PCB Dilling Machine Progress

By -
Yesterday we made some progress with PCB Drilling Machine. The CNC Machine is currently driven by Atmel 90C2051, but my plan is to switch it completely to Pinguino. But, for now, I can show you how the machine drills in the test set-up. Software is done (not production ready). Calibration of the motors and the drill is done. One more thing to do is to speed up the drill pull-out. Now the speed of the drill in the 'down' phase is the same as in the 'up' phase. More on that during the weekend when I hope to show you first Pinguino PIC18F4550 based PCBs drilled by Pinguino itsefl! For now, some obligatory YouTube videos of the machine in action (OK, more-or-less action): CNC PCB Drilling Machine - Overview CNC PCB Drilling Machine - Zoom Detail 2 bb4now, PMC

Pinguino as Voltmeter V2

Yesterday I improved the Pinguino as Voltmeter Python UI. The scale has numbers, the needle is read and there are some other small UI improvements. But the most significant change is that the widget is not repainted every 20 milliseconds. Now it is repainted only when needle moves. The Class still stays under 50 lines of code. There has been no changes to Pinguino Class. The new version can be found on pastebin . And here is the screenshot: bb4now, PMC

Pinguino as Voltmeter (Multimeter)

Well, today I managed to put up a little python script which uses Pinguino as Voltmeter. The script can be found on pastebin . It is quite short, but it implements two classes: Analog Multimeter for the nice Voltmeter gauge pictured below, and Piguino which abstracts Pinguinos USB interface. The driving Pinguino script is on  pastebin too. So, what you need is Linux with installed python, PyKDE4, PyQt4 and PyUSB. In order to install PyUSB you will ned libusb too. Just upload the Pinguino script to Pinuguino and run the python script and you should get something like this: Oh, and you should bring some current to PIN 13 (first analog input) on Pinguino. You can try to put a trimmer resistor in front of the PIN 13 on the breadboard an play with it to see gauge moving! That's all folks! bb4now, PMC
