Tell me more!<br>
<br>
We've been thinking about doing a pick and place along the same lines as the CNC kits you can get from places like Oozenest.<br>
<br>
<br>
I'm not sure what DIY means for me tbh. I'm enjoying applying a lot of the hackerspace type stuff to SDIY and finding you can do a lot of personal manufacturing without paying tens of thousands of pounds. We've come a very long way in the past few years in terms of doing the types of things at home, which R&D teams struggled to do 10 years ago.<br>
<br>
Panels for example... I can order aluminum sheet online, take it round to my silkscreen pal, who prints a design made in Illustrator (the subscription version). These are then cut on a CNC made from a £700 kit. It's a manufacturing process that costs about £1k end to end. It's been a struggle to get the process down, but I guess the challenge is solving those little problems.<br>
<br>
Hmm, maybe that's what DIY is for me: solving the "next" problem without the resources available to big businesses :)<br>
<br>
Kind regards<br>

One of the things that's important to me now is trying to design projects that will inspire people to try something a bit further on from what they might have otherwise tried. I've been using PICs to try and reduce the number of components in classic circuits and make them easier to manage. Basically, I'm trying to design the stuff that I would have wished for when I was starting out.<br>

> Personally, I don't have access to anything like your lab resources, Jason, and I doubt that people I'm designing for do either, so through-hole is pretty much essential. I try to avoid needing an oscilloscope to trim a circuit, since although I've got one, many people don't. The scope is to help the *designer*, not the *builder*. I assume only that they can solder reasonably well (although I design boards with *far* wider tolerances than you're doing) and that they have a multimeter. I've started doing stomp box stuff recently, and the people who build that are…well, they're *guitarists*! They know which end of the soldering iron to hold, mostly. I'm joking, but the point is serious - some of the people involved in music DIY aren't technical people at all. And this is a good thing. Perhaps some of them will become interested and take it further. After all, I did.<br>
