A long overdue update

Hi. Long time, no see.

I’ve been dreading this moment. Opening up my inbox and seeing all the comments and emails I’ve been missing. I haven’t spent a minute on this site for well over a year, maybe two, and I’m not sure I will ever get the time to sift through and reply to all of you, of which I am sorry.

You’ve heard the story many times before, and it’s not particularly exciting. I’ve been struggling with personal issues and went through a really rough time, which is not to say everything is now going great, but I am slowly trying to pick things up again. Maybe not exactly where I left them, but we’ll see.

I know a few of you ordered pre-programmed tap-tempo chips, and I hope I managed to send them all out.

I haven’t been keeping up on the features and updates on my vero/stripboard app. I have some ideas and a lot of bugs; if I do find the time I will get to that.

I haven’t stopped doing projects, it’s one of the things that has kept me sane, but I haven’t felt like doing all the work that goes into sharing it. Hopefully that will change a bit.

Tap-tempo v3

I’ve been working on (still am to be honest) a new version of the tap-tempo LFO. There’s a few new features, like:

  • Rotary encoder input toggling between and selecting multiplier, waveform and tempo adjustments.
  • The just mentioned speed adjustment – You can now micro-adjust a given tempo rather than having to tap in a new one.
  • New “random” waveform – I hope to get some fun out of this one myself.
  • Many new multipliers (Base tempo is 4/4):
    • Whole notes
    • Dotted half notes (new)
    • Half notes
    • Dotted quarter notes (new)
    • Quarter notes (1:1)
    • Dotted eighth notes (new)
    • Eighth notes
    • Dotted sixteenth notes (new)
    • Triplet notes (new)
    • Sixteenth notes
  • LED indicators for both base tempo and actual tempo (current multiplier).

Source code is now available for free on github under GPLv3.

It’s not done yet, but getting there. I plan on also bringing the attiny85 up to the same standard (minus a few features). As earlier, I’ll also try to keep a few pre-programmed chips available for those who prefer not to get into the programming side of things.

Keep watching this space for more info soon.

Status update

You haven’t heard much from me lately, and I’ve been busy with a disproportionate amount of real-life stuff, but there are things to come yet.

I started working for a new company a few months ago. While this leaves me with less free time I can use for electronics and noodling, I’m fortunate enough to now be working professionally with things related to electronics, circuits, audio signal processing and microphones! I’m hoping this will have a positive effect on my DIY tinkering as well smile emoticon

I’m actively working on the next update for my pet project, the StripboardCAD app. This time around I aim to improve workflow related to the parts list, entering of data/values etc., fueled by myself starting to use the tool actively and noticing a few short comings.

A few of my good musician friends have been trying out the “Workhorse” project I put together, and they’re so enthused about it that I’ve now built a few units for sale. That was a pain in the *behind*, and took much more time than I would have wanted, but hopefully it’ll come out well in the end. I even hear some plans about a demo video; a first for anything I’ve been involved with, and only (potentially) happening because I’m not doing it wink emoticon More to come on this soon (I hope).

I’m also revisiting the tap-tempo LFO stuff. While it has resulted in some very cool effects (I’m most happy with the tremolo), it has also disappointed on a few occasions (the phaser, to name one) due to overly noisy design etc. There’s two things to take away from this:
1) I need to learn more about proper grounding in digital effects, and how to lay stuff out on a vero/circuit board.
2) There are still things I would like the chip to do, like integrating a manual tempo adjust pot, a random wave form, and more options in the multiplier department (triplets etc).

And, of course, there are a number of other ideas I’m also playing with, that might result in something further down the road. We’ll see.

I’ll try my best to post more news before the year is over, but just in case:

Merry christmas and a happy new year! Thanks for your support in 2015!

Quick update on app progress

As quite a few of you know I spent most of my time last year working on a vero layout app for iPad. I was initially hoping to finish it up by Christmas, but  obviously I missed that mark. That’s the bad news.

The good news is I’m still working diligently getting it done (I guess that might actually be bad news for those of you hoping I’d have more layouts ready instead). I’ve got the famous 90% ready, and only missing the last 10% that always end up taking the most time.

Here’s a few screenshots so you can get an idea where I’m at right now.

ivero_app_1ivero_app_2ivero_app_3ivero_app_4ivero_app_5

As you can see I did a quick mock-up of the Korg SDD-3000 layout, and it looks quite nice. But you’ll also notice there are a few things missing still.

All the basic graphics work is done, with only minor tweaks remaining. It’s vector based, scrolls and zooms nicely, and looks great when exported to PDF. There’s the component picker on the left and the parts list on the right, and you basically just tap, draw and move stuff around as you wish.

There’s a basic menu for entering meta data, like layout title, author etc. and this info will of course end up on the exported layout along with the layout image and parts list.

As my goal for version 1 is to be able to replicate my own layouts the way I have them drawn now, I’ve left out things like pots, switches and wire. That’s not to say they won’t be included, but not in version 1 (or I’ll never finish this thing). What I’m going to have instead is an “off-board” menu where textual representation of these things can be entered (like my layouts today).

The export menu is also under construction still. I’m hoping to be able to generate both PDFs and PNGs, but may cut it short with just PDF to get started.

Also, not visible here, is a file manager back-end that needs to be in place before release. I have something very basic right now that needs to be replaced with something proper. iCloud-support may or may not make it for this version, but I’m sure to add it eventually since it’s a feature I want to use myself.

Plans now are to complete the missing parts and try to get this thing up on the App Store somehow. I think there’s a beta-program as well, but again, that’s another few developer documents/books I need to consume to have it all figured out. We’ll see, but in the event I’ll have a beta run I’ll be happy with all the help I can get.

And so I have a somewhat awkward question for all of you. Assuming I’ll get this thing out the door, I need to put a price tag on it. I’m not totally comfortable charging money for the things I provide here (I like giving stuff away), but then again I can certainly also use what funding I would get and put it back into future development and other related projects. I have probably spent several hundred hours on this so far (most of it being a lot of fun) and would of course like to see other people getting some use from this, but in the end I did build it for myself first and foremost. What do you people think? What would you be realistically willing to spend on an app like this? From asking around amongst friend I get everything from $1 to $100.

Anyway. Hope you all have a great 2015!

I’m still here!

In case you were wondering, I’m still around. So here’s a quick update on what’s going on.

First of all, if you haven’t yet heard, I’ve gotten myself involved in iOS development. Specifically, I’m working on an iPad app that can handle drawing vero layouts, just because that’s a tool I’ve been wanting for myself. It’s lots of fun and very time consuming, and it’s what I spend probably 90% of my free time doing these days. With a bit of luck I’m hoping to have the first version done before the end of the year.

Second, I’ve been tinkering with the tap-tempo stuff for a while now. And as far as the chips themselves go I’m really happy. Where I’m less than happy is with the implementation. Having built the clock box, a tremolo and a phaser now, I’m seeing/hearing clock noise on the audio path and it’s not going anywhere 🙁 Time to finally read up on analog/digital grounding, noise handling, layout considerations etc. Any suggestions on good books or places to start reading?

Finally, I haven’t given up on drawing layouts. And when/if I get the aforementioned software up and running I plan on a major overhaul of all the content here, as well as a lot of new layouts.

Stay in touch, and happy building!

Planning to move

Update (10.08.2014): Looks like it’s working correctly, and everything should now be running on the new host. Let me know if something isn’t quite working.

Hah! No stupid out-of-memory warnings when accessing the shopping cart 🙂

(more…)

New shop section

I know a few of you have been asking for pre-programmed tap-tempo controllers, and over the last week I’ve been working on realizing this. In the main menu above you’ll now find a link to a small store with a limited number of said chip.

Now, I anticipate some growing pains in the beginning, but hopefully nothing that can’t be easily overcome. I do want to limit this to begin with, though, so right now I only have a handful of controllers up. But after the initial break in of the store, and if there’s any demand, I’ll add more stock.

Something else I want to mention; I have very little experience shipping/mailing, so the options and pricing in this area is probably going to see some changes once I get a few letters going. I’ve tried to estimate the postage, envelope cost etc., but until I get it right I’ll try to reimburse whatever extra shipping you may have paid (did that make any sense?).

The store plugin and paypal seems to really want me to list everything in Kroner, and not Dollars, and I’m sorry about that. And I know there’s something wrong with the description text under the store item. Will see if I can do anything about that when time permits, but right now I need a bit of a break 😉

Let me know if this works or not, and what you think.

New about section

Some more site updates, about me this time. I’ve added a new section called “about” where I’ve written a little about myself. I also plan to add some contact info etc. as soon as I get around to it.

As part of the site update I moved the “step by step” guide to the FAQ section as a sub-category. It’s a bit outdated at this time, but I haven’t got the time or enthusiasm to redo it right now.
