BF20L motor brushes, Links, and Purchases

Yes, it’s been a lazy week at the shop (not at work). I got my motor brushes yesterday, though. And the mill now runs better than ever. The first time I ran the motor (at the lowest speed), there was a periodic ringing sound, and I could tell it was some sheet metal hitting some other metal (cooling fan?). We (Pamir and I) opened the motor only, and this time I removed the can (naively, I had thought it was somehow mounted to the bottom, but it was the magnets), and I was right, the cooling fan was warped. I fixed the blades with my hands and a flat head screwdriver, and closed back the motor. I, of course, had to reinstall the motor brushes.

Optimum BF20L Motor Brush Problems

As I wrote in my previous posts, the brushes of the motor are gone, and I need to get a pair or more soon. So, I decided to remove the motor in the mean time. Here are some pictures of the motor and the mill during the disassembling process.

8 x 8 Laser Matrix for Fun – Part I

As I decided to replace the metal brackets for the motor mount, and didn’t have the proper parts, I worked on another project last week. I got some 1.5 mm stainless steel sheet today, though. I also got a new dial indicator, since Pamir knocked over and broke the one I got last night (It’s ok, it wasn’t no Mitutoyo anyway. I could have also turned the base magnet on to avoid it).

Commodore 64 MOS6581 SID Based Synth / Sequencer

Here’s another Instructable from a long time ago. It was also featured there and brought me some months of free pro membership. I’m just putting a copy here again. Another lazy day, all pictures in one gallery. Right click and view image on FF, for real size.

PC Interfacing a GameBoy Camera

This is an Instructable I wrote a while ago. It was featured there and brought me some months of free pro membership. I’m just putting a copy here, since I got my own blog now. Some schematics here  (the PIC Mother Card) are very old and crappy. I didn’t know much about PCB design then. I’m a lazy ass when it comes to web stuff, so I put all the pictures in one gallery. Right click and view image on FF, for real size.

Religion ofO Marvel! a garden amidst the flames.
My heart has become capable of every form:
it is a pasture for gazelles and a convent for Christian monks,
and a temple for idols and the pilgrim’s Kaa’ba,
and the tables of the Torah and the book of the Quran.
I follow the religion of Love: whatever way Love’s camels take,
that is my religion and my faith.

Blog Site Problems Fixed

This site has been on and off for the past couple of months. It was because I had problems getting my host (actually a Linux VPS in NY I use for other purposes) and my domain (from another provider, who used to be my host, as well) work together. All my fault, I was lazy and careless, and I was looking for the problems in the wrong places. I think it’s all fixed now. Hopefully I’ll get more visitors soon.
