Re: Poll - favorite STM32F1 board for stm32duino 08/2107

Hi all, I voted for the maple mini just as "reference design" because i like "integrate" it in other custom stuff. An example is the project I'm playing on... the "CPLD Fun Board": K2eCRUF-dX0 The STM32F103 MCU (maple mini) is used as "stimulus generator" for the CPLD (and as 8/36MHz clock generator...

Hi, I've a Rigol MSO2072A. It should be hackerable too... but I haven't done it for now... (it came with all the sw options included for free... it was a special offer...). I wanted an LA too so I've chosen this one. Here some photo and video using the LAN remote control (very useful...) and some ad...

Re: Making your own pcb's.

About solderpaste and hot air gun... I usually use a cheap solderpaste syringe (no stencil), and often is a little "outdated" too... I found that with a "soft" PCB preheating made with a common hairdryer for a couple of minutes before apply the solderpaste, it helps a lot the adhesion to the pads an...

Total cost (incl shipping) was 25$, for a protopack of +-10 of 10x10cm pcb's (i received 12). My reason for g...

Nice! What CPLD you work with?
Ok I see Altera on the Jtag..
Hi, I've used an EPM240T100C5N (Altera Max II CPLD). It is the cheapest CPLD with a decent numbers of elements I've found "around" (about 1$ each)...

The whole thing should cost about 5/6$ (PBC not included).

My first PCB at ELECROW...

Hi all, this is my first test of the Elecrow service, using the 5pcs 2-layers PCB at 4.9$ offer (max 10x10cm). https://farm5.staticflickr.com/4254/35074107154_35c8d967ac_k.jpg The PCB was designed using Kicad with a minimum track width/clearance of 7/7 mils. The total cost was 4.9$ + 6.42$ (shipment...

Re: A 4$, 4ICs, Z80 homemade computer on breadboard: Z80-MBC (Mobile Breadbord Computer)

Are you planning on selling those as a kit? Hmmm... I don't think to have the time to set up a "business" on this thing. I know that it probably has some "potential market", but I prefer spend my limited spare time to "play" with other things... :lol: I want continue a "paused" project of a "Low co...
