I want you to focus on HF information.
Evening.
Bit of an early posting this evening as I've got loads to be getting on with.
I've had one of those days today, you know the one where you wake up at 08:00am full of verve and you just cane everything you feel like doing?
Well, post shower and breakfast I decided to get stuck into the CrabbMixerPedalThingamjig.
Collect all the parts together ready for install.
The first thing to do is drill the enclosure. I like to use a stepped drill bit, for a number of reasons, the primary one being that I'm lazy.
Centre-punch, pilot drill and then final drill. Easy.
Nice and clean. Oh yeah, forgot about this,.. I was kindly gifted some AWESOME coffee. Unfortunately I'll need to drive to Audlem apparently to refill.
Once drilled I like to test fit. In all honesty this is really a confirmation that ALL THE PLANNING I did before is correct. Not just the outside layout, but inside too.
For this build I wanted to try a couple of new things: a seemingly long time ago I ordered some solid core wire out of curiosity so utilising this was one such thing. In order to use solid core though you need to be succinct with your wiring, gentle bends, only a couple of movements etc... Anyway. I installed this built so it needed to have off board wiring done, to approx length to minimise wastage.
All done, and a quick check (being lazy I zoomed into this photo) to see if any bridges occur.
Nice.
I learnt to solder on Vero/stripboard, I'm glad I did because almost everything else seems easy in comparison.
I also learnt my lesson with the Alembic/SRPP jacks - these don't need to switch and I wanted a tidy layout so I bridged them.
In all the studio-DIY gear I've built mounting has been a big consideration. I've learnt a couple of methods and I wanted to try this now. I deliberately laid the top-cover the way it is to leave room inside to all the pcb to be mounted using this method:
This circuit uses one of these BADBOYS:
For anyone not in a geeky-poor-joke-clique this is about a bog standard a dual-opamp as there is. As much as that is true, I quite like the 'sound' of the TL07x series. Try one in a Timmy style circuit. Go on.
So it all got installed, plugged in, and probably as a result of ALL MY PLANNING it worked first time.
It successfully allowed my bass and drum machine to co-exist quite happily (normally this would have caused massive grief because of impedance mismatches/sharing).
So. Gut-shot and money-shot. Pics or it didn't happen right?
Hopefully you can see the planning pay off with the neatness of wiring, I've left a battery sized gap if T.C. wants to add one. Hopefully it will serve well and be reliable. T.C. knows where I live.
Now in the interest of full disclosure, being transparent I believe is the current political buzz-word, I want to show this edited worst-case photo:
You can see the yellowing and 'lumping' of the gloss clear-coat. It was the first time I used that so I need to make sure I understand how to avoid it next time. In trying to describe it I think I used the phrase "looks like it's been dipped in a 20-a-day smokers lung...". Yum.
I need to foam roll again, and I need to clear out the store cupboard and tidy my room.
Its not all Rock 'n Roll you know.
