I found a SPST dim bulb tester on a website. It looks much better then the first one I built. Now I can test older equipment without worrying about frying anything at power up. How many of you use this type of tester?

Re: My new dim bulb tester
I do sort of.... Mine has sockets for plugs instead of light bulbs.... It also has a ballast bypass and ground lift switch. Its also rated for 20 amps...... It's not always used to protect the load, but to protect the wiring in the walls when the load burns up

Excuse me while i do something dangerous
You must have a sad, sad boring life if you hate on people harmlessly enjoying life with an animal costume.
Sometimes you need to break shit to fix it.... Thats why my lawnmower doesn't have a deadman switch or engine brake anymore

I use it with my isolation transformer, GFCI, when I do any repair works.Last edited by budm; 02-26-2016, 04:56 PM.Never stop learning

Re: My new dim bulb tester
I have one too, thanks to Bud. I have a transformer, which still needs some repair. It was dropped and some stuff got broken in it(the rotor part, which I had to machine a new one). Still needs new brushes.Comment

I replaced the bulb only on my Toshiba DLP The bulb is a TB-25. This is the first time I've done a bulb only replacement. Supposedly there is a timer module that needs to be re-calibrated or reset. I don't know where the module is located. I see some vendors selling the bulb with the housing stating module included which leads me to think the module is located inside the enclosure the bulb mounts in, but I didn't see it. Maybe it's inside the plug attached to the bulb?
Anyway - I am seeking information on how to reset this so called module so that the lamp will operate. Apparently... -
Hi,
I have a LUMIMAN Smart Bulb that suddenly stopped lighting one day. The bulb is still detected in the app, but won't light. I've probed around and nothing seems to look off with any of the diodes, caps or resistors. The Bluetooth/Wi-Fi module seems to be working as it's still detected in the app. I even tried deleting and re-pairing the bulb (it didn't light, but I was still able to follow the pairing instructions), it re-paired fine, but still no light.
In diode mode, the LEDs all light up when probed so I'm guessing this means the LEDs themselves are OK. I was expecting... -
I have a pioneer dvl-909 LD/dvd player from 1998. It has a light on the front panel that lights up when you play a dvd. I removed the bulb and it appears to be a tiny incandescent bulb. Its measures "open"/dead and the bulb is black like it's blown. The socket it fits into measures 5v. I've looked up the schematics and there's no indication of the amperage. I don't want to spend any money on new parts, but I have a pack of like 100, 3v, 20ma LEDs and I have various resistors.
Is there a way for me to determine the amperage going to the old dead bulb with my multimeter?

Hi folks!
I have some kind of memory problem on Lenovo laptop. I was initially able to install windows after several tries since the laptop did freeze in middle of those attempts.
Eventually I discovered that it was related to moving the laptop.
Later on it even stopped booting unless I pressed around the memory slot. (no keyboard LEDs only power button responds)
If I remove the RAM I get the beeps that RAM is missing. Inserting the RAM there is silence and it will not boot most of the time. No picture.
I removed the board got one of those memory slot testers... -
Hi friends
I have reverse engineered this tester, schematic is attached and is complete except for capacitor values. These testers annoyingly have no model number but they are the ones you find on the first page of just about any website if you type in "18650 4-channel tester". There is also a 2-channel variant and a newer 8-channel variant. They are very cheap (about £15) and can measure voltage, current, internal resistance and capacity. They have a multicolour display for all these statistics. They also have terminal blocks so that if you want to use a breakout board...
