[Newtonn2] dropped a tip in our inbox this morning that made us quite happy. This is a step by step build of a small form factor LED based projector. While the size may not get some of you too excited at first, those of us who have built projectors before know that home made ones are usually quite large. This one is roughly the size of the small office projectors you would see in a large retailer. He’s using a 30 watt LEd for the light and we didn’t notice a lumen measurement anywhere, but it looks bright enough to be watchable. Pictures usually turn out dark, so in person, the projection probably looks more bright and crisp. Now he just needs to find a high definition LCD that size.
How do hardware geeks carve pumpkins? With giant home made CNC mills, that’s how. Using the open source CNC kit from Lumenlab.com, they converted a photograph into g-code, then fed it to the machine. After about 20 minutes of pumpkin drilling, they had this beautiful jack-o’-lantern. We are definitely jealous. Keep up the good work Lumenlab.
