VolLog #129 – Ebay Bussmann Fuse vs Genuine Bussmann Fuses DMM-B-44/100-R

If you remember Voltlog #117 in that video we analysed some ebay Bussmann fuses to try and figure out if they are fake or real fuses. The ebay fuses we’re way cheaper than anywhere else so that made me suspect they are not genuine.

It’s good to know if the ebay fuses are real or not because they are selling allot of them and people might be relying on these to perform as required when in fact they might be out of spec. For the average bench user which only occasionally goes up to 240VAC it might not be an issue if the fuse is slightly outside the specs but if you are probing some high energy circuit and relying on the ebay fuse to perform according to the datasheet at it is not then something serious might happen, like the multimeter could explode because of a high energy discharge or it could simply damage the meter which is to be avoided.

Voltlog #120 – Mini DC Power Supply Review

So I guess a gadget like this is worth 10$ because you could replace that linear breadboard power supply with a more efficient one, which will give you voltage and current display as well as adjustable output.

Here are some images I took during the teardown of the mini power supply:

Voltlog #66 – Cheap NiMH Rechargeable Battery Testing

If you were following my InTheMail videos you probably seen these green rechargeable batteries that I got from ebay quite cheap, I think they were like 50 cents a piece. I got 4 pcs in AA size and 4 pieces in AAA size and little did I know about how crappy these could be.
