DIY vactrols
Scored a bucket of these from a long defunct audio company. It is pretty good experimenting with different coloured LEDs and different LDRs. Some to look for are GL5549, which have 10M-15M off resistance, and GL5516, which is about 5M.
Off resistance is important when using vactrols in VCAs and panners...which is something I have been doing a lot of lately. Of course the speed in getting there is important too, but that is more critical in LPGs.
Anyway just putting some pictures up, in the hopes that
1. someone knows where to buy these (please comment)
2. someone with a 3d printer decides to make some (again please comment)
update - flab on muffs has developed a great looking 3d printer design

Super Sloth gives it to a MN Telharmonium
This is nice, thanks to scatterfold for posting it.
JonDent's NLC index
Jono has put together quite a few pages exploring NLC 4U panels and build diaries of Eurorack modules. Well worth a few hours, his vids tend to be nicer than mine too.

BOOLs panels & PCBs
These are nice. The inputs can be any signal crossing 1V. The logic outputs give 5V gates that are all related to each other as made up of different input combinations. The S&H input can be a
trigger, gate or CV. The stepped and slewed outputs an be very similar to what comes out of
the Sauce of Unce or Buchla 265 SOU. The ICs are all thru-hole,
resistors can be 1206 or 0805 smd. Pretty easy build, has 4 LEDs for
blinkenlights.
Using different logic chips gives you some pretty different behaviour so it is worth having more than one of these. The XOR/XNOR chips cn be used as crude ring modulators at audio frequencies.
This is a great module for just patching in any spare outputs from LFOs, sequencers, ADSRs, etc and generating a whole bunch of gates and CVs that are sync'd with everything else going on in your patch.
PCBs - US$18
panels - US$20
airmail - US$5 per order

BOOLs
This module is like a hybrid between the NLC quad logic module and the Sauce of Unce. There are 4 inputs driving chained logic gates (you can choose what logic you want - OR, NOR, AND, NAND, XOR or XNOR by the chip installed). There are 4 gate outputs giving the boolean logic result of the signals on inputs 1&2, 2&3, 3&4 and 4&1. A resistor ladder network gives the stepped output based on what these 4 outputs are doing. From this a S&H circuit with a slew processor gives a smooth output. PCBs available now - US$18. Panels will be available in mid-July for US$20
