And I just got mine too. Impressed by it's relative good precision, should've gotten two.  :-+

Great news, thanks for the feedback. I tried to spec reasonable quality resistors. Although only 1% they should be pretty decent most of the time.

Hi All,

I thought I should post this here. Someone (Juergen Gruendmayer - thank you) made a 3D model for a simple snap-on enclosure for the unit and he very kindly made this available for download, he posted on my blog, I thought I would re-post here  He created a simple snap-on box for 3D-printing, you can download it at http://www.thingiverse.com/thing:114201 and have it printed using your favourite on-line 3D printing service.

Just another small suggestion - perhaps it's better to provide coloured jumper caps instead of the black ones? I reckon it might make it a bit more readable as everything else (except the silk screen) is black. I will more than likely get myself some of those and replace them :)

Good suggestion, I will see if I can source them. Thanks.

Hi All,

I just wanted to say thank you to everyone who bought one of the decade resistor boards.  More over, thank you for all the positive feedback and the kind words of encouragement for the project.  The outcome was totally unexpected! When I had some made I thought to myself, I will get 200 made, I am sure some people would find them useful, and 200 should last a couple of years.  Well I was very wrong, they instead lasted just 10 days - as of now I am down to just 10 boards and if current trends continue they will be gone by tomorrow.  I have had interest from a couple of on-line retailers too, I had no idea there would be that level of interest, I was thinking that the interest was just a spike but after the initial spike it has remained pretty constant so this morning I ordered another batch of boards which I should get in about four weeks time.

So again, thank you all so much, I really appreciate it.

Gerry

And with some improvement, you should be able to sell more and more.

It's a damn good board...

Thank you for your comments. I hope so, I ordered a whole bunch more now with some slight improvements too.

1. Added mounting holes
2. Adjusted solder mask so there is better electrical exposure for 4mm banana sockets (if fitted)
3. Added a place for soldering a two-pin header onto the board so you can push jumper wires in (push fit)

hould be nice, in the next manu

-banana instead of screw contact
-a "plus" version with gold pin and jumper (or a self made jumper whit some little little pcbs for better quality) should be a good idea
-more dissipation for low value
...  I suppose it would be feasible to make some without any pin headers and people could install their own options ...

Gerry, I have ordered two of your units to South Africa and looking forward to use them. My I take you up on your suggestion to supply my order without the headers installed on the PCB. I will install the headers myself when necessary. Please supply the postal tracking number so that I can track the parcel in South Africa as the local Post Office is sometimes a problem with reliability.

Best regards

Johann

Hi Johann,

Thank you for the order.  The batch I currently have are all fully assembled I am afraid so you would need to remove the pin headers.  Perhaps in the next batch I could have some made without the pin headers installed, I will have to ask the question to see if thats viable or not.

I will look at what postage options with tracking there are, I have been using the normal international air mail which seems fine, I will check the option when I ship yours.

Gerry

Depending on where and how you select ( po box or physical address) the SAPO is either slow or incredibly slow. they are on strike ( but you cannot really see any difference, though it might reduce the theft of mail internally) for a while now, and are on a go slow ( from snail to glacier speed AFAIK) but regular small parcel post does get through in 4-6 weeks from arrival in the SAPO system. I haven't had one thing go missing so far ( Touch Wood) so it really just is slow.

If JohannP has a PO Box then I suggest he uses it, as then it takes less time, but you generally get the customs form to pay duty. Please declare a true value, the customs guys ( I know a few by sight now and meet them regularly on weekends in shopping centres as we shop there) are going to query lowball values for the size parcel. Unfortunately you will have to have an invoice or a declaration on the customs, and if postage is included in the price then it will be included in duty, otherwise if the price has a separate postage line ( close in value to the stamp amount) then they might subtract it. In all cases they will charge Ad Valorum and then VAT on this tax.

Hi Davide,

Thank you for the order, I just sent you an e-mail with regards to lead time, my first batch stock is fully depleted and the next batch are well under way in the manufacturing process. I should have this shipped to you by the second or third week in August. If thats not OK, please let me know and I will refund you.

Thanks

Gerry
