Batery powered DIY CNC phono stage
- Thread starter sachu888
- Start date
Good initiative Sachin. The person whom I'm working with on my project keeps buying stuff from digikey. So, let us work on a deadline. Even if numbers are less, we can work this out as he would order our components along with those of his. If you can get the gerber file of the PCB from Hypnotoad, I can organise to make very good quality PCBs even in small quantities. Let me know. Mods, to attract more eyeballs, could we have some space on the home screen like the group buy of speaker stands of Magma etc. If some amount needs to be paid to HFV, all those participating can share the expenses.

Thanks Capt.
Its a nice idea.I have already got file for PCB making and have a BOM for CNC.Please let me know about PCB's if they are good quality and cost effective.PM me your mail id I'll send you the PCB file.

Sachin

Count me in guys. I am looking for a simple DIY project to start learning basics and I need another Phono stage too. But friends, I need bit of support here as I do not know much about electronics 
. I can solder simple stuff, thats about it.

Only soldering is required for this project,no worries.

Hi, Sachin, sending you a PM.

Hey Santhosh, George knows someone who is a professional electronics guy. This must be a 15 minute job for him.

Re: Group buy update for CNC
I don't think mods have seen this thread. To attract more eyeballs, it would be prudent to put a ad link in the home page. Why don't you take up with them?
Just a suggestion. What do you feel?

Hi Rajeev,
All components are available with Digikey with less or similar cost.We have a BOM with Digikey part number.It would be cheaper if we buy all components from one company.
Regards,
Sachin
Yes, Otherwise shipping will be paid more times for least components. Other thing, if we get hold of premium caps for required value then it will be good. [No point in saying that ceramic caps change capacity wrt voltage difference they are facing. This colors the audio signal. Hence start using polysterene etc. This is no good reason to use polysterene caps]

This is my thought which could reduce cost further shipping-wise/quality-wise. Anyway I am open for what everybody decides. Please give a thought on this.
