Great little video, ilike the idea of the switch as you could turn it off quickly if there is a short detected in the tested circuit. With that said it was nice to see how the device also took a big load off the drill. It was a good demonstration how it also helps protect shorted circuits. Thanks
@@aroundtheshack thanks for the reply, I was going to build one this weekend with spare parts, but I like the way you did yours so I will go to the hardware store to get parts to make it look more like yours. CHEERS
This an excellent device ( I have made many , over the years ! ) .... also very useful as an input ballast for EHT transformers running gas discharge tubes ( they exhibit negative resistance ) ..... also highly useful to work out windings of unmarked transformers ... should you connect the full mains to the 12 Volt winding , you just get a very bright light ! .... ( tried - n- tested ) ...........
Thanks you for your video. Nice work! One comment. You may wish to consider re-titling your video. Why? Well, I clicked on your video based on the title however, as a viewer I never saw any of the BUILD portion of your ‘Build A Dim Bulb Tester’!
Well done and nice set up. I am going to build one and I like your wiring arrangement. Question Please: Where did you buy your isolation transformer and do you remember the approximate cost? Thanks. (Gave you a sub)... Phil NYC Area
Hi, thank you for the complement. I got the transformer from amazon. it is a "Jameco Valuepro ITR300 Power Transformer, Isolation, 120VAC, 300Va, 3.2" W x 4.6" D x 4.2" H" currently unavailable. Try Google, but good luck. I couldn't fine another one as of this day. :-( Let me know how the dim bulb tester build go.
@@aroundtheshack I'll keep you posted. If you find any isolation transformers I should check out, please feel free to send the info. Thanks. Phil NYC Area
Probably a stupid question, but can you have a low wattage bulb that would blow up, or is the wattage way higher than most electronics components consume? Also, do you use software for your layouts and schematics or is that free hand? Thanks
Hi Gary, Sorry for the delay... The wattage of the bulb should be greater than the DUT. If the bulb wattage is lower, the worst that will happen is the bulb will light full and the DUT won't power up properly. The bulb won't ever "blow up." Most of the devices I test run about 25W, so I use a 60W bulb. As for the drawing, this one is freehand. I use LTSpice for electrical drawings and design.
A good video. But two things... many times your voice trails off weak as you come to the end of a statement. I had to keep going back and cranking the volume to pick up those last few important words. Also, you supply the circuit diagram and beautiful pictures of the parts and the final assembly, but you don't really build the tester. You kinda dance around it. I enjoyed the video, but it's not what I expected based on " BUILD a Dim Bulb Tester. Please don't be offended ~ of all the Bulb Testor video's I've watched, I think your design is the best.
Hi Carl, Thanks for watching and no worries, I’m not offended. Sorry about the sound. This was one of my first video attempts. I promise, they got better. (I have better mic’s now) And unfortunately, there is no way to fix it. I chose not to video the actual building of the tester because that would make a 2hr video… bjoring (lol) and anyone that is actually going to build this already knows how to strip wire and turn a screwdriver. Well, that was my reasoning anyway.

Hi Luc,
Thank you for your kind comment. I am glad you enjoyed the video. Let us know if you build one :-)

Thank you for the video. I clicked on this one, it was to the point and not 25 minutes long.
