| I appreciate all your suggestions. Is there a website you can suggest that has more information on this stuff? Also, beside Jameco, what are some othe good places to buy parts? Thanks, Tom (16 years ago, 25-Oct-08, to lugnet.trains, FTX)

| (...) Hey Rob, It would be safer to place a regular doide in series with this if the voltage is going to be reversed some of the time. But the circuit shown in the link handles reverse voltage up to 9v fine. The LED acts as a reverse protection (...) (16 years ago, 24-Oct-08, to lugnet.trains, FTX)

|
| (URL) I am very proud to announce that I have converted to 8-wide trains. The UP Western Pacific is my favorite of the three that I have built so far, but I have several more that have finished the design phase and will be building over the next (...)

| (...) I outlined a few of my thoughts in a post awhile back (I just found it - wow, that was more than three years ago!) Most of it still seems relevant. However the newer specialized car pieces such as the fender arches and hoods have altered my (...) (16 years ago, 24-Oct-08, to lugnet.town, lugnet.trains)

| (...) Great idea. I hadn't thought about whether Tom was going to use a variable speed control. I just assumed batteries for some reason. Have you had any brightness issues with the seemingly low 15mA output for multiple LEDs or are you hooking 1 to (...) (16 years ago, 24-Oct-08, to lugnet.trains)

| (...) If the voltage is going to vary, don't use a resistor as current source, consider a current regulator instead. That way the LED stays brightly lit over a wide voltage range without getting burned out at max voltage. This works for one or more (...) (16 years ago, 24-Oct-08, to lugnet.trains)

| TexLUG was invited to participate at Maker Faire 2008 in Austin, Texas this past weekend. We're not the first LUG to display at Maker Faire, but this was our first time, and we walked away with not one but two "Editor's Choice" awards for our (...)
