Slowly but surely this project is nearing completion. This weekend I assembled the base and gantry. The remaining electronics and stepper motors have shipped and should arrive this week. There is still a lot of minor assembly and tweaking to be done but it is finally starting to look complete. My good camera was low on battery so I only have grainy phone pictures to share.

AVR DDS Function Generator
October 21st, 2010I ran across this link via Hack a Day for an AVR based function generator. My workbench has needed a function generator for a long time and this looks like it would fit the bill nicely. Now to find the time to actually build the ting…
CNC router progress
August 9th, 2010I made some more progress on my CNC router project. Here are all the base pieces put together in a mock-up of what the final result will look like. The black pipes are what the gantry will ride on.
PCB for usbSimRadio prototype
August 4th, 2010Tonight I etched a printed circuit board for my Nav/Com radio prototype. The toner transfer method using photo paper and a laser printer gave acceptable results. The board would have turned out better had the copper clad board I used been in better shape. It was a good deal on eBay and was a little rough with several pitted areas. A scouring pad cleaned it up pretty good. Below is the board after etching (ferric chloride rubbed on with a sponge, about 3 minutes to etch) and drilling.
I inserted the 7 segment displays to check alignment. This project has been delayed again and again so I can hardly wait to light it up.
Here is a paper printout of my panel design to give an idea of what the finished product will look like. The display opening will have some kind of frosted or tinted plastic diffuser.
