Re: Tiny laptop for Max/msp

How about a Thinkpad x230? 12.5" Screen (the IPS one is waaaay nicer), quite okay Batterylife, a good CPU, and often sold with 8GB and an SSD on ebay. Best thing: they are cheap as chips. :75: They most likely will have some blemishes, as a lot of them are leasing devices, but I really like them. (a...

Re: Erica Synths SWAMP - the Wogglebug-inspired DIY module

Thanks for the replies. I ordered some from ebay yesterday, will be here in a month or so. By chance, a friend told me he had some lying around, and he gave me to them, as he doesn't need them - so he gave them to me! He isn't quite sure which type they are, but they have the same markings as the on...

Re: Erica Synths SWAMP - the Wogglebug-inspired DIY module

As a little treat for myself, I ordered the partial kit for the erica synths bbd and the swamp :sb: I just stumbled over one problem: Expensive Vactrols. 7€ for one hurts a bit if you need 3 of them. What do the Vactrols on the Swamp do? I took a look at the schematic but am not quite getting it. Wo...

Very exciting stuff. I wonder, is that VCO digital? Seems like it has some really excellent features for the price. I really like those clear/light up trimmer pots that they're using on these. Looking forward to seeing what else comes down this line. Just had a look on their website, seems to be an...

Does the varying voltage you measured on the pot also appear on pin 17 of the microcontroller? Will try that tomorrow, thanks for the tip.

Hi, I just found out that the density knob on my Clouds does not do anything.... The rest of the module seems to work normally (freezing and the other stuff works, only the density seems to have a problem.) The pot works (measured with potentiometer). The Stm32 gets slightly warm to the touch, but n...

Flux really helps. Also, I found solder wick to be immensely helpful. When "normal" soldering with flux does not work, I will drag solder all the pins, put some more solder onto the joints, put the wick onto the bridged joints and heat it with my iron (small chisel tip, btw.). It will leave just the...

Thanks for your quick answer! Am I reading this output correctly as a successful flash? Yes. Okay nice, so at least I did not fry the stm32 as it seems. I will get to scoping tomorrow. We´ll see what comes out. What really baffles me is that the led really do nothing at all, even after a power cycle...

Hi, I built myself a MI Clouds, but after successfully flashing(?) the stm32 via the stlink-v2 nothing happens.

Yeah, I discovered that in the data sheet. And that one is the correct one? Or is it supposed to be the MM(latching) variant? Sorry for the confusion.

MI Clouds Freeze Button

Hey People, quick question: I am building a MI Clouds right now and I am wondering if the Freeze-Button (so SW1 in the bom, or E-switch LP4OA1PBCTG) is supposed to be a momentary or a latching button? Or is the latching happening in software? If it would be the latching variety the BOM would be inco...

(Hope this thread is okay for this)

I am looking for 3 e-switch LP4OA1PBCT* (I don't care what color) in Europe, as it seems to be quite unobtainable without paining 15€ or more for shipping.

Hi People, is there an alternative part for SW1? It seems to be quite hard to get in Europe (Farrell wants 15€ for each order, as it is an order from US-Stock), and mouser did not have the green one when I placed my order (the first thing I read after ordering was about the different colours :doh: )...

You just have an unusually strong aura. :zen: If it was your body heat, and not from contact with either transistor, it would show up in both of them at the same time. You don't need a box. A fan helps. So do plastic tweezers for handling the parts. My little matching rig (Fritz method, built on st...

I think I am too stupid for this...when I move away from the box that contains the circuit (normally I am sitting like half a meter away from it), so further than normally (a meter or so) values shown on the multimeter change drastically (3-5mV), and if I move closer, it jumps back to the old values...

The transistors are extremely sensitive to temperature changes. I wouldn't use a fan to blow air over them. Reason is that even though the volume of air going over the transistors is going to stabilize the temperature somewhat there could be changes in that air's temperature going into the fan. I t...

Its possible to drill acrylic, but one has to be super careful. But one nice feature of thin(-ish) acrylic, so up to 5mm, is that you can use a laser cutter to work on it. If you have a makerspace/hackspace around they might have one. And that makes working with acrylic a breeze.
