    Enhance Your Multimeter Using a Polyfuse

    Yes and it will work great in such a environment, but it is best to state that it is not a good idea to do this on every multimeter. It works great in a area of low DC and neglect, but it doesn't enhance every multimeter and is risky. if someone were to follow this instructable assuming it will work for any purpose will find themselves with a fried meter quickly. :<Just because a few come with PTC out of the box doesn't mean it is good. There is very little control on multimeters so there are a lot with claims that aren't even remotely true. when looking for a good quality safe meter i found that majority of the sub 100$ meters aren't safe at all and plenty aren't truthful about their specs (don't trust Uni-T nor Voltcraft!!). Took me months to find one that fit my needs.Tripping of ...

Took me months to find one that fit my needs.Tripping of PTC is also a bit more complicated than just derating the current being equal to safer, it won't make it able to resist a transient any better. never assume a lower current rating = safer.I'm sorry if i'm sounding a bit critical, but when it comes to safety and protection-circuitry i find it important to mention the risks involved with modifying them.

    I wouldn't call the poly-fuse (or PTC fuse as i know them as) a enhancement for multimeters. The fuses in multimeters serve to protect the user above all and the old fashioned fuses are more reliable in that task. Polyfuses (or PTC Fuses as i know them as) are namely a bit slow in tripping and are more likely to fail catastrophically in the face of nasty current/voltage spikes. My own multimeter uses special HBC fuses designed to withstand getting hit with lightning!Now for low voltage DC circuitry with low power consumption and such a PTC will do perfectly fine, but the moment you start stuff that involves AC, higher voltages, higher current and such i wouldn't trust a Polyfuse at all. I prefer a multimeter that doesn't explode over one i don't have to replace the fuse of.Only when you...

  • Arduino Nixie Tube Clock - Version 1.0

    Ouch. that is quite a bit of a high price at aliexpress. would take 240$ to get enough for a clock. I think i'll just stick to designing my own modules. ^^;

  • Arduino Nixie Tube Clock - Version 1.0

    I know how you feel. Originally i wanted to also build one out of modules and such, but when it became clear that availability is problematic i instead went for designing my own modules.Eventually i hope to share my designs on instructables.

    It is unfortunate that the Module itself is no longer produced. Worse is that it isn't possible to reconstruct from schematic as the schematic they share seems to be of a 12v powered one rather than the more recent 5v.Really frustrating actually. Ive been looking at how to get 170v from 5v, but almost every 5v psu design out there is without a schematic.

    Mini Stereo Amplifier

    No problem. Electronics is a major hobby of mine (to be specific i have a passion for audio stuff like headphone amplifiers and retro stuff like Nixies and vacuum tubes) so if you need any help or want to know how to do something feel free to ask!! :)

    More of a showing of the project than a actual instructable.

    Mini Crossbow

    Checked and it is not. It is similar in design, however this one uses a different way of spanning the rubber band resembling a bit more like a crossbow.

    Mini Stereo Amplifier

    Hi. i know a bit about datasheets and Li-ion so i can answer your question!The datasheet says that the PAM8403 has a supply range of 2.5 to 5.5v. So you can power it directly from a single li-ion battery. Tough at 3.6v the power output is halved.if you really want to get a neat 5v for this and other projects then you can either use a boost-converter to get 5v out of a single cell or use a simple regulator to get 5v out of 2 batteries in series. The regulator is the most easy one as a single component can do it. For a boost converter there is the LT1308 and for standard regulator there is the ultra-common 7805.Slight warning: Li-ion is not the most safe of batteries. If yours doesn't have integrated security be careful to avoid short-circuit or discharging below 3v!!

    World's Simplest Electric Train

    My bet is due to energy comsumption. Between the battery terminals are 2 magnets with a negligable resistant and a Air core inductor. This project will drain the battery as fast as physically possible. Let me do a quick estimation. Let's say that everything together (battery,magnet and coil) has a resistance of say 0.5ohm (reality is probably a lot lower). at 0.5 ohm the current would be 3Amps and consumption would be 4.5watt. The battery will get drained very fast.

    Hmm. neat little example of the power of electromagnetic fields created by inductors.A minor warning to anyone: This will practically short-circuit batteries. Don't use use this non-stop as the battery will heat up and don't use lithium(-ion) batteries, they can be rather explosive...

  • DPScope SE - the simplest real oscilloscope/logic analyzer on the planet

    Looks well designed, Good reasoning, proper care on the oscilloscope input to be compatible with scopes.But that doesn't change that this is more of a Assembly instruction manual of a kit then a instructable. without the source code and a "how to program" it is pretty much useless to the people that come to this site to be able to build their own. You can showcase you kit, but people would need to able to build their own without having to buy it.
