What is UltraAddons? It is set of different useful stuff for IC2.
Have you ever tried to use IC2 dynamite? To use it effectively you can mine 2 blocks, put it inside and explode.
But what if you had a device that does it for you? That's for BlastDrill is made!
Blast Drill
You can see the drill itself, 3 different types of dynamite with electric fuse and dynamite box
To create explosion, point your drill to front central block of future explosion and hold use button (like shooting a bow).
By using IC2 mode switch key (default M) and right click when holding BlastDrill you specify which dynamite it should use.
The drill will use dynamite from inventory and from DynamiteBox (no priority given, first found used).
Dynamite box can hold 1024 of each dynamite.
3 types of dynamite: light, normal and heavy
Light dynamite mines 3x3x1 (9 blocks), Normal dynamite mines 3x3x3 (27 blocks),
Heavy dynamite mines just like normal one, but it can mine hard blocks (like obsidian or GregTech granite).
Recipes
And that is all content for now, but I have some ideas for future updates.
Planned content
Glowing gas and gas sprayer (or something like this).
It will be used to illuminate area without torches (basically by creating invisible light source blocks).
Also BlastDrill can have an upgrade which will spray this gas automatically after explosion.
Usage in modpacks and GregTech 5 (unofficial) support
You can use it in any modpack without special permissions. Don't ask me about it.
Also if you really want to port it to new Minecraft version earlier than I do, just do it.
What about GregTech? I have a nice ModTweaker script for you: get it from pastebin
GregTech recipes with this script installed
