded version suffered from control of growth direction. Both of these issues now appear to be solvable. However, doping control remains a problem due to the inadvertent doping of the VLS catalyst. Purposeful doping to overcome this inadvertent doping may be the practical solution to this problem. These devices may have display applications and their simplicity and small size makes them very attractive for sensor applications.
