My PCB-Milling-Toolchain

DSC01802

PCB-milling is an interesting alternative to the traditional PCB-etching method, because it doesn’t involve chemicals and the mill can also be used to drill the holes an cut out the board. I think i t’s also faster (never did etching). On the downside, the process is not easy to handle and it’s hard to level the surface of the PCB precisely to get a consistant quality of the traces. I haven’t enough practise to tell how fast the tool wears out and how the costs add up compared to the traditional etching method. But I finally managed to get nice results from PCB-milling and like to share the setup with you by describing the toolchain I used. The tools are all open source, by the way:)

crazy experiments: motors, frames and propellers

  I got a crazylfie micro quadcopter for my birthday and love playing around with this remarkable open development kit. Yes, it’s not just a very small but powerful quadcopter, it is also comes with all the design files and the tools necessary to modify the software and/or hardware, which in it’s current state is already quite mature. Having said this, if you look for a ready to go quad copter with all cutting edge features – look elsewhere. While the hardware with it’s 10dof sensors, fast cpu and expandability is – considering it’s size – quite complete, there are still a lot things to be developed hard- but foremost software wise. But this is not a downside, because the product crazyflie is not exactly a quad copter, it is a quad copter construction kit with every bells and whistles whith a blog, a wiki, a forum with a whole quad copter construction community, inviting everyone to participate. And for that I’m just loving it.

pLamp

Hi, just want to show you a new project I’ve almost finished:
The pLamp

DSC08170

features are:
-3-channel brightness control (each two of the bulbs are separately dimmable)
-adjustable focus position via stepper driven mechanic (see pictures)
-wireless remote controlled (3channel brightness + focus position)
-remote can be hooked to a computer to control the lamp via client e.g. for
advanced disco-action-controlling;)
-most parts are 3d-printed, the rest of them are easy to gather
-6 Standard 5W Led GU5.3 bulbs

It was originally designed to be a living room lamp, but with color filters
(different color attached to each channel) plus a small disco ball, it think
it’s a nice disco lamp too:)
