Its pretty simple to add CV to a basic 40106 cct. I just breadboarded a very basic one with a 4007 acting as the current source, super easy if you don't need proper tuning, I don't, & you like the idea of an all CMOS VCO, I do... or you could use a transistor - weak!

I think the biggest issue modding the W.O.M is purely real-estate as Tom pointed out. I suppose a gun solderer could surface mount some right angle headers onto certain traces... but really by the time you do that you may as well grab some vero board & CMOS chips & start F'ing about rather than potentially scar the masterpiece of miniturisation that this PCB layout is.

(The Lunetta part of my brain does look at all those "wasted"* gates & wonder 'what if I just' - maybe a future Workshop orientated design could incorparate a "sandbox" area with various pins brought out to a part of the board, like the CGS Wave Multiplier PCB, would ruin the aesthetics tho)

*We all know real waste is adding features just to use up avaliable resources.

Any more kits going to be available in the future? I got paid today and went to grab one and they're gone d'oh!
cebec
Ordered mine, too!
Can't wait -- my first DIY project.
Thanks, Tom!

I've got around 20 further kits to complete -- hopefully they'll be available sometime in the next couple of weeks.

Cheers!

Tom,

I definitely want one of these. Will they appear in the shop here
http://www.bugbrand.co.uk/index.php?main_page=product_info&cPath=24&pr oducts_id=34

when ready? I checked that link after you first posted they were avail and it showed none avail. I assume they just sold out in a few short hours.

Ya, for myself I will put aside all thought about modding it.
I promise to only fuck up my own designs! hihi

Awesome! I'll keep an eye out! hyper

Hey, I got my kit today!!
Amazingly fast shipping time, less then a week.
Really looking forward to CAREFULLY building this.
Thanks Tom for your well run biz!
Uncopyrightable
Got mine too, and just finished building it... took about 4 hours, but I'm a noob and was taking care. Mr. Green

And yay, worked on first run. MY ASS IS BLEEDING

Edit: Is it just me, or was there a sense of irony to getting a card included that says "Built by hand in Bristol, England" for a DIY kit? razz razz

It's fucking 3AM and the thing fucking works!!!!!
Woooooohooooooo!
3 of the poli box caps didn't seem to match the numbers in the
manual, but I put in the 2 matching and the one solo in the left over spots!
Took me about 3 1/2 hour I think. I should sleep..............
But I can't stop messing around with this damn thing!
BugBrand
Wow, the speed of shipping has me surprised too - that's great news.

And - whoop - well done you both on completing the machines! 3-4 hours is probably about right time-wise -- I've been running the workshops at 4 hours, with people taking about 3 hours (probably a bit quicker building in a group as problems can be quickly addressed)

I hope your caps problem won't affect the pitch ranges - feel free to post pics or email me. -- I know that the cap labeling can be a bit confusing and it is hard to explain clearly in the documentation...

If anyone else has problems on the caps then do feel free to post and ask questions!

Strange - they should have showed up (I always double check).
Sorry about that.. I'll give a shout when I get the remaining kits made up.

Just got mine took a day and i think i got a bit carried away !




i have changed osc 1 pot with a Norps12 LDR and added a velleman cricket board to flash the led and as a sound source (which only sounds when the led flashes) unfortunatly i have Blown the speaker as the signal from the cricket kit was too high d'oh! DOH oh well
BugBrand
Wow - amazing!
What does it say next to Bug? Is it Bug(o)la ??!!

Hey, for the speaker - just drop me a mail and I'll pop a fresh one in the post tomorrow. Seems strange that it should blow, but I guess you never know.

Cheers for the wonderful picture!
bar|none
Haha, awesome mod!

I love the thinga-ma-kit LEDacle.
matt the modulator
Hi tom cheers for the replacment offer ile email you with my details.i think its because the velleman kit i used is designed power a piezo buzzer. i conected the LED to the out put and to +9v and the output also goes to C13 (the mixer input on the WOM) ile have to look at that before replacing the speaker. I called it a BUG - Lab as the led stick (LEDackle) is inspired by the Bleep Labs thingamakit. I added a conection pen thing form a stylophone which is connected to one of the drive pads

The hands are amputated from a Buzz Lightyear which is currently getting a Thingama-makeover gunner be noisy light flashing fun when iam finished Mr. Green

here's a over head picture:
BugBrand
I got asked about replacing pots - mainly relevant if you're wanting to mount the WOM into a new case and use nicer knobs...

So! The dials with the kit are linear types (you can't get 'em in log)

Osc-pitch dials (1-3)
- these are spec'd at 100k, but for the bigger Weevils I tend to use 500k (linear) or even 1M -- the larger the pot value, the lower things go.

Osc Levels (1-3)
- these are 100k minidials but if replacing them I'd recommend using LOG type pots (again, 100k)

Drive - you could try a 100k LOG

Tone - 10k linear

Output - 100k log

Starve - this specs a 100k pot but you could experiment with a higher value (eg. 500k) - linear type.

Have fun!

yay! got my kit this morning- unfortunately i have no idea when i might get around to building it, way too much stuff going on in the next few days. hopefully i can set aside some time and get it put together sunday evening.
Soy Sos
Beautiful, inspiring little piece of kit. Used here as a Sample and Hold
and sound source with the mighty ARP 2600!

Hey - I know that it's incredibly wimpy, but I just have to ask - how much would someone (anyone?) charge to put one of these together for me?
bar|none
Just buy a boardweevil since it basically a preassembled one and has even more features I think.
droolmaster0
Oh, really? Well, mine just arrived yesterday, so I have that taken care of if that's the case.
eyehue
the chips look different on the WOM than on the board weevil. one is only 8 pin and i don't think it's another opamp. is it a 555? can Tom discuss the differences between the WOM and the board weevil? i have a postcard and board and may very well need a WOM if there are indeed significant differences.
eyehue
yea, what i said above.
DGTom
Its a LM386 as well as the 358, which from the datasheet is the poweramp for the speaker.

I won't know what chips are on the Weevill till it gets here grin but I think its 40106, 4077 & a LM324 opamp.... I think, & the 386 for the speaker again, I'm prob only half right tho.
Henfield
Any idea when these will be available again? The website says that is sold out!
