The 3d Monopole Coil How To Build

[Tom C]

Barrie,

could you send me the link for the book you are talking about on Jaycar?

Guys I just thought I would mention another option for fabrication. This is traditional machining and injection molding, not 3d printing as your discussing.

At this site you download their CAD for free and design with it. They give you choices of materials and tolerances injection or mill etc. Within the software you can get price quotes easily and change material to compare.

Anyway I designed my 8 coil machine and had them fabricate it for me.

Here on my thread for the machine on the first page you can see some of the drawings that were produced and the parts. They did a very good job for me.

Thanks Tom,

I just checked Jaycar in the USA... the price is totally wrong! Who on earth would want to pay US$999 for a 300 page book??? Must have brought back gold leaf or something for that kinda dough! Here's your link, followed by ours, with the right price. If it doesn't display, it's the BM7122, just run a search, which works locally for UK, Canada, etc too.

Of course, a cheaper way to do this is to use the NP4260 from Jaycar & just build a mold & sand it / work it until you get what you need for A$11.50 per 100g.

I found it on amazon. the reviews are not incredible for the couple of people that bought it. there is another one not yet in print that I may get instead.

I can see four reviews there; they all seem very positive, unless you plan on using something other than A123D? I can understand anything in print using online video tutorials would feel dated after the normal revisions have been effected in the physical product. That's a pretty good price on Amazon! What are you getting instead?

[Tom C]

I was looking at this one http://www.amazon.com/CAD-Autodesk-1...D2CRCH05JCCXNK

but will wait for the reviews. I have a pretty good handle on 123D but there are some questions and techniques I just canot seem to figure out. some of the more precise ways of drawing and dimensioning.

Now that looks well worth it! Did you pre-order? Saves a bit more that way. Do you know when it's expected? I'll recommend it to Jaycar as a new product line.

I just ordered this: http://www.amazon.com/gp/product/B00...IN=B00OCG91IK/

It's the exact same one John is building all his projects on right now and it has a scanner and is apparently easy enough to use.

The reviews are about 3+ stars, but most of the bad reviews are for the scanner, but from what I've seen, most scanners aren't that great because it is still to much in its early stages.

Anyway, excited to get it and start printing some projects.

It also seems to be rated pretty good for beginners and is inexpensive for what it does.

Aaron,

you will enjoy the printer. the last update of the software that was pushed to the Davinci printer closed the door on the hAck that allowed you to use non davinci filament. so you should stock up on Davinci filament. John is printing in ABS its strong and not does not absorb moisture like PLA does. buy lots of purple glue
Tom C

[Aaron Murakami]

Is this the exact same purple glue or are there different varieties? http://www.amazon.com/gp/product/B00...SIN=B00143UIC2

I saw a bunch at John's that looked like this.

Also, isn't it a matter of time until there is a way to reset or fully replace those circuits in the cartridges?

[Tom C]

aaron,

yes that is the glue I use, you can make it a few layers thick and it lasts for a while, I think I did about 10 prints so far and have not added more glue. office depot has it in 30 piece boxes. so for the cartridge on the Davinci, the hack was fairly easy for the first iteration

here is one of the best threads I have read on hacking the Davinci: http://www.soliforum.com/topic/6279/...acking/page/3/

people are working hard to make it open source, its just a matter of time. However DaVinci is counting on filament sales to stay in business, so part of their core of operation is to continue to make it hack-proof. let us know how the scanner is working for you. I do not think JB has used his scanner much.

It looks like the coils are 1000ft = about 800 ohms # 42 wire and I may change this to adjust the current
