MiniTiouner Hardware version 2
Re: MiniTiouner Hardware version 2
It's easy to order from DigiKey. If you follow the instructions on this Portsdown page you can upload the spreadsheet and order the parts without retyping the part numbers.
https://wiki.batc.tv/Filter_Modulator_build (look for the Parts List paragraph)
Enter zero quantity for the non-DigiKey parts and they will be ignored.
Increase the quantity of item BC2665CT-ND to 10, if you don't, they will offer you the option to do so, which might be a bit confusing the first time through the process.
If you select 'Customer Reference' for the spreadsheet column 'Designator' the bags will be marked with the project's parts numbers.

Digikey charge postage on the Minitiouner parts, however you can avoid the postal charge if you add the recommended Hammond enclosure to your list.It's easy to order from DigiKey.

Re: MiniTiouner Hardware version 2
I got some of the parts from Farnell for the last build so this is not a complete list. I already had resistors, headers and some of the capacitors etc. Hope its useful. Note you can substitute parts fairly widely, e.g. use a 470uF for the input capacitor rather than a 680uF as they come in packs of 5. Just make sure the 22uF caps are low ESR.

Thanks Mike.
Re: MiniTiouner Hardware version 2
Referring to the voltages that should be found on L1= 3.3v, L2=1.1v and L3=3.3v there is a tolerable range specified for L2 only of 1.05-1.25v . I would be most grateful if someone could please tell me what the tolerances are for L1 and L3. Mine readings are L1=3.275v and L3- 3.291v and I've no idea whether these are acceptable or not.

Re: MiniTiouner Hardware version 2
Someone asked about acceptable voltage ranges from the linear regulators - the formal spec for the NIM is 10% but that's a lot. Normally I would expect the regulator outputs be well within 5% of their nominal 3.3v or 1.1V values. If you do measure strange voltages its possible the regulators are oscillating. That would be caused for example by not using low ESR capacitors.

Re: MiniTiouner Hardware version 2
ust ordered the PCB and tuner too and was wondering what DC-DC converter would fit on the PCB.G3UKV wrote:Starting to sort parts out for the Vers 2 PCB. Looking on eBay there are various DC-DC converters, but none look like the photos.
Can anyone advise an eBay item number for it, so that it will definitely fit the PCB please ?
The ebay links in the forum are no longer showing on ebay
Can someone please advise
thanks

If you search for "MP1584" in eBay, the top listings are all the right type. For example: http://www.ebay.co.uk/itm/UK-MP1584-3A- ... SwNSxU1lcu

Notes on building the BATC v2 Minitiouner.pdf
I can't see that anyone else has picked this up so I will mention that: the schematic (Minitiouner v2.1 Rev.1) in the excellent https://wiki.batc.tv/File:Notes_on_buil ... iouner.pdf does not show the 5.6v Zener diode D3 across the output of the DC-DC Converter, prior to J2. (As a former PCB design Engineer I'm used to spotting these differences).
