Homemade Bicycle Repair Stand. Jake Khoun’s DIY bike repair stand looks easy and sturdy. Just the ticket, now that the roads are getting wet and I’ll need to clean my chain and running gear more often.
First, I verified the 24V transformer’s primary is getting line voltage.3 Then, checking the secondary, I found no voltage. I tried again. I pulled it out of the furnace and tried again. Still no dice. I guess I could have just measured the impedance across the secondary and discovered the transformer was bad4 and needed replaced.
Unfortunately, by the time I discovered this, the local appliance parts and electrical supply stores were closed for the week. Home Depot and Lowe’s were still open but neither has a matching transformer. Looks like it will be next week before our HVAC is working.5
I’m concerned: if I replace the transformer, is something else wrong that will kill the new one? Or did the transformer just die of old age? I guess I’ll find out.
Fortunately, the weather is getting cooler.6
1Essentially, this is rule #1 of debugging: is it plugged in? 2Ya gotta love the Transonics wiki’s disclaimer/warning/license: “The following information may have errors; It is not permissible to be read by anyone who has ever met a lawyer. Use is confined to Engineers with more than 370 course hours of electronic engineering for theoretical studies.” I’m still trying to figure out how this applies to me. 3Yes, this means the breaker was ON and the furnace cover was off. If you’re thinking of using my post as a guide to debug your HVAC system, you should read the preceding footnote. 4It was shorted. 5Does this help? ;-) 6But I don’t have forever; the heat doesn’t work either.
It was time to replace the lamp on my nightstand. So I made one. Although it has a switch hidden on the bulb socket, I plug it into a touch switch module; I can touch the pipe base anywhere to control the light.
I think it looks a little better than the PVC pipe lamp I made some years ago.
One more major appliance has yielded to my handyman skills.
I spent all Saturday night and most of Sunday draining the drum, removing the drain pump and motor assembly, and then re-installing everything, to have it work only some of the time,1 and even then, not for long. I was able to eliminate kinked hoses, the backflow ball valve, electrical connections, and the control computer as being the problem. In the process, I learned about a filter I should be periodically checking and why smart appliance repairpersons wear gloves.
I also learned Suzi is much smarter than I in locating parts. I looked online, drove three hours, and didn’t get the part. Following Suzi’s advice, I made two quick calls, drove 45 minutes, and came home with the part. Thanks, Suzi!
After work, I had the offending motor assembly removed and the new one installed in less than an hour. It even works. :-)
