I'm pretty sure you are right. Toner goes a long ways. The few laser |
| 28 |
printers I have dealt with also last longer than ink jet stuff. Right |
| 29 |
now, I have a large gob of ink under the cartridge where it parks. I |
| 30 |
figure temp changes are making it have just enough pressure at times to |
| 31 |
squeeze some out. At least it still prints, for now. |

I used to make PCBs by hand. I would draw with a pen or use dry |
| 34 |
transfer sheets to make my circuits. Once that was done, and checked |
| 35 |
about a dozen times, I dropped it into the etchant. A little while |
| 36 |
later, out come the PCB ready to drill and put parts on. Those little |
| 37 |
drill bits are kinda cute. lol |
| 38 |
|
| 39 |
From what I have read, I can print the PCB layout on paper and then use |
| 40 |
that to transfer the circuit to the PCB which has a photo-resist coating |
| 41 |
on it. Or whatever that is called. I've never done it but from what I |
| 42 |
read, it is the way to do it home style. If a person needs a lot of the |
| 43 |
same board, send the files off to a PCB maker and let them run them |
| 44 |
off. I've been told there are a few places in China that does one heck |
| 45 |
of a job on them even in fairly small quantities. Price isn't bad either. |

Most likely my first project will be a new adjustable power supply. |
| 48 |
After that, a fence charger to keep deer and wild hogs out of my |
| 49 |
garden. It's either that or a bullet. o_O |
