Diary of a Technocratic Anarchist

I had gone to considerable trouble to make sure that I sited the bolt holes in the MDF {medium density fibreboard} print table properly. T...

I got the last of the y-axis brackets printed and light mounted. It looks like the print table with be 420x420 mm.  I've des...

Having had good experience with the Rapman's PIC32-based controller, I decided to stick with that MCU for my new printer.  As I mentio...

I was finally able to finish making the connection between the z-axis lead screw and the cable turnbuckle for the z-axis positioning system....

With the completion of the gear pair last night, the connection between the NEMA 23 and the Z-axis lead screw is complete. That milest...

Few experiences are more satisfying than a creating a useful device of great intrinsic beauty

It took me 10 hours and fifty minutes to print the first print table bracket and I got a few measurements wrong, but it appears that the c...

Back at the beginning of 2006, before there was even a Darwin, eD Sells at the University of Bath was designing Darwin's predecessor, A...

Printing solid, structural objects is quite an art.  As I mentioned earlier, I am harking back to a very early effort that eD made with A.R....

Actually, Darwin never really left. Despite all of the hoopla about Mendel, a very robust Reprap machine which is virally spreading ...

This morning, I bought the linear shafting; 16x2ft 8 mm diameter segments and the linear bearings; 24x8 mm linear bearings. The first tes...

Fired up the development board and it fell into a roundabout of pics. Not bad for a little 320x240 display.

My PIC32 development board arrived today! I also got a trial stepper motor controller with it. The development board looks as goo...
