The last of the piggies.

With the year coming to its conclusion, it seems an amusing coincidence that the last Piggy now finally got sold. 🙂 The Piggy was our first synth, a simple and affordable shield that turns your Arduino into an MIDI-driven analog bass synth.

We might do another batch.. The filter would need to be revised (dual gang potentiometers are getting rare!), maybe even changed into the Sawbench VCF.. But we need to know if there is enough demand. The usual address applies tastychipselectronics@gmail.com. Either this or post on Tasty Chips on Facebook or Tasty Chips Forum.

Looking at what’s in store for 2016:

– The ST4. This beast of a synth/tracker has got its own page here: ST4 info page. As said, the Kickstarter will take place in january!

– The Sawbench mod board: modify the Sawbench to accept external CV for VCF and use and external input signal (If there is enough interest).

– Sawbench firmware update 1.2: including synced LFO, tighter envelopes and possibly exponential envelopes too (If there is enough interest).

– A big analog Eurorack sequencer with 2×16 steps and loaded with features.

– Sawbench VCF/VCA Eurorack module.

– The next polyphonic beast. This will be less channel-driven than the ST4, but will have more channels (yes, that does make sense 😉 ). The focus will be on polyphonic harmonic sculpting..

– The MIDI sequencer (“tracker”) taken from the ST4 released stand-alone, with more controls geared towards pure sequencing.

Kickstarter finally over. Sawbench now in the webshop!

The last sawbenches have now shipped. This also includes the custom edition (with better components and custom artwork), as shown in the picture!

And.. The Sawbench is now finally available from the shop: Sawbench product link !!

The near future: we’ll keep selling the Sawbench (as long as our stocks last) and naturally we’ll support all of the buyers and Kickstarter backers. In the next days the kit products will also become available in our webshop. We’ll also put the firmware sources online and a firmware update might also be coming up soon.

Stay tuned!

 

Sawbench update: 120x PCB’s, casing, planning

The electronics

This week the 100 analog and 100 digital sawbench PCB’s finally arrived. We already had 20 before and these are now fully soldered and tested. The PCB’s seem fine: the silkscreens are now DIY-proof (all values are printed).

There’s one set back: the snap-in holes of the potentiometers aren’t big enough. In the past it’s been hit or miss. Either they are just right or too small. The supplier seems unable to tell us what’s up with that. Our guess is, it’s not a very accurate process. Not as critical as the rest of the PCB. The holes in the EAGLE drawings are small too. Seems like a lucky accident that they sometimes end up being bigger.. Oh well, next time we’ll change the diameters. For now, it’s manually re-drilling 1200 holes (!!!). This is a day of work, so nothing to worry about, except a sore thumb. 😉

100 analog and 100 digital boards.. arrived yesterday.

The casing

The casing design will be finalized today. And we can say it looks fantastic! An early version:

The graphics will be inverse. The background will be aluminium and the font and drawings in blue. The best news is that the colour will be integrated into the aluminium skin, making it scratch-proof and solvent-proof!

Honestly, we cannot wait to get our hands on these casings, but it will have to wait for a bit. Read on..

The planning

There have been some questions about the delivery schedule..

First of all, Kickstarter informs us of a 14 day period to collect all the pledges. This would (ideally) mean we’ll have the money by April 16th.. and can then start paying for casing fabrication.

The way it looks now the bare bones kits will be able to ship this month (April). We have enough PCB’s and a small batch of potentiometers should arrive in a few days.

Casing production (of 200 units) will take 4 weeks in total, and can only start when the Kickstarter money is in: it’s the most expensive part of the product.. We’re trying to get the first 100 casings before the end of the month, but we don’t know yet if this is possible. We’ll update this post when we know more.. Worst case estimate is that we can start assembling the full units from May 14th onwards.

  • April 15th: barebones kits start shipping
  • April 15th: first batch of potentiometers should arrive
  • April 16th: Kickstarter money should be transferred
  • April 16th: start of casing production
  • April 30th: (POSSIBLY) first casings should be available
  • April 30th: (POSSIBLY) the first 10 cased units may be shipped out!
  • May 8th: final batch of potentiometer knobs should arrive
  • May 14th: casing production done
  • May 19th: final batch of potentiometers should arrive
  • May 20th: shipping of kit+casing and full unit should commence
