Hi,
My friend drives an electric Smart Car to her job, which uses about 50% of the car’s charge per day. This was great when we were renting a house and could plug in the standard Level 1 120v AC charger, but now we’re being displaced to an apartment and won’t have access to a power outlet near the parking space or access to any charging…En afficher davantage

So the question I cant seem to figure out. My options:

the machine just arrived in our workshop in 4 months. it is built in 2000, but it is in a new-like condition, almost. the laser power goes up just to ~3860 W, and we don’t know why, yet.

Hi,

Mind that I’m only looking at EFT numbers currently, but suppose we take dual beams vs 125mm. On a 1:1 basis, they come out with worse DPS, and that’d be fine, but they also seem to come out with worse alpha and worse tracking on top of that (although anyone serious about using long range weapons should have angular mitigation tools at their…En afficher davantage

Hi,

I can see a spark, but can’t get it to ignite. I have tried using hairspray and Lysol, and have tried different amounts of both.

I also tried wiping off the screws for a better spark (which actually seemed to help, but still no ignition.)
Please help.

Hi,

I’ve been stripping old laptop batteries to reclaim cells and testing them for capacity.

I boost charged a number of « dead » cells up to the point where a lithium ion charger would « see » them and charge them properly.

Afterwards I sorted them out, dumping some that were beyond hope, kept the good ones and also put to one side a bunch of low…En afficher davantage

Hi,

I have been target shooting for a while now, and want to get into hunting with blowguns. As of now, I only shoot a 5′ 50cal blowgun, and I do not think that it is suitable for hunting. Therefore, I am looking to build one in a larger calibre- a .75cal.

Would this work well to take small game such as rabbits and squirrels?
