Home made small form factor LED projector

[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.

CNC pumpkin carving

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.

Lumenlab’s new kit: Open source CNC


Imagine our surprise when we stumbled on the latest Lumenlab project: gantry style CNC. Until now the only time we ever invoked their name was for DIY projectors. The kit looks pretty interesting, and they’re taking pre-orders right now. It’s designed for a full sized router and you should be able to cut a 4′ by 8′ sheet with a feed roll. Even without, the cutting area is a large 26″ by 50″ and features 8″ of Z movement. Between their kit and an order from Online Metals, they’re projecting that you can build your own for around $1000. We’re definitely in when the final kit is released in June.
