Remote detonation device for airsoft – REMDE

If you were reading my blog you probably know that I play airsoft for several years.
Here the sites that we play in don’t change often and in most places airsoft grenades can be used.

In Lithuania, airsoft grenades are essentially firecrackers with up to 1g of powder placed in a small container and filled with BBs, dry peas or anything that is kinda round and represents shrapnel. Very simple, effective and you don’t have to pick it up after using.

So, in that time I noticed that a device that ignites a grenade when I want to at a set location would be very useful when taking back positions from enemy whenever they would barricade themselves in and I dubbed thee – REMDE. For open fields, I’ve come up with a solution that I wrote about here to fling grenades much farther than I could by hands.

The device functions very simply – the bare minimum is made up of two devices – the transmitter and the receiver.
Whenever I go into a nice position that I know enemy is going to sit there when they take it, I place the receiver down somewhere, attach an e-match (the very same used for firework shows) to it and attach the grenade to the e-match.

Now when I need to, with one button, I can check it’s status if I have multiple receivers and I forget if I had used it. With another button I can send a command to ignite the e-match.

Delphi Logo

Howdy y’all. A friend asked to make an application as a plugin for the radio station he has. Application to update the “Now playing” list with each new song playing on the radio. For this it has to check a text file, read the name of the song, and if it isn’t the same as before – send it to the server.
Simple concept for a simple application.

Sokol-304

sokol-304

Hello. This time I’m gonna write about another antique thing that I had found in the basement when I was moving elsewhere to live. That was ~3 years ago and the thing is an very old Russian radio “Sokol-304”. The radio itself is ~25 years old probably (older then me :O) and the best part is – it works just as great. Of course, the contacts were rusty so I had to replace them but all you need for it to work is batteries.
