| Dear colleagues, I am new on this forum and happy to share something I made. After my first e-cig buy (it was usual 510 kit, May 2010) I wanted to be more independent from batteries and quickly made something like very simple passthru.
I was an analog smoker previously, so found an old table-top lighter, disassembled it and soldered electronic switch with power Darlington transistor inside. Why not MOSFET? Because I planned to supply this mod by 5V power supply from... mmm... something like USB hub or similar device. But at this time I used standard 510 atomizers and needed voltage about 3.5 volts. So Darlington transistor should be right: voltage drop was about 1.5V, and I got output approx. 3.3-3.5V.
That time I even did not have a connector for atomizers, so made it from a metallic pen, the thread was OK.
What I got finally:

| Later on I removed the lid, it was nice, effective looking, but sometimes inconvenient. The second image shows the power supply without the lid.

| In about a month I found the old charger for a Canon camera. Camera itself was lost or broken, I don't remember, but charger was in a good condition. I decided to make a spare charger which could be used separately being on a table.
I made the simple stick, imitating a standard Canon accumulator. The problem is that this charger is intellectual enough and does not work without thermistor inside accumulator. The charger was cheated by soldering a 10 K resistor. Everything is obvious on the pictures. I especially made the lower cover of the "accumulator" transparent to show wiring inside.
This charger still works

approach.
My kind of engineering

| Here is my button protection for eGo batteries. Does not increase battery diameter, reliable and replaceable. Made from stainless steel.

| Now we approach to more interesting thing. After raidy published his Genesis (Genisis) idea, I made my own prototype. Made from 2 polycarbonate (I guess) filters. Aluminium plate for heater. No lathe, only dremel, saw, files, drill, epoxy and soldering.
Finally I got this awkward monster. And it worked

question...have you seen the stainless steel mesh ever disintegrate over time in the atty?

| berger, thanks. All these things are in the past, I just want to share some interesting constructions
About mesh: sometimes I have seen something like the mesh was "cut" by the wire. It was when I just began my experiments with Genesis. Now I don't see it. I suspect either too tight heater wire or overheating of some heater parts. Using 400mesh from themeshcompany.com - satin mesh, excellent for me.
About contacts in this atomizer. One of the best construction - a thin tube with thread inside and a small screws. Sometimes modders have difficulties to find suitable tubes. My suggestion - use aluminium rivets for rivet gun (don't know english word for this tool). I used them approx. 3mm diameter. Just remove central steel rod usind a hammer (just tap), make appropriate thread inside and you have the nice tube. Aluminium is not hard enough, but if you use long screws and don't force them, no problem. When you make thread inside the tube, it's useful to gripe it in a drill - no damage and reliable fixation.
Here are these rivets: 1 intact, and 2 with removed rod and already prepared to installation (filed cup).

| When I tried to connect my prototype to a standard eGo battery instead of Provari, eGo battery declared short circuit and switched off. I did not know, why: Fluke and Provari show normal resistance, on Provari everything worked fine. But both of my eGo accumulators stubbornly declared short.
I remembered that output on eGo - pulse voltage with high enough frequency and suspected that stainless mesh with heating wire spiral around can work as a transformer with shorted secondary coil (the mesh could short wires inside the wick). To check out I soldered a ceramic capacitor in parallel to heater and accumulators worked like a charm.
The most interesting thing, that I observed these false shorts only on batteries purchased approx. in June 2010. Later I tried younger batteries - no shorts!
Here is my experimental intermediate adapter with soldered capacitor. On later constructions I soldered small capacitors inside of atomizers.

| Continue. After a few experiments I made my first Genesis for everyday use. It made with purpose to fit Provari with dimensions and appearance. Required some simple lathe work. Stainless steel and aluminium.
Here it is.

Sweet.

| Found out the very interesting board on eBay - small balancer for 2 Li-ion batteries in series. This is not a full charger, but with this board much more easier to develop 2-batteries mods, if you want to charge them without removing from the body. Needs an external power supply with current limit (charging current) and constant voltage 8.4VDC, but this is very easy to make. Actually this board is a balancer with standard overcharge/undercharge protection. Small enough. http://www.ebay.com/itm/Protection-B...item3cc054be59

| 8.4V is the voltage needed for 2 accumulators in series. 1 accumulator 4.2V, 2 - 8.4V. And the board just balancing this. But you also have to limit charging current by your external charger. It is easy to make, say, using this: http://www.ebay.com/itm/5-35V-LM2596...item3cbe0d06e2 This device is able to adjust everything needed for reliable charge.
Without balancer you can overcharge one battery and it will be damaged.
Well, another find. Every real modder knows, how difficult sometimes to find nicely looking and functional body. A modder from Russia (not me) found out very interesting idea: use portable ashtrays! They exist in different hypostasis, even stainless. The more acceptable for our purpose is this form factor: http://www.ebay.com/itm/Zippo-Pocket...item35b7cd22f1
This is just an example, there are a lot of similar things everywhere with different sizes. You can try to search something special for yourself with keywords "pocket ashtray" or "portable ashtray".
I like the idea.

Or does the balancer handle this?

| berger, the balancer only keeps voltage on both accumulators equal. Charging current, maximal charging voltage and 1/10 of charging current, when accumulators counted as fully charged handled by external charger.
Actually you have a charger for virtual accumulator with doubled voltage, simple bipolar charger. And the balancing board inside your mod supports this virtual accumulator in normal condition
Sorry for my English, I feel stupid 
P.S. But this board is not only balancer, it's also standard protection. I.e. you can use powerfus unprotected batteries without a risk to damage them by undercharge. | |
