More money for modding

Yep But I don't earn exactly from him, I get salary. We are just friendly and never cheat each other. They are great guys. I choose them to support because they are very comfortable to deal.

I dreaming to make something like passthru from this "grenade" purchased in a chinese shop. Should be impressive on a table

Slimest your one sick man. I like it.

Thanks gwp. We are all a little sick here

I sure you realize that 'device' is simply a computer generated animation.

tek

Yes, and i also saw the completed version. So...

quasimod

I did, but these look real

Unfortunately, he has no grenade mod, so I am finished with him.

Very nice work Oleg.

I want one of these.... sweet Will be very cool if you can make something from it.

slimest

Thank you colleagues. Actually I don't do something original, but try to make it thoroughly and always develop systems which should be easily reproduced by someone else.
Now I will show my latest system - power supply in stick form factor with all included: powerful enough 18650 battery, charger, allowing to charge the battery from a standard USB, powerful varivolt with buck-boost options. The purpose was to make very compact and lightweight cigarette with minimal metallic parts. I frequently pass detectors of metall on my work, so this cigarette should not be detected. Maybe some of you already seen this system on ECF, but without it this topic is incomplete
I choose self made body from fiberglass - glassfiber tissue with epoxy inside. It's very easy to make. The body consists of fiberglass ovale tube and two lids - bottom and upper. Upper lid made together with carrier board, bottom lid is separate and fixed by 2 screws to the carrier board, so everything tightly gathers without gaps.
Every lid made from 2 parts - inner and outer, decorative. You can make them from a plastic using just a saw and a flat file. Two parts made separately then the sandwich glued together. After gluing the lid I finally processed the decorative part. The tube part of the body covered by thin natural leather taken from old passport cover.
On pictures from left to right shown: main part of the body covered by leather; upper lid with holes for atomizer and button together with carrier board; bottom lid.
Outer dimensions of the whole body are 80x38x23 mm.

This is the best one yet!

I'd sure like to know how you made the fiberglass housing and the stick carrier??

slimest

Thanks Shekinahsgroom. To make the fiberglass housing I put together 18650 accumulator and long eGo accumulator. If you need another dimensions, use something suitable. Very impornant to put a plastic plate between them to achieve appropriate dimensions and also to make easier removing everything after epoxy hardens. Then the whole sandwich covered by 2-3 layers of usual plastic packet used for food etc. No wrinkles. Very important to test this plastic first if it can be easily detached from hardened epoxy. Then mix epoxy compound, cut fiberglass tissue (thinner tissue - better) and wind gradually the tissue impregnating it by compound. Avoid too much compound, it should be only inside the tissue layer. Remove excess. That's it. The fiberglass wall thikness about 0.7 - 1 mm is OK. After hardening (2-3 days in normal temperature) you first remove by pliers the plastic plate between accumulators, then everything easily removed. Now you just finish edges and surface.
If you never worked with fiberglass, try first on something useless. Don't use 5-min epoxy, it hardens too fast. Very good practice is to use a small plastic packets as gloves. To remove ready housing you can use scissors to cut uneven edges. Let extra edges of protective plastic to be long enough to avoid pollution of accumulators by epoxy.
In common making fiberglass is easy enough, just don'allow excess compound. Even if you have some parts of housing without compound, it's not difficult to putty them later.

The carrier made from an old electronic board and glued, nothing special. You can use any available plastic.

This would make a very hot item here, slim, if everything could be packaged into a "DIY kit" form.

Modders would LOVE this!!

I give the idea of the housing to everyone who wants to sell these kits. I don't

Let's go. For voltage adjustment I used canadian eGo booster. It has great parameters and compact enough. If I had opportunity to buy a board from, say, TI, I would, but in Moscow it's very hard to get, and when I tried to order something from Digikey, they asked shipping price about 40 dollars, so I gave up.
Well, the canadian booster is good enough. Another electronic part was charger. I bought 2 USB boards here: http://www.ebay.com/itm/2Pcs-USB-5V-...item2c6234eead
These boards happened to be very good quality and their charging parameters are good. After cutting some parts of the board by Dremel I got charger approx 14mm diameter and about 3mm high. Next electronic part is button. I soldered it by myself on a small board. It has usual schematic.
On the pictures from left to right: USB charger I purchased; the same board after I cut some parts; my electronic button.

The booster fixed on the carrier board using simple pin made from a steel wire about 0.8mm diameter. First I drilled two holes in the booster body in the connector area so that the pin does not interfere with connector (it goes aside) and can be easily inserted and removed. Then the booster was positioned on the carrier and fixed temporarily by rubber o-ring so that it was properly aligned and the adjustment knob was absolutely perpendicilar to the plate. Now I used acrylic compound to fix the pin. Of course previously I protected booster surface by teflon plumber tape. Very important: before compound absolutely hardened it's necessary to rotate the pin. It allows to remove it after compound fully hardens.
That's it. Now cut the pin to the needed length, insert it, and the booster reliably fixed against rotation and any movements, it only can a little shake. And this is good because no force to connector, only to upper lid. If you need to remove booster, just remove the pin, and the device in your hand.

P.S. You can see the charger board already mounted to the plate by the same acrylic compound. The gold coloured connector on the back will be screwed to the booster input connector later.

After the plate preparing we should mount all the electronic parts and solder all wiring according to schematic.

Now it's time to mount previously fixed in the plastic microUSB connector for charge. The connector frequently interferes with cable, so it has to be reliably fixed. I used 2 small screws to mount the connector between the booster and charger board.

Seems that I'm talking to myself... Colleagues, do you need these ins and outs? I am new on the forum, so maybe I talking about obvious things? If so, just say. No offence at all.

quasimod

You're not talking to yourself. I am interested, and I am reading, but I am not very technical so I have little to say. The name "quasimod" has nothing to do with "modding", I drive a truck for a living. I am wondering how you will complete the electrical connection to the mod.

Also, there is no way to guess when this forum will get "busy" or be dead.

I think it is awesome, and it may have me working on a similar idea in the near future..

slimest

Ha-ha! My neighbour does the same. And he is vaping now. Once he saw my e-cigarette, tried, coughed the first time, but then purchased eGo and now he is a vaper
Once he suggested to me: try to drive my truck (veeery long!) backward.. I tried... It folded instantly

Thank you, colleagues. For me it's not so easy to write big "novells" in English. I just thought - if this is obvious and does not have sense, why I spend my and your time...

berger

I appreciate your efforts..it just that some of it is over my head..

slimest

Well, continue. After making the main things I lost patience and assembled everything without housing just to try, using a rubber o-ring instead of housing. It was great!!! :lol:
I shure connected my favorite atomizer and tried to vape (no patience at all!). Great! Incredible!!!
On the first picture you can see how all parts set on the carrier. The second picture shows charge test.
You see: no space for spring contacts, so accumulator connected via soldered wires. Accumulator - AW IMR 18650, shortest in its family. It allowed to achieve smallest dimensions of the power supply.

Then I did very boring thing - holes in the housing. Needed holes: for adjustment knob, for USB connector, for charge indicator (should be closed by a transparent material). Also I glued a.. don't know what is English for it... to hang the cigarette to my neck.
Finally I got:
