good idea! i will try this as soon as possible...maybe the two siliconne won't get fusioned...

new experimentations: i've tested to warm the "fimo liquid" only 10 minutes, then only 5 minutes (instead of 20 minutes): same result, this product is too hard in all case :( then i've tested with colored material: i don't find the result really beautiful... then i've tested to backlight it, and here too the result is bad, the light don't go trough the material when it's colored, and when using a clear cap, you can see the source of the light... so: it's finaly not the appr. material to do rubber caps.... sorry for this useless topic!

in fact the problem is that you feel the "click" of the tact switch too... it's a way the pads are done on MPC and others: finding a conductive material to put back side the pad won't be a problem i suppose, and maybe the pcb can be done with standart method ?

hi, :( finaly, my little cap is really harder than expected (i've let it dry one more day and it become harder, so now you really have to push on it hardly to see that is "rubber", so in fact only the "touch" is slightly different from the resin caps :( it's not enough "rubber" in my opinion... as i've paid 8 Euros for 50ml of this material, i won't be abble to do a lot of other test...grrrr...i will look for a more appropriate material (for the while ,i've found a that a clear silicone exist, but it's impossible to mold it in my silicone mold (fusion)... ...still on the fight ;) btw: i've tested a mpc style pad done with my standart silicone with some tact switch, but the result is not good (you "feel" the tact switch through the pad). so i've un-mounted my MV8000 drum machine to see how are done the pad: it's done with a conductive "serigraphy" engraved on a pcb and the back side of the pad hold a part of conductive material...i don't know if it's easy to do such a thing...

Hi TK, my seq use cheap buton, so i will test that too...

hum...finaly, this product appear to be less soft two hours after getting it out from the oven, i will try to warm it less than this first time...it's still soft , but not enough in my opinion for doing mpc style pads..using directly the RTV silicone will be better for this purpose (i've already do test that lead to great result, the only thing that stop me is that i can't find appr. mold - if someone own some square plastic box that can be used for that...). the advantage of this product is that you can do transparent soft button, to be used with a backlight LED...

;D

salut, pour les alims symétriques 2*(x)Volts, il existe un kit en vente chez gotronic: http://www.gotronic.fr/catalog/kits/alimentation.htm c'est le kit "Kit K8042" l'appli MIDIbox CV est dispo ici: http://www.ucapps.de/mios/midibox_cv_v1_1.zip

... now i will try to make some blue ones ;) ....the result tonight or tomorrow...

hi, i've just posted that: http://www.midibox.org/forum/index.php?topic=7395.0 wait for the future development...maybe my caps will fit your needs (but i don't think i will do square ones..but why not...)

salut, je viens juste de réaliser mon premier bouton en plastique souple et transparent, c'est encore en phase de test: http://www.midibox.org/forum/index.php?topic=7395.0

Hi, ;D ;D ;D ;D ;D ;D now are coming the first clear rubber buton!!!! it's a macro photographie, so all defaults look bigger than they are in reality...it's my first test, now the material just need to be a bit colored... but that's a good start!!!! the material used is called "fimo liquid", the mold are done with a special silicone that support high temperature (the material need to go to an oven)...all this material are a bit expensive, so i will only do other test if people are interested by such parts.. i've to do some more calculation for the price but i think i can keep my money back selling the caps for 0.5 Euros/part...it's a bit expensive but i've to pay the "research and dev" section of my multinational company! ;)

thanks for the answer ! i don't have a scope... :(

Hi, i'm starting to play with the analog toolbox app but before spending many hours to program what i need, i want to be sure that what i'm doing won't lead to performance issue: so, it's what i've done for the while: instead of a static configuration, the Aouts can be modulated by all available source (midi, lfo1, lfo2, eg, pot) depending on a din event (to make it more clear: you press a buton to select from which source the Aout will be modulated ) here is a portion of the code i've started (it works): so, does such a programmation with a lot of "if" and "else" will be nefast to realtime performance i'm planning to make the LCD always displaying which modulation is used...same question.. thanks

hi TK, another wish or suggestion : the group selection with the F4 button works fine but there is a limitation: if we want to edit for example 2 tracks at the same time with for example the transpose function (great display;)), we are limited to tracks of the same group...don't worry, i don't plane to transpose all 16 track at the same time ;D...but maybe it could be possible to implement an "group independant" track select function. maybe holding the "mute" bouton then pressing on appr. GP buton?...

don't worry, for the while i remove the bubble just with à tiny part of metal, one by one as i'm filling the mold...less dangerous....maybe when i will have sold 2 or 3 thousand of caps , i will invest in a dedicated pump ;D the most dangerous things for the while are the vapors...if you plan to use this technique, please spend some bucks for a good mask !

salut, ouais sans problème, pour le prix: 2 euros les dix caps avec LEDs (il faut me dire si tu veux que les caps eclaire en jaune-orangé ou en vert) et 1.5 euros les 10 contacteurs. pour les frais de port, 1.5 euro suffisent pour une lettre à bulle standart et jusqu'à une trentaine de bouton. soit pour dix boutons complets ,frais de port inclu : 5 euros les caps font exactement 10mm de diamètre pour env. 8mm de haut.

salut Goule, en fait ce sont les caps qui sont bleus, et comme j'ai mis dedans des leds jaunes et vertes, il s'éclairent en jaune ou vert (la couleur de la résine n'influe pas sur la couleur de la lumière...) Je peux en faire avec des leds Bleues dedans, mais dans ce cas il faut me fournir les leds (j'en ai pas trouvé à un prix raisonable pour le moment, et comme elles valent assez cher ,je suis pas assez fortuné pour l'instant pour avancer les sous) pour la grosse molette, ce que tu vois sur le post, c'est l'original que j'ai tenté de mouler, mais sans succés pour l'instant, en fait la seule chose que je puisse faire, c'est une molette ou une datawheel mais sans le perçage pour l'enficher, perçage que tu devrais alors faire toi-même...pour ce qui est du bleu, pas de problème ;) non, je suis sur bordeaux. pour la vente, il suffit de m'envoyer un chèque à l'ordre de notre asso, et j'envoie les boutons.. tu peux utiliser n'importe quel type de "tact switch", ce que je propose avec sont ceux là : http://rocky.digikey.com/WebLib/C&K%20Components/Web%20Data/PTS%20Series.pdf ce sont les "PTS125SM85" à la dernière page du pdf. Ils ont l'avantage d'être les plus larges, c'est donc plus simple pour coller les caps dessus. voilà ...

si t'es pas un peu calé (beaucoup même), ça risque d'être trés dur de re-interfacé totalement un cpu, pour ce qui est du chipset sonore, il faut que tu te plonge dans la datasheet pour savoir quels protocoles il utilise etc...

salut, je viens juste de réaliser des caps avec leds vertes, voir le post sur la partie parts archives. j'ai reçu les tact switch, donc je propose maintenant le kit complet de 10 caps plus 10 tact switchs pour 3.5 Euros. si vous voulez des caps sans leds: 1 Euros les dix... voilà , a+

hi, i've tested the caps with green leds, the result is really cool!!: the caps are blue when not lighted and really green when on!! :) off: on: for those who already ask me for caps, check your mail or your PM.. for the others: i can do caps for a great price: for the colour of the caps, i can do them blue, blue-green or white "cream", test with other colour don't works for the while. I can't do red lighted ones cause i can't find red leds that are enough short to fit the cap...if you wan't multi-colour or blue leds, i've not enough money to order them by myself, so it's possible only if you send me the leds before. -the 10 caps with leds (yellow or green) for 2 Euros -if you don't need lighted buton: the 10 caps without leds :1 Euro (in this case you have the choice between two type of caps: ) -the 10 Tact-switch that fit with them for 1.50Euros (so you get 10 lighted butons for 3.5 Euros) -the shipping cost with standart mail won't exceed 3 to 5 Euros, depending the country where you're living, for France ,1.5 Euro is enough!) note: i don't do that in a commercial way, i've first to get my investissment back, and if there is any benefice, it will be used to do new molds ;) re-note: for the datawheel, the molds don't work, what i can propose if there is enough people interested is to try to mold only the upper side of a datawheel, and let people drill by themself the hole on the back side.

désolé, aucune idée pour ça, peut-être pose la question dans la partie anglaise du forum (parts archive)...

there is 7mm between the dot and the top of the cap, as the travel of the tact switch is less than 1mm, there is still about 2-3mm of empty space even if you use 4mm panel... but that true, it could be better to add à non conductive sheet on the back side of my panels.

the travel of the tact switch is really short so there is no problem, but your idea is good...

hi, no, they are hard.. no, that would be too much work if it was needed to polish them one by one ! here are the one with a red led ( i will take better pic tomorrow-with day light): and the cap with the tact switch:
